#### Core Products and Solutions

Sichuan Hengzhong Clean Energy specializes in providing a wide range of advanced equipment and turnkey solutions designed to optimize various stages of natural gas processing and utilization. Its core product lines include:

**1. Wellhead Treatment Equipment:**
Natural gas extraction from underground reservoirs involves raw gas rich with impurities and liquid hydrocarbons that must be separated and treated before further processing or transport. Hengzhong’s wellhead treatment packages are engineered to handle complex well conditions, offering efficient gas-liquid separation, removal of contaminants such as water, sand, and other particles, and stabilization of gas flow. These systems enhance production safety and improve downstream process performance.

**2. Natural Gas Conditioning Equipment:**
To meet pipeline quality standards and customer specifications, raw gas must undergo conditioning to remove undesirable components such as carbon dioxide (CO₂), hydrogen sulfide (H₂S), water vapor, and other impurities. Hengzhong’s natural gas conditioning units utilize proven technologies like absorption, membrane separation, and adsorption, delivering purified natural gas with optimal calorific value and moisture content. These customized solutions ensure compliance with regulatory requirements while maximizing energy efficiency.

**3. Light Hydrocarbon Recovery Unit:**
During natural gas processing, valuable light hydrocarbons—such as propane, butane, and pentane—need to be recovered both for sale as separate products and for reducing vapor pressure in gas streams. Hengzhong’s light hydrocarbon recovery units (LHRUs) employ advanced cryogenic and refrigeration cycle techniques to capture these components effectively, maximizing hydrocarbon value and supporting the circular economy. The company’s proprietary designs minimize operational costs and environmental footprint.

**4. LNG Liquefaction Plant:**
Liquefied Natural Gas (LNG) is essential for transporting natural gas over long distances where pipelines are impractical. Hengzhong designs and manufactures complete LNG liquefaction plants that convert natural gas into its liquid form by cooling it to approximately -162°C. The company’s LNG solutions are modular, scalable, and incorporate cutting-edge turbo-expander and mixed refrigerant technologies to ensure high liquefaction efficiency, safety, and operational reliability. These plants also support small to mid-scale LNG projects, aiding in the global expansion of cleaner energy alternatives.

**5. Hydrogen Production Unit:**
As the world shifts towards low-carbon energy systems, hydrogen is gaining prominence as a clean fuel and industrial feedstock. Hengzhong has extended its expertise to hydrogen production technologies, developing units capable of generating high-purity hydrogen through processes such as steam methane reforming (SMR) integrated with carbon capture or electrolysis powered by renewable electricity. These units support clients’ transitions to sustainable energy vectors and comply with stringent environmental norms.

**6. Gas Generator Sets:**
To cater to the growing demand for distributed power generation using natural gas and other clean fuels, Hengzhong provides reliable gas generator sets. These sets are engineered for superior performance, fuel flexibility, and low emissions, suitable for industrial, commercial, and remote applications. Incorporating advanced control and monitoring systems, the generator sets facilitate efficient onsite power production while minimizing carbon footprint.
