| The speed of development of natural gas industry is directly determined by the temperament quality Compressed natural gas(CNG).At the present, there is a certain gap of gas quality standards between our country with foreign. As the climate, geographical conditions and etc, the northeast area its quality is lower than the national average standard, the temperament of the desulfurization and dehydration of the compressed natural gas has become an important factor of restricting the development.Whether the process of desulfurization and dehydration and the dehydration index of CNG parent fuelling station is qualified or not, which directly affects the entire gas enterprise whether can run smoothly. One, if the desulfurization index is unqualified which not only causes corrosion on the transport pipeline, equipment, effects on the subsequent processing(such as lead to catalyst poisoning)and the filling vehicles fuel power system with gas terminal, but also sows serious security risks and threats to personal safety; two, the northern winter is cold and long, if the dehydration index is unqualified, the equipment will be frozen blocking situation and seriously impact on the parent station, sub station safety and residential users supply.In this paper, Daqing KunLun Gas Co HongGang parent station is studied, and the process optimization of desulfurization dewatering equipment is completed, the equipment modification, molecular screening, filling ratio, parameter adjustment and other aspects of optimization are carried out, especially the best operating parameters of equipment is realized in cold area of northeast,which ensure the smooth operation and the best benefit of operation equipment.Through the above research, the performance of desulfurization and dehydration and optimization selection of equipment can be understood comprehensively, a theoretical basis and practical reference for the design, construction and operation management of gas station. can be provided... |
