Abstract: Apparatus and an associated method of operation are disclosed for removal of gaseous contaminants, particularly oxygen, from closed containers. The apparatus is economical, simple to install and operate, of convenient size, and highly effective. A gas extractor communicates with a container for a gas-sensitive product. A high gas concentration in the container causes operation of the extractor until the gas concentration is reduced to a desired low level, when the extractor operation stops. Separate sensors and controllers responsive to concentrations can be present, or the extractor can be self-actuated by use as a power source of a battery which operates on gas generated by operation of the extractor. The system preferably is used for oxygen extraction from containers holding oxygen-sensitive contents. The preferred extractor includes an electrochemical cell which has a ion-permeable membrane disposed between two electrodes.

Abstract: A chemical-liquid controlling apparatus is described. The chemical-liquid controlling apparatus is mounted between a chemical-liquid container and an exhaust apparatus. During a chemical-liquid refilling process, once the chemical liquid is drawn out of the container by the exhaust apparatus, the chemical liquid first enters the chemical-liquid controlling apparatus. The chemical-liquid controlling apparatus separates the chemical liquid from a nitrogen gas and a chemical gas. In addition, the chemical-liquid refilling process is stopped by a signal transmitted from a leak sensor.

Abstract: Apparatus for removing gases from a container used to prepare concentrates of a powder in water are disclosed including a supply conduit for supplying water to the container, a removal conduit for removing the concentrate from the container, a pump including a negative pressure side, an evacuation conduit for connecting the negative pressure side of the pump with the container, an actuatable valve disposed in the evacuation conduit whereby upon actuation the actuatable valve connects the container with the negative pressure side of the pump, an indicator for indicating when the container includes a predetermined amount of the gases, and a control mechanism for actuating the valve in response to the indicator to eliminate the gases from the container.

Abstract: A system for separation of fluids and drill cuttings received from a borehole during an under-balanced drilling procedure. The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zone, and to provide effective separation and to reduce the detrimental effect due to the presence of the drill cuttings in the returned drill fluids. In the present invention there is utilized a first stage, high pressure vessel in which a major portion of the gases ad drill cuttings are separated, and a second stage, horizontal low pressure vessel, preferably of greater volume than the high pressure vessel, in which further separating is achieved, including the separate removal of the drilling liquid to be returned to the drill tube.

Abstract: An apparatus for cleaning hydraulic fluid includes a centrifugal fluid-spinning disk arranged in a housing, of which an upper portion forms a vapor chamber and a lower portion forms a fluid collecting basin. A vacuum pump is connected to the housing through an oil mist separator, such that water vapor is vacuumed away and hydraulic fluid collects in the oil mist separator to then be pumped away. The apparatus further includes preferably a single container that contains both the contaminated hydraulic fluid that is to be cleaned and the cleaned hydraulic fluid. A flexible inlet line and a flexible outlet line with respective hydraulic quick connectors are provided to connect the apparatus and particularly the oil container to a hydraulic system of an aircraft, for example. A high pressure pump connected to the outlet line pumps the cleaned hydraulic fluid into the aircraft hydraulic system and a pressure maintaining valve in the inlet line maintains the system pressure.

Abstract: Apparatus for removing volatile contaminant compounds from a liquid by sparging a cleaning gas therethrough comprises a volatile contaminant extraction assembly including a hollow porous tube surrounded by an outer jacket defining a gas plenum between the jacket and the porous tube; a contaminated liquid feed assembly including a nozzle for injecting liquid into the porous tube in a spiraling flow pattern around and along the porous tube; a gas-liquid separator assembly including a nonporous degassing tube coaxially aligned with and connected to the porous tube, a separator tube coaxially aligned with and connected to the degassing tube and flaring outwardly in diameter from the degassing tube, and a gas duct coaxially aligned with the separator tube and extending into the separator tube to collect and convey cleaning gas therefrom; a clean liquid collection assembly; and a gas discharge assembly.

Abstract: A steam condensate recovery component particularly useful for pressurized deaerator units, the recovery component being a vertical extension pipe of thermally conductive material connected to a system air vent and extending into the atmosphere. The extension pipe includes a thermally controlled steam trap at the distal end of the extension pipe for blocking escape of steam and allowing return of recovered condensate to the deaerator unit.

Abstract: A foam control system is provided for eliminating foam in a process fluid system, such as foam generated in the course of blanching steps and the like involving processing of potatoes or other food products. The foam control system includes one or more capacitive type proximity probes for detecting the presence of foam in a corresponding number of process fluid systems or tanks, and for automatically supplying a spray of a selected defoamer agent to the tank. The defoamer agent spray is supplied to the tank for a selected time interval, with a portion of the spray being directed at the associated detector probe to insure clearing of foam from the probe.

Abstract: A flow passage into which water-to-be-treated flows is provided with, in order from an upstream side, a deaerator as a DO eliminating device having a power variable mechanism, an oxidation device for oxidizing TOC by irradiating ultraviolet-ray, an ion eliminating device for eliminating TOC ion generated at oxidation, and a particle eliminating device. Further provided thereat are a TOC density measuring device, a DO density measuring device and a data processing device. Before the water-to-be-treated is irradiated with ultraviolet-ray in the TOC eliminating device (oxidation device and ion eliminating device), the deaerator controls a DO density in the water-to-be-treated according to a TOC density. Thus, an oxidizer of the TOC is maintained and impurity is decreased.
