Abstract
The invention relates to a process for modifying the VPSA/VSA/PSA cycle to allow for maximum product pressure without the need for a base load oxygen compressor (BLOC) or base load oxygen blower (BLOB), thus supplying low pressure oxygen (3 to 7 Psig) to the end user while at the same time lowering product costs 10 to 30%. The system of this invention preferably employs larger piping runs from the VPSA to the oxy-fuel control skids, larger piping for the oxy-fuel control skid, larger piping for the VPSA, low pressure drop flow measurements, and low pressure drop check valves.
