低温甲醇洗操作知识问答（Low temperature methanol washing operation knowledge qa） Low temperature methanol washing operation knowledge qa What is solubility? What is the equilibrium solubility? Solubility refers to the number of grams of solute dissolved in the solute in 100 grams of solvents at a certain temperature. Under a certain temperature and pressure, balance, absorb mass concentration in the vapor-liquid two-phase no longer change, it is the limit of the absorption process, when the balance absorption mass concentration in the liquid phase is called equilibrium solubility. What is the specific content of Henrys law? At a certain temperature, when the gas and liquid phase reach equilibrium, the molar fraction of the soluble gas in the liquid phase is proportional to the equilibrium of the gas in the gas phase, which is Henrys law. The PAE x XA. Where, XA -- the molar fraction of the solute in the liquid phase, PA -- the equilibrium partial pressure of the solute in the gas phase, E -- the proportional constant, called the Henry coefficient. What is raoults law? Under constant temperature pressure, the vapor pressure of the solvent in the dilute solution is equal to the saturated vapor pressure of the pure solvent times the molar fraction of the solvent in the liquid phase. This is raoults law. The mathematical formula is expressed as P1, P10 times X1. Among them, P1 -- the vapor pressure of the solvent in the dilute solution, P10 -- the saturated vapor pressure of the pure solvent at the same temperature, the mole fraction of the solvent in the X1, liquid phase. What is absorption? What is a desorption? Absorption refers to a method of separation in which the solubility of various components of a gas mixture in a solvent is different. Absorption is divided into physical absorption and chemical absorption. The process of removing the acidic gas from the low temperature methanol is the physical absorption. The factors affecting absorption operation are: flow velocity. Gas/
