PROVIDING GASES TO AROMATIC CARBOXLIC ACID MANUFACTURING PROCESSES

摘要

A chemical manufacturing system includes an air compressor configured t o receive and pressurize a stream of air to a selected pressure, an air separation unit configured to receive pressurized air from the air compressor and generate a stream of oxygen and a stream of nitrogen at selected purity levels from the pressurized air, a chemical generation system configured to receive at least the stream of oxygen from the air separation unit, and a reactant supply to provide a reactant to the chemical generation system. During system operation, the reactant is oxidized to form a product within the chemical generation system . In one embodiment, the reactant is paraxylene, and the chemical generation syst em produces a terephthalic acid product.
