Process Systems And Operation Characteristics

A simplified diagram of a process that uses a SCF as a pressure-dependent, variable-power solvent for extraction is shown in Figure 3. A typical system consists of an extraction vessel at high pressure, expansion valves, separator vessels, and a compressor or pump. The feed enters the extraction vessel and contacts the SC C02. The pressure and temperature are controlled. Since its density is high, the SCF dissolves some components and separates them from the feed. The rest is obtained as residue. The SC phase containing dissolved materials flows through an expansion valve where the pressure is reduced. Since its density is reduced, the SCF deposits some dissolved components into the separation vessel as product 1. The re-
