November 27, Zhenhai Refining and Refinery two innovative ideas using new methods successfully reuse EO / EG plant waste ammonia, the method effectively eliminate environmental pollution, the output of qualified liquid ammonia, to achieve a win-win environmental economics.
Due to improper disposal of waste ammonia generated from ammonia compressor overhaul of ethylene EO / EG unit, it will cause environmental pollution, meanwhile there is a risk of leakage of ammonia during the transfer process, and the waste ammonia water in the temporary pipeline can not be replaced easily Resulting in environmental pollution.In response, the two take the initiative to take the task of waste ammonia wastewater treatment, combined with previous experience, to avoid environmental risks innovative ideas, the use of new methods to reuse EO / EG waste ammonia, that is, both ends of the temporary pipeline with valves, In the end of the dumping to the line of clear water and the entire process of ammonia transfer in the whole process of analysis, in advance of the transfer of ammonia wastewater control operations and docking with the tanker transport unit ammonia solution plan, a clear leak treatment plan. In the course of operation, we arrange special guardianship and strictly implement the safety control of direct operation. After the operation, we strengthen the equipment stare list to avoid abnormal fluctuations of the device due to the change of the nature of the raw materials.
It is reported that as of the end of November, Ⅰ stripping device safely and smoothly completed the receiving of 40 tons of waste ammonia; fine operation of the device at the same time, to achieve a smooth waste ammonia 'digestion'.
