Improved cooling system performance begins with data

摘要

Refineries consume large amounts of energy and water to refine crude oil into products.Up to 10% of crude oil's energy content is consumed during processing,and it takes 1.5 bbl of water to process one barrel of crude oil.Refining processes also generate large quantities of excess thermal energy that needs to be expelled into the environment using a once-through or recirculating cooling system.A once-through system draws water from a raw water source and pumps it through process heat exchangers where it absorbs heat and is then sent back to the source.These systems are cheaper to construct and consume significantly less water than recirculating systems,but they may also require more water treatment chemicals and pose environmental risks.
