Technology and Safety Evaluation of Qinghai Province's Key Project: Comprehensive Utilization of Main Products and Accessory Products of Megaton Potassium Chloride

It is very important for developing circular economy to comprehensively utilize salt lakes, crude oil and natural gas resources in Qinghai province. The key project of comprehensive utilization of mainproducts and accessory products of megaton potassium chloride is being fulfilled by Qinghai salt lake potash Co. Ltd. The raw and processed materials, obtained from inorganic compounds of salt lakes, crude oil and natural gas, will be utilized effectively in the project. The products include potassium hydroxide, potassium carbonate, chloroethylene, polyvinylchloride, ammonia and carbamide. The technology and safety condition of the project are analyzed in the paper. The harm or hazard from the existent production enviromerit,and the aftereffect are also discussed. In order to achieve inherent safety and production safety,some measures have been put into action in all areas of the project and a series of countermeasures havebeen put forward to avoid possibe accidents.
