AUTOMATION OF OIL AND GAS REFINERY PROCESS USING PLC & SCADA
Yokogawa has a wealth of experience in every part of the oil and gas business, from offshore and onshore facilities to pipelines, terminals, and deepwater operations. We provide solutions that enhance safety, ensure accurate and reliable operation, and increase plant efficiency. The upstream industry includes offshore and onshore activities including wellhead automation, fractionation, completion, and separation to recover and prepare underground or underwater crude oil and natural gas.
As petroleum is brought to the surface, it must be separated prior to transport. Primary and secondary separation stages commonly distribute gas flow, water flow, and oil flow in three phase separation. Gas movement requires pipeline and can include a fractionation process in the upstream stage prior to movement. Liquids can be placed into a tanks or pipelines and sent for processing, requiring accurate level measurements.
Offshore exploration and production requires maximum uptime under harsh conditions. Manned and unmanned facilities need reliable integrated control and safety systems ICSS with advanced remote monitoring capabilities.
Yokogawa has state-of-the-art technology and extensive experience in executing offshore projects of all sizes and automation levels of complexity. The right pipeline control and instrumentation can make a huge difference in terms of performance and profitability.
Yokogawa has dedicated technology that can optimize the performance of all elements of a pipeline solution, including compressors, pumps, valves, and intermediate storage and distribution facilities. Yokogawa total solutions include not only the well site, but also the injection, pipeline, compressor station, and the process plant facility.
Our experience for these applications can be integrated to optimize the overall operation capability and maintainability.

INPEX is engaged in projects all over the world, in a total of 29 countries, including Japan, where it operates a gas production plant near Oyazawa, a town in Niigata prefecture. Yokogawa provided integrated control and safety system to Banagas's CGP-3 gas processing plant.
The company operates as a throughput service company providing the services of processing and transmission of gas to the power generation sectors and various customers. Saudi Aramco's operations span the globe and the energy industry. The world leader in crude oil production, Saudi Aramco also owns and operates an extensive network of refining and distribution facilities, and is responsible for gas processing and transportation installations that fuel Saudi Arabia's industrial sector.
An array of international subsidiaries and joint ventures deliver crude oil and refined products to customers worldwide. Mobil Oil Indonesia MOI identified Yokogawa as its vendor of choice for all natural gas exploration installations in the north of Sumatra. In addition to onshore fields, NAM operates manned platforms and four unmanned monotowers in 19 offshore locations.
These connect to a pipeline network that comes ashore at Den Helder. Fluidcom can optimize Chemical injection systems, to achieve both high asset integrity as well as minimizing OPEX. Fluidcom combines Valve, Flowmeter, Actuator and Control Software functions to make an all in one full-automatic flow controller which can achieve long term chemical injection stability. DP Level transmitter configuration can be very time consuming.
This dramatically lowers communication fees. Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.
One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates. The major methods of improved oil recovery are water flooding and steam injection. HART communication is a means of transmitting multiple signals by superimposing long-standard mA DC analog signals on digital signals. The paperless recorder DX series instruments allow you to determine temperature and humidity, and manage the results as manufacturing and quality data at a reasonable cost with a simple configuration.
Reverse osmosis RO is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. Floating-point format calculations have enabled physical quantities in engineering units to be used in calculations.
Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry. The client wanted to monitor the pressure of the gas well at offshore platform remotely to reduce maintenance cost and increase safety of maintenance personnel. Remote leak detection for pipe line was needed to meet new environmental statute. However cabling earthwork is strictly restricted to protect land environment. The client wanted to monitor the injection gas pressure of gas lift remotely in central control room.
Antitheft measures are needed to install new equipments and cables. A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.
To defray energy costs, many industrial plants have their own boilers to generate steam in order to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels.
Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional.
The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management.
Rationalization is one of those critical steps. Tuning PID controllers can seem a mystery. Parameters that provide effective control over a process one day fail to do so the next.
The stability and responsiveness of a process seem to be at complete odds with each other. And controller equations include subtle differences that can baffle even the most experienced practitioners. The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.
The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.
The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.
In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action.
Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.
Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold.
With capital budgets tighter than ever, users instead focus on operational budgets where cost cutting is also a key concern , or on automation investments with a very rapid return on investment. In today's dynamic industrial marketplace, the only constant is change.
Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions. Migration of a refinery's DCS provided an opportunity to reconfigure and consolidate the control rooms and operational management system. Digitised data can be used for automated analytics in predictive maintenance and root cause analysis applications.
Cloud-based wireless sensing enables safety, reliability, and profits through widespread asset monitoring. The wireless standard LoRaWAN enables wireless communications and digital transformation over long distances, supplementing in-plant wireless networks such as ISA Process plants are run according to operational procedures. These procedures consist of a set of tasks that are executed in a consistent manner to achieve a specific objective, such as starting up, shutting down or transitioning a unit as part of making a product.
Assets and operations will have human-like learning and adaptive capabilities, allowing responses without operator interaction to situations within a secure, bounded domain. Historians provide the data storage, secure connectivity and built-in tools required for implementation of digital transformation initiatives.
Robots have long been used in discrete manufacturing and machine automation applications, and their use is now spreading to address process industry applications. In times of abnormal operations, systems are configured to produce lots of data — humans are not configured to handle or interpret them.
However, when presented with the right information, in the right context, during an abnormal condition, humans are able to do things machines cannot. Asset management plays a key role in operational safety, and it is critical to capture and transmit these data in a secure, digitized way to ensure that they are up to date, accurate and easily accessible. Process automation systems are increasingly connected to IT systems and the outside world, introducing cybersecurity concerns, which can be addressed using techniques such as software-defined networking and monitoring services.
Martin te Lintelo, Yokogawa Europe B. As demand for LNG increases worldwide, players face seemingly conflicting challenges. On one hand, they must expand capacity in different regions, make the business and production as agile and adaptive as possible, and improve operational efficiency.
The LNG sector presents challenges for the automation supplier, particularly in the implementation of automation systems for regasification terminals. Yokogawa Europe's business development manager, upstream oil and gas Martin te Lintelo looks at the handling of the potential automation-related problem areas and opportunities. Partnering with Saudi Aramco, Yokogawa is providing local project execution including testing and implementing a continuing policy of Saudisation.
Many published papers discuss the benefits of subsea HIPPS and many studies show the potential cost-benefit analysis of this technology in deepwater applications. An internet search for subsea HIPPS is informative; however, little appears that discusses the systems already delivered and operating successfully.
What the oil and gas industry needs from SCADA
Industrial organizations in every industry manage countless production processes and transactions every day. Management teams oversee operations, inspect equipment, gather enormous amounts of data, strive to minimize downtime and ensure that everything runs smoothly and seamlessly. Performing these duties manually is a nearly impossible task. One of the most powerful tools for monitoring equipment and processing data in real time is supervisory control and data acquisition SCADA — a control system that makes high-level supervision of critical operations in industries like oil and gas, transportation and manufacturing a much more manageable undertaking. SCADA is a powerful system of hardware and software designed to help industrial organizations in their day-to-day operations.

SCADA implies a highly configurable set of industrial software applications that can be used to support management of almost any form of process production. SCADA is widely applied in the upstream, midstream, and downstream oil and gas sectors. In the upstream sector, its role often is stereotyped as being largely in support of remote data transmission. There are reasons to believe this will change. In addition, owners and operators are recognizing how IT-based automation can productively address even the unique challenges of the upstream oil and gas sector.
Of critical importance, in most of these SCADA systems , are the standard features that include alarms management and emergency response, communications over a variety of mediums, redundancy at all points in system, trend analysis, and remote system access. The powerful scripting language also allows graphing of pump curves. The process of getting oil and gas from the well head production source to the refinery processing facility and ultimately to the consumer usually requires a large infrastructure of pipeline networks. The advances made in oil and gas distribution SCADA technology have significantly reduced the cost for remote telemetry devices and the communications infrastructure required to retrieve data from these devices. This in turn allows operators to remotely monitor, control and optimize their distribution network.
Кольцо снова блеснуло на солнце. Женщина отвернулась. Танкадо, задыхаясь и не в силах произнести ни звука, в последней отчаянной надежде посмотрел на тучного господина.
Начиная с того дня, анонимные переадресующие компании перестали быть для АНБ источником серьезных неприятностей. - Вы сможете его найти? - спросил Стратмор. - Конечно.
Ни за что на свете.
- Она пробежала глазами таблицу. - Уран распадается на барий и криптон; плутоний ведет себя несколько. В уране девяносто два протона и сто сорок шесть нейтронов, но… - Нам нужна самоочевидная разница, - подсказала Мидж. - У Танкадо сказано: главная разница между элементами.
- Она отвернулась. Ее плечи подрагивали. Она закрыла лицо руками.

Но нам известно, где. - И вы не хотите ничего предпринять. - Нет.
- Панк не понимал, к чему клонит Беккер. Пестрое сборище пьяных и накачавшихся наркотиками молодых людей разразилось истерическим хохотом. Двухцветный встал и с презрением посмотрел на Беккера. - Чего вы от меня хотите.
В отчаянии он наблюдал за тем, как расплывчатые фигуры агентов обыскивают бездыханные тела в поисках листка бумаги с беспорядочным набором букв и цифр. - О мой Бог! - Лицо Джаббы мертвенно побледнело. - Они ничего не найдут. Мы погибли.
Три часа. Стратмор поднял брови. - Целых три часа.
- Имея партнера в Америке, Танкадо мог разделить два ключа географически. Возможно, это хорошо продуманный ход. Сьюзан попыталась осознать то, что ей сообщил коммандер.
