The Lutianhua GreenSource Alcohol air separation unit and methanol plant were successfully commissioned. Author/Source: Lutianhua Date: 2022-03-09 Clicks: 7 On March 3, the GreenSource Alcohol air separation unit and methanol plant were successfully put into operation. Spring has arrived, and the weather is gradually warming up. On February 26, Lutianhua Co., Ltd. received notice from CNPC that gas supply had been restored, allowing the Lvyuan Alcohol Methanol plant to resume operations. As the orange warning for severe air pollution was in effect in Naxi District, the company’s management promptly instructed the Safety Supervision Department to submit an application to the district’s Ecology and Environment Bureau regarding the resumption of production. The Production Management Department quickly prepared and issued a comprehensive schedule for starting up operations, issued orders for the commencement of production, and informed departments such as the Equipment Department, Security Department, and Materials Supply Company about the need to get production underway. Upon receiving the notice, everyone became motivated and full of energy, committed to providing excellent service and guidance, and striving with all their might. At the same time, we cherish every opportunity to drive, strengthen emergency response measures during driving, continuously raise awareness of costs and energy conservation, and strive to reduce consumption related to driving. On February 27, the Production Management Department and the Safety Supervision Department took the lead in verifying the conditions necessary for resuming operations of the plant, as well as the conditions required for starting up the equipment. Special inspections were carried out regarding technical improvements, changes, interlocks, and related training programs. Process supervisors and dispatch personnel were on duty 24/7 to ensure that the workshops followed the detailed energy-saving operating procedures. During the startup process, hydrogen was recycled to reduce consumption, process control was strengthened, and real-time monitoring was maintained; data on the site conditions and the surrounding environment was reported regularly to prevent environmental pollution and complaints from local residents. At 14:25 on March 2, with the oxygen and nitrogen produced by air separation meeting the required standards, and the successful introduction of gas into the methanol synthesis tower at 2:50 the following day, it was confirmed that the plant had been successfully started up for operation.
A technical upgrade project for the construction of a 400,000-ton/year methanol production facility utilizing syngas is being carried out within the existing plant premises of Sichuan Lutianhua Lvyuan Alcohol Industry Co., Ltd. in the Naxi Chemical Industrial Park of Luzhou City. The main aspects of this upgrade involve: the original production process of the facility will not be changed; instead, the methanol synthesis gas obtained from desulfurization of natural gas will be replaced with coal-based methanol synthesis gas provided by a coal gasification company, and the associated equipment will be modified accordingly; The project will construct a hybrid combustion boiler along with associated heat recovery equipment to treat the combustible waste gases generated by this project and the Synthesis Unit 1 of Luzhou Tianhua Chemical Co., Ltd. Upon completion of this project, it will have an annual production capacity of 400,000 tons of methanol. The total investment for the project is 34.41 million yuan, of which 370,000 yuan is allocated to environmental protection measures, accounting for 1.08% of the total investment.
