View Plant Specifications →As the United Kingdom accelerates its binding commitment to achieve Net Zero greenhouse gas emissions by 2050, the domestic industrial gas sector is undergoing a profound technological transformation.
Across major British industrial clusters—such as the Humber Estuary, Teesside, Grangemouth in Scotland, and South Wales—cryogenic air separation units (ASUs) have evolved from conventional utility systems into mission-critical enablers of clean energy infrastructure. The UK's aggressive deployment of carbon capture, utilisation, and storage (CCUS) projects and blue hydrogen manufacturing facilities necessitates monumental volumes of high-purity oxygen for autothermal reforming (ATR) and oxy-fuel combustion cycles.
Furthermore, the ongoing modernization of the UK manufacturing base demands decentralized, energy-efficient cryogenic ASU installations that drastically cut power tariffs and eliminate the carbon footprint associated with long-distance road tanker deliveries across British motorways.
Supplying continuous tonnage oxygen to UK autothermal reforming (ATR) hydrogen units and carbon capture oxy-combustion facilities with stringent thermal integration.
Full adherence to British pressure systems safety regulations (PSSR 2000), UKCA marking, BS EN ISO standards, and ASME Section VIII code compliance.
Optimized cold-box thermodynamic cycles combined with high-efficiency multi-stage expanders and compressors deliver industry-leading specific power consumption (kWh/Nm³).
Custom skids for wellhead gas conditioning, acid gas removal, and moisture dehydration compliant with North Sea gas standards.

We are masters of gas extraction, offering a full spectrum of solutions from PSA/VPSA nitrogen and oxygen generators for industrial use to large-scale cryogenic air separation units for high-purity, high-volume production.
We provide reliable power solutions for any scenario, including robust diesel generators for prime or backup power and efficient CNG generators for clean energy applications.
Our expertise extends to the entire gas value chain. We design and build advanced systems for natural gas processing, LNG plants, helium extraction, and carbon capture (CCUS), helping clients optimize resources and meet environmental goals.
For UK manufacturing operations consuming over 500 Nm³/h of gaseous nitrogen or oxygen, installing a dedicated on-site cryogenic ASU drastically reduces cost per cubic metre, insulates against diesel delivery surcharges, and cuts logistics-related scope 3 emissions.
Specific energy consumption (kWh/Nm³ of product gas) is the primary benchmark. Huayan utilizes multi-stream brazed aluminium heat exchangers (BAHX) and dual-column fractional distillation to achieve up to 12% lower electrical power consumption.
All cold boxes, distillation columns, and cryogenic piping skids are engineered and tested in strict accordance with UKCA / CE standards, Pressure Equipment (Safety) Regulations (PER), and ISO 9001 quality management procedures.
Yes. By adding a dedicated argon column with structured packing and crude argon deoxygenation, our plants produce high-purity liquid Argon (purity ≥ 99.999%) required for specialist titanium, aerospace alloy, and nuclear welding in the UK.
