On March 1, the inauguration ceremony for the ammonia evaporation unit of the syngas purification system was held for the Olefins, Aromatics and Deep Processing Project (Phase I) of Shaanxi Coal Group Yulin Chemical Co., Ltd.’s 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products. This key milestone marks a new phase in the environmental protection upgrades and process technology optimizations for Phase 1 of Project Phase II. The ammonia vaporization unit is a key environmental protection component of the syngas purification system; it plays an important role in the efficient recovery and thorough purification of ammonia-containing fluids throughout the production process. Its purpose is to achieve three objectives: the recycling of ammonia resources, the reduction of wastewater emissions to meet regulatory standards, and the optimal and stable operation of the facility. The project integrates an advanced integrated process of stripping, acid removal, ammonia evaporation, and refining, offering advantages such as high treatment efficiency, low overall energy consumption, and safe and stable operation. Once operational, it will significantly improve the level of clean production in the facility, providing solid support for the enterprise’s efforts to save energy, reduce carbon emissions, and enhance inherent safety. The first phase of the second phase of the Yulin Chemical project of Shaanxi Coal Group uses 9 3,500-ton-class space furnaces. The project includes 5.6 million tons per year of methanol, 1.5 million tons per year of methanol-to-olefins production, 300,000 tons per year of polyethylene (FDPE), and 300,000 tons per year of polypropylene (PP), among other things.
