Recently, Ningxia Kunpeng Clean Energy Co., Ltd.’s 400,000-ton-annual coal-to-ethylene glycol project’s air separation unit #2 cold box successfully achieved structural capping.
The ethylene glycol project includes 2 sets of 68000Nm³/h air separation units. The cold box is an important part of the air separation unit, and the capping of the cold box marks an important node in the construction of the air separation unit. 2# cold box is 11.4m long, 7.9m wide and 67m high. The 2# cold box was capped successfully, laying a solid foundation for the project to be completed on schedule.
Ningxia Kunpeng Clean Energy Co., Ltd.’s annual output of 400,000 tons of coal-to-ethylene glycol project has a total investment of 4.33 billion Yuan, Ningxia Kunpeng’s 400,000 tons of ethylene glycol uses coal as raw material, Shenning furnace pulverized coal gasification, Japan’s high-chemical dimethyl oxalate production of ethylene glycol technology. The products are 400,000 tons/year ethylene glycol, 52,000 m3/h hydrogen and 400,000 tons/year combined alcohol. Among them, the combined alcohols include 328,000 tons of refined methanol and 36,200 tons of ethanol.
The main construction content includes 10 sets of main production equipment including gasification, conversion and heat recovery, low-temperature methanol washing, PSA hydrogen production, CO cryogenic separation, joint alcohol unit, sulfur recovery, ethylene glycol, etc., and supporting facilities Construct public and auxiliary facilities such as circulating water fields, sewage treatment stations, tank farms, loading and unloading, and flares. It is planned to clear the entire process on June 30, 2021.
Ningxia Kunpeng Clean Energy Co., Ltd. was established in August 2018. It is a wholly-owned subsidiary of Ningxia Baoli New Energy with a registered capital of 1.5 billion yuan. It is a high-tech enterprise in Ningdong Base. A key enterprise in clean energy production, the company cooperates with Ningdong Investment Company (30% investment) to build a coal-to-ethylene glycol project with an annual output of 400,000 tons.
The ethylene glycol project of Ningxia Kunpeng Clean Energy Co., Ltd. is jointly invested and constructed by Ningxia Baoli New Energy Co., Ltd. and Ningxia Ningdong Development Investment Co., Ltd. The company undertakes the construction of project power stations and air separation plant projects. This project is a demonstration project for the modern coal chemical industry. It is of great significance to Ningxia Ningdong Chemical Base to complete the industrial chain, accelerate industrial transformation and upgrading, and build a national-level modern coal chemical base with leading technology, industry leadership, and world-class status. </p
