The Study And Development Of Skid-mounted Natural Gas Processing Unit

The natural gas engine gains an advantage of the cheap fuel and low let over other engines, so it is utilized universally in the field of petroleum and natural gas. But the quality of fuel is required rigidly for the natural gas engine, which limits its application, especially at the small and outlying regions. The quality of natural gas doesn't satisfy the running need of lasting, stabilization and high efficient because the processing technic is not prefect and the quality of fuel is bad, so the natural gas must be processed multilevel.At the first, the key problems were investigated systemically during the process of dealing with natural gas in this paper, which conclude: the calculation of containing moisture quantity in the nature gas, the natural gas-purifying, the recovery of hydrocarbons, the processing course of low temperature and the drew point-controlled of natural gas. Then, skid mounted processing unit of natural gas was developed according to the components and the especial requirement of natural gas, focused on the YH1 transition oil station as the experiment unit. The equipment is suitable to utilize at the outlying regions.The skid mounted processing unit of natural gas was developed by the scheme of low temperature, condensation and dryness. The advantages of the scheme are low investment, simply manipulation, small volume, and liable to skid mounted. The cost of designing and producing decreases with the scale of manufacture. The characteristics of the equipment are the simpleness of flow, the reasonability of refrigeration fashion, the choice of energy-saving equipments, the security and credibility of equipments-running, the simplenese and applicability of auto- controlled instruments, Skid mounted unit and the smallness of occupied area. The disposal ability of natural gas, the quality and yield of product mounted to the design index, meanwhile, and gain the outstanding the economical efficient and social efficient.There are abundant natural gas resources in our country, but these resources have not been exploited by the effective method. The skid mounted processing unit of natural gas is very essential and feasible. It will meet the needs of the quality of natural gas in the produce of oil field and living to extend the natural gas engine at the outlying regions, which attain the purpose of conserving cost, decreasing theenergy-consuming and so on.
