Jiujiang Xinlianxin Fertilizer successfully commissioned a generator set that utilizes the residual pressure from CO2 waste gas generated during low-temperature methanol washing processes. Author/Source: Tianjin Petrochemical News. Date: November 9, 2022. Clicks: 18. Recently, China’s first generator set of its kind, capable of utilizing the residual pressure from CO2 waste gas produced in low-temperature methanol washing processes, was successfully put into operation at Jiujiang Xinlianxin Fertilizer Co., Ltd., enabling power generation; this adds another tool to the efforts aimed at energy conservation and emission reduction. It is understood that this unit utilizes the high-speed radial flow turbine technology independently developed by Tianjin Kuaituipai Technology Development Co., Ltd. (hereinafter referred to as “Kuaituipai Technology”). This technology fills a gap in China’s technological landscape and is at the international leading level; it has been included by the Tianjin Development and Reform Commission in Tianjin’s list of green technologies to be promoted. Low-temperature methanol washing is a commonly used carbon and sulfur removal process in the coal-to-gas chemical industry. The CO2 exhaust gas produced has different pressures, and when released into the atmosphere, the pressure energy contained in this exhaust gas is wasted. By using residual pressure generator sets to recover the pressure energy in CO2 exhaust gases, the wasted residual pressure from the exhaust gases can be converted into electricity. This not only enhances the economic efficiency of factories but also brings social benefits in terms of energy conservation and emission reduction. Once operational, this power unit will generate 5.42 million kWh of clean electricity per year, yielding an income of 3.58 million yuan. It will also result in a yearly savings of 2,189 tons of standard coal, as well as a reduction of 5,457 tons of carbon dioxide emissions per year. Furthermore, after passing through the excess pressure generator set, the temperature of the CO2 exhaust gas is reduced by about 40°C, and 510 kW of cooling energy can be recovered for cooling the plant’s low-temperature circulating water. Established in the Tianjin Port Free Trade Zone in 2015, Kuaitu Turbine Technology is a **high-tech enterprise** specialized in the research, development, manufacturing, and sales of fluid machinery. All of its products are developed and manufactured in-house, boasting independent intellectual property rights. Over the past decade, Kuaite Turbine Technology has developed core technologies for three series: high-speed radial flow turbines, single-screw compressors and expanders, as well as permanent-magnet high-speed motors and permanent-magnet high-speed generators. Among them, the high-efficiency, high-speed, high-load radial flow turbine technology is an advanced technology unique to China and leading internationally; it fills the gap in the lack of high-efficiency prime movers in the megawatt power range. It is currently the most efficient prime mover in this power range, with an efficiency that can exceed 90%. Technology is the primary driving force, talent is the primary resource, and innovation is the main catalyst. “The Party’s *report emphasizes the need to rely on self-reliance and strength in science and technology, as well as to leverage talent as a driving force; it calls for efforts to cultivate top-tier innovative talents and to bring together the best minds from around the world to utilize their skills. We place particular emphasis on our ability for independent research and development, respect talent, and improve the strategic planning for talent development. ”Guo Xiangjie, chairman of Kuaituo Turbine Technology, explained that the company’s main R&D and design staff come from renowned institutions such as Tsinghua University, the Chinese Academy of Sciences, Beihang University, Harbin Institute of Technology, Tianjin University, and the University of Cambridge in the UK, with most of them holding doctoral or master’s degrees. The core members of its R&D team have many years of experience in the theoretical research, design, and manufacturing of aerospace engines, possessing a solid theoretical foundation as well as practical manufacturing expertise in high-speed, high-load, high-precision fluid machinery. In the view of Guo Xiangjie, carrying out original and pioneering scientific and technological research requires a strong talent base and technical support. Kuai Turbo Technology also maintains close cooperation with institutions such as Tsinghua University, the Chinese Academy of Sciences, Peking University, Beihang University, and Tianjin University. “For example, we have established a joint laboratory with Tianjin University and are an industry-academia-research partner of that university; we also maintain long-term cooperative relationships with the Aeroengine Test Laboratory at Beihang University and the Aeroengine Research Institute at Tsinghua University.
