Products
Core Product Series
Heating furnaces
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.
Learn more →Pig launchers/receivers
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 →Desulfurization towers
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 →Dryers
Twin-tower adsorption dryers for deep dehydration of natural gas and process gases.
Learn more →Dosing skids
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 →Storage tanks
Horizontal multifunctional tanks combining storage, buffering and heat exchange — designed for crude recovery and heat-while-producing service.
Learn more →EM heating skids
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 →Valve manifold skids
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 →Chemical towers
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.

Applications
Oilfield Production & Gathering
From single-well pads to central gathering stations, CGOT equipment handles crude dehydration, three-phase separation, heating and metering — proven on Shengli, Jianghan and Northwest oilfield projects and in heavy-oil, high water-cut and shale-oil service.
Learn more →Natural Gas Processing
Dehydration, dew-point control, desanding and associated-gas recovery: CGOT builds the separation, drying and heating units that bring raw gas to pipeline and LNG-plant specifications — referenced at Yingkou gas plant, Sujiatun gas field and the Congo (Brazzaville) associated-gas recovery project.
Learn more →Pipeline Infrastructure
For trunk-line operators, CGOT supplies pigging stations and line heaters proven on PipeChina projects — including vacuum heating furnaces for the Jiangsu Binhai LNG feeder pipeline (Binhai–Xuyi) and pig launcher/receiver skids for Shengli Oilfield.
Learn more →Refining, Petrochemical & New Energy
Columns, separators and dosing systems for refineries, chemical plants and emerging clean-energy processes — from crude stabilizers for CNOOC offshore platforms to produced-water stripping towers for CCUS (CO₂ storage) projects at Guangli Oilfield.
