Apparatus for separating paraffin from oil in refineries wherein such separation is accomplished by a cooling process, in a heat exchanger, the apparatus controlling the cooling process by sensing either the pressure upstream of the heat exchanger and directly controlling the flow through a heat exchanger bypass, or sensing the temperature downstream of the heat exchanger and inversely controlling the flow through a heat exchanger bypass, the flow control in each case regulating the flow of cooling liquid through the heat exchanger. |
