It is defined as in the following example: O = Once through liquid system P = Partial recirculation liquid system T = Total recirculation liquid system (plate heat exchanger) S = Total recirculation liquid system (shell and tube exchanger) K = Cast iron construction / 316 stainless steel M = 316 stainless steel throughout... -
Page 9: Total Recovery (Closed Circuit)
Product Description | 2 2.4.2 Partial Recovery (Open Circuit) Approximately 50% of the operating liquid is recirculated within the system whilst addi- tional liquid is added via the fresh liquid line to maintain the liquid temperature. The pro- cess gas and operating liquid are discharged from the vacuum pump together into the separator vessel (SV) where they are separated. -
