Lanshi Delivers Six Large Gas-Liquid Multiphase Welded Heat Exchangers for a National Coal Conversion Demonstration Project
Lanzhou Lanshi Heat Exchange Equipment Co., Ltd. has completed six large gas-liquid multiphase welded heat exchangers for the acrylic acid unit of a demonstration project for the staged, clean and efficient conversion of coal, and has shipped them fully assembled to the customer's site. The delivery marks another important breakthrough for the company in high-end heat exchange equipment for the coal chemical industry and provides solid equipment support for a national demonstration project in clean and efficient coal utilization.
The project focuses on the efficient conversion and clean use of coal resources, tackling the high energy consumption and high emissions of traditional coal chemical processes. It is an important demonstration for optimizing China's energy mix and achieving its carbon peaking and carbon neutrality goals.
The heat exchangers use advanced gas-liquid multiphase flow heat transfer technology and offer a compact structure, a high degree of integration, ultra-low pressure drop and an even flue gas flow distribution. While providing a large heat transfer area and high efficiency, they also reduce the project's footprint and construction costs and lower operating energy consumption.
To cope with the flammable, toxic and highly corrosive media found in coal chemical processes, the design and manufacture of the units focused on strengthening resistance to high temperature, high pressure and corrosion, and the units are fitted with a dedicated sealing structure for safe, stable long-term operation with complex media.
In recent years, Lanshi has continued to focus on the R&D and manufacture of high-end heat exchange equipment and has steadily increased its investment in innovation, achieving breakthroughs in domestically producing key equipment for petrochemicals, coal chemicals, nuclear power and new energy. The company was deeply involved in "Chaotan No. 1", the demonstration project for the world's first commercial supercritical CO₂ power generating unit, where it worked with research institutes to master core technologies such as vacuum diffusion bonding for high-efficiency microchannel heat exchangers and successfully developed the key recuperators.
Going forward, Lanshi will continue its innovation-driven development strategy, focus on manufacturing high-end heat exchange equipment, keep strengthening its core technologies, and contribute more solutions to the high-quality development of the energy and chemical industries.
