Adjustable Pressure Phase Separator
The Adjustable Pressure Phase Separator (APPS) is designed to maintain high-quality liquid for on-demand withdrawal at a customer-specified and adjusted pressure. It splits the incoming two-phase flow into separate liquid and vapor streams.
An inlet control valve proportionally controls the incoming flow from the higher-pressure liquid nitrogen source to keep the phase separator full. The vent control valve proportionally controls the gaseous nitrogen venting from the phase separator to maintain the set head pressure.
Key Features And Benefits
- Use on any application that requires high-quality liquid delivery at a pressure that is less than the Bulk Tank or Branch Line Pressure.
- Controls incoming flow from the Higher-Pressure Liquid Nitrogen Source to maintain the set liquid level.
- Back Pressure Regulator Valve maintains user defined set delivery pressure.
