Study On Liquefaction And Transportation Technology Of Carbon Dioxide

CO₂ emission has been paid more and more importance with the increase of the global temperature. Every country in the world is trying its best to bury and store CO₂ or enhance the oil recovery with CO₂ so that the CO₂ emission can be reduced. In this paper, the simulation and calculation of physics property of CO₂, liquefaction of CO₂, transportation of CO₂ is mainly done.First, simulation and calculation of physical properties of CO₂ is done with software HYSYS.Second, the simulation and calculation of liquefaction of pure CO₂, CO₂ with the impurity CH₄, CO₂ with the impurity N₂ will be made respectively in the condition of high pressure and in the condition of low temperature with HYSYS. Work deplete will be compared and analyzed in the conditions of different liquefaction pressure and impurities'effect on liquefaction with HYSYS. And the simulation and calculation of CO₂ separated from the orient 1-1gas field will be done with HYSYS.Another, the simulation and calculation of pure CO₂, CO₂ with impurity CH₄ and CO₂ with impurity N₂ will be made respectively in the condition of liquid and isothermal state, in the condition of liquid and non-isothermal state, in the condition of supercritical state and in the condition of compact phase state, and meanwhile analyze some factors'effect on the drop of pressure such as the length of pipeline, rate of flow, pipe diameter and angle of depression of pipeline and so on. Analyze the impurities'effect on drop of pressure such as CH₄ and N₂.The simulation and calculation of physical property of carbon dioxide has been completed; the simulation and calculation of work deplete has been completed in different conditions; the simulation and calculation of CO₂ separated from orient 1-1 gas field has been completed; the simulation and calculation of transportation of CO₂ in different conditions has been completed ; the effect of the different parameters on transportation of CO₂ has been analysed.
