In the liquefied gas market, in addition to traditional blending varieties such as dimethyl ether and methanol, the phenomenon of blending methylal has recently surfaced. The blending areas are mostly concentrated in Henan and along the Yangtze River. The phenomenon of illegal operators using non-hazardous transport vehicles without any safety protection measures to transport bottled liquefied gas is serious. Illegal business activities such as adding extremely dangerous dimethyl ether and methylal to bottled liquefied gas also occur from time to time. If the blending ratio of liquefied gas is less than methylal, the combustibility can be improved. If the blending ratio exceeds, the combustion performance of the liquefied gas will be reduced, which will be manifested as a smaller flame, residual night, and corrosion to cylinders, stoves, etc. effect.
Our company has successfully developed a gas chromatograph for methylal in liquefied gas. Long-term tests have shown that the special chromatograph for methylal in liquefied gas has accurate results, is easy to use, and has a high degree of automation. Completely separate methylal and other components in liquefied gas. Accurate characterization and quantification can be achieved.
