Study Of Effective Radius About CNG Supply

In the wake of natural gas age advent,The technique of Compress Natural Gas (Abbreviation CNG ) about our country has become fully mature and completely home-made.Compress Natural Gas except for is used the motor vehicle fuel, still widely is used inhabitant in cities and towns. In the supply process of Compress Natural Gas, there are some problems effect the economy of it, for example: the type of compressor in gas entrainment stop is not rightful; The ratio of equipment be utilized is low;The equipment and dispatch of transportation tank wagon is not rightful,and the transportation expense is high;The scale economy radius is not decided.All this greatly conditioned the wide-ranging use of Compress Natural Gas.This dissertation researched is: to decide the scale of Compress Natural Gas supply;By means of analyzing the technique and economy about different supply gas means; Being living to compress the natural gas matter runs on the oil painting base;Establishment mathematical model,Fix to compress the economic radius of natural gas. The main research contents possess :1 .Making a technical and economical analysis between CNG,LNG,LPG,LPG with air and pipe nature gas, then to fix the economic scale of CNG to be used to cities and towns is 2000 doors to 50000 doors.2.Evaluation of the schemes' superior and inferior through means of the parameter about achieving economical scale,the electric consumption about unit economy amount of gas,the adaptiveness about working,economy about investment, then to decide the scale and amount of compressor under the different supply gas scale.3.Establishing mathematical model about van truck' optimization and dispatch with heuristic algorithm of various model and full load vehicle, and optimizing the truck type using to different supply gas scale. 4.Establishing mathematical modelabout effective radius, then to decide the effective radius of different supply gas scales.All of this in order to supply reference for the consumers who use nature gas as gas source and fuel gas of motor vehicle.
