Oil Associated Gas Recycling Purification System

Most of our oil fields are found associated gas resources, has adopted oil associated gas purification recovery technology, due to geographical constraints of the small number of scattered field of the associated gas burned each year about 1000 million m³, which is equivalent to one million tons oil. With the further development of the landlocked oil fields, an increasing large of associated gas has been wasted, so there was a need to research a new technology system method for the associated gas recovery and utilization in remote areas.HYSYS chemical process simulation accuracy and precision, not only for the improvement of process design, but also production guidance of great significance in reducing the experimental consumption, and eliminate security risks is also very necessary. HYSYS is the most widely used simulation software of one chemical, it is simple, powerful, and accurate simulation of the advantages of simulation of complex chemical process is an important tool.In this paper, Using HYSYS simulation software simulate the new technology of oil associated gas system,, the whole process can make a correct assessment of the future through the simulation results would be applied to the whole process works in practice to lay a theoretical foundation and could provide a help. In accordance with the needs of the overall system design, based on the recovery of oil associated gas purification process conditions, but due to time constraints of the spiral roll separator membrane had a rough design and draw a spiral roll separator membrane structure of Fig.In order to further study the oil associated gas purification effects of recycling, paper recycling purification process of the impact of important factors under different conditions, including pressure, temperature and other factors have been studied and some useful results:(1) The volume of exports of H₂S with the increase pressure in penetration side infiltration generally increases linearly.(2) The higher gas pressure, export H₂S mole fraction lower than the pressure in the permeate side 3MPa around, the impact is not significant.(3) In certain circumstances the temperatures of the infiltration of H₂S with the flow of permeate side pressure lowered.Finally, dynamic process, based on the steady-state, based on factors that make a certain amount of study and the conclusion of the growth over time, by controlling the number of conditions (such as pressure, etc.) can achieve a stable recovery results.
