Abstract

An integrated process and air separation process including the steps of: Work expanding at least one first pressurized gas 39 derived from a first process at a first site 1, using work generated by the expansion of the at least one pressurized gas to drive a first air compressor 5 at the first site and removing compressed air from the first air compressor, sending at least part of the compressed air 19 from the first air compressor to an air separation unit 21, located at a second site 2 remote by at least 1 km from the first site, separating at least part of the compressed air sent from the first site to the second site in the air separation unit and removing at least one fluid 37 enriched in a component of air from the air separation unit and sending at least part of the fluid enriched in a component of air to the first site.
