Abstract

Disclosed is a process for recovering power from an FCC product. The dry gas is combusted and combined with FCC regenerator flue gas to raise the power recovery capability of the flue gas. The flue gas can be used to generate electrical power or steam. Alternatively or additionally, dry gas from an FCC product stream is separated and delivered to an expander to recover power before combustion.

Description

technical field [0001] The technical field of the invention is power recovery from fluid catalytic cracking (FCC) units. Background technique [0002] FCC technology, now more than 50 years old, has undergone continuous improvements and remains the primary source of gasoline production in many refineries. Gasoline, and lighter products, are formed from the cracking of heavy (ie high molecular weight) low value hydrocarbon feedstocks such as gas oils. [0003] In the most common mode, the FCC process includes a reactor closely connected to a regenerator, followed by a downstream hydrocarbon product separator. The hydrocarbon feed is contacted with a catalyst in the reactor, which cracks the hydrocarbons into smaller molecular weight products. During this process, the catalyst tends to accumulate coke, which is burned off in the regenerator. [0004] The heat of combustion in the regenerator typically produces flue gas at a temperature of 677°C to 788°C (1250°F to 1450°F) a...
