Abstract:

An introduction is given to the process flow, process parameters and associated equipment of low pressure oxygen system of air separation unit, and an analysis is made of reasons in operation of low pressure oxygen system such as unstable operation of liquid oxygen pump, and ambient air vaporizer being unable to meet the requirement of liquid oxygen vaporization temperature. In connection with existing problems, through two renovations, the problems of low pressure oxygen system have been solved completely, the requirement of stable operation of combustion furnace for sulfur recovery is satisfied, at the same time the operation cost of the low pressure oxygen system is reduced, good economic benefit is realized.
