Modern industrial separation systems represent the operational core of the environmental protection, petrochemical, and cryogenic processing sectors. Historically, gas extraction and pollutant containment required massive, footprint-heavy facilities that struggled to maintain structural integrity under high pressure and thermal swing loads. Today, the demands of the global energy transformation require highly optimized, skid-mounted separation systems designed for rapid deployment, high-purity yield, and absolute thermal efficiency.
As a premier global developer, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. has bridged the gap between theoretical thermodynamics and actual field application. By focusing on multi-phase separation, molecular sieve purification, and low-temperature gas liquefaction, we construct systems that allow operations to capture high-value resources (such as helium, methane, and heavy hydrocarbons) while lowering process emissions to compliant levels.
Our systems exploit the phase-change properties of complex gas mixtures at scale. By using multi-component mixed refrigerants containing nitrogen, methane, ethylene, propane, and isopentane, our custom liquefaction plants systematically drop inlet gas temperatures down to -162°C. At these boundaries, separation occurs based on boiling point differentials. This enables precise BOG (Boil-Off Gas) helium extraction, shale gas purification, and VOC recovery. Our proprietary thermal transfer equations prevent typical flow maldistributions across the tube-and-shell heat exchangers, maintaining operational stability even during fluctuating feedstock flows.
Established in June 2021 with a registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. serves as a modern manufacturing hub in the Sanhe Economic Development Zone, Langfang City. We focus on the research, development, and high-end fabrication of energy conservation and environmental protection equipment.
Our manufacturing catalog includes non-standard A2-level pressure vessels, centralized and mobile medical waste high-temperature steam treatment systems, chemical tail gas treatment modules, VOC extraction skids, and advanced industrial refrigeration systems functioning down to -180°C.
Equipped with state-of-the-art automatic welding stations, non-destructive testing (NDT) rooms, and hydro-testing stations, our facility ensures that every skid-mounted unit matches both Chinese National Standards (GB) and international ASME/CE parameters.

Engineered configurations designed to address challenges across varied industries.
In remote natural gas fields or coal mining zones, untreated gases contain high ratios of CO2, H2S, water vapor, and heavy hydrocarbons. These impurities lead to corrosion and freeze-ups in liquefaction channels. Our purification skids employ a three-stage sequence: amine-based deacidification, solid-desiccant dehydration, and active carbon heavy hydrocarbon filtration. The modular design enables deployment at wellheads, converting flared or vented methane into high-purity LNG.
Modern urban centers and research complexes require secure, high-capacity sterilization for pathogenic bio-wastes. Our automated high-temperature steam treatment systems maintain internal temperatures of 134°C to 138°C at saturated pressures for precise periods. This achieves a verified 6-log (99.9999%) reduction in bacterial spores. We produce both stationary centralized plants for municipal operators and mobile, containerized systems for field hospitals and disaster response units.
Petrochemical processing and manufacturing release high concentrations of Volatile Organic Compounds (VOCs). Conventional incineration destroys these resources. Our systems combine condensative pre-treatment with carbon bed adsorption and thermal swing recovery. By capturing and liquefying VOC solvents at temperatures down to -70°C, we protect surrounding air quality and return reusable raw materials back into the production cycle.
LNG storage tanks lose a small fraction of product through evaporation, creating Boil-Off Gas (BOG). Because helium has a boiling point of -268.9°C (lower than methane), BOG serves as an ideal feedstock for helium extraction. Our cryogenic separation skids process this gas to separate crude helium from methane. This is followed by catalytic deoxygenation and pressure swing adsorption (PSA) cycles to yield 99.999% ultra-pure gaseous helium.
EPC (Engineering, Procurement, and Construction) companies are shifting away from on-site construction toward modular, skid-mounted systems. Building assemblies within controlled factory conditions minimizes weather delays, ensures quality, and reduces field commissioning times.
Modern separation systems require real-time pressure, flow, and temperature tracking. By using PLC architectures with cloud diagnostic integration, operators can monitor separation balances remotely, receive preventative maintenance prompts, and adjust refrigerant volumes automatically based on shifting inlet feeds.
Stricter carbon emission goals are shifting processes away from thermal oxidation (flaring) toward separation systems. These systems capture carbon dioxide directly from tail gas, clean it to food-grade standard, and capture associated hydrocarbons to support zero-flare operations.

Skid-mounting moves up to 90% of structural fabrication, instrumentation, piping, and thermal insulation from the field to our factory. This minimizes field installation costs, ensures high-quality assembly in controlled environments, and speeds up project commissioning. Skids can also be disconnected and relocated if well flow rates shift.
Our single-stage and multi-stage mixed refrigerant refrigeration loops support stable operation from -40°C down to -180°C. For special requirements (such as vacuum cold trap systems), we deliver units operating at -135°C to isolate volatile vapors in laboratories and industrial processes.
Our high-temperature steam treatment systems use a combination of physical parameters (monitored by PLC sensors for pressure and temperature), chemical indicators, and biological indicators (typically Geobacillus stearothermophilus spores). Maintaining saturated steam at 134°C–138°C for the required exposure time guarantees a sterilization level meeting international bio-safety requirements.
Yes. Raw natural gas profiles vary by field. Our engineers use chemical process simulation software to model gas compositions and thermodynamic behavior. Based on the findings, we customize the process, adjusting columns, refrigeration capacity, and dehydration parameters to optimize separation efficiency and prevent downstream hydrocarbon condensation.
