In the process gas transportation and compression links of industries such as petrochemicals, chemicals, and new energy, the stability, energy efficiency ratio, and compatibility of equipment directly affect production efficiency and operating costs. The LYLG type process gas twin-screw compressor system, with its precise structural design and advanced control technology, has become the preferred equipment for process gas treatment in the industrial field, providing reliable support for gas compression under complex working conditions. The core advantage of this system stems from the optimized design of the twin-screw rotor. The 5:6 asymmetric toothed rotor is adopted, combined with high-precision grinding processing technology, ensuring that the rotor meshing clearance is controlled within 0.02mm. This not only enhances the gas compression efficiency but also reduces the operating noise. The overall operating noise of the machine is below 85dB (A). According to the physical properties of different process gases, the system can be customized with corrosion-resistant and high-temperature resistant rotor materials, compatible with various media such as hydrogen, natural gas, and carbon dioxide. The working temperature can reach 200℃, and the exhaust pressure covers 0.3-1.6MPa, meeting the production needs of multiple scenarios. Intelligent control and effective energy conservation are another major highlight of it. Equipped with a PLC intelligent control system, it can achieve real-time monitoring and automatic adjustment of exhaust pressure, temperature and flow rate, with a response speed as fast as 0.1 seconds, ensuring the stability of process parameters. By adopting variable frequency speed regulation technology, the operating speed is dynamically adjusted according to the gas demand. Compared with traditional fixed-frequency compressors, it saves 15% to 30% of energy. Meanwhile, it integrates a highly efficient oil-gas separation device with a separation efficiency as high as 99.9%, effectively reducing the oil content in the gas and ensuring the purity requirements of subsequent processes. In practical applications, the LYLG type system demonstrates extremely strong adaptability and reliability. In the natural gas transmission link of the petrochemical industry, its high-pressure resistance and corrosion resistance characteristics ensure long-term stable operation. In the synthesis gas compression process of the chemical industry, precise flow control helps to enhance reaction efficiency. In New
