【Haichuan Chemical Salary News】Lanshi Heavy Equipment has completed the production and shipment of the hydrogenation and refining reactor for Shaanxi Jingyi
Thread Content
Recently, the hydrogenation refining reactor for the 450,000 tons per year fixed-bed hydrocracking unit intended for the deep processing and multi-product utilization of coal tar at Shaanxi Jingyi Chemical Co., Ltd., which was manufactured by Workshop 1 for welding and assembly at Lansi Heavy Equipment Company, was completed and shipped. This hydrogenation reactor is a large-thickness, large-diameter, high-tonnage vanadium-added steel forged and welded structure product manufactured at the Lanzhou facility of Lanshi Heavy Equipment. Since the start of production, the production, technical departments, and workshops have worked together to overcome various challenges. By drawing on past experience in manufacturing vanadium-added steel plate hydrogenation reactors, they identified the difficulties involved in production, optimized the manufacturing processes, allocated resources efficiently, and ensured strict accountability, thereby accelerating the production pace. During the manufacturing process, Workshop 1 for fitting and welding overcame the challenge of reheat cracks that easily occur during the welding of vanadium-added steel, ensuring a first-pass success rate for the main welds ； The use of a large number of high-end automated welding devices reduces labor intensity and shortens the production cycle.

On August 21, the signing ceremony for the 500,000 tons per year coal tar deep processing and multi-product integrated utilization project of Shaanxi Jingyi Chemical Co., Ltd. was held in the Jinjie Industrial Park in Shenmu City, and the first shareholders’ meeting as well as the first board meeting of its first term were convened. Shaanxi Yulin Energy Group Co., Ltd., Shaanxi Hengyuan Investment Group Co., Ltd. and Shenmu Financial Holding Group Co., Ltd. signed an investment cooperation agreement. At the ceremony, Hu Shaohua, Executive Deputy General Manager of Shaanxi Yulin Energy Group Co., Ltd., Sun Zhizhong, Chairman of Shaanxi Hengyuan Investment Group Co., Ltd., and Han Hongfeng, Deputy General Manager of Shenmu City Financial Holding Group Co., Ltd., signed the \"Investment Cooperation Agreement for Shaanxi Jingyi Chemical Co., Ltd.\" on behalf of the three parties respectively. Adhering to the principles of \"complementary resources, coordinated development, and mutual benefit,\" the three parties have embarked on cooperation regarding Shaanxi Jingyi Chemical Co., Ltd.’s 500,000 tons per year coal tar deep processing and multi-product integrated utilization project, as well as its subsequent development and construction.
The coal tar deep processing and multi-product integrated utilization project of Shaanxi Jingyi Chemical Co., Ltd. is located in the Jinjie Industrial Park in Shenmu City, covering an area of about 1,200 mu with a total investment of 4.6 billion yuan. It is a new chemical industry project invested and constructed by Shaanxi Hengyuan Investment Group Co., Ltd. The projects mainly include: a 550,000-ton/year coal tar pretreatment unit, a 500,000-ton/year coal tar fluidized-bed hydrocracking unit, a 450,000-ton/year coal tar fixed-bed hydrocracking unit, a 400,000-ton/year naphtha continuous reforming unit, a 170,000-ton/year aromatic extraction unit, a 50,000 cubic meters per hour coal-to-hydrogen unit, a 50,000 cubic meters per hour air separation unit, a 100,000-ton/year methanol synthesis unit, as well as related supporting facilities such as hydrogen purification (PSA) units, sulfur recovery units, phenol-amine recovery units, storage and transportation systems, and other auxiliary and environmental protection systems.
Recently, the hydrogen production unit of Shaanxi Jingyi Chemical Co., Ltd.’s project for the deep processing and integrated utilization of coal tar was inaugurated. This project is being constructed by the Shaanxi branch of China National Chemical Engineering Corporation Third Construction Company. Located in the Jinjie Industrial Park in Shenmu City, Shaanxi Province, it was funded by Shaanxi Hengyuan Coal and Electricity Group Co., Ltd. With a total investment of 4.69 billion yuan, it represents the first large-scale coal-based aromatic compounds production line in China to date.
The project utilizes a hydrogenation technology that combines a fluidized bed with a fixed-bed reactor, using the full distillate of coal tar as raw material; through hydrocracking, naphtha catalytic reforming, and aromatic extraction, it primarily produces phenolic products and benzene-based products. Construction contents – 1.2 million tons/year new-type raw coal pyrolysis unit, 600,000 tons/year coal tar pretreatment unit, 40,000 tons/year defenolization and phenol refining unit, 500,000 tons/year fluidized bed hydrocracking unit, 450,000 tons/year fixed-bed hydrocracking unit, 400,000 tons/year continuous reforming unit, 240,000 tons/year aromatic extraction unit, 40,000 standard cubic meters/hour coal-to-hydrogen unit, 0.8 million tons/year sulfur recovery unit, 30,000 standard cubic meters/hour hydrogen purification (PSA) unit, 3×160 t/h boilers + 2×30 MW steam-driven power generation units, etc
The market prospects for coal tar hydrogenation projects are not optimistic.
This has been discussed before; raw material collection is an issue
The previous project seemed to be in Ningxia
It is in that triangular area, the regions where coking coal is produced, such as Ordos in Inner Mongolia, Yulin and Fugu in Shaanxi, Yinchuan in Ningxia, and Datong in Shanxi.
