Established in June 2021 with a substantial registered capital of 78 million Yuan, Hebei Hongke Qingneng has rapidly ascended as a prominent force in the engineering, design, and manufacturing of advanced energy recovery and environmental protection equipment. Situated within the Sanhe Economic Development Zone of Langfang City, our state-of-the-art facility occupies a pivotal geographical location near major manufacturing clusters, ensuring unmatched logistical efficiency and supply chain integration.
We specialize in providing one-stop, turnkey solutions for skid-mounted natural gas purification and liquefaction, non-standard A2 pressure vessels, biological waste treatment, and high-performance industrial refrigeration units. Through structured collaboration with leading academic institutions, we solve the engineering complexities of cryogenic separation, sour gas sweetening, and flare gas monetization.
Under the visionary guidelines of Saudi Vision 2030, the Kingdom of Saudi Arabia is aggressively shifting its domestic energy matrix away from liquid fuels toward natural gas and clean renewables. By expanding its Master Gas System (MGS) and unlocking massive unconventional gas plays such as the Jafurah Basin, Saudi Arabia aims to utilize natural gas for cleaner domestic power generation and petrochemical feedstock, freeing up precious oil for export.
However, the Kingdom's geographical vastness and remote geological basins pose significant infrastructure challenges. Remote wells, associated petroleum gas (APG) from remote gas-oil separation plants (GOSPs), and stranded unconventional reserves cannot always be economically connected to centralized pipeline networks. This is where truck-mounted and skid-mounted liquefied natural gas (LNG) plants emerge as a vital technology.
Saudi Aramco's strict environmental standards mandate zero routine flaring. Skid-mounted recovery systems convert waste flare gas directly into transportable LNG at the wellhead.
Modular liquefaction units allow rapid testing and early production systems (EPS) in exploration zones like the Rub' al Khali without long pipeline construction times.
Truck-mounted LNG plants liquefy natural gas at local wells, enabling standard cryogenic tanker trucks to distribute fuel directly to heavy industries and remote power hubs.
Standard gas processing cannot simply be scaled down for mobile applications. High temperatures (frequently exceeding 50°C in Saudi oilfields), sour gas composition, and varying hydrocarbon fractions require sophisticated thermodynamic engineering.
Unlike simple nitrogen expansion systems that suffer from low thermodynamic efficiency, our skid-mounted LNG systems utilize a closed-loop Mixed Refrigerant Cycle (MRC). Our chief engineers customize the refrigerant composition (comprising nitrogen, methane, ethane, propane, and butane) based on the local feed gas pressure and composition. This yields up to a 30% reduction in specific power consumption (kWh per kg of LNG produced).
Before natural gas enters the cryogenic main heat exchanger (-162°C), it must be thoroughly purified to prevent freezing and corrosion:
Designing cryogenic heat exchangers for desert conditions requires advanced heat rejection systems. Our plants utilize oversized air-fin coolers with variable-frequency drive (VFD) fans designed to handle peak ambient temperatures of 55°C without triggering high-pressure shutdowns.
Our systems include options for integrated extraction of helium from Boil-Off Gas (BOG). In the Middle East, where helium concentration in natural gas reserves is economically viable, this module extracts high-purity crude helium, providing an additional high-value revenue stream.
Our core advantage lies in the direct translation of academic research from China’s elite thermodynamic laboratories into practical, field-proven industrial solutions.

Mobile truck-mounted systems allow immediate deployment to remote Gas-Oil Separation Plants where gas flaring presents environmental liabilities. Easily relocated once local reservoir kinetics drop.
Supplying modular clean energy generation packages to provide immediate virtual-pipeline LNG fuel to off-grid development zones, powering construction machinery and local micro-grids.
Understanding the core operational trade-offs helps engineering procurement managers choose the optimal layout for wellhead recovery.
Direct answers to technical queries raised by process engineering consultancies, project leads, and procurement teams.
Our skid-mounted process designs are explicitly rated for 55°C peak ambient temperatures. We utilize oversized air-fin heat exchangers with high air-flow rates, and design our Mixed Refrigerant Cycle (MRC) compressors with larger thermal reserve margins. Instrumentation and electrical enclosures are dual-shielded, air-conditioned, and certified to meet high-ambient HCIS parameters.
Yes. Before cryogenic liquefaction, feed gas passes through our integrated deacidification skid. We construct our sour gas sweetening contactors using SS316L and Duplex stainless steel to resist stress-corrosion cracking (SCC) caused by high concentration of hydrogen sulfide (H₂S) and carbon dioxide (CO₂).
A standard 100,000 Nm³/day plant is split into three main modules: raw gas pretreatment, cryogenic liquefaction, and refrigerant compressor. Each module measures approximately 12m x 2.4m (standard container footprint) and sits directly on a level, reinforced concrete slab. Structural anchoring is designed for high seismic and wind loads common in the region.
Yes, our skid-mounted configurations come with a dedicated BOG re-liquefaction compressor or a return-to-fuel line. This ensures zero hydrocarbons are vented or flared during storage and tanker loading procedures.
