On January 30, the third alcohol tower of the 300,000 tons/year caprolactam project of Yankuang Lunan Chemical Co., Ltd. constructed by China Chemical Tianchen Company was successfully hoisted in place. The third alcohol tower was the last of the seven over-limit towers produced on site. One. The smooth hoisting of this equipment marks the successful completion of the on-site installation of over-limit equipment. It is an important milestone for the project construction and lays a solid foundation for the completion of the project on schedule.

　　Due to the epidemic situation and the rare extreme weather at the project site, the progress of the on-site manufacturing of over-limit towers was affected. Overrun towers belong to large-piece hoisting, which is a critical path for project construction and has a great impact on the overall progress of the project. According to the equipment manufacturing situation and the overall project progress goal, the project department held several special meetings with the manufacturer in a timely manner to formulate corrective measures, coordinate the conditions of the site and crane, and the manufacturer organizes continuous construction of skilled workers in day and night shifts to fight for progress.

　　In order to speed up the hoisting progress, the project department adjusted the crane selection and tower segmentation plan, and used 1,250-ton cranes to enter the site to reduce the number of original aerial pairings, which greatly reduced the risk of high-altitude operations and effectively saved the hoisting time. The hoisting work of all large equipment was completed within time.

　　Brief Introduction of 300,000 Tons/Year Caprolactam Project of Yankuang Lunan Chemical Co., Ltd

　　The total investment of the 300,000 tons/year caprolactam project of Yankuang Lunan Chemical Co., Ltd. is about 3.755 billion yuan. It is located in the courtyard of Yankuang Lunan Chemical Co., Ltd. in Lunan High-tech Chemical Park. The construction of a set of equipment with an annual output of 270,000 tons of cyclohexanone and 300,000 tons of caprolactam and a by-product of 60,000 tons of cyclohexane and 400,000 tons of ammonium sulfate and supporting auxiliary equipment is a key project for the conversion of new and old kinetic energy in Shandong Province.

　　The project adopts the international advanced ammoximation method to produce caprolactam technology. The process route has the advantages of reasonable flow, small amount of by-products, low equipment investment, low consumption indicators, small environmental impact, and good product quality. After the device is successfully put into production, the products will be It can meet the product quality requirements of the high-end caprolactam market, which is mainly high-speed spinning chips. It not only brings considerable economic benefits, but also realizes the transformation from traditional coal chemical enterprises to high-end chemical and new materials. It is of great significance to promote the high-quality development of enterprises and regional economic and social.

　　The process units are mainly cyclohexanone unit, caprolactam unit (including ammoximation unit, liquid phase rearrangement unit, neutralization crystallization unit), hydrogen peroxide unit, sulfuric acid unit (the cyclohexanone unit is a single line with a single-line production capacity of 270,000 Tons/year; the hydrogen peroxide device is a single line with a single-line production capacity of 400,000 tons/year; the sulfuric acid device is a single line with a single-line production capacity of 400,000 tons/year; the ammoximation device is a single line with a single-line production capacity of 300,000 tons/year Wait.
