The invention discloses a treatment system and a method applied to MTBE extracted water. The treatment system comprises an extraction column, a cooler, a first feed pump, a second feed pump, a pH adjusting part, a mixer heater and an atomizer. Methanol and a C4 azeotrope are introduced into the extraction column and mixed with extraction water in the extraction column, the mixed extracted water enters the cooler for cooling, after cooling, the first feed pump and the second feed pump are conveyed to the pH adjusting part for pH adjustment, the adjusted extracted water is uniformly mixed in themixer and then introduced into a methanol hydrogen production device or into the heater for heating and heating, and then introduced into the atomizer for atomization after the temperature rise is completed, and then introduced into a dry gas hydrogen production device after the atomization is completed. The invention has the advantages of simple structure, reasonable layout, effective utilization of recovered methanol while reducing cost, considerable economic benefit and good application prospect.
Description
technical field [0001] The invention relates to the technical field of chemical production, in particular to a treatment system and method applied to MTBE extraction water. Background technique [0002] MTBE (methyl tert-butyl ether) is a high-octane chemical raw material used in gasoline additives. It can not only effectively increase the octane number of gasoline, but also improve vehicle performance, reduce CO content in exhaust gas, and reduce Gasoline production costs. [0003] At present, the commonly used method of producing MTBE is to use methanol and isobutylene in C4 as raw materials, synthesized with the aid of an acidic catalyst, unreacted methanol and C4 will be distilled from the azeotrope tower in the form of azeotrope, and then use suitable The extraction water will recover the methanol in the azeotrope, and finally put the extraction water containing methanol into the methanol recovery tower to distill the methanol for recycling as raw material; however, th...
