【HaiChuan Chemical Project Updates】Binzhou Xinmin’s high-end energy project for producing 300,000 tons of coal-based ethylene glycol is set to start operations in October
Thread Content
The 300,000-ton per year coal-to-ethylene glycol production project in the Xinmin High-End Energy and Chemical Industry Park of Binzhou City is funded by Shaanxi Coal Weihe Group Company. It is constructed and operated by Weihe Binzhou Chemical Company, a wholly-owned subsidiary of Weihe Group. The estimated investment for this project is 5.4 billion yuan; it covers an area of 900 mu, and the facilities require 1.4 million tons of raw coal as well as 10 million cubic meters of water per year. The project utilizes mature and advanced process technologies such as pressurized gasification of water-coal slurry and low-temperature methanol washing, with a designed annual production capacity of 300,000 tons of ethylene glycol. Upon completion, it is expected to generate annual operating revenue of 2.2 billion yuan and a profit of 540 million yuan, while creating employment for over 1,000 people.
This project saw an investment of 560 million yuan this year, bringing the total cumulative investment to 5.032 billion yuan. The office building, control building, and laboratory building in the factory’s front area have been completed; the office building is already in use ； The plant’s road network and various underground pipeline systems have been fully completed; the air compression station, startup boilers, and hydrogen production equipment have also been mechanically finished ； The single test of the raw water pump was completed, power was supplied to the sewage treatment substation, and Boiler No. 1 was started up ； In conjunction with the commissioning of the water transmission pipeline for the Hongyanhe Reservoir, water intake is proceeding normally ； Installation of transformers at the DMO substation has begun ； The hoisting of the material picker at the strip material yard has been completed ； The commissioning of circulating water systems, reclaimed water reuse systems, and wastewater treatment systems, as well as the piping work for various chemical processing units, has been completed; preparations are now in progress for the purging of instrument air and plant air pipelines. Planning to carry out chemical feeding trial operations in October. At the project construction site, we saw workers working in an orderly manner, with various mechanical equipment operating in their respective positions; the entire site was bustling and lively. It is understood that at the project site, more than twenty construction units are carrying out tasks such as pipeline installation, welding, equipment calibration, and exterior decoration, making active preparations for the project to start trial operations.

On June 3, 2019, at the construction site of the 300,000-ton/year coal-to-ethylene glycol project in the Xinmin High-End Energy and Chemical Industry Park in Binzhou City, Shaanxi Province, the main framework of the gasification unit was completed once the last batch of cement was poured. The deputy general manager of WeiHua Group, the executive deputy commander of the ethylene glycol project department, and the deputy general manager of China National Chemical Engineering Corporation’s 13th Construction Company attended the ceremony. The main framework of the gasification plant is 52 meters tall; it is a 10-story reinforced concrete structure built by China National Chemical Engineering Corporation No. 13 Construction Co., Ltd. The entire project began in May 2018 and was completed on schedule within one year.
On July 10, 2019, all the tower vessels within the ethylene glycol production area of Shaanxi Weihe Binzhou Chemical Co., Ltd., part of the Shaanxi Coal and Chemical Industry Group’s 300,000 tons per year coal-based ethylene glycol production project, were assembled and installed. It is reported that the 300,000 tons per year ethylene glycol project features a total of 27 towers of 17 different types in the DMO area and the ethylene glycol area, all of which were manufactured by four different companies. Ten of these towers need to be fabricated and assembled on-site; some of them also require the assistance of 650-ton and 260-ton crawler cranes for assembly in the air above the foundation.
Construction of the MN regeneration towers began on site on October 24, 2018, with the arrival of the first tower at the project site. Despite harsh conditions such as extreme cold, exposure to sunlight and rain, and under the leadership of the group company and the project construction command center, the ethylene glycol project team coordinated closely with all parties involved. The three companies started manufacturing the towers simultaneously, and after more than 200 days of work, the final tower, the high-pressure methanol distillation tower T4404, was assembled in place on July 10. This marked the completion of the installation of all the large-scale towers in the ethylene glycol area, and it also signified that the installation phase of the ethylene glycol project had reached its peak.
The construction site for the 300,000 tons per year coal-based ethylene glycol production facility of Shaanxi Weihe Binzhou Chemical Co., Ltd., which belongs to the Shaanxi Coal Chemical Weihe Group, is located within the Xinminyuan Modern Coal Chemical Industrial Park in Bin County, covering an area of 600,000 square meters. In April 2016, Shaanxi Weihe Binzhou Chemical Co., Ltd. signed a CTEG technology licensing agreement and an engineering design contract for a 300,000 tons per year coal-based ethylene glycol project with Gaoxuehua and Donghua Engineering. The original owner of the project was Shaanxi Binchang Mining Group Co., Ltd. On November 19, 2014, the 300,000-ton coal-to-ethylene glycol project of Binchang Mining Group was officially transferred to Shaanxi Weihe Coal Chemical Industry Group Co., Ltd.
