N-butane gas price

N-butane gas price

The general uses of n-butane in China are civil combustion and industrial raw materials. In terms of industrial use, high purity butane is used as maleic anhydride and n-butane isomerization routes. Maleic anhydride has been mentioned in the previous article, the profit is high, but it has not played a role in boosting the raw material butane. In terms of isomerization, it is mainly used as the upstream device of the dehydrogenation unit to meet the raw material production of the terminal MTBE. According to Zhuo Chuang information statistics, more than 90% of dehydrogenation plants are equipped with n-butane isomerization devices. Regardless of the profit situation, the procurement of n-butane in the downstream of dehydrogenation is rare, and self-sufficiency is the main trend in the current light performance of terminal M. Therefore, the influence of isomerization on n-butane exists, but the strength is limited.

How much does helium cost a bottle now

How much does helium cost a bottle now

Aerospace field. Uses: In rocket and space vehicle fuel systems, helium is used for cleaning cryogenic fuel and oxidation tanks, as well as pressurizing the surface space of cryogenic tanks to provide pressure for direct delivery of liquid hydrogen and liquid oxygen or to provide only a net suction positive pressure to infusion pumps. Helium is often used as a working medium in pneumatic control systems. Prior to rocket launch, cryogenic helium has been used to pre-cool upper stage liquid hydrogen rocket engines for maximum propulsion efficiency in the first few minutes of ignition. Liquid helium is also widely used in cryogenic radiation detectors and for other specialized instruments in space exploration programs.
