Motalo A. Methodology of quality evaluation of natural gas as a energy carrier

Dissertation is devoted the decision of actual tasks of qualimetry of natural gas, in particular, to development of methodology of evaluation of quality of natural gas as a power medium, that is the purpose of dissertation work. For achievement of this purpose the followings tasks were formulated and untied: the indexes of quality of natural gas are systematized after the groups of him functional setting and optimum composition of indexes is set gas qualities which have a determining influence on his quality as a power medium; theoretical principles of construction of the system of evaluation of quality and accordance of natural gas are developed as a power medium and methodology of its construction is developed; the method of construction of virtual measure of quality of natural gas as a power medium is developed and construction of it on the basis of base type of gas quality; the method of complex evaluation of quality and accordance of natural gas as a power medium is developed with the use of virtual measure of quality of gas and self-weighted Euclidean model of individual differences; experimental researches of tests of natural gas are conducted the level of its quality as a power medium is certain after the method developed in dissertation work.
