PRODUCT FEATURES
Enerflex has a dedicated engineering and design team, plus the
resources and fabrication capabilities to provide complete cryogenic
processing facilities for deep-cut liquids extraction.
These systems are engineered to dry and recover Natural Gas Liquids
(NGLs) for natural gas feedstock flow rates of 30 to 200 mmscf/d utilizing
the Recycle-Split-Vapor (RSV) process, or the Gas Subcooled Process
(GSP) depending on desired recovery rates. The facilities use turbo-
expanders to achieve an ultra-low temperature allowing recovery rates
of 95+% of the inlet stream’s ethane, 99.8+% of propane and 100% of
the butane.
Enerflex’s core configuration for cryogenic plants includes inlet
dehydration using molecular sieve equipment, cryogenic gas processing
system, and turbo-expander/re-compressor skid. Additional options
such as a hot oil system, pipeline pumps, amine treating, inlet and
residue compression, and refrigeration equipment to meet specific
application demands are available.

PRODUCT BENEFITSEfficient - Custom modular designs result in simplified installation, reduced on-site construction, and easily duplicated designs that speeds up the development of the gas plant. An available inventory of long lead components reduces project lead times.
Flexible - By operating in either ethane rejection or recovery, GSP or RSV technology provides the operator with the ability to maximize plant profits based on economic factors. GSP or RSV offerings operate in either ethane recovery or ethane rejection. We have a wide range of technology solutions to customize a plant to your economic and operational model while maximizing your profits. Enerflex helps you customize recoveries to suit a desired range and offers a process guarantee to mitigate risk.
Choice - We leverage our economies of scale and buying power to source preferred suppliers to provide a greater price advantage and the security of working with vendors you know and trust. This includes the option to integrate controls of choice including Distributed Control Systems (DCS).

Enerflex Ltd. (TSX: EFX) is an international company with
thousands of skilled, customer-focused personnel and carefully
assembled operations in dynamic energy-producing markets
worldwide. Enerflex supplies natural gas compression, gas
processing, refrigeration systems, and electric power equipment
– plus in-house engineering and mechanical service expertise
and full after-market support.
INTEGRATED TURNKEY PROJECT SOLUTIONS
Enerflex’s integrated turnkey project solutions
encompass front end engineering and design (FEED)
studies, design, fabrication, construction, installation,
commissioning, after-market service, operations and
maintenance, and beyond. By working with Enerflex on a
turnkey cryogenic gas plant project you will receive simplified
supply chain processes; reduced interface risks; fastest achievable
timeline from concept through commissioning; cost certainty; and the
confidence that the operating infrastructure will be kept at peak performance
throughout its entire life-cycle.
Enerflex’s integrated turnkey product offerings include:
» Thoroughly engineered facilities;
» Simplified supply chain;
» Civil, earthwork, and concrete;
» Piping and structural fabrication;
» Maintenance of the required equipment;
» Installation of static and rotating equipment packages, and all other associated modules;
» Electrical, instrumentation, controls, and automation;
» Commissioning and full after-market services; and
» Operations and maintenance contracts.
CRYOGENIC GAS PL ANTSWhen combined with inlet treating, NGL fractionation,
TEG dehydration, and residue compression, Enerflex
offers a single point of contact to evaluate the integration
and design of the entire system.
CORE CONFIGURATION
» Molecular sieve dehydration;
» Gas Subcooled Process for
moderate ethane recovery;
» Recycle-Split-Vapor process
for ultra high ethane and
superb propane and heavier
hydrocarbons recovery;
» Stainless steel de-methanizer;
» Brazed aluminum heat exchangers;
» Up to 99% ethane recovery*;
» Up to 100% propane recovery*;
» 100% butane recovery;
» Effective recoveries in recovery and
rejection mode; and
» Designed for liquids rich shale gas.
OPTIONAL FEATURES
» Hot oil system;
» Pipeline pumps;
» Amine treating;
» Inlet and residue compression; and
» Refrigeration equipment.
Enerflex meets or exceeds
industry standard specifications
including ASME code for piping
and vessels, AISC for structural
steel, NEC for electrical, and ISA for
instrumentation.
*Depending on technology
The remaining gas is sub-cooled utilizing de-methanizer overhead
vapor in another brazed aluminum heat exchanger to
provide reflux to the tower.
The de-methanizer tower provides highly effective
separation between methane and heavier hydrocarbons by utilizing the cryogenic
temperatures in the top sections to drive heavier components to
the bottom of the tower.
When the application demands, a mechanical refrigeration system may be provided for additional heat removal prior to preliminary separation of heavier hydrocarbons.
First, the dry gas flows through a high efficiency brazed aluminum heat exchanger for pre-cooling.
Gas enters the unit at high pressure and flows into the molecular sieve dehydration beds for removal of water before flowing into the main cryogenic processing system.

Liquids from the expander inlet separator and warm temperature
separator are directed to the de-methanizer tower.
Liquid product flows into an accumulator before being pumped into the pipeline through a series of booster and high-pressure pumps.
A portion of the gas from the expander inlet separator flows
through the expanding side of a turbo-expander/re-compressor. 5
Overhead gas from the de-methanizer is boosted in the
compressing section of the turbo-expander/re-compressor before
flowing to the residue compression and into the sales pipeline.
