LNG plant filtration, engineered at the train.

Four separation duties decide whether an LNG train runs clean.
ITSB delivers LNG plant filtration in Malaysia on genuine Pentair Oil & Gas Separations technology — inlet gas separation, amine solvent filtration, dry gas filtration and fuel-gas conditioning.

The four filtration duties of an LNG plant

Inlet gas separation

Sub-micron liquid aerosols from the pipeline — compressor lube oils, corrosion inhibitors, condensate — foul everything downstream. UltiSep separators with Apex Zenith elements remove them at the fence.S1 Inlet gas separation →

Amine solvent filtration

Contaminated amine foams, derates the AGRU and threatens the SRU. Coreless MPAX / COMPAX elements keep the solvent loop clean at the root.S1 Amine systems →

Dry gas filtration

Solids and carryover ahead of cryogenic exchangers and molecular sieves — where a fouled pass costs train capacity. InterSep dry gas filtration applies.S1

Fuel-gas conditioning

Dry low-NOx turbine combustors are unforgiving on liquids. UltiSep fuel-gas conditioning protects the machines that power the train.S1

Engineered and supported from Malaysia

Malaysia liquefies gas at one of the largest LNG complexes on earth, and the plants that feed it run the same separation duties listed above. ITSB has engineered separation and filtration across Malaysian gas processing for 30 years — design, genuine Pentair elements, vessels and commissioning, delivered and supported in-region rather than shipped from another continent.

Engineer questions

Asked before the enquiry

What does LNG plant filtration cover?
LNG plant filtration covers four duties: inlet gas separation at the plant fence, amine solvent filtration in the acid gas removal unit, dry gas filtration ahead of cryogenic equipment, and fuel-gas conditioning for the plant’s turbines. Pentair Oil & Gas Separations supplies technology for all four, delivered in Malaysia by ITSB.
Why do conventional inlet separators fall short on LNG duty?
Conventional gas-liquid separators are approximately 20–40% effective at removing liquid aerosols and cannot capture the most penetrating sub-micron droplets . At LNG train flow rates, the remainder carries into amine systems, exchangers and turbines as fouling and foaming.
Which Pentair element is current for LNG inlet separation?
Apex Zenith is the current flagship element for gas/liquid separation, rated above 99.99% efficiency on 0.1 micron aerosols with 50% higher velocity and loading capability than the prior generation . It runs inside UltiSep separators.
Can an existing inlet separator be upgraded without replacing the vessel?
Yes. Pentair’s NexSys vessel re-engineering upgrades existing separators — including competitor vessels — to current Apex Zenith internals without welding or permanently altering the vessel . ITSB has been putting these upgrades into this market for 30 years.
Who supports Pentair LNG filtration in Malaysia?
ITSB — the authorized Pentair Oil & Gas Separations agent for Malaysia & Asia-Pacific — engineers, supplies and commissions LNG-duty filtration locally, with genuine Pentair replacement elements backed in-region.
