Method and system for recycling by-product hydrogen chloride in fatty acid or fatty acyl chloride chlorination production process

The invention discloses a method for recycling the by-product hydrogen chloride in the fatty acid or fatty acyl chloride chlorination production process. The method includes the steps that the by-product hydrogen chloride waste gas generated in a chlorination reaction of fatty acid or acyl chloride thereof is introduced into a hydrogen chloride purification tower from the lower portion of the hydrogen chloride purification tower and makes countercurrent contact with absorption liquid in the hydrogen chloride purification tower, and organic impurities in the hydrogen chloride waste gas are adsorbed and removed with the absorption liquid; the hydrogen chloride waste gas obtained after absorption purification and oxygen are subjected to a catalytic oxidation reaction under the action of an oxidation catalyst; mixed gas obtained after the oxidation reaction of hydrogen chloride passes through chilled brine, and the mixed gas obtained after chilled dehydration is subjected to catalytic chlorination with fresh chlorine and fatty acid or acyl chloride thereof directly so as to produce chlorinated aromatic hydrocarbons; the hydrogen chloride waste gas containing organic impurities enters the hydrogen chloride purification tower from the lower portion of the hydrogen chloride purification tower to be subjected to absorption purification again. By means of the method, the tedious processes of conducting compression chilling and the like for separating oxygen after hydrogen chloride is oxidized are omitted, the technological route is shortened, and the equipment investment cost can be greatly reduced.

Anti-seepage vacuum insulation outer wall facing tile

InactiveCN103410283AImprove smoothnessEliminate local hollowingCovering/liningsBrickThermal insulation
The invention relates to building materials in the building energy-saving waterproof field, in particular to an anti-seepage vacuum insulation outer wall facing tile. According to the anti-seepage vacuum insulation outer wall facing tile, a flat face brick is additionally arranged on the basis of the technology of 'anti-seepage insulation facing tile' with the application number of 201210074941.0, and meanwhile a vacuum chamber is additionally formed in a brick body. The top end of a paved facing tile presses against the lower portion of a lower end water dripping olecranon-shaped mouth, and a left side tile tenon right falls in a right side falling groove, so that the facing tiles can be covered by one another, joint seams among the facing tiles will not be exposed outside, and rain can be prevented from entering a wall body from the joint seams. Due to the facts that the seams among the facing tiles are not squeezed any more when the facing tiles are paved, and the seams are not scraped outwardly any more after the facing tiles are paved, when temperature rises or falls, gaps for allowing the facing tiles to stretch out and draw back exist when the facing tiles are in the condition of expanding with heat and contracting with cold, and therefore local hollowing caused by squeezing of expanding with heat and contracting with cold can be avoided. In addition, air holes and the vacuum chamber are formed in each facing tile body, so that not only is the range of expanding with heat and contracting with cold of the outer wall facing tile reduced, but also the coefficient of heat conductivity of the outer wall facing tile is greatly reduced. Therefore, the purpose of thermal insulation is achieved.
