Customized Process Gas Engineering, Phase Sizing, Mass Transfer and Thermodynamic Modeling

Our senior chemical and petroleum process engineers perform rigorous thermodynamic, phase equilibrium, fluid dynamics, and mass transfer calculations strictly tailored to your actual wellstream composition (sour H2S, CO2 molar fractions, heavy asphaltenes, paraffin waxes, and formation water salinity), design gas flow rates, operating temperatures, and design pressure conditions. We determine the optimal vessel sizing, internal coalescing matrix, random and structured packing configurations, demisting modules, heating coils, and automated process control instrumentation to ensure maximum separation efficiency and minimum chemical losses across the entire field lifecycle.

Packaged Turnkey Modular Skid Systems, Pre-Commissioned Units and Process Modules

We engineer and deliver turnkey, skid-mounted, factory-tested process packages pre-assembled on heavy structural steel baseframes to drastically reduce on-site civil and construction timelines. Deliverables comprise: ASME Section VIII Div 1 & 2 certified pressure vessels, process interconnecting piping manifolds, automated pneumatic control valves, safety relief valves, glycol-glycol heat exchangers, high-pressure injection pumps, electrical heat tracing, explosion-proof instrumentation junction boxes, and SIL-rated PLC automation panels with emergency shutdown (ESD) capabilities and remote SCADA telemetry integration.

Uncompromised Quality Assurance, ASME/API Conformity, Material Traceability and Factory Acceptance Testing

Every fabricated pressure vessel, piping spool, and heat exchanger undergoes extensive non-destructive testing (100% radiographic inspection of critical weld seams RT, ultrasonic thickness scanning UT, hydrostatic pressure testing up to 1.5x design ratings, and post-weld heat treatment PWHT where specified). Systems are delivered with complete engineering dossiers: certified vessel logbooks, as-built piping and instrumentation diagrams (P&IDs), electrical wiring schematics, finite-element stress calculations, and accredited certificates of conformity adhering to ASME 'U'/'U2'/'R' stamps, API Spec 12J, API Spec 12K, and global pressure vessel directives.
