【Progress of Haichuan Project】Fujian Haiquan Chemical’s BDO and PBT project using the alkyne aldehyde method in the United States has been mechanically completed
Thread Content
Recently, Fujian Haiquan Chemical’s project with an annual production capacity of 36,000 tons of 1,4-butanediol (BDO) and 60,000 tons of butylene terephthalate (PBT) has been mechanically completed. The fire safety inspections as well as expert evaluations regarding the conditions for pilot production have been carried out successfully, and the plant is now capable of producing high-quality formaldehyde products as well as top-grade BDO products. Project Overview: Haiquan Chemical is a key project in Fujian Province, with an annual production capacity of 36,000 tons of BDO and 60,000 tons of PBT products. The total investment in this project amounts to 760 million yuan. The main production facilities include a BDO production plant with an annual capacity of 36,000 tons (comprising a 36,000-ton/year BDO main unit, an 10,000-ton/year acetylene unit, and a 100,000-ton/year formaldehyde unit), as well as a PBT production plant with an annual capacity of 60,000 tons (including a 60,000-ton/year PBT main unit and a 0,400-ton/year THF recovery unit). After the project was relocated to the Gulei Petrochemical Complex, the original production processes, scale, and main equipment remained unchanged, while auxiliary and supporting facilities were added. It is understood that BDO uses the acrylonitrile process developed by the American company INVISTA to produce BDO. This advanced technology enables the production of BDO products with high concentrations and high quality, which has earned it high recognition from downstream manufacturers. PBT utilizes the existing direct esterification process developed by the German company LURGI; this technology is mature and reliable, features low consumption, produces high-quality products and by-products, and is backed by advanced equipment with a compact layout.
On January 3, 2022, at the beginning of the new year, the inauguration ceremony for Fujian Haiquan Chemical Co., Ltd. under Fujian Energy and Chemical Group, along with the launch ceremony for a series of projects, was held grandly at the Gulei Petrochemical Base in Zhangzhou. The total investment planned for the series of projects launched by Fujian Energy Chemical Group this time is 10.8 billion yuan, with a land area of 990 mu. The construction is scheduled to take place in two phases; Haiquan Chemical Company is intended to handle the relocation and development of the enterprises located in the Quangang chlor-alkali area of the group, and 5 sub-projects will be built at the Gulei petrochemical complex. The total investment for one of these phases is 7.2 billion yuan. The projects to be constructed include: one vinyl acetate plant with an annual production capacity of 200,000 tons, one PO/SM plant using a combined production method with annual capacities of 200,000/450,000 tons, one PPG plant with an annual capacity of 200,000 tons, one BDO plant with an annual capacity of 36,000 tons, and one PBT plant with an annual capacity of 60,000 tons ； The total investment for the second-phase project is 3.6 billion yuan, with the plan to build one propane dehydrogenation unit with an annual capacity of 900,000 tons. Upon completion of the project, it is expected to generate an annual industrial output value of 12.8 billion yuan, while the two phases of the project are expected to yield an annual tax revenue of 1 billion yuan.
