Increase $$$

Zero CO2 emissions from Flaring

By capturing all hydrocarbon vapors, VRSA eliminates flaring and reduces CO 2 emissions to ZERO while adding $$$ to the bottom line. Flaring wastes revenue and increases pollution.

VRSA captures all hydrocarbon vapors from the tank, so that vapors are profitably utilized rather than wasted at the flare. For most new locations not equipped with a flare, the VRSA’s demonstrated reliability will preclude the need to install a flare under current regulatory requirements.

VRSA protects the compressor by using an eductor to capture and compress the rich vapors to about 25 psig prior to introducing them to the mechanical compressor. The non-mechanical eductor eliminates one mechanical compression stage and the need for a cooler in the process. Any liquids condensed in the eductor compression stage do not affect the eductor. The VRSA further prevents condensation in the compressor by controlling vapor temperature and/or composition in each mechanical stage of compression.

The VRSA engine and compressor run continuously and load free during low vapor production cycles. Cold starting is eliminated and the engine and compressor remain warm as the VRSA circulates gas from the emissions separator through the compressor and back to the emissions separator. Also, the VRSA controls the tank pressure thus eliminating the possibility of tank collapse or oxygen ingress due to v acuum.

VRSA eliminates any potential of a runaway recycle by precise control of the process temperatures and pressures.

The VRSA Process, when used in conjunction with other Engineered Concepts products and industry accepted practices, precludes the need to open the thief hatch when gauging or unloading the tank. The VRSA Process thus provides the means to eliminate a source of oxygen contamination of the recovered gas stream and a source of hydrocarbon emissions to the atmosphere.

A VRSA equipped with a passive pumping system pumps the condensed liquids from the lines to the emissions separator where they are returned to storage.
