Abstract
กรรมวิธีถูกบรรยายสำหรับผลิตพอลิคาร์บอเนท และใช้อย่างนอยบางส่วนของ น้ำเสียของกรรมวิธีโดยนำวัฏภาคน้ำเสียที่มีโซเดียม คลอโรด์มาทำให้เข้มข้น สำหรับอิเล็กโทรไลซิสโดยใช้การกลั่นแบบออสโมติค เมมเบรน, ถ้าเหมาะสมด้วยการเจือจางใน เวลาเดียวกันของสารละลายโซเดียม ไฮดรอกไซด์ที่ทำให้ได้จากอิเล็คโทรไลซิสสำหรับกรรมวิธี การผลิตพอลิคาร์บอเนท The process is described for producing polycarbonate. And use at least some of Wastewater of the process by using the sodium-containing wastewater process Chloride to concentrate For electrolysis using membrane osmotic distillation, if appropriate by dilution in The same time of sodium solution Hydroxides obtained from electrolysis for processing Polycarbonate production
