The lifting of this tower was carried out by the Shanxi branch of Thirteenth Chemical Construction Company, which is responsible for building this project. It is reported that the ammonia synthesis tower weighs 82 tons and is 17 meters tall; it is lifted using a 460-ton truck crane as the main lifting device, with a 100-ton truck crane used for assisting with the lift. This lifting operation is the first major lift since the project began. Henan Shenma Industrial Co., Ltd. has invested 733.0051 million yuan in a project for the comprehensive utilization of 40,000 Nm3/h of coke oven gas. Located in the Shilong Industrial Cluster in Pingdingshan City, this facility uses coke oven gas from Dongxin Coking as raw material to produce liquefied natural gas (LNG), liquid ammonia, and industrial-grade CO2, while also generating steam and ammonia water as by-products. The project mainly consists of a production unit area, a utility and auxiliary facilities area, a storage and transportation facilities area, and a production management facilities area. Coke oven gas undergoes processes such as purification, desulfurization, shift reaction, decarburization, methanation, deep cryogenic separation, and ammonia synthesis to produce LNG, carbon dioxide, and ammonia. The annual production amounts to 63,300 tons of LNG, 89,400 tons of liquid ammonia, 50,000 tons of liquid carbon dioxide, as well as 20,000 tons of ammonia water as a by-product. The project’s process equipment includes a coke oven gas compression and purification unit (comprising units for coke oven gas pretreatment, compression, purification, CO conversion to produce CO2, decarburization, methanation, drying, etc.), an LNG cryogenic separation unit (including methanation, dehydration and purification, mercury removal to prevent damage to the aluminum components of the cryogenic chamber, dust filtration using microporous paper filters, and cryogenic separation), an ammonia synthesis plant (for nitrogen production via air separation, compression of hydrogen and nitrogen mixtures, ammonia synthesis, and ammonia freezing), a carbon dioxide purification unit, and an air separation nitrogen production unit, among others.
