5.1 General Description
5.1.1 The function of the Reprocessing Unit is to add oxygen to restore the gas mixture then
scrub the recovered gas to remove CO 2 and other contaminants. Its operation can be broken
down into two sections.
5.1.2 The Inlet Section consists of a moisture separator and float valve to prevent water
being passed into the reprocessing unit, an oxygen injection point and two receivers which
primarily smooth out fluctuations in the flow to the Electrical Gas Booster.
5.1.3 The Outlet Section Gas is discharged to this section from the Electric Gas Booster
outlet. It consists of further filtration to remove water particles and any other solid material.
Chemical scrubbing is also employed to remove carbon dioxide and other trace contaminants.
5.1.4 The operation and layout of each of these sections is described in the following.
