The equipment has a net weight of 238 tons, a diameter of 4680 mm, and a total length of 18186 mm. The installation of the equipment this time marks the entry of the large-scale equipment installation phase of this project into its final stage, providing a solid guarantee for the early completion of the project. The Shandong Alliance 40∙60 project upgrades the conventional fixed-bed batch gas production process by employing space-based powder coal gasification, low-temperature methanol washing, and liquid nitrogen washing technologies. In addition, the pressure swing adsorption process will also be employed to purify H2 from the raw gas used in low-temperature methanol washing, in order to produce hydrogen for use as vehicle fuel. The project is scheduled to go into operation in 2023. The 40.60 Project 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. Following 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 alkylation 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.
