haohan毛细管柱测定液氨中的甲醇HH-PLOT-Q

          煤炭气化、变换、粗煤气的净化、甲醇合成是煤制甲醇工艺的主要步骤。煤炭气化指将固态的煤在一定条件下转变为气态的过程,而转变后的气态条件下,即粗煤气中不仅含有一氧化碳、氢气等有效气外,还含有一定量的二氧化碳、硫化氢等杂质气体。为了回收其中的有效气,必须脱除杂质气体,即脱硫脱碳。煤气净化的工艺有很多,比较常见的有低温甲醇洗、MEA法、NHD法等,其中低温甲醇洗相比其他一些方法,在-些大型的化工工业装置中优势更加明显,它的吸收原理为物理吸收,如今国内一些合成氨厂、化肥厂和甲醇厂投资兴建了多个低温甲醇洗项目。 低温甲醇洗工艺根据低温下不同气体在甲醇中溶解度的不同,脱除其中的酸性气体,而保留了有效气体,达到分离净化原料气的目的。

Coal gasification, conversion, crude gas purification, and methanol synthesis are the main steps of the coal-to-methanol process. Coal gasification refers to the process of transforming solid coal into a gaseous state under certain conditions, and under transformed gaseous conditions, that is, crude gas contains not only effective gases such as carbon monoxide and hydrogen, but also a certain amount of carbon dioxide and hydrogen sulfide Impurity gas. In order to recover the effective gas, the impurity gas must be removed, that is, desulfurization and decarbonization. There are many processes for gas purification.The more common ones are low temperature methanol washing, MEA method, NHD method, etc.Compared with other methods, low temperature methanol washing has more obvious advantages in some large chemical industrial units. Its absorption principle is Physical absorption. Nowadays, some domestic ammonia plants, fertilizer plants and methanol plants have invested in constructing multiple low temperature methanol washing projects. The low-temperature methanol washing process removes the acidic gases according to the different solubility of different gases in methanol at low temperature, and retains the effective gas to achieve the purpose of separating and purifying the raw material gas.

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. uses gas chromatography to determine methanol in liquid ammonia. It is fast, simple and highly accurate.
