CRYOMAX® NGL recovery processes 3

Adding Value through NGL recovery

CRYOMAX® NGL recovery technology is a family of cryogenic processes for the recovery of ethane or propane from associated or non-associated natural gases, or other methane-rich streams such as petrochemical or refinery off-gases.

For more than four decades, the design and construction of large gas treatment plants including NGL recovery has been one of Technip’s core businesses. All stages of project development have been handled by Technip’s engineers: conceptual and basic design, turnkey engineering and construction contracts, troubleshooting, plant surveys, revamps, debottlenecking.

Building upon this experience, the CRYOMAX® family has grown to reflect the needs of our clients for ever more efficient and flexible NGL recovery processes. Feedback from start-ups and other opportunities to match operational data have provided confidence in design methods.

Development of new CRYOMAX® schemes is part of our multi-year R&D

program which is updated regularly to match market trends.

CRYOMAX® NGL recovery technology is now proposed on the majority

of Technip LNG and FLNG projects where it allows efficient production of

ethane and propane as make-up for mixed refrigerant processes even when

processing very lean gas and heavy end scrubbing.

CRYOMAX®, Technip’s family of cryogenic NGL recovery processes

CRYOMAX® is now available under a stand-alone license to answer the demand

for independent selection of best NGL recovery technology at an early stage of

project development. The experts and the development teams for the CRYOMAX®

suite of technologies are hosted in our Consulting Services and Technology (CST)

organisation in Paris.

CRYOMAX® NGL recovery processes4

A CRYOMAX® solution for every NGL recovery project

CRYOMAX®: high performance, proven design

The basic principles used in CRYOMAX® processes include the following:

The use of a recovery tower, fed with one or more reflux streams that are not obtained by the partial condensation of the overhead vapour.

A combination of well proven equipment such as turboexpanders, aluminum plate-fin or shell and tube heat exchangers and distillation columns.

Thorough thermal integration, whereby thermodynamic irreversibilities are minimised by limiting the temperature approaches for heat exchangers and by reducing the thermal gradients for fractionation columns.

Good recovery selectivity and optimised thermal integration, resulting in lower utility consumption and investment costs.

CRYOMAX® NGL recovery solutions

CRYOMAX® achieves a high NGL recovery rate whilst reducing the investment cost per ton of produced ethane or propane as compared to conventional expander plants.

Today’s CRYOMAX® suite answers the need for improved processes as the gas market develops and new demands arise:

High ethane and propane recovery rates

Reduced energy consumption

Flexible ethane production to match downstream user requirements with consistently high propane recovery

Tailor-made schemes for optimised aromatics and C5+ removal in LNG plants.

Numerous CRYOMAX® NGL recovery schemes are available to match project objectives. Each scheme can be adapted to our clients’ requirements and can be optimised for maximun project profitability.

CRYOMAX® DCP - Deep Propane Recovery

The Dual Column technology, CRYOMAX® DCP, is one of the most efficient schemes for deep propane recovery (99%+). Propane production cost is approximately 20% lower than for a conventional turbo expander process.

CRYOMAX® MRE & DRE - Deep Ethane Recovery

The Multiple Reflux technology, CRYOMAX® MRE, and the Dual Reflux technology CRYOMAX® DRE both provide a deep ethane recovery up to 99% along with 99% of propane recovery. Thanks to the multiple reflux, the energy consumption is reduced compared to other NGL recovery processes at constant recovery.

CRYOMAX® Flex-e - The ideal solution to feed an ethane steam cracker

The high flexibility Ethane recovery process, CRYOMAX®Flex-e, allows matching any ethane recovery from low (2%) to high (90%) while keeping high propane recovery of 99%. This provides flexibility with respect to the downstream ethane user without affecting the profitable recovery of propane in the NGL. Production costs are about 20% less than a conventional process. Project economics are improved by high propane recovery at all times.

It is also attractive for making variable quantities of ethane refrigerant make-up in a natural gas liquefaction plant (LNG).

CRYOMAX® DEER - Efficient, non-disruptive debottlenecking

CRYOMAX® DEER (Dual Expansion Ethane Recovery) is a cryogenic process technology for high (95%+) recovery of ethane and heavier hydrocarbons, particularly well suited for the debottlenecking of an existing NGL recovery plant. The addition of a second warm turbo expander allows an increase in capacity or recovery rate with minimum disruption of operations.

Profitable alternatives for LNG train NGL recovery

CRYOMAX® LNG - Improve your LNG plant revenue by high NGL production

CRYOMAX® for LNG allows high levels of ethane recovery from LNG trains equiped with a scrub / column. Deep recovery of NGL is possible from a new or an existing LNG train.

Feed gas pre-treatment is ensured by the steps already required for liquefaction. This process is reversible in that the LNG unit can be operated with or without the NGL recovery unit. Capital investment per ton of ethane is approximately 70% compared to a stand-alone plant located upstream of the LNG unit.

CRYOMAX® FRAC2 - LNG train feedstock preparation to optimise product yields

CRYOMAX FRAC2 produces two highly fractionated products: ready to liquefy C4- and stabilised C5+. It is suited when the refrigeration system used in liquefaction is not based on mixed light hydrocarbons refrigerants or when LPG is not marketed as a separate product.
