Pinch Analysis - Case II
Desmet / Hytech
Air Pre-heating with Vapors from Mineral and Edible Oil Strippers
Takes advantage of 70 - 100% of the water vapors from mineral and edible oil strippers.
Air Preheating from 30ºC (86ºF) to 60ºC (140ºF) in summer and from 0ºC (32ºF) to 45ºC (113ºF) in winter.
Steam saving: 9 to 13 Kg per Ton (18-26 lbs/t) of soybean.
