On April 13, as the waste boiler of the incinerator successfully arrived at the factory, Donghua Engineering Technology Co., Ltd. PC (Procurement, Construction) general contracted Shanxi Meijin Huasheng Chemical New Materials Co., Ltd. to produce 300,000 tons of comprehensive exhaust gas The arrival of more than 300 non-standard equipment for the annual ethylene glycol co-production LNG project came to a successful conclusion.
The project has a tight construction period and complex site conditions. The incinerator waste pot has a diameter of 3.2 meters, a length of 11.2 meters, and a weight of 115 tons. The low-pressure and low-calorific value exhaust gas of the project is It plays an important role in processing and heat energy recovery. The transportation routes passing through four provinces have become a difficult problem for this delivery and arrival work. After the efforts of all parties, the project completed the transportation work spanning thousands of kilometers in just 72 hours. The acceptance was completed and the hoisting was successful on the same day, ensuring the orderly progress of the project.
As of March 31, 2021, the overall ethylene glycol project of Shanxi Meijin Huasheng Chemical New Materials Co., Ltd. has been completed at 79.4%. The process pipeline welding has completed 300,000 dynes, and the first pass rate of welding flaw detection is 99.41%. Currently, the project is undergoing desalination station commissioning, hydraulic pressure testing of tower equipment, and circulating water pre-filming. The project is sprinting towards the goal of “730 mechanical completions”.
Project Overview
Shanxi Meijin Huasheng comprehensive exhaust gas production of 300,000 tons of ethylene glycol combined The LNG production project is a 4-million-ton coking and extended supporting project built by Shanxi Meijin Energy Co., Ltd. in the Qingxu County Economic Development Zone in Taiyuan. Once completed, the project will help the coking industry in Shanxi Province reduce excess production capacity and fight against pollution.
The project is located in the Fine Chemical Cycle Industrial Park in Qingxu County, Taiyuan City, Shanxi Province. It uses coke oven gas to enrich hydrogen and blast furnace gas and converter gas to enrich carbon. Characteristics, three kinds of gas coupling, production of high-end chemicals, adhering to the new concept of improving the coupling of coking, metallurgy and chemical industry, aiming at high efficiency and low energy consumption, realizing a new pattern of organic integration and coordinated development of coking and modern coal chemical industry, creating High-tech, high-value-added fine coking chemical products promote the green transformation of China’s coking industry by taking coking products-renewable resources-recycling as a path.
The main construction contents of the project include coke oven gas/converter gas/blast furnace gas purification device, H2/CO separation device, dimethyl oxalate device, ethylene glycol device, and whole-plant storage transportation equipment, air separation equipment, etc. and other public auxiliary and supporting systems.
The project will be implemented in two phases. The first phase will construct 3 million tons/year coking and supporting chemical product recycling, and use the excess coke oven gas and new metal materials from the coking device to produce The project’s silicon-manganese tail gas is coupled to produce 300,000 tons/year of ethylene glycol and 160,000 tons/year of LNG. The tar by-product of the coking unit is used to build a 400,000-ton tar processing 150,000-ton carbon black project. The second phase of the project will construct 3 million tons/year of coking and supporting chemical product recovery, and use the excess coke oven gas from the coking unit to produce 300,000 tons/year of ethylene glycol, with a by-product of 80 million standard cubic meters/year of hydrogen. </p
