Low-pressure compressed natural gas dryer
LCNG = Low-pressure compressed natural gas dryer
Dual Tower Continuous Duty Purifier
Pressure through 150 PSIG standard. LCNG purifiers are ideal for large gas flow continuous duty service before the natural gas compressor. One tower purifies while the other regenerates. Systems are completely self-contained with pre-wired and pre-piped components.
Operation
Gas enters the prefilter which removes moisture and oil in liquid and aerosol form. The gas flows into left tower for drying, then through the afterfilter, preventing desiccant dust particle carry-over downstream.
While the left tower dries, a captive volume of gas flows through the right tower for regeneration. The blower moves the gas and the heater raises its temperature. The hot dry gas flows through the right tower and absorbs moisture to regenerate the desiccant. The moisture-loaded gas then flows through the gas cooler which condenses the moisture. The coalator removes the maximum amount of moisture from the gas. The right tower is cooled by turning the heater off. After a preset time, the towers switch roles.
