Over the past decade, there has been tremendous development in chemical engineering equipment; long live the prosperous and powerful China! Wishing everyone a happy New Year and good health for you and your families. This is just a starting point—let’s all get involved to make things more lively. Haichuan becomes even more wonderful with your participation; we welcome everyone to join in the discussions on the forum. ********************************************** On September 30, 2012, the largest vertical ammonia synthesis tower in China, manufactured using the integral multi-layer wrapping technique, was successfully completed at Aerospace Chen Guang Co., Ltd., a subsidiary of China Aerospace Science and Industry Corporation. The successful delivery of this equipment has established the company’s leading position in the coal chemical ammonia synthesis industry, particularly for ammonia synthesis towers over 2.4 meters in height. It is reported that this equipment is a key component in the synthesis unit of the facility designed for an annual production of 500,000 tons of synthetic ammonia; it weighs 500 tons, has a diameter of 2.8 meters, and a height of 30.4 meters, making its manufacture extremely difficult. Just to address the load-bearing issue at the production site, 10 roller frames were manufactured, with 8 tons of steel being used for the pads, which ensured the requirements for on-site fabrication and hydrostatic testing could be met. Moreover, resolving this issue also provided valuable experience for the future on-site manufacturing of large-scale equipment. With the development of new processes and technologies in coal chemical industry, during the 12th Five-Year Plan period, the development trend of large-scale coal chemical plant equipment was towards larger size and greater weight. It is reported that Aerospace Chenguang has upgraded its equipment from 98 tons 10 years ago to 500 tons today, and is steadily moving toward the development of ultra-large ammonia towers with a capacity of 1,000 tons in the future.
Nanhua Machinery was the first in the country to use the overall multi-layer wrapping technology in the manufacture of ammonia synthesis towers, many years ago.
The earliest one was the Aerospace Morning Light, which is also in Nanjing
