chemical separation process system, distillation column arrangement and chemical separation method

摘要

Summary "Chemical separating process system, distillation column arrangement and method for separating chemicals" is a chemical separating arrangement comprising a first distillation column (100) and a first distillation column ( 100) receives a mixture comprising water and at least two organic acids and extractant comprising at least one of the following: hexanol, a hexanol ester with said at least one organic acid and 2-methylpentanol. the first distillation column (100) forms a heterogeneous water and top extractant azeotrope (104) based on reactive heteroazeotropic extractive distillation that does not control chemical reactions between the extractant and said at least two organic acids, wherein said first distillation column (100) removes the azeotrope through its top (104) to separate water from organic acid; 1/1
