By capturing all hydrocarbon vapors, VRSA eliminates flaring and reduces CO2 emissions to

ZERO while adding $$$ to the bottom line. Flaring wastes revenue and increases pollution.

VRSA SOlVES COnVEnTiOnAlVAPOR RECOVERy PROblEMS

Problem: Compresse rc rocaro vapors

coese a ute te compressor ue o resut

premature coect ro aure.

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.

Problem: Costat stopp a start o covetoa

cut a create wear o mecaca eupmet tat ote

resuts ost proucto.

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 emis-

sions separator through the compressor and back to the

emissions separator. Also, the VRSA controls the tank

pressure thus eliminating the possibility of tank col-

lapse or oxygen ingress due to vacuum.

separator where they are returned to storage.

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.

Problem: We puer t sstems restart, vapor

The VRSA features a slug-containment vessel that controls

the release of vapors to match the compression capacity.

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 VRSAProcess 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.
