Ten core product series cover the full surface-processing chain of an oil & gas field: separation, heating, pigging, drying, dosing, storage, distribution and column separation — supplied as single vessels or fully integrated skid packages that cut installation time by about 70%.
CGOT’s flagship product family: horizontal and vertical two-phase and three-phase separators, metering separators, cyclone, filter and high-efficiency vane separators, in single-vessel or skid-mounted execution. Processing capacity from 10,000 to 500,000 m³/d, design pressure 0.1–15 MPa, in carbon, stainless or duplex steel.
Learn more →Indirect heating furnaces for wellhead heating, viscous-crude transport and gas dehydration: water-jacket (water-bath) heaters and vacuum phase-change furnaces, as vessels or fully integrated skids. Heat load 50–2,000 kW, pressure 0.1–10 MPa, thermal efficiency ≥85% with flue-gas heat recovery cutting energy use 15–20%.
Learn more →Complete pigging stations for long-distance oil and gas pipelines: launcher skids, receiver skids and combined launcher–receiver packages with quick-opening closures, positioning sensors and automated pressure control — for pre-commissioning gauging and routine wax removal, descaling and in-line inspection.
Learn more →Flue-gas and process-gas SO₂ removal columns using wet limestone, dry/semi-dry and ammonia processes — meeting ultra-low emission standards while turning by-products (gypsum, ammonium sulphate) into usable resources.
Learn more →Twin-tower adsorption dryers for deep dehydration of natural gas and process gases. Molecular-sieve beds alternate between adsorption and thermal/pressure-swing regeneration for continuous dry-gas supply, with regeneration gas recycled to cut energy consumption.
Learn more →Highly integrated skid packages that dissolve and precisely inject solid or liquid chemicals — flocculants, scale and corrosion inhibitors, biocides — into process systems for water treatment, petrochemical, power and environmental duties.
Learn more →Horizontal multifunctional tanks combining storage, buffering and heat exchange — designed for crude recovery and heat-while-producing service. Cylindrical shells with elliptical heads in high-strength carbon or stainless steel, mobile enough to replace fixed civil-works tank farms at well sites.
Learn more →Flameless skid-mounted induction heating for crude, heat-transfer oil and water: electromagnetic induction makes the vessel or pipe itself the heating element — fast, uniform, maintenance-free heating for explosion-rated zones where open flame is not an option.
Learn more →Multi-way valve, piping, instrumentation and control packages on a single steel skid for distribution, metering, pressure regulation and safety control of oil, gas and water streams — the junction box of a producing field.
Learn more →Process columns for petroleum refining, chemical separation and gas purification: distillation, absorption, desorption and extraction towers — including deethanizers, depropanizers and crude oil stabilizers supplied to CNOOC offshore projects.
