Justification of the Use of Technical Butane for Consumers Gas Supply

Abstract

Nowadays people face lots of problems concerning gas supply especially in those regions, where there is a hostile terrain and the population density is rather poor. There are many individual households and plenty of temporary gas supplied objects, which can’t be gasified with piped natural gas in the future as a result of economic inopportunity. Self-inclusive gas supply systems based on the tank equipment using propane/butane mix can be a solution of this problem. Application of the commercial butane for gas supply requires a detailed research because during the exploitation the contents of this mix change and the share of butane increases heavily. Therefore, we need to explain our technical decisions which can enhance the whole gas supply system if we use butane.The peculiarities of the commercial butane application in gas supply are studied; mathematic simulation methods are used; the peculiarities of commercial butane and soil mass heat change are taken into account; the functional solution for gas supply with the usage of commercial butane is suggested.Recommendations to increase the sufficiency of such gas supply systems are given; the functional solution for gas supply systems using commercial butane is explained and proved, as it provides enough pressure for tank equipment and prevents possible vapour mix condensation in the distribution gas pipelines.In order to provide enough pressure for tank equipment it’s needed to be heat insulated at the access and flange of a tank to avoid heat change with the environment. Commercial butane vapour mixed with the air will let to prevent condensation in the distribution gas pipelines if the restrictions according to Wobbe number variation are taken into account. Functional solutions concerning formation of gas supply system based on commercial butane which can be successfully mixed with air are suggested.
