Dynamic modelling and simulation for process

Traditionally, process engineers often face the possibility of FEED and detailed engineering designs exceeding limits due to unforeseen circumstances, for example, with complex control systems, operational philosophies and procedures. Potential problems during plant start-up, emergency shutdown and various turndown conditions may not be identified in advance due to insufficient information on plant behaviour. Similarly, the effect of various process controllers on plant operations during transient events may not be completely understood. The selection and operation of turbo machinery is another critical area. Rotating equipment is often carefully scrutinised to avoid setbacks, such as compressor surges or start-up difficulties due to undersized drivers that result in depressurization, etc. Dynamic simulation studies can successfully address these problems. The use of such studies is now an established best practice to accurately assess these transient scenarios and develop reliable and cost-effective solutions.
