Bid Invitation for the Preliminary Design of the Hazardous Waste Resource Recovery and Comprehensive Utilization Project in Lanzhou New Area
Thread Content
It was recently learned that a tender announcement for the preliminary design of a hazardous waste resource utilization project in Lanzhou New Area has been issued. Project Overview and Scope of Bidding: Constructor: Lanzhou New Area Lanxin Nengke Zhixin Energy Co., Ltd. Project Name: Preliminary Design for the Comprehensive Utilization of Hazardous Waste in Lanzhou New Area. Location of Construction: Within the Chemical Industry Park in Lanzhou New Area. Project scale: The new project will be constructed in two phases. The construction scope includes coal preparation, gasification (raw material pretreatment), conversion, low-temperature methanol washing, liquid nitrogen washing, sulfur recovery, ammonia synthesis, air separation, polyols, as well as supporting utility systems and auxiliary facilities. Funding source: Self-financed by the enterprise. Estimated total investment for the project: 2,127,374,800 yuan (Phase 1). Number of bid sections: 1 bid section. Scope of the tender: Phase I project. The construction scope of this project includes: production units: gasification unit, purification unit, ammonia synthesis unit, polyol unit, and air separation unit. Storage and transportation facilities: product storage tanks (including tanks for methanol, ethanol, propanol, butanol, and mixed alcohols), liquid ammonia storage tanks, waste liquid storage tanks, intermediate storage tanks, loading/unloading platforms, and coal preparation system. Utilities: power transformation and distribution room, circulating water plant, desalination station, heat exchange station. Supporting facilities: fire station, sewage treatment plant, elevated flare system, hazardous waste storage area, on-site office, maintenance workshop and spare parts warehouse, on-site laboratory, foam station, deluge valve room. On May 11, Zhixin Energy Company in Lanzhou New Area organized a review meeting for the feasibility study report on the project related to the comprehensive utilization of resources through the coordinated disposal of water-coal slurry and hazardous waste. The coal water slurry-based integrated resource utilization project for hazardous waste disposal employs an advanced domestic technology for mixing coal water slurry with hazardous waste. The hazardous waste generated by enterprises in the new chemical industrial park and those in the surrounding areas of Lanzhou is mixed with coal water slurry; after pyrolysis in a gasifier, syngas is produced, which is then used to manufacture 200,000 tons of ammonia and 260,000 tons of alcohols per year. The types of hazardous waste handled by this project include 14 major categories and 155 subcategories, such as waste organic solvents and distillation residues. This approach helps to reduce reliance on natural resources, lower carbon emissions, and promote efficient recycling of resources.

The construction components include coal preparation, gasification (raw material pretreatment), conversion, low-temperature methanol washing, liquid nitrogen washing, sulfur recovery, ammonia synthesis, air separation, polyols and related utility systems, as well as auxiliary facilities. In which aspects of this construction does it conform to the comprehensive utilization of hazardous waste resources? It’s nothing but a sham, coal chemical projects that take advantage of policy loopholes.
