Study On Process Optimization Of Light Hydrocarbon Storage Device

A natural gas subsidiary company oil gas storage and transport production brigade bright light hydrocarbon main storehouse is one of Daqing ethylene raw material project necessary projects, mainly shoulders the subsidiary company to produce respectively can install produces the light hydrocarbon the storage and the transportation duty, the year storage and transport ability 450,000 tons, is the Daqing Municipal Fire prevention Key Unit. At present, south storehouse transportation's light hydrocarbon for storehouse movement; The bright main storehouse transportation's light hydrocarbon must receive the oil valve group voltage dropping income light hydrocarbon storage tank first, then loses the pump by outside turbo-charged outside to lose. Indicated after the analog computation that optimizes through the technological transformations and the pipe network, the bright main storehouse light hydrocarbon may also realize the storehouse movement, reduces the tube to lose the energy consumption and the light hydrocarbon loses the difference.This article first analyzed and studies Daqing Natural gas Subsidiary company's tube to lose the present situation, after discovering the question, we through calculated repeatedly and profit by opinions from various sources have determined the craft optimization transformation plan. Had determined after above three craft optimization transformation plan, we correspondingly have also worked out a series of craft optimization movement plan in the production movement, guarantees this set of plans the perfect implementation. In fifth chapter in we mainly to implement around the plan the technological parameter to carry on the contrastive analysis, after discovering the implementation plan, the various pipelines' pressure drop universal reduction, the pressure loss reduces. Obtained the following conclusion finally: In the bright light hydrocarbon main storehouse receives the hydrocarbon to collect the tube to lose with outside collects between the tube to add 2 cross lines, may realize the light hydrocarbon long-term Vietnam storehouse movement. North 1-1 deep cold storage tanks and the original steady storage tank add 1 cross line, may reduce the deep Leng Ting saturated vapor tension; Raises outside the plateau steady hydrocarbon to lose pump's inlet pressure.
