Enhanced Control

There are many disturbances that can affect efficiency and stability at a modern ammonia plant. For example, a feed gas rate may be changed several times a day to manage a daily quota of gas. Changes in primary reformer operation can affect methane leakage into the synthesis loop, which in turn requires changes in purge rate to hold loop pressure or inert levels at the desired value. Certain energy efficiency methods also have the potential to cause disturbances throughout the entire plant.

The impact of these disturbances can be managed with a control strategy that focuses on these primary objectives:

  • Increase throughput
  • Reduce loss of hydrogen and nitrogen to purge
  • Reduce utilities consumption, both steam and fuel gas
  • Provide improved operating information

Pushing unit processes to their optimal conditions increases plant efficiency and profitability. Enhanced, progressive controls are often employed to drive the operation of an ammonia plant to its most profitable running condition.  There are 8 great benefits for enhanced control at ammonia plants.

Top 8 Control Benefits

  • More consistent product quality
  • Energy (fuel and steam) conservation
  • Greater operating efficiency
  • Improved operating stability
  • Faster line-out following feed changes
  • Reduction in constraint violations (metallurgical, catalyst bed, etc.)
  • Elimination of off-specification products
  • Better operating information & operator understanding

Optimum outcomes for methanol

Yokogawa understands what profitable methanol productions entails – low cost of feedstock, high energy requirements for steam reforming, high pressure for cooling, compression for catalytic reaction, and distillation for purification of methanol to allow best conditions for optimum production outcomes.

We provide solutions that enhance safety, ensure accurate and reliable operation, and increase plant efficiency across every facet of your production activities. As a key element of this crucial industrial process, water retention/discharge, and the smart management of it, can influence both process efficiency and sustainability results.

Application Note

Hydrogen is the simplest and smallest atomic element. Water, acids, bases, and the immense family of organic compounds all contain hydrogen. Even though hydrogen is not corrosive, it can cause problems for pressure transmitters through Hydrogen Permeation.


Electrolysis plants create hydrogen and chlorine from a brine solution. Chlorine gas generated from the anolyte of the electrolysis tank generally contains between 0.5 to 2.0 vol% H2O. The sample is then cooled and filtered to remove brine, subsequently coming out as wet chlorine gas. The wet gas is sent to a drying tower where it is treated with sulfuric acid to get moisture down to the ppm level. 


Enhance the efficiency and safety of your vapor recovery systems and flare/vent headers with Yokogawa's cutting-edge Tunable Diode Laser Spectrometers – the TDLS8000 and TDLS8220. Elevate your oxygen measurement capabilities with our interference-free analyzers, providing direct measurements. Experience unparalleled reliability, ensuring minimal upkeep and secure operations without the need for system shutdowns.


Yokogawa’s Process Liquid Analyzers series help pigment producers achieve a more reliable and accurate analysis of pH during industrial bioprocesses, improving product quality with less total operation costs.


Heat exchangers are devices that provide the flow of thermal energy between two or more fluids at different temperatures. Heat exchangers are used in a wide variety of applications. These include power production; process, chemical and food industries; electronics; environmental engineering; waste heat recovery; manufacturing industry; and air-conditioning, refrigeration, and space applications. Yokogawa offers a means to control heat exchanger leakage and prevent costly maintenance, repair and downtime with an easy-to-use, virtually maintenance-free condensate conductivity measurement method.

This paper discusses real industrial examples in which the sitewide utilities system of refinery and petrochemical Sites are optimized with a real time, on line, industrially proven software. Experiences gained during more than 20 years of industrial projects deployed worldwide are commented (Refs. 1 to 10 are related to some recent projects). Main project steps are explained and critical details to be taken into account to assure successful use and proper technology transfer are presented. Specific case studies will be discussed in the paper. 


Big and complex industrial facilities like Refineries and Petrochemicals are becoming increasingly aware that power systems need to be optimally managed because any energy reduction that Operations accomplish in the producing Units could eventually be wasted if the overall power system cost is not properly managed. However, process engineers always attempted to develop some kind of tools, many times spreadsheet based, to improve the way utilities systems were operated. The main drawback of the earlier attempts was the lack of data: engineers spent the whole day at phone or visiting the control rooms to gather information from the Distributed Control System (DCS) data historian, process it at the spreadsheet and produce recommendations that, when ready to be applied, were outdated and not any more applicable. 


Industrial process automation has evolved significantly over the years, playing a pivotal role in improving operational efficiency, safety, cost reductions, and ensuring product quality. Traditional automation systems, however, often relied on proprietary, closed architectures, leading to vendor lock-in, interoperability challenges, and limited adaptability to changing business needs often required for enterprises to expand or progress. Industrial process automation has evolved significantly over the years, playing a pivotal role in improving operational efficiency, safety, cost reductions, and ensuring product quality.

  • The movement away from proprietary, closed architectures
  • How OPA avoids vendor lock-in and interoperability challenges
  • Changing business needs requiring flexible systems to progress
