Air Separation Unit With Reboiler, Buffer Vessel And Booster Air Compressor With Engine
Abstract: The conventional air separations units (ASU) for production of compressed oxygen and compressed nitrogen gases entail multiple (3 or more) rectification columns, a main heat exchanger, a pre-treatment auxiliary column and a combination of these features. They (ASUS) yield oxygen levels of around 29% in liquefied air prior to separations. The present invention incorporates a damper to an expansion engine to dually serve as an improvised column, fitted with 6-8 sieve trays and air coil reboiler in bottom section of high pressure rectification column to liquefy process air prior to enrichment in the buffer vessel. The twin features yield oxygen concentrations of 39%, thereby substantially reducing column size for high-pressure and high pressure rectifications and offering substantial savings in overall operating costs.
