Refrigerants for LNG Liquification.

High purity for high performance that doesn’t stop.

Whether you employ an AP-C3MR, Optimized Cascade Process (OCP), or any version of SMR, i.e., Chart IPSMR, Linde LIMUM Process, the refrigerant you use for liquefaction impacts your LNG operations. Most refrigerants contain contaminants that cause adverse chemical reactions and can slow down or shut down a plant. However, our high-purity refrigerants optimize plant and business performance.

High-purity refrigerants:

Improve plant safety
Increase production rates, uptime
Reduce energy costs
Reduce environmental footprints

Our hydrocarbons are the world’s purest and include:

R290 (Propane)
R601a (Isopentane)

Why Does Purity Matter?

Contaminants Negatively Impact Safety, Productivity, Efficiency

Refrigerant contaminants can lead to gas leaks, equipment failure, and wasteful power consumption.

Contaminant	Impact
Water	Causes piping corrosion and possible lube oil breakdown in compressors. Freezes and expands, causing pipes to rupture. Generates ice shards that pass through the system, damaging pumps and seals.
Mercury	Causes metal to be brittle by forming aluminum amalgam, leading to stress fractures.
Ethane (High-pressure gas)	Increases horsepower by placing unnecessary demand on the compressor drive and discharge coolers. Limits natural gas flow rate to offset the additional load. Causes a high-pressure trip at the HHP stage.
Butanes and Heavier	Requires higher refrigerant circulation to meet the targeted cooling temperature.
CO2	Causes corrosion and freeze-ups in the presence of moisture.
Other impurities (neopentane, etc.)	Causes freeze-ups in the Mixed Refrigerants (MR) loop.

Electrical Cost Savings

LNG plants using high-purity refrigerants realize substantial cost savings.

Average Electric Savings*

Low-Purity vs. Diversified CPC High-Purity Refrigerant

$1.26 Million savings per year, per train

* LNG plant utilizing C3MR process and a 100K horsepower compressor; producing 5 Million tons annually with an electricity cost of $0.06 / kilowatt hour

Compressor Performance

There is a direct correlation between refrigerant purity and compressor performance. The diagram below is a typical high-efficiency centrifugal compressor performance curve. With impurities like ethane, CO2, butanes, etc., the polytropic head will trend high toward the surge limit, which is not desirable.

A Sustainable Solution

By using high-purity refrigerants, LNG plants minimize process disruptions and avoid flaring ethane and other lighter components during the HHP stage. These high-purity hydrocarbon refrigerants are:

Zero ODP
Low GWP
Non-toxic
