VRSA Increase $$$ Zero CO2 emissions from Flaring
NOW.
VAPOR RECOVERYHAS NOT BEEN economical,effective, efficient and reliable until
Consider, for a moment, the benefits of a vapor recovery system that is truly effective
and mechanically reliable. Who wins?
The answer is EVERYBODY WINS!

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
vapor recover uts (VRU) crease compressor a
ee mateace costs. Co weater starts are especa
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.
Problem: Stock taks are ote ocate ar rom te VRU.

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.

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.

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.
