Detection of Leak Position in Household LPG Distribution Pipes Using Gas Pressure Sensors and Continuity Equation

Abstract

Factors causing pollution both water and air and fires can be caused by the pollution of liquefied petroleum gas (LPG) that comes from gas network leaks from National gas Company (PGN) to households. For National gas Company (PGN) due to LPG gas pipeline leaks can cause quantitative losses. To prevent losses caused by LPG network leaks that are distributed to households, a gas pipeline leak detection system can be applied using the concept of fluid mechanics. Where the position of the gas pipe leakage can be known by the difference in gas pressure at the two ends of the pipe. The difference in pressure on the small gas pipe after the calculation by including the friction factor then the pipe has a leak, but if the difference is greater then the pipe is in normal condition. To detect leaks quickly, the pressure monitoring data will be monitored in a database that is displayed in front end point of the location of leakage of household gas pipes to officers who monitor the performance of the household gas pipeline. The results of this study indicate that the distance or position of the gas leak in the gas pipeline network can be measured by the difference between the two pressures at both ends of the gas pipe that is leaking. The error resulting from the reading of the pressure sensor which produces the calculated distance value to the measurement result of the actual distance of the gas leak position in the pipeline is 0.63% which shows the results of this study are very good.
