Recently, the public announcement was made regarding the first-phase acetic acid expansion and renovation project of the clean production demonstration project for optimizing the multi-nozzle water-cooled wall gasifier and its supporting systems at Yankuang Lunan Chemical Co., Ltd. Project Name: Phase I of the Optimized Clean Production Demonstration Project for Multi-nozzle Water-cooled Wall Gasifier and Associated Systems – Acetic Acid Expansion and Renovation Project. Construction Content and Production Scale: Transformation is carried out within the framework of the existing Acetic Acid Unit 1 and Acetic Acid Unit 2 by adding or replacing equipment. Through renovation and expansion, the production capacity of the existing two acetic acid plants will be increased from 600,000 tons per year to 1 million tons per year. Specifically, the capacity of Plant 1 for acetic acid will rise from 300,000 tons per year to 400,000 tons per year, while the capacity of Plant 2 will increase from 300,000 tons per year to 600,000 tons per year. The methanol required for the expansion of acetic acid production is allocated from across the entire plant, with any shortfall purchased externally. The project relies on existing public facilities such as water supply, power supply, gas supply, heating, flare systems, and sewage treatment. Construction location: The proposed project is located within the existing facility of Yankuang Lunan Chemical Co., Ltd. in the Lunan High-Tech Chemical Park, and will be built within the existing Acetic Acid 1 and Acetic Acid 2 facilities, all situated in the western part of the plant. Investment amount: 129.79 million yuan ； The planned construction period is 20 months.
