HYDROSTATIC CONTROL OF A PRESSURE DIFFERENTIAL BETWEEN GAS AND LIQUID STREAMS

摘要

A control method simply and reliably regulates the relative pressure across boundary surfaces that comprise opposite faces of a single element or are the outer surfaces of compound structure and at least partially separates the flow of a gas and a liquid thereacross by sending at least some of the gas that contacted boundary surface to a column of liquid (38) and adjusting the height of the liquid therein to provide a consistent back pressure on the gas flow from its boundary surface. The control method also permits regulation of back pressure on the liquid by maintaining a column of the liquid that flows from its boundary surface at a relatively constant elevation and controlling the flow of liquid out of such retained column of the liquid flow stream.
