Dimethyl ether detection in liquefied gas
Dimethyl ether is a new type of green environmental protection energy. Its performance is similar to that of liquefied petroleum gas. It is a new type of clean fuel for the substitutive generation of petroleum products. It contains oxygen, a single component, a short carbon chain, good combustion performance, and high thermal efficiency. There is no residual liquid and no black smoke during the process. It is a good, clean fuel. The experimental data shows that the ratio of latent generation to liquefied gas is 1:1 when the ratio of liquefied gas is not more than 25%. To strictly control the proportion of mixed, the autumn and winter season is 1:5 or 1:6, the spring and summer season is 1:4 or 1:3.
The incorporation of dimethyl ether into the liquefied gas enables the combustion of the liquefied gas to be more complete, enabling the residual liquid to be carried out, reducing the possibility of carbon deposition, and reducing the CO and hydrocarbon content in the exhaust gas; in addition, dimethyl ether can also be used. The incorporation of city gas and natural gas in mixed combustion can solve the problem of insufficient gas volume at the peak of city gas, and at the same time improve the gas quality and raise the calorific value.
China Science Spectroscopic Instrument Co., Ltd. has introduced equipment and supporting methods for separating and calculating the content of dimethyl ether in liquefied gas. Currently, most of the liquefied gas in the market is blended with dimethyl ether. Want to know what percentage of liquefied gas components? Is there dimethyl ether in liquefied gas? How much dimethyl ether? In liquefied gas, I want to add dimethyl ether. What is the content after blending? How much is the purity of purchased raw material dimethyl ether?
II. Methodology LPG analysis includes analysis of liquefied gas components and analysis of dimethyl ether and methanol in liquefied gas, excluding alkynes, gas chromatograph with thermal conductivity detector, and various groups of samples in the column. Separation, area normalization method or calibration area normalization method, external standard method to quantify the percentage of each component.
