ABSTRACT:
A spinning impingement multiphase contacting device and method for heat or mass transfer are disclosed. A first fluid, from which the transfer is to occur, is caused to impinge and be entrained in a spinning permeable element, creating a highly dispersed phase. The highly dispersed phase contacts the second fluid to cause the desired heat or mass transfer.
