This disclosure relates to a system that provides an environmentally friendly method to clean air over towns and cities. The system utilizes tourmaline filters and rocks, sunlight, and water to simulate the cleaning properties of waterfalls in order to create an ionized surface within a cylindrical tube and creates raindrops and mist to simulate precipitation. The system eliminates pollutants instead of transferring them to the surrounding environment.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

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 vehicle, with or without using flow-establishing devices.

A method for operating a surface treatment installation wherein overspray that occurs in one or more coating booths is taken up by a booth air stream. Booth air laden with overspray is conducted to at least one separating unit in which overspray is separated out. The booth air laden with overspray or the booth air free of overspray is fed a solidifying material on its flow path to at least one separating unit and/or the booth air laden with overspray or the booth air free of overspray is fed a solidifying material in the interior of at least one separating unit and/or overspray that has already been deposited in at least one separating unit is fed a solidifying material and/or the at least one separating unit is fed a solidifying material before the separating unit is functionally fitted in the surface treatment installation, wherein the solidifying material has the effect that a curing process in the overspray is initiated or assisted. A device for separating out overspray from the booth air laden with overspray of surface treatment installations. Booth air laden with overspray can be passed through at least one separating unit, in which overspray is deposited. There is a solidifying material feeding device, by means of which the booth air laden with overspray can be fed a solidifying material on its flow path to at least one separating unit and/or the booth air laden with overspray can be fed a solidifying material in the interior of at least one separating unit and/or overspray that has already been deposited in at least one separating unit can be fed a solidifying material, wherein the solidifying material has the effect that a curing process in the overspray is initiated or assisted.
