It has been in This facility was operated without much consideration of the clear operating principle during the operation of the facility because the utility amount was relatively small. Therefore, I have come to conclusion that it is preliminary to understand the principle and output in order to improve the facilities In this study, Aspen plus V10 was used for the process simulation which is operated as the current standard. NRTL-RK model was applied because it is considered the characteristics of fluid. The internal hydraulic analysis of the distillation column was carried out after conducting the normal simulation. also it has been confirmed that the operation can be performed without additional investment even if the production amount of the present invention is increased up to 23% approximately. In addition, the activity coefficient in the infinite diluted state can be estimated, and the possibility of improvement of the gravitational sedimentation type liquid-liquid separator of the high-electric-field type is demonstrated through the development of the operation of the liquid-liquid separator (Decanter) From this study I was able to suggest additional utility savings potential.์ œ 1 ์žฅ ์„œ ๋ก  1 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ ๋ฐฐ๊ฒฝ 1 ์ œ 2 ์ ˆ ๊ด€๋ จ ์‚ฐ์—… ๋™ํ–ฅ 2 ์ œ 2 ์žฅ ์—ฐ๊ตฌ ๊ณต์ • 5 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ ๊ณต์ • 5 1. ์—ผํ™”๋ฉ”ํ‹ธ๋ Œ/ํด๋กœ๋กœํผ ์ œ์กฐ๊ณต์ • 5 2. ์„ธ์ฒ™ ๋ฐ ์ •์ œ ๊ณต์ • 8 ์ œ 2 ์ ˆ Karl Fischer ์ „๋Ÿ‰ ์ ์ •๋ฒ• 11 ์ œ 3 ์žฅ ์—ด์—ญํ•™์  ๋ชจ๋ธ 13 ์ œ 1 ์ ˆ NRTL-RK 17 ์ œ 2 ์ ˆ ์•„์ œ์˜คํŠธ๋กœํ”ฝ ์ฆ๋ฅ˜ (๊ณต๋น„์ฆ๋ฅ˜) 19 ์ œ 3 ์ ˆ Infinite-dilution activity coefficient. 25 ์ œ 4 ์žฅ ์‹คํ—˜ (๊ณต์ • ๋ชจ์‚ฌ) 26 ์ œ 1 ์ ˆ ์ •์ƒ์ƒํƒœ ๋ชจ์‚ฌ 26 ์ œ 2 ์ ˆ Process ๋ชจ์‚ฌ ๊ฒฐ๊ณผ 34 1.
