Problems solved by technology
[0003] The existing technology vaporizes specific components in liquefied petroleum gas and passes them into a chromatographic analyzer for detection. However, the sample source, the gasification junction, and the chromatographic analyzer are usually connected horizontally, and the flow characteristics of liquid and gas are not fully utilized. A certain external force pushes or the process is not smooth

The invention relates to a method for rapidly detecting liquefied petroleum gas components. The method is characterized by comprising the following steps: (1) a sample source of liquefied petroleum gas is communicated to a liquid inlet of a gasification structure, wherein the liquid inlet is formed in the upper end of the gasification structure; (2) a liquefied sample declines from the sample source to enter the gasification structure to be converted to gas; (3) the gas-state sample rises to enter a chromatographic analyzer communicated to gas outlets from the gas outlets to be detected. According to the method for detecting, the liquid inlet and the gas outlets of the gasification structure are formed in the top end separately, and the characteristic that liquid falls down by depending on the gravity per se and gas moves upwards is fully utilized, so that the smooth whole detection process is facilitated.
Description
technical field [0001] The invention relates to a method for detecting components of liquefied petroleum gas. Background technique [0002] With the development of petrochemical industry, liquefied petroleum gas has been paid more and more attention as a basic chemical raw material and new fuel. In terms of chemical production, liquefied petroleum gas is a by-product obtained during the catalytic cracking and thermal cracking of crude oil in refineries. It can be used to produce synthetic plastics, synthetic rubber, synthetic fibers and produce medicines, explosives, dyes and other products. Using liquefied petroleum gas as fuel, because of its high calorific value, no smoke, no carbon residue, easy operation and use, has widely entered the field of people's lives. In addition, liquefied petroleum gas is also used for cutting metals, baking agricultural products and roasting industrial kilns, etc. [0003] The existing technology vaporizes specific components in liquefied...
