A compact heat pump system and a heat pump operation method, which can avoid the occurrence of surging in a compressor at startup of a heat pump and can directly supply vapor of a working medium produced by the compressor to an external heat-utilizing facility. The heat pump system comprises an evaporator for recovering heat of an external heat source to a working medium supplied as liquid water from the exterior via a water feed channel, thereby evaporating the working medium, a compressor for compressing the working medium evaporated in the evaporator and increasing temperature of the evaporated working medium, and a driving unit for giving motive power to drive the compressor. The heat pump system further comprises a supply channel for supplying, as a heat source, vapor of the working medium having temperature increased by the compressor to an external heat-utilizing facility, and a return channel branched from the supply channel and introducing the working medium discharged from the compressor to the evaporator.

A buffer tank section (6) includes a liquid accumulation chamber (61) communicating with, through a liquid introduction flow path (42), a liquid tank (46) accumulation chemical liquid. A filter section (4) includes a filter inlet (41a) and a filter outlet (41b), wherein the filter inlet (41a) communicates with a liquid discharge vent (60d) of the buffer tank section (6). In a pump (11), a pump inlet (11a) is connected to the filter outlet (41b) and a pump outlet (11b) is connected to a discharge nozzle (50) through a liquid discharge flow path (47). A return flow path (48) is connected between the pump outlet (11b) and the buffer tank section (6), wherein the chemical liquid, discharged from the pump (11), is returned to the liquid accumulation chamber (61). An exhaust flow path (49) is connected to the buffer tank section (6), thereby exhausting air in the liquid accumulation chamber (61).

An aircraft fuel deoxygenation system includes a boost pump, a contactor-separator, and a centrifuge-separator pump. The boost pump is adapted to receive fuel from a fuel source and inert gas from an inert gas source, and is configured to mix the fuel and inert gas and supply a fuel / gas mixture. The contactor-separator is coupled to receive the fuel / gas mixture and is configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel with entrained purge gas and separated purge gas. The centrifuge-separator pump is coupled to receive the deoxygenated fuel with entrained purge gas and is configured to separate and remove the entrained purge gas from the deoxygenated fuel and supply the deoxygenated fuel and additional purge gas.

An arrangement and method for the degassing small high-aspect ratio drilled holes or vias which are present in panels such as printed circuit boards prior to wet chemical processing, including copper plating of the vias, in order to remove any air or gas bubbles from the vias tending to inhibit the reliable plating thereof. This is carried out through the utilization of an ultrasonic prewetting in a liquid bath preceding cleaning for the electroless plating process, thereby enabling all of the vias or holes to be degassed; in effect, having air removed and the vias or holes filled with liquid; thereby allowing subsequent process cleansing solutions to easily flow into the respective holes or vias in order to facilitate the electroless copper plating process.

A process for removing oxygen from a copper plating solution is provided. The solution is passed through a degasser comprising a shell and hollow hydrophobic fiber porous membranes wherein the shell while a vacuum is drawn on the surfaces of the fibers opposite the fiber surfaces contacted by the solution. Gas passed through the fiber walls while liquid is prevented from infiltrating the fiber pores. The composition of the solution is monitored so that the composition can be retained substantially constant by adding components of the solution as needed.

The amount of chemical liquids dispensed by a chemical liquid supply apparatus is stabilized and dispensing accuracy is remarkably improved. A pump discharges a liquid accommodated in a liquid tank. A filter is connected to the pump through a pump outlet flow path to which a pump discharge-side valve for opening / closing the flow path is provided. A dispensing nozzle (liquid dispense portion) is connected to the filter through a liquid discharge flow path to which a discharge valve for opening / closing the flow path is provided. A vacuum source communicates with the filter through an exhaust flow path to which a deaeration valve for opening / closing the flow path is provided.

A fuel system for an energy conversion device includes a multiple of fuel plates, oxygen permeable membranes, porous substrate plates, and vacuum frame plates which define a wave pattern configuration. The wave configuration enhances deoxygenation by increasing the efficiency and integrality due to higher surface volume ration, increase of flow turbulence, and minimal sharp edges which may otherwise damage the oxygen permeable membranes compared to other configurations.

Integrated gas oil separation plant systems and methods are disclosed. Systems and methods include treating a crude oil inlet feed stream with a high pressure production trap (HPPT), a low pressure production trap (LPPT), a low pressure degassing tank (LPDT), a first heat exchanger, a second heat exchanger, a LPPT recycle water stream, a fresh wash water supply stream, and a LPDT recycle water stream, where the LPDT recycle water stream is operable to supply recycle water from the LPDT to an output stream from the HPPT to form the LPPT inlet feed stream.
