Scheme Research And Engineering Design Of Vehicle-mounted Venting Gas Recovering Unit Using ANG Technology

Aiming at the facing problems of emission of pipeline natural gas recovery and emergency supply to downstream users,in this paper,for the fisrt time,the study and application of natural gas adsorption storage and transportation technology are compared and analyzed,on the other hand,we have discussed on the design requirements of vehicle ANG emission gas recovery device and the applicable scope.It is concluded that the ANG storage and transportation process would be popularized in vehicle technology.Secondly,we have researched on the natural gas in Foshan in a certain area of anfemission research,it shows that the gas emission in the region is adptable to get recovered,and it’s with the environmental and economic doubble benefits.According to the ANG and process design of vehicle ANG emission gas recycling program,and designed experimental routes which are required in engineering testing,and Engineering Research of ANG vehicle emission gas recovery device.The main parameters of key equipment design of ANG storage tank are:the ANG tank’s total volume of is 2.20m3 with the diameter of 1400 mm and the height is 1971.5mm;On the oter hand the tank has two main sides of each fand,two manhole with each other,two hand holes are respectively arranged on the tank body symmetry,adsorption tank built-in support plate,ANG pre-adsorption tank volume is 0.22m3,screen structure.Two kinds of activated carbon were used to fill up the cylindrical shaped activated carbon in order to fill the pre adsorption tank.Finally,according to the actual situation of the project,the design of the process and the device is optimized,Engineering research results are followings: we have the ANG tank further improved and increase the size,instead of two ANG tanks with same volume capacity of 2.2m3,parallel storage capacity,the storage capacity is estimated to reach 365.2Nm3,and reached 241032Nm3 to calculate the recovery rate;the total investment has reached 2 million 400 thousand yuan,the annual income of 856 thousand yuan,the annual operating cost of 290 thousand yuan,the payback period is 4.24 years,with a good economy.The design of the whole vehicle ANG exhaust gas recovery device for the application and emission of gas recovery and subsequent ANG emergency supply provides a new thinking and new method is feasible,has great realistical significance,It will play an important role in promoting the development of ANG technology and natural gas industry in the future.
