Refining temperature

Web1. jan 2015 · Temperatures in refining processes are controlled by heat exchange, furnace firing, and flow of the reactants for the most part. Temperature control is thus reduced essentially to flow control of feeds, internal fluid flow, or fuels – all flow control issues. Hence, the control of temperatures mimics the flow control discussion. Web16. mar 2024 · Petroleum refineries are complex and expensive industrial facilities.
