Project for the Upgrading of Clean Production Technologies for Project 40.60 at Shandong Lianmeng Chemical Co., Ltd. Author/Source: Shandong Lianmeng Chemical Co., Ltd. Date: 2020-08-10 Clicks: 19 I. Project Overview Project Name: Project for the Upgrading of Clean Production Technologies for Project 40.60 at Shandong Lianmeng Chemical Co., Ltd. Location of Construction: Houzhen Chemical Industrial Park, Shouguang. Nature of the Project: Technical upgrade. Project Summary: Shandong Lianmeng Chemical Co., Ltd. is a large-scale chemical manufacturing enterprise that focuses on coal-based chemical production. 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 Industrial 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. 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 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.
