System Overview

Reactor Assembly

Manifold Control Valves

Each side of the reactor assembly contains two manifold control valves: Control Valve

(on left) and Control Valve

(on right).

Utility

Control Valve 1 can allow either solvent or drain gas (30 psi) into the corresponding

upper manifold common pathway.

Control Valve

can be set to Vent, used during solvent addition, or it can be set to

"Metered Gas" which introduces 10 psi gas into the corresponding upper manifold

common pathway. Metered Gas is used primarily to provide an inert atmosphere to the

RVs and to provide a lower pressure drain gas for product collection into vials. The

flow rate of the metered gas can be controlled via a needle valve located at the top of

the Quest unit.

The manifold control valves are set in conjunction with each other to create various

fluidic paths.

Some possible settings are as follows:

Solvent Delivery.-

Creates a flow path to deliver solvent from the

external

bottle, in parallel to the bank of 10 RVs.

Solvent Line Flush

Creates a path for gas at 30 psi to flow through

the manifold after a solvent delivery to blow the residual solvent into

the RVs.

Vessel

Draining

Supplies

psi gas to the upper manifold common

path, pressurizing the upper RV head space for draining of waste

liquid to the glass waste tank.
