Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

An air scenting system for a vehicle is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance is particularly adapted for dispensing scent into the interior space of a vehicle, and includes a form factor particularly well suited for positioning the appliance in a cup holder. Additionally, the appliance is designed for use in vehicles when a driver is present and readily adjustable by the driver to provide a uniform scent experience.

An environmental sampling chamber for sampling the particulates and substances emitted from a test sample when the surface of the sample is ablated. The sampling chamber avoids the need for clean rooms and other expensive testing apparatus and can be used to test a variety of materials in accordance with standard measurement procedures. Use of the testing chamber and methods assists with safety and risk evaluation in applications such as painting and removal of coatings.

A liquid filter apparatus for gas/solid separation includes a housing with a filter chamber, a semiconductor process gas inlet, and a process gas outlet. The filter chamber forms a liquid reservoir, and the semiconductor process gas inlet and the process gas outlet are in communication with the filter chamber. The housing further includes a filter liquid inlet and a filter liquid outlet, which are in communication with the liquid reservoir for delivering and removing filter fluid, respectively, to and from the liquid reservoir.

An exhaust unit includes a dirty air intake opening, a clean air output opening and an airflow path defined between the dirty air intake opening and the clean air output opening. The exhaust unit further includes an upstream quenching section and a downstream filtering section along the airflow path. The quenching section has a wetting chamber that includes a reservoir having a fill level for a quenching liquid, and a downtube connected over the dirty air intake opening and opening at its end above, and in opposition to, the plane of the fill level.

A process gas suction structure for preventing a generation of products from a process gas due to a temperature drop is disclosed. The process gas suction structure includes a double tube structure, and a heating device configured to heat the double tube structure. The double tube structure includes a process-gas flow passage portion where the process gas flows, and a partition portion arranged outside of the process-gas flow passage portion.
