Abstract
วิธีการที่ได้รับการปรับปรุงให้ดียิ่งขึ้นของการผลิตกรดแอซีติกประกอบด้วยการควบแน่นไอ ส่วนบนจากคอลัมน์ส่วนกลั่นเบาสู่เฟสเบา และเฟสหนัก โดยส่วนใหญ่แล้ว เฟสหนักประกอบด้วย เมธิลไอโอไดด์ และอย่างน้อยที่สุดส่วนหนึ่งของเฟสหนักที่เทได้รับการกลั่นไหลกลับสู่คอลัมน์ส่วน กลั่นเบา ทั้งปริมาตรกรดแอซีติกของกระแสส่วนบนคอลัมน์ส่วนกลั่นเบา และปริมาณน้ำในกระแส ผลิตภัณฑ์ (ส่วนดึงด้านข้าง) ของคอลัมน์ส่วนกลั่นเบาจะลดลงซึ่งเป็นการปรับปรุง ประสิทธิผลของการทำให้บริสุทธิ์ที่ดียิ่งขึ้น Improved methods of acetic acid production include vapor condensation. The upper part from the light column to the light phase and the heavy phase. Heavy phase consists of Methyl iodide And at least part of the heavy phase being distilled is returned to the light distillation column, the entire acetic acid volume of the upper current, the light distillation column. And the water content in the product stream (side draws) of the light distillation column is reduced, which is an improvement The effectiveness of the better purification
