Point supply LNG detection analyzer

Point supply LNG detection analyzerApplication:

Point supply "gas includes liquefied natural gas (LNG) and liquefied petroleum gas (LPG), where LNG is supplied by low-temperature stainless steel cylinder groups through gasifiers, and LPG is supplied by liquefied petroleum gas cylinder groups through gasifiers. Transported by truck to the gas factory, then unloaded and loaded with low-temperature stainless steel bottles or petroleum gas cylinders, and transported to the factory's self built gasification station for gasification, providing independent point-to-point gas supply to users. Due to the low cost and the strong promotion of the "coal to gas" policy, enterprises have focused on cost considerations, resulting in a high concentration of LNG supply projects in many regions. But mixing nitrogen during transportation to reduce costs and earn profit from price differences,The quality components and combustion values of the gas supply source at the testing point only need to be checked for nitrogen content.

Principle:

Component analysis: Use chromatographic separation method to complete the work. Due to the different components of the mixed gas, the length of time it stays in the chromatographic separation column varies, and the separation sequence is based on the order of gas weight from light to heavy. So this way, a detection instrument can be used to separate different gas components over time. By the order in which gas components are separated, we can know the names of various components in the mixed gas. Gas chromatograph for natural gas analysis, equipped with a two-stage pressure stabilization system, a six way valve injection system for packed columns, a thermal conductivity detector, and a gas analysis chromatographic workstation; It can achieve full analysis of hydrocarbon components such as oxygen, nitrogen, methane, ethane, carbon dioxide, propane, isobutane, n-butane, n-pentane, isopentane, and C6+in natural gas with a single injection.
