Abstract: A water removal composition and methods for using the same to remove excess water from a surface. The composition comprises a silicone polymer, quaternary ammonium emulsifier, co-emulsifier and an HLB stabilizing agent that modifies a treated surface to form a continuous hydrophobic layer enhancing water removal from the surface. The novel water removal compositions and methods for using the same result in a significant reduction of energy expenditure to remove excess water through air blowers and/or mechanical removal.

Abstract: A process for controlling the volume of dry air, dried to a predetermined degree of dryness, from a sweep manifold of an air dryer system, flowing over a plurality of gas/liquid fluid separating membranes, comprising: diverting a predetermined volume of dried air to the manifold; sensing one of the flow volume and humidity values of the remainder of the dried air or the pressure differential within the system; and utilizing one of the differential pressure to control the predetermined volume of dried air and utilizing a controller for achieving the predetermined degree of dryness by controlling at least one solenoid valve which, in turn, controls the flow volume of the predetermined volume of dried air diverted to the manifold.

Abstract: An integral coalescer filter-membrane device to provide clean sample gas to gas analyzers. The device includes a housing, an inlet port for feed gas, an outlet port to withdraw clean sample gas essentially free of entrained liquids, such as water, and particulate material which might contaminate or interfere with the gas analyzer, a bypass port and a drain port to remove by gravity coalesced liquid. The device includes a filter tube to coalesce and filter the feed gas stream and a chamber having a supported hydrophobic selected porosity membrane. The outlet port receives clean sample gas from the upper portions of the chamber, while the bypass port removes coalesced filtered gas from a lower chamber.
