DEVELOPMENT OF NEW METHODS FOR DETECTION OF LEAKS OF HYDROCARBON GAS
(с. 60-64)

Abstract. The paper is devoted to development of new methods for detection of leaks of hydrocarbon gas. It is determined that the wellknown fact on inverse interrelation of concentration of oxygen and such gases as N2 and CH4 can be used for remote determination of leaks of hydrocarbon gases. The gradient method for detection of leaks of natural gas composed of determination of two directions with minimum value of gradient of concentration of O2 in two fixed points and characterization of the point of crossing of them as a site of leak is suggested. The method of circles for detection of natural gases leaks site providing for determination of three points in supposed zone of leak and drawing up the circles around these points with growing radius with defined regularity is suggested. The point of crossing of all circles in some cycle of radiuses increase is presented as the gas leaks site. The carried out experimental researches held in various amounts of wind speed shown that when the wind speed surpass the fixed value location of gas leak site would be impossible due to effect of wind on spatial distribution and concentration of natural gas. Thus the proposed method is not designated for cases when a heavy wind occurs.

Keywords: hydrocarbon gas, leaks, regression, gradients method, method of circles.
