method – Wacker process
현재 흔히 이용되고 있는 Wacker process 방법은 ethylene의 부분 산화 반응으로 아래와 같은 반응식을 따른다.
C2H4+2CaCl2+H2O -> CH3CHO+2HCl+2CaCl2
2CaCl2+2HCl+1/2O2 -> 2CaCl2+H2O
반응물로 이용되는 ethylene은 원료비가 비싸고, 공정 과정에서 반응기 부
Throughput time = 30min
Process velocity = 30/
Cycle time = 10min
Capacity = 6unit/hr
Utilization = ① 10/10 = 1 ② 7/10
③ 1/10 ④ 5/10
⑤ 5/11 ⑥ 2/11
① The weight scale tests = 10 min ② weigh and record each bucket
= 7 min x 300 buckets = 2100 min ③ time to wrap each roll = 9000 Roll / 20 Roll =
