Discover our primary catalog of high-efficiency liquefaction systems, custom treatment plants, and desulphurisation machinery built for global operations.
In modern cryogenic energy infrastructure, the efficiency of liquefaction is highly dependent on heat transfer science. Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. stands at the forefront of this technology, blending advanced engineering with domestic production advantages.
Our core LNG exchangers are designed utilizing highly complex phase-change thermodynamic modeling. This ensures maximum enthalpy exchange in mixed refrigerant systems while keeping energy consumption indicators low.
We minimize on-site installation risks through modular factory fabrication. Each purification and liquefaction unit is assembled on a single structural base, then tested dynamically before shipping.
Before gas enters our cold boxes, high-accuracy pre-treatment systems remove acid gas (CO₂/H₂S), dry moisture down to < 0.1 ppm, and capture heavy hydrocarbons to prevent freezing blocks.
Established in June 2021 with a registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. is positioned in the industrial base of Sanhe Economic Development Zone, Langfang City. The company specializes in the research, design, engineering, and manufacture of advanced environmental protection and energy conservation technologies.
Our extensive product range includes A2-grade pressure vessels, medical waste treatment machinery, chemical exhaust systems, low-temperature industrial refrigeration (-40°C to -180°C), and modular skid-mounted liquefaction equipment for natural gas, shale gas, and coalbed methane.
The core competitiveness of Hebei Hongke Qingneng lies in our scientific leadership, driven by top researchers from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (CAS) and Tsinghua University.
Ph.D. from the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences. National Senior Engineer. Dr. Sun has led key research programs, including the National 863 Program, Aerospace and Military projects, and Chinese Academy of Sciences special research initiatives. Recipient of the Special Prize for Technological Invention from the Chinese Society of Refrigeration (2015) and Beijing Science and Technology Award (2016). Presided over 20+ patents and implemented over 50 sets of skid-mounted LNG systems.
Ph.D. Candidate & Senior Engineer at the Institute of Physics and Chemistry Technology, CAS. He has managed municipal R&D operations and commercial execution for years. Author of 24 international and domestic academic papers (11 indexed in SCI/EI). Holds 5 national invention patents. Awarded the Beijing Science and Technology First Prize (2016) and Silver Medal of the 19th China International Industry Expo.
Doctor of Engineering from the Technical Institute of Physics and Chemistry, CAS. A primary researcher behind the Specially Scaled Skid-Mounted Natural Gas Liquefaction Unit. Dr. Cheng specializes in phase change heat transfer mechanisms, fluid mechanics of multi-component mixed refrigerants (MR), and industrial cold-box structural design. Led the commissioning of several large scale LNG and BOG recovery projects.
Sourcing processing equipment internationally requires managing cost efficiency, compliance standards, and raw material access. Our factory operations leverage Langfang's robust manufacturing hub to address these challenges.
Located in Langfang Economic Development Zone, we have direct access to China's leading metallurgical raw material pipelines. This ensures that all cryogenic stainless steel (e.g., 304L, 316L, 9% Nickel steel) and specialty copper piping meet exact international design codes before manufacturing starts.
We comply with globally recognized standards. Our production plant is certified under GB/T19001-2016 quality management systems, and we maintain strict compliance with Sinopec HSSE and CNPC Health, Safety and Environment Management Systems. Our pressure equipment design qualifies for national A2 standards.
Integrating the engineering design stage with factory fabrication optimizes production schedules. Modular skid assembly reduces field execution costs by up to 40% compared to traditional on-site installation, significantly accelerating project delivery.
Our engineering portfolio spans natural gas liquefaction, custom pressure vessels, tail gas purification, and ultra-low temperature industrial refrigeration.
Quality in cryogenic heat exchange equipment is achieved through precise manufacturing controls. Our workshop integrates welding, assembly, and testing processes to ensure reliable product performance.
Our equipment is deployed in domestic oil fields, chemical recovery plants, and centralized municipal processing centers.
From pre-treatment filtration units to deep cryogenic heat exchangers, each system is fabricated and quality-checked inside our Langfang facility.
Modern natural gas fields are increasingly shifting away from massive, highly centralized liquefaction hubs. Remote gas fields, coalbed methane reservoirs, and stranded shale gas reserves demand flexible, modular solutions. Skid-mounted plants offer swift deployment, reduced permitting cycles, and high capital efficiency for distributed energy grids.
With helium supplies constrained globally, extracting high-value helium from Boil-Off Gas (BOG) in LNG terminals has become a major technical focus. We integrate low-temperature condensation technology with multi-stage membrane filtration to isolate crude helium. Our systems then purify the product to 99.999% liquid helium grade, creating a secondary revenue stream for gas operators.
Industrial facilities must meet strict emissions regulations. Our VOC exhaust treatment units leverage recovery technologies (condensation, adsorption) to recycle organic vapors. This reduces environmental impact and allows operators to reuse chemical solvents, helping facilities meet national and international carbon reduction targets.
Managing hazardous biomedical and experimental animal waste presents logistical and safety challenges. We design high-temperature steam and hydrolysis treatment equipment that achieves complete sterilization on-site. This eliminates the risk of environmental contamination during transit and provides a safe solution for medical systems and laboratories.
