The processing of natural gas involves critical purification steps that yield environmental emissions if unmanaged. Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. (established in June 2021, Registered Capital: 78 Million Yuan) stands at the forefront of industrial gas purification, cryogenic recovery, and environmental safety engineering. From our state-of-the-art engineering base in Sanhe Economic Development Zone, Langfang City, we design and fabricate high-integrity processes for global operators.
Underpinned by direct research contributions from academic centers like Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (CAS), we manufacture critical assets including A2-level pressure vessels, skid-mounted natural gas/shale gas/CBM purification packages, boil-off gas (BOG) tail gas helium extraction facilities, and hazardous biological waste treatment systems. Our focus is ensuring zero-leakage, high-recovery performance that transforms environmental compliance costs into productive resource cycles.
Real industrial authority stems from proven scientific foundations. Our engineering breakthroughs are directed by leading cryogenic physicists and materials engineers from China's top academic and state-level laboratories.
Dr. Sun holds a PhD from the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS), and holds the title of National Senior Engineer. He has served as principal investigator for the National 863 Program, the Natural Science Foundation of China, aerospace defense systems, and major scientific special projects of the CAS. His research has earned the Excellent Young Paper Award (Engineering Thermodynamics, 2007), the First Prize of Science and Technology of the China Coal Industry (2013), the Special Prize of Technological Invention of the Chinese Society of Refrigeration (2015), and the First Prize of the Beijing Science and Technology Award (2016). He has guided the deployment of over 50 small skid-mounted LNG/recovery packages.
Dr. Zou is a Senior Engineer and PhD candidate from the Institute of Physics and Chemistry Technology, CAS. For over a decade, he has directed the market-facing deployment of environmental engineering processes. His publications cover 24 peer-reviewed academic papers (including 11 SCI/EI papers), and he holds 5 national invention patents. Dr. Zou was co-awarded the Special Award of the 7th China Refrigeration Society Technological Invention Award (2015) and the Silver Medal of the 19th China International Industry Expo (2017).
Dr. Cheng received his Doctor of Engineering from the CAS Institute of Physics and Chemistry Technology. A pioneer in low-temperature thermodynamic systems, he developed the "Specification Series Skid-Mounted Natural Gas Liquefaction Technology." His basic research focuses on phase change heat transfer characteristics and multi-component mixed refrigerant flow profiles. His findings directly inform our tail gas recovery thermal designs, enabling optimal thermal sizing and thermodynamic efficiency.
Modern natural gas sweetening plants generate tail gas streams laden with sour gases ($H_2S$, $CO_2$), volatile organic compounds (VOCs), BOG fractions, and trace noble gases. Traditional combustion or venting of these slip streams is no longer permissible under tightening EPA, EU, and national regulations. Industrial operators require process pathways to minimize carbon intensity while recovering valuable co-products.
Traditional Claus units achieve 95% to 98% sulfur recovery. The residual gas contains $H_2S$, $SO_2$, $CS_2$, and $COS$. Our advanced hydrogenation and amine recovery packages convert all sulfur compounds back to $H_2S$ before re-routing them to the primary amine treatment column, achieving total sulfur recovery efficiencies exceeding 99.9%.
BOG (Boil-Off Gas) from LNG storage tanks represents a high-purity hydrocarbon stream rich in nitrogen and helium. Utilizing multi-stage cryogenic separation columns and non-condensable fraction fractionation, we extract high-purity industrial helium (He) alongside clean fuel gas, securing a high-value byproduct.
For low-to-medium flow rates, we provide skid-mounted dry desulfurization (using engineered iron oxide or activated carbon beds) and regenerative wet desulfurization systems. These systems guarantee $H_2S$ concentrations below $4 \text{ mg/Nm}^3$ to prevent corrosion and satisfy environmental regulations.
Civil work at remote extraction assets is costly and logistically challenging. To mitigate field installation hazards and project delays, Hebei Hongke Qingneng specializes in skid-mounted process engineering. Our gas recovery, purification, and liquefaction units are designed, assembled, wired, piped, and fully wet-tested in our controlled Langfang workshop before transport.
Raw natural gas must undergo rigorous pre-treatment before liquefaction or transport. Our skid-mounted packages cover:
Complementing our gas recovery solutions, we manufacture pressure vessel solutions for bio-safety containment. Our central and mobile high-temperature steam sterilization systems handle laboratory animal carcasses and medical waste. Incorporating advanced thermal-hydrolysis technology, they safely break down biological waste, rendering it sterile and inert.
Our systems are engineered for diverse environments, ranging from isolated shale blocks to municipal clinical containment sites.
High-pressure thermal decomposition system engineered for biological research facilities requiring biosafety level compliance.
Trailer-mounted high-temperature steam sterilization system, enabling decentralized medical waste mitigation.
Compact liquefaction system capturing associated gas, converting flare gas into marketable LNG.
Automated steam autoclaving plant designed for municipal-scale biomedical waste processing.
Procuring pressurized industrial gas processing equipment requires strict adherence to regional safety and quality regulations. Hebei Hongke Qingneng maintains design and fabrication qualifications to support global deployment:
Authorized to fabricate medium-to-high pressure vessels. Our products undergo full radiographic testing (RT), ultrasonic testing (UT), and hydro-testing to meet rigorous safety specifications.
We maintain certifications for major national oil companies, including Sinopec HSSE and China Petroleum Health, Safety and Environment Management System (CNPC HSE).
Our operations are certified under the GB/T19001-2016 / ISO9001:2015 standard, guaranteeing material traceability, welding procedures (WPS), and systematic quality audits.
As the global energy transition accelerates, natural gas processing must adapt to tighter environmental regulations. Hebei Hongke Qingneng is actively developing technologies to support these changes:
Commercial helium extraction typically requires feed gas concentrations above 0.1%. Our research team is designing cryogenic fractionation schemes capable of processing feed streams with helium content down to 0.03% to 0.05%, broadening the economic viability of helium recovery.
Drawing on the work of Dr. Sun Zhaohu and Dr. Cheng Kuwei, we optimize mixed refrigerant composition ratios (combining nitrogen, methane, ethylene, propane, and isopentane) to match the cooling curves of target gas streams, reducing compressor energy consumption by up to 15%.
