Pumps and valves are used to maintain refinery processes continuously without sacrificing blend accuracy or quality. 10% to 15% of the capital investment in a refinery is for pumps and valves. Using an incorrect pump and valve layout may result in financial loss due to wastage and equipment damage. An incorrect layout may also have an adverse outcome for the safety and environmental concerns of a refinery. A refiner should be able to prepare an efficient and cost-effective valve layout and instrumentation for a better blending system. This topic will discuss typical blenders, required automation of field equipment; review of location, purpose, role in automation, and management information of all field equipment, lineup equipment; instrumentation; manual valves; motor-operated valves; pumps; pressure controllers; flowmeters; flow controllers; etc.
