It has been reported recently that the civil construction work for Shandong Union Chemical Co., Ltd.’s 40·60 project’s clean production technology upgrade has been completed, as well as the equipment installation; trial operation is expected to start in August. On May 5, the construction of the trestle for the filter press building in the upgrade project of Shandong Lianmeng Chemical’s 40∙60 facility was completed, with the work carried out by the East China branch of Erhua Jian. The assembly of the filter press trestle is a key aspect in ensuring proper ventilation throughout the entire plant process in the filter press facility. The total investment for the project is 2.926 billion yuan, and it involves upgrading the existing fixed-bed batch gas production process by using space-based powder coal gasification, low-temperature methanol washing, and liquid nitrogen washing technologies. The designed production capacity is 600,000 tons of synthetic ammonia, 200,000 tons of methanol, and 80 million cubic meters of hydrogen per year. The project adheres to international standards and introduces revolutionary improvements to the gasification process. It involves the construction of 15 individual units such as gasification islands and raw coal silos; the previous 44 atmospheric pressure gasifiers will be completely replaced by 2 pressurized gasifiers. Once in operation, the system will enable fully automated and intelligent control. Project Overview: Location of construction: Houzhen Chemical Industry Park, Shouguang, Shandong. Nature of the project: Technical renovation. Project summary: Shandong Lianmeng Chemical Co., Ltd. is a large-scale chemical manufacturing enterprise that focuses on coal chemical products. The company’s main business activities include the production and sales of urea, synthetic ammonia, methanol, liquid CO2, and sulfur ； Production and sales of related fine chemical products ； Import and export operations within the scope permitted by the qualification certificate. The existing “40.60” project is a relocation initiative carried out by the Union Joint Stock Company in 2011, aiming to move all production facilities located in the urban area to the Houzhen Chemical Industry Park; it was completed and put into operation by the end of 2012. The current production capacity is 400,000 tons per year of synthetic ammonia, 200,000 tons per year of methanol, and 600,000 tons per year of urea. The 40.60 Project’s clean production technology upgrade project involves modifying only the ammonia synthesis section of the existing “40.60” Project; upon completion of the upgrades, the annual production capacity of ammonia will remain at 400,000 tons, urea at 600,000 tons, and methanol at 200,000 tons. After the technical upgrade, the gas production process was changed from a fixed-bed batch method to a pressurized coal gasification process ； The original 2 sets of desulfurization units, 3 sets of shift units, 2 sets of shift gas desulfurization units, 2 sets of PSA pressure swing adsorption decarburization units, and 2 sets of high-pressure alcohol alkanation units were replaced by 1 set of isothermal shift unit, 1 set of low-temperature methanol washing unit, and 1 set of liquid nitrogen washing unit respectively ； The ammonia synthesis process has been changed from 2 sets of high-pressure synthesis units to 1 set of low-pressure synthesis unit, with the operating pressure reduced from 22 MPa to 15 MPa ； Complementary air separation units and waste gas treatment units are to be installed.
