High-efficiency, portable, and skid-mounted technologies engineered for immediate deployment in European energy distribution networks.
As Germany accelerates its Energiewende (Energy Transition), the metropolitan and industrial zones of Berlin and the surrounding Brandenburg region face unprecedented pressures to decarbonize thermal networks, industrial production, and heavy-duty logistics. Under the local Berlin Climate Protection and Energy Act (EWG Bln), the city-state aims for net-zero carbon emissions by 2040. Achieving this ambitious target requires a multifaceted energy infrastructure strategy that transitions away from coal and heavy fossil fuels toward highly flexible, low-carbon, and zero-carbon alternatives.
Within this framework, Liquefied Natural Gas (LNG), particularly Bio-LNG (liquefied biomethane derived from organic municipal and agricultural waste structures), represents a critical bridging utility. It provides high-density thermal and mechanical power while slashing local particulate matter, sulfur dioxide (SOx), and nitrous oxide (NOx) emissions. Mobile, vehicle-mounted, and skid-mounted LNG installations have emerged as key technological solutions. These modular units bypass the immense financial and regulatory barriers of constructing permanent regional natural gas pipelines, offering rapid deployment to industrial zones, agricultural grid hubs, and off-grid trucking fuel depots.
Globally, the LNG supply chain is shifting from massive, centralized baseload liquefaction terminals toward highly modular, flexible, and decentralized designs. Traditional gas treatment plants demand years of environmental impact assessments and heavy capital expenditure. In contrast, skid-mounted gas treatment systems and pre-assembled cold-boxes are constructed and dynamically tested within a controlled factory environment before being shipped directly to the operating site.
This paradigm shift is driven by three key market forces:
The heart of Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd.'s engineering prowess lies in our proprietary thermodynamic processes. The conversion of gaseous methane to its cryogenic liquid phase (at approximately -162°C under atmospheric pressure) requires highly engineered cooling cycles. Our skid-mounted liquefaction equipment utilizes two primary thermodynamic routes:
The MRC process utilizes a tailored mixture of nitrogen, methane, ethane, propane, and butane. This mixed phase matches the cooling curve of natural gas during liquefaction, minimizing thermodynamic irreversibility. For large-scale localized operations, MRC provides superior energy efficiency, requiring less specific energy (kWh per kg of LNG produced) compared to expansion cycles.
Ideally suited for vehicle-mounted and highly portable systems, this process uses pure gaseous nitrogen as the cooling medium. Because nitrogen is non-flammable and non-toxic, it eliminates complex chemical handling and storage requirements on site. This route is highly valued by German municipal planners seeking approval in environmentally sensitive areas. It features rapid start-stop profiles, allowing operators to react to fluctuating gas feed rates without structural thermodynamic shock to the cold-box heat exchangers.

To ensure reliable, safe operation in the Berlin market, our truck-mounted and skid-mounted LNG systems integrate multi-stage purification protocols. Unprocessed natural gas or biogas contains water, carbon dioxide (CO2), hydrogen sulfide (H2S), heavy hydrocarbons, and trace aromatics. These components must be removed to avoid freezing within the cryogenic micro-channel heat exchangers.
Utilizing a highly efficient MDEA (Methyl Diethanolamine) absorption process, this skid reduces CO2 levels to under 50 ppmv. This step prevents solid dry ice formation inside the cold box, protecting downstream equipment from blockages and pressure buildup.
Using a twin-tower thermal swing adsorption (TSA) system filled with high-grade synthetic zeolites, water content is reduced to below 1 ppmv. The dew point of the gas is brought down to -100°C under pressure, protecting the aluminum plate-fin heat exchangers from hydrate formation.
Before liquefaction, gas passes through a specialized sulfur-impregnated activated carbon bed. This step adsorbs heavy hydrocarbons and mercury, protecting the cold box's brazed aluminum joints from liquid metal embrittlement.
Exporting industrial machinery to Germany requires strict adherence to European manufacturing directives. Hongke Qingneng's design division coordinates closely with inspection bodies (such as TÜV SÜD or TÜV Rheinland) to ensure compliance with the following frameworks:
