6月14日16:00，随着400吨塔吊将最后一块冷箱板成功吊装，公司重点技术改造项目空分制氩项目完成完成冷箱封顶，较计划工期提前1天，标志着新增63米冷箱、精馏塔及大件设备吊装完成，整体工程已完成近60%，制氩项目建设迈出了坚实的一步，为后续如期投产、生产新产品、提升经济效益奠定了坚实基础。

液氩在工业中具有重要的应用价值，可用于生产高纯硅锗晶体的保护气、活性金属屏蔽气体、色谱载气、特种钢吹炼气、焊接保护气等，在电子、光电子和粒子物理学等领域也有广泛的应用。空分制氩项目建成后将提升现有空分装置利用效能，产出的高纯度液氩等新产品，可极大满足市场需求，进一步提升装置盈利能力。

煤制油分公司高度重视技改攻坚工作，坚持安全生产与发展建设两手抓、两促进，聚焦三方面重点抓装置改造升级，即：聚焦物料和能量平衡管理不断提高系统整体效能，以系统思维抓降本增效和节能减排；聚焦盘活资产提高装置利用率，以创新思维提升现有装置生产效能；聚焦“高端化、多元化、低碳化”发展抓新产品开发，以战略思维和市场导向不断扩展丰富产品种类。为抓好既定项目的加速实施，分公司对空分制氩等重点项目梳理更加详细的工程进度统筹，并制定了考核要求，每日关注工作推进情况，每周召开技改及工程例会，系统安排部署技改工作，协调督促进度，全力推进项目实施。

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.
