摘要
A method for operating a multi-track rotary valve having plural tracks for the separate introduction to vessels of at least 3 feed streams and the separate recovery from the vessels of at least 3 product streams and for simultaneous change of the flow paths of the streams. At least one stream is selected and maintained at lower pressure than the other streams so that any leakage flows from the other streams to the at least one selected stream.
