Our Work
Modular Packages Units Supply Service
Two-Stage Dehydrator-Desalting Unit
Upstream & Downstream

Two-Stage Electrostatic Dehydrator and Desalting Unit

An advanced processing system engineered for the highly efficient removal of salt, basic sediment, and emulsified water from raw crude oil streams. Operating through a rigorous two-stage electrostatic separation loop, this critical infrastructure drastically minimizes fouling, scaling, and corrosive wear on downstream processing equipment. It ensures delivered crude fully conforms to strict international pipeline and refinery sales specifications.

H2S Removal Plant
Upstream & Midstream

Hydrogen Sulfide Removal and Gas Sweetening Plant

A specialized desulfurization and gas-sweetening facility engineered to safely extract toxic and highly corrosive hydrogen sulfide from sour crude oil and associated natural gas streams. By neutralizing acid gas hazards directly at the source, this process safeguards critical transportation infrastructure against sulfide stress cracking, guarantees strict operational safety across all fields, and meets environmental emissions compliance.

Process Skid
All Sectors

Modular Integrated Process Skid Package

A turnkey, custom-engineered modular solution pre-assembled, piped, wired, and rigorously tested under factory-controlled conditions before deployment. These self-contained units integrate mechanical equipment, fluid piping, structural steel frames, instrumentation, and standalone control elements, providing rapid, seamless site installation with drastically reduced local construction timelines and downtime.

FOTP Process Skid
Downstream & Upstream

Fuel Oil Treatment Plant Process Skid System

An engineered process skid optimized for the intensive conditioning, heating, filtration, and regulation of heavy fuel oils and crude fuel streams. The module precisely manages fluid viscosity, density, and purity, ensuring a continuously stable, clean, and optimized fuel supply line directly to industrial gas turbines, steam-generation boilers, and heavy maritime propulsion systems.

Desalting Unit
Downstream

Crude Oil Electrostatic Desalting Unit

A high-capacity desalting system utilizing powerful electrostatic fields to break down water-in-oil emulsions and wash out dissolved water-soluble chlorides from incoming crude oil. Strategically situated as the very first processing stage inside modern refineries, it effectively halts hydrochloric acid formation during distillation, protecting overhead systems, furnaces, and downstream catalysts from premature degradation.

EWTP
Downstream & Midstream

Effluent Water Treatment Plant

A highly sophisticated, multi-stage facility engineered to treat, purify, and recycle complex industrial wastewater and plant runoff streams. Combining chemical, physical, and biological separation technologies, this package removes hydrocarbons, toxic heavy metals, and operational chemicals, enabling safe environmental discharge or industrial water reuse in complete alignment with global ecological protocols.
