Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.

Yokogawa has long served customers in the specialty and fine chemicals market. With a market leading batch solution that offers the best in class reliability and flexibility as well as industry experts who understand the complex requirements in designing a batch solution, you can be assured that in your partnership with Yokogawa you will have a system that will enable you to produce products that meet your customers’ needs in the future while maintaining safety and regulatory compliance.

Yokogawa has state-of-the-art technology and extensive experience in executing offshore projects of all sizes and automation levels of complexity.

In the mid 1970s, Yokogawa entered the power business with the release of the EBS Electric Control System. Since then, Yokogawa has steadfastly continued with the development of our technologies and capabilities for providing the best services and solutions to our customers worldwide.

Yokogawa has operated the global power solutions network to play a more active role in the dynamic global power market. This has allowed closer teamwork within Yokogawa, bringing together our global resources and industry know-how. Yokogawa's power industry experts work together to bring each customer the solution that best suits their sophisticated requirements.

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.

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.

Petrochemical companies’ needs are extremely diverse. To come out ahead in today’s highly competitive marketplace, producers are striving to improve quality and productivity. Yokogawa provides tailor-made solutions for these needs based on its long and wide-ranging experience in this field.

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 oil & gas downstream industry has been facing an increasing number of challenges in recent years. These include the changing characteristics of the feedstock to be processed, aging of process facilities and equipment, rising cost of energy, lack of skilled plant operators who can run a refinery safely and efficiently, and the ever-changing requirements from both the market and the customer.

Over the years, Yokogawa has partnered with many downstream companies to provide industrial solutions focused on solving these challenges and problems. Yokogawa's VigilantPlant solutions have helped plant owners to achieve maximum profitability and sustainable safety within their plants.

In the ever changing marketplace, refineries are seen not only as crude processing units but also as profit centers. At the same time, there is a keen awareness of the need for safety at such facilities. A total production solution that encompasses planning, scheduling, management, and control is required to achieve long-term goals for profitability, efficiency, and environmental protection. With years of expertise in the automation field, Yokogawa can bring you affordable total solutions for improved operability and a cleaner world.

Thermal power using coal, oil or gas as fuel accounts for the majority of electric generation throughout the world.

Wastewater treatment plants use many motors, pumps, blowers, etc., and so it is important to reduce their electricity consumption in order to reduce running costs. Yokogawa provides optimum control solutions to improve energy efficiency.

Yokogawa provides optimum solutions to improve the reliable operation of water treatment plants. These solutions include sophisticated technologies, unsurpassed product quality, and extensive application know-how throughout the lifecycle.

Il existe plusieurs technologies sur le marché pour mesurer le débit massique. L'une est le transmetteur de pression multivariable.
 

Les transmetteurs de faible pression sont couramment utilisés dans les systèmes de traitement de l'air.

Yokogawa utilise son capteur digital DPharp pour concevoir un transmetteur pour ce type d’application spécifique

En utilisant l'équation de Bernoulli, les transmetteurs de pression différentielle peuvent être utilisés pour déduire le débit de fluide à travers un tuyau.

A Multi-Sensing transmitter combines transmitters for Differential Pressure, Gauge Pressure, and Temperature into one field instrument.

Des lectures de niveau précises sont essentielles au fonctionnement sûr, fiable et rentable de votre usine. Les transmetteurs de niveau de liquide mesurent la pression différentielle pour déduire le niveau dans une cuve.

Les transmetteurs de pression absolue comparent la pression relative au vide absolu. La pression absolue est toujours une valeur positive.

La pression différentielle (DP) est définie comme la différence entre deux pressions. Les transmetteurs de pression différentielle utilisent un point de référence appelé côté basse pression et le comparent au côté haute pression. Les ports de l'instrument sont marqués côté haut et côté bas.
