Abstract:
A method for cleaning an interior surface of a processing equipment using a treatment liquid, the processing equipment including a pipe section defining pipe section first and second ends, the pipe section defining a pipe section volume delimited by the pipe section first and second ends, the pipe section being initially at an initial internal pressure. The method includes introducing a predetermined volume of the treatment liquid, the predetermined volume being substantially smaller than the pipe section volume circulating the predetermined volume of the treatment liquid through the pipe section by simultaneously reducing an internal pressure within the pipe section at a location substantially adjacent the pipe section second end and increasing an internal pressure within the pipe section at a location substantially adjacent the pipe section first end.
