At 16:00 on June 14, as the 400-ton tower crane successfully lifted the last cold box board, the company's key technical transformation project, the air separation argon project, completed the cold box ceiling, one day ahead of the planned construction period, marking the completion of the hoisting of an additional 63 meters of cold boxes, rectification towers and large equipment, the overall project has been completed nearly 60%, and the construction of argon production project has taken a solid step. It has laid a solid foundation for the subsequent production on schedule, the production of new products and the improvement of economic benefits.

Liquid argon has important application value in industry, which can be used in the production of high purity silicon and germanium crystal protection gas, active metal shielding gas, chromatographic carrier gas, special steel blowing gas, welding protection gas, etc., and also has a wide range of applications in the fields of electronics, optoelectronics and particle physics. After the completion of the air separation argon project, the utilization efficiency of the existing air separation unit will be improved, and the new products such as high-purity liquid argon produced can greatly meet the market demand and further improve the profitability of the unit.

The coal-to-oil sub-company attaches great importance to the work of technical transformation, adheres to the two aspects of safety production and development and construction, two promotion, focusing on three aspects of device transformation and upgrading, namely: focus on material and energy balance management, constantly improve the overall efficiency of the system, and seize the system thinking to reduce costs and increase efficiency and energy saving and emission reduction; Focus on revitalizing assets to improve plant utilization, and improve the production efficiency of existing plants with innovative thinking; Focus on "high-end, diversified, low-carbon" development to focus on new product development, and continue to expand and enrich product categories with strategic thinking and market orientation. In order to accelerate the implementation of the established projects, the branch company sorted out more detailed project progress planning for key projects such as air division argon and formulated assessment requirements, paid attention to the progress of the work every day, held weekly technical reform and engineering meetings, systematically arranged and deployed technical reform work, coordinated and urged progress, and fully promoted the implementation of the project.
