Abstract
A vapor emission control system for preventing the emission to the atmosphere of vapor leaking from a seal of a rotating machine. A containment vessel defines a chamber into which any vapor leaking form the seal must flow. An emission control device is connected to an outlet from the chamber, the emission control device being arranged to render innocuous any vapor delivered thereto through the outlet. Any vapor within the chamber is pumped through the outlet to the emission control device. Thus any vapor leaking into the chamber can only leave the chamber via the emission control device.
