Abstract

A system for processing vapor. The system includes a vapor source for producing a vapor and an outlet conduit coupled to the vapor source for carrying the vapor from the vapor source. Downstream of the vapor source the outlet conduit separates into a vapor bypass conduit and a vapor feed conduit. The system further includes a first vapor control valve disposed in the bypass conduit, a second vapor control valve disposed in the feed conduit, a first vacuum chamber connected to the bypass conduit, and a second vacuum chamber connected to the feed conduit.
