| titleOfInvention | Method and system for feeding steam from drying column into column for light fractions |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of producing acetic acid by carbonylation, which includes steps of purifying a crude product stream in a column for light fractions to obtain a product stream; feeding the product stream into a drying column to obtain a dry product stream and one or more steam side streams, where the one or more steam side streams provide energy to one or more separation systems. The invention also relates to a method of producing acetic acid by carbonylation, which includes steps of purifying a crude product stream in a column for light fractions to remove methyl iodide and methyl acetate and obtain a product stream; the product stream having lower concentration of methyl iodide and methyl acetate than the crude product stream; removing the product stream from the side portion of the column for light fractions and feeding the product stream into a drying column to obtain a dry product stream and one or more steam side streams, where the one or more steam sides streams from the drying column heat the product stream in the column for light fractions. n EFFECT: methods relate to improving the overall efficiency of the process by providing energy needed to perform separation in a separation system. n 22 cl, 1 dwg, 7 ex |
