ABSTRACT:
An improved purging process in which purge gas is flowed through a flare system at a sufficient flow rate to minimize or at least acceptably control the rate of back flow of air migration into the exit port of the system. The purge gas is periodically terminated for a predetermined interval of time during which air begins to migrate into the flare system. Before this admittance of air can result in a hazardous condition within the system, the purge gas flow is re-established to sweep the air back out of the system.
