[Chemical Equipment Powerful Country and Important Equipment] 068-Shanxi manufactures large-scale ammonia synthesis tower
Thread Content
The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * On January 2, 2019, the ammonia synthesis tower and thermal regeneration tower produced by Shanxi Yangmei Chemical Machinery (Group) Co., Ltd. for Hubei Yichang Xingxing Blue Sky Technology Co., Ltd. have been loaded and ready for shipment. They will arrive at Yichang Xingxing Blue Sky in the near future, providing a solid equipment foundation for the production and operation of Yichang Xingxing Blue Sky's synthetic ammonia and other chemical products.

The ammonia synthesis tower is developed and manufactured by the Jinhua Furnace Branch of Yangmei Chemical Machinery Taiyuan Base. The thermal regeneration tower is developed and manufactured by the Heavy Container Branch of Yangmei Chemical Machinery Taiyuan Base. The ammonia synthesis tower and the thermal regeneration tower are the heart of the ammonia synthesis plant. They are reactors with extremely complex structures. They are equipment used to catalytically react nitrogen and hydrogen at high pressure and high temperature for ammonia synthesis. They have extremely high requirements on pressure and temperature. Considering these harsh conditions, the company uses 12mm thick steel plates for laminate rolling to ensure that the ammonia synthesis tower can fully withstand the working pressure of 14.2MPa and the working temperature of 185°C during operation and startup. The ammonia synthesis tower has a total height of 27.1m, a barrel diameter of 2.4m, a total volume of 112.3m3, and a net weight of 384t, which is the largest and highest in China so far. At the same time, the supporting equipment thermal regeneration tower uses 14mm thick steel plates to roll the cylinder and perform assembly and welding to ensure that it can reach a working pressure of 0.22MPa and an operating temperature of 88.3°C (tower top) and 101.92°C (tower bottom) during normal operation.
On January 10, 2021, the key equipment inlet and outlet heat exchanger produced by the heat exchanger branch of Taiyuan Base of Yangzhou Coal Chemical Machinery Co., Ltd. for the fine chemical and new material recycling project of Shanxi Xin Xinneng Technology Co., Ltd.'s coke oven gas production 300,000 tons/year methanol co-production synthetic ammonia project successfully completed loading and is about to embark on the road to Qingxu, Taiyuan. This move is of great significance for Yangmei Chemical Machinery to establish long-term friendly cooperative relations with customers and enhance the company's chemical equipment manufacturing competitiveness.
