TSA (Temperature Swing Adsorption) regenerates adsorbents through cyclic heating and cooling, particularly suited for deep dehydration of industrial gases (dew point down to below −60°C) and polish removal of trace impurities (SO₂, Hg, BTEX, etc.). It is a standard process step in high-purity gas refinin...

Trace O₂, H₂, CO, or VOC residues in industrial gases cannot be reduced to sub-ppm levels by conventional adsorption. We employ precious metal or transition metal catalysts to convert these impurities into harmless products (H₂O, CO₂) via catalytic oxidation or hydrogenation, achieving deep gas purification.

PSA (Pressure Swing Adsorption) separates gas components based on differential adsorption affinities on adsorbent materials through cyclic pressurization and depressurization. Widely used for hydrogen, nitrogen, and oxygen production as well as valuable component recovery from industrial off-gas, it is one of the ...

Upgraded biomethane (CH₄ > 96%) can be further processed into CBG (compressed biogas, 20 MPaG) or bio-LNG (−162°C), while CO₂ by-product from upgrading is liquefied for sale as liquid CO₂, enabling full-stream resource utilization.

Pretreated biogas enters the CO₂ removal system where CH₄ content is upgraded from 50-70% to 96-99%+ to meet CBG vehicle fuel standard (GB 20711) or natural gas pipeline injection standard (GB 17820). We offer both wet aMDEA and dry PSA technology routes with matching drying solutions.

Biogas treatment engineering uses organic waste (livestock manure, food waste, sludge) as feedstock, produces biogas through anaerobic digestion, and purifies it into clean energy products such as compressed biogas (CBG) or bio-LNG. We undertake turnkey engineering from biogas pretreatment to final product formati...

Deeply purified and dried natural gas (CH₄ > 98%) is liquefied at −162°C into LNG, reducing volume by approximately 625x for efficient storage and long-distance transport. We provide integrated services from liquefaction process design to critical equipment supply.

H₂S and CO₂ in natural gas are acidic gases that corrode pipelines and equipment while reducing the calorific value. We provide proven acid gas removal solutions including MDEA chemical absorption and physical solvent processes based on acid gas content and downstream specifications, ensuring stable gas quality co...

Natural gas contains saturated water vapor, which can form hydrates and cause pipeline blockages during transport. We select triethylene glycol (TEG) absorption or molecular sieve TSA for deep drying to lower the dew point to meet pipeline or liquefaction specifications.

CO₂ produced during natural gas acid gas removal should not be vented. We compress, dry, and liquefy it to produce industrial or food-grade liquid CO₂ (LCO₂), or inject it at elevated pressure into oil reservoirs for enhanced oil recovery (CO₂-EOR), enabling resource utilization.

Filtration and metering is critical for custody transfer and data traceability. The separated gas phase undergoes multi-stage filtration and precision metering, combined with condensate stabilization, to minimize natural gas losses.

Three-phase separators serve as the first processing unit in surface production systems, separating wellhead gas-liquid-water mixtures into natural gas, condensate, and produced water via gravity settling, providing clean feed for downstream units. Equipment is delivered in skid-mounted packages suited to diverse ...
