Give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the dual-medium coaxial hydraulic turbine generator set, designed and manufactured by the Beijing Aerospace Power Research Institute under the Sixth Academy of the China Aerospace Science and Technology Corporation, has completed all necessary tests and is ready to be sent to the customer’s construction site. This turbine utilizes a completely new radial-flow turbine design theory, and boasts technical advantages such as high pressure drop per stage, fewer stages, strong rotor stability, and high efficiency; it enables the achievement of the goal of using two streams of fluid to drive a single power generation unit. The low-temperature methanol washing process uses methanol as an absorbent to remove impurities such as H2S, CO2, and various organic sulfur compounds from the raw gas produced in the later stages of coal gasification, under high pressure and low temperature. The methanol enriched with these impurities and pollutants is then subjected to depressurization, stripping, and heating processes to be regenerated and reused. In recent years, whether for new installations or the retrofitting of existing ones, the use of hydraulic turbines operating with sulfur-containing or sulfur-free methanol media in pressure reduction sections has become a necessary option for energy savings. Dual-media coaxial hydraulic turbine generator sets have even emerged as new products in this field. **“The 14th Five-Year Plan places strong emphasis on energy-saving upgrades and advanced pollution control in industries such as steel, non-ferrous metals, building materials, and petrochemicals. The goal is to reduce energy consumption per unit of GDP across the country by 13.5% by 2025, while also keeping the total amount of energy consumed under reasonable control. As an energy-saving device that operates in parallel with high-pressure relief valves in industrial installations, the hydraulic turbine has a relatively broad market potential. In recent years, the Fluids and Rotating Machinery Division of the Beijing Aerospace Power Research Institute has intensified its efforts in product development. It has created the world’s first high-speed hydraulic turbines, as well as MW-class multi-stage hydraulic turbines and other related products, covering all existing structural requirements and parameter needs for hydraulic turbines and thus establishing a relatively comprehensive product planning system. During the same period, the development of a 2100kW high-speed multi-stage pump was also completed, providing solutions for fluid transfer and energy savings under harsh conditions such as high pressure, high temperature, high speed, and large flow rates.
