 Introduction Steam is used in Petrochemical and Refinery complex as the major source of heat. These plants usually have captive power plants to generate electrical power from high pressure steam (HP) in boilers. The extraction steam from Back-pressure turbines then provides the low pressure steam (LP) for process use. The use of steam can be categorized under the following headings: Steam for Power HP superheated steam is used in power turbines and drive turbines to generate electrical power and drive equipment like pumps, fans and compressors. It is also used in Ejectors for vacuum conditions. Steam for Process LP saturated steam is used in process equipment like Reaction vessels, Reboilers, Fractionating towers, Distillation columns and Heat-exchangers. Steam for Tracing LP saturated steam is also used to maintain temperature of various products in Storage tanks ,distribution pipelines and pumps. This steam is also used in product loading/unloading areas for maintaining products at pumping temperature.
