Advanced structural engineering, strict compliance with ASME, and modular skid-mounted architectures.
Founded in June 2021 with a substantial registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. is a leading-edge technology developer and industrial manufacturer. Located in the highly strategic Sanhe Economic Development Zone, Langfang City, we have built a world-class manufacturing center dedicated to energy conservation, carbon reduction, and heavy industrial environmental engineering.
Our core capabilities range from designing and manufacturing certified ASME/GB Class A2 pressure vessels to producing comprehensive, skid-mounted natural gas purification & liquefaction plants, VOC emission abatement hardware, centralized high-temperature medical waste sterilization systems, and cryogenic cold-traps reaching temperatures down to -185°C.
Guided by our operational principle—"Innovation-driven development, service-led upgrading"—we combine theoretical physics, cryogenic engineering, and industrial chemistry to offer EPC contractors and global energy companies seamless, turn-key solutions.
Our competitive advantage lies in our deep engineering pedigree. By bridging the gap between national laboratory research and industrial field execution, we transform complex thermal equations into robust, field-tested systems.

He developed the "Skid-mounted LNG unit with series specifications," winning the 2016 Beijing Science and Technology Award. He manages the thermodynamic layout of all gas liquefaction processes.
Industrial gas processing demands absolute structural integrity. We manage risk through strict regulatory compliance and robust design verifications.
Authorized to manufacture high-pressure vessels (Class III). Every weld seam undergoes 100% non-destructive testing (RT/UT/MT/PT) with state-of-the-art radiographic imaging, ensuring safety at high pressures.
Our quality management and execution methodologies align with the strict standards of CNPC and Sinopec Health, Safety, Security, and Environment (HSSE) management protocols for high-hazard oil and gas projects.
From the raw steel procurement stage through chemical analysis, stress relieving, heat treatment, pressure testing, and final surface treatment, our ISO 9001 integrated quality system records complete digital traceability.
The global gas pressure vessel market is undergoing a transition driven by carbon neutrality mandates, the expansion of natural gas as a transition fuel, and the rise of the green hydrogen economy. Heavy industrial clients, refinery operators, and EPC firms now face strict operational demands:
Modern pressure vessels must handle extreme temperatures (down to cryogenic levels of liquefied natural gas and liquid nitrogen) and manage hydrogen embrittlement. This requires high-alloy austenitic stainless steels and advanced cladding techniques.
Procuring raw tanks is no longer sufficient. EPCs demand fully integrated, skid-mounted platforms that include the vessel, instruments, valve manifolds, control systems, and safety interlocks. This minimizes on-site commissioning time.
Refineries require zero-emission targets, which increases demand for advanced VOC thermal oxidizers, tail gas purification systems, and Helium (He) extraction loops from natural gas BOG streams.
Our factory utilizes advanced metallurgy and robotic plasma welding to construct pressure vessels with minimal heat-affected zones. Through our research partnerships, we simulate fluid dynamics (CFD) and thermodynamic stresses to optimize flow distribution inside our heat exchangers and pressure systems. This extends service life, lowers structural weight, and reduces total lifecycle costs for procurement managers.
Our technical capabilities span four primary industrial sectors, providing reliable performance in demanding environments.
Complete skid-mounted assemblies for natural gas, coalbed methane (CBM), and shale gas. Our purification lines utilize advanced deacidification, dehydration, and heavy hydrocarbon removal systems, paired with compact mixed refrigerant cycle (MRC) liquefaction blocks.
High-efficiency desulphurisation plants, multi-stage VOC purification reactors, and chemical tail-gas scrubbers. Our systems help industrial facilities meet strict air quality standards and capture valuable hydrocarbons.
Mobile and centralized high-temperature steam treatment systems for hazardous medical waste. We also design thermal hydrolysis equipment for laboratory animal carcasses, utilizing high pressure and heat to ensure biosecurity.
Industrial refrigeration units operating between -40°C and -180°C, high-performance freeze dryers (-70°C to -100°C), vacuum cold traps (-135°C), and BOG tail gas helium extraction units designed to capture valuable trace elements.
Proven project delivery across diverse geographical environments and process conditions.
Designed for biosecurity facilities, utilizing high-pressure thermal hydrolysis to process organic materials safely.
A self-powered mobile containment vessel configured for remote medical facilities and emergency response deployment.
Monitored skid layout capturing flared natural gas, turning waste into liquefied energy.
Large-scale, multi-autoclave facility featuring automated loader systems and integrated off-gas treatment.
As industrial facilities work to reduce carbon emissions, the role of pressure vessels has changed. Modern systems are designed to operate as active thermal thermodynamic units. Our R&D department continues to develop technologies that address these needs:
Helium is a critical global resource for semiconductors and MRIs. It remains gaseous at temperatures where methane liquefies. We design dual-stage cryogenic distillation units that extract crude helium from natural gas boil-off gases, helping operators capture high-value gaseous assets.
Removing acid gases like CO2 and H2S requires efficient mass transfer. We optimize the physical geometry of our column internals and pressure vessels to improve absorption efficiency, reducing energy consumption during the solvent regeneration phase.
Traditional cascades require multiple compressors. Our single-compressor mixed refrigerant cycle systems use a optimized blend of hydrocarbons and nitrogen. This design provides reliable thermodynamic performance in a compact footprint suitable for small and medium-scale gas fields.
