Industry & Application

CNG Filling Station

High-pressure natural gas compression for vehicle refueling (up to 250 bar); delivers reliable, pulsation-free boosting for fast-fill and time-fill dispensers, with integrated cascade storage control and safety systems for continuous retail or fleet-service operation.

Gas Wellhead

Wellhead gas boosting and flowline pressure management; provides robust compression to overcome declining reservoir pressure, lift associated gas, and stabilize production rates, with wide turndown capability to handle fluctuating wellhead conditions and liquid carryover.

Gas Processing Plant

Feed-gas compression for amine sweetening, glycol dehydration, and NGL fractionation; ensures efficient, continuous boosting for acid-gas removal, hydrocarbon dew-point control, and mercury filtration, delivering treated residue gas that meets strict pipeline-quality or downstream petrochemical feedstock specifications.

Gas Gathering Station

Multi-well aggregation and trunk-line boosting; integrates high-volume centrifugal or reciprocating compressors to collect low-pressure wellhead gas, overcome pipeline friction losses over long distances, and maintain optimal suction pressure for central processing facilities, with automated flow allocation and slug-handling features.

Gas-Fired Power Plant

Fuel-gas compression for gas turbines and combined-cycle HRSG systems; delivers high-pressure, clean, superheated natural gas to combustion chambers with precise pressure regulation and rapid load-following response, supporting base-load generation, peak-shaving, and low-NOx emission targets.

Gas Storage

Underground Gas Storage

Injection and withdrawal compression for salt-cavern or depleted-reservoir storage; handles large-volume bi-directional gas cycling with high-ratio pressure boosting, enabling seasonal peak-shaving, emergency supply, and grid-balancing duty, with robust design for frequent start/stop and variable suction conditions.

Offshore Platform

Compact, corrosion-resistant gas compression for platform utility, lift-gas reinjection, and sales-gas export; delivers reliable, space-efficient boosting in harsh marine environments, with modular topside packaging, dry-gas seals, and remote condition monitoring to ensure uninterrupted service in explosive-classified zones.

LNG Liquefaction Plant

Multi-stage mixed-refrigerant (MR) and boil-off gas (BOG) compression for the liquefaction train; provides high-efficiency, oil-free centrifugal or integrally-geared compression for pre-cooling, main cryogenic, and sub-cooling cycles, ensuring 24/7 continuous operation with minimal fouling, plus BOG re-liquefaction for storage and loading terminal stability.

After-Sales Service Capability

After-sales Service Personnel Own authorized service engineers trained by ARIEL, DRESSER RAND, COOPER for compressors and CATERPILLAR, WAUKESHA for engines.

Electrical Engineers CompEx certified, and qualified to work in explosion protection areas.
