A system and method recover process gas from a source volume at a source pressure to a destination volume at an equal or greater pressure. A regulation process receive the process gas from the source volume and steps down the pressure. Each regulation uses one or more stage each using a pressure control valve for pressure step down and a heat exchanger for reheating the process gas thereafter. A gas scrubber receives the process gas from the regulation stages and collecting liquid from the process gas. A compression process receives the process gas from the gas scrubber and steps up the intermediate pressure to a final pressure. The compression can use one or more compression stages, each having a compression cycle for pressure step up and a heat exchanger for cooling the process gas thereafter. A discharge vessel receives the process gas from the compression process and discharges the process gas at the final pressure to the destination volume. The final pressure is equal to or greater than the destination pressure.

An atomization generator and a special high-pressure atomization generation device for increasing oil and gas field recovery are provided. The special high-pressure atomization generation device for increasing oil and gas field recovery includes an agent pot assembly, a gear pump, a metering pump, an atomization generator and pipelines. The gear pump is connected with the agent pot assembly through an agent pot liquid inlet pipe. The metering pump is arranged between the agent pot assembly and the atomization generator which are connected through the low-pressure manifold pipeline and the high-pressure liquid inlet pipeline. The high-pressure liquid inlet pipeline is connected with the liquid inlet pipe. The liquid inlet pipes are connected with the metering pump. The gas inlet pipe is connected with the high-pressure gas source through the high-pressure gas inlet pipe. The gas inlet cap is provided with a gas inlet pipe.

A volatile composition dispenser and a method of dispensing a volatile composition is provided. The volatile composition dispenser includes a reservoir for containing a volatile composition and a transport member having a first end portion and an opposing second end portion, and an evaporative surface. The first end portion of the transport member is in fluid communication with the reservoir and the second end portion of the transport member is in fluid communication with the evaporative surface. The volatile composition dispenser also includes an air pump in gaseous communication with the reservoir.

A water vapor filtration and delivery system having a water inlet coupled to a source of water, a pump for pumping an amount of water from the water inlet, a filtration unit connected to the water inlet that removes all contaminants larger than 50 nanometers, and a nozzle having an outlet orifice for distributing the filtered water vapor into a stream of air. The water vapor filtration and delivery system includes a locator module coupled to a plenum or a wall of an air duct and having a base plate attached to the plenum, a locator plate removably attached to the base plate, and at least one hand bolt. There is a flexible hose between the filtration unit and the locator module configured to transfer water from the filtration unit to the locator module and a rigid pipe between the locator plate and the nozzle.

Disclosed are an apparatus and a method for forming a gas-liquid mixture having a stable vapor concentration. The apparatus comprises a mixing unit (1), a guide unit (2) and an evaporation chamber (3). In the mixing unit (1), a liquid stream is directly injected into a gas stream to form a mixture. The mixture is guided into the evaporation chamber (3) through the guide unit (2). The liquid is able to be spread over the rough inner surface of the evaporation chamber (3) so as to form a gas-liquid mixture having a stable vapor concentration. The technique can be applied to adsorption measurements using ellipsometry, as well as other research and products requiring use of stable and very-low-speed fluids.

A volatile material dispenser includes a housing that defines a longitudinal axis and is configured to receive a refill containing a volatile material and a wick. The volatile material dispenser also includes a cylinder that includes an inner wall that defines an opening and an interior edge, a resistor embedded in the cylinder, and a heater chassis that includes an inner wall that defines a passage between an upper end and a lower end. The upper end of the heater chassis abuts the interior edge of the cylinder. In addition, the inner wall of the cylinder extends away from the longitudinal axis at a first angle and the inner wall of the heater chassis extends away from the longitudinal axis at a second angle.

Provided is an aerosol generating device which is capable of stopping aerosol generation at an appropriate timing. This aerosol generating device includes a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a circuitry which controls the power supplied from the power source on the basis of the measurement value. The circuitry controls to increase a power supply amount per unit time in response to a first condition that the measured value is equal to or larger than a first threshold being satisfied, and to decrease the power supply amount per unit time in response to a second condition that the measured value is less than a second threshold greater than the first threshold and a third condition which is different from the first condition and the second condition being satisfied.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.

A removable cartridge for use with a liquid diffusion device is provided. The removable cartridge includes a cartridge housing defining an internal housing cavity, partially filled with a liquid to be diffused, and a diffusion head positioned within the internal housing cavity with a venturi device for generating diffused liquid from the liquid contained in the internal housing cavity. The diffusion head defines at least a portion of a gas supply conduit that extends from a bottom end of the removable cartridge to the venturi device through the liquid to be diffused to enable the venturi device to be supplied with pressurized gas from an external source via the bottom end of the removable cartridge.
