Factory of daqing petrochemical company chemical raw materials, the author of this paper 2 tank storage and transportation facilities reconstruction project in new saturated hydrocarbon storage tank and accessory storage and transportation facilities to carry on the design and research, make its have the function that receive the refined raw material.Design research and completed the process of storage tank, the selection of main equipment, pipelines, selection of coatings. Winter tank unloading compressor, due to the compressor inlet air supplement, carburetor(non skid) available light hydrocarbon, smelting the liquid inside the spherical tank, the spherical tank within the medium temperature from-20 ℃ to 15 ℃, improve the saturated vapor pressure tank, make it satisfy the requirement of the compressor inlet suction volume, implement tank compressor operation in winter. |
