ABSTRACT:
A head flush apparatus for a pressure vessel uses an equalization chamber that channels the fluid generated by the head flush into a low volume chamber and withdraws fluid from the pressure vessel through the low volume chamber. Withdrawing fluid generated by the head flush and channeling the fluid through the low volume chamber reduces or eliminates the circulation of fluid between the equalization chamber and the adjacent process chamber and minimizes the amount of contamination that can result from any circulation of fluid resulting from pressure fluctuations. The withdrawal of fluid through the low volume chamber also provides a non-contaminating path for withdrawing leakage from the vessel.
