Solid-To-Liquid Extraction Demonstrator

Solid-To-Liquid Extraction Demonstrator

Description

Solid-to-Liquid

Extraction Demonstrator is equipped with all components required to operate the system. The solvent is stored in a solvent feed tank with an integral heater. Thus, the temperature of the solvent can be varied by manipulating the power to the solvent heater. The solvent is pumped at a constant rate into the extraction column by the solvent feed pump. A flowmeter is included in the solvent feed line. The extrac- tion column is constructed out of glass to allow observation of the extraction process. The solid material is held in a removable retain- er. Sampling ports are included at the inlet and outlet of the extraction column. The process is compatible with a distillation column which allows solvent recovery and/or concentration of the extract. The distillation column includes an electrically- heated boiler with variable power control, a condenser, reflux assembly, and temperature and sampling points to monitor the system per- formance. All points requiring vents are tied together to allow one outlet for removal of sol- vent vapors. All temperatures that need to be monitored are indicated by a digital thermocou- ple display.
