Abstract: An item of clothing for personal air-conditioning which has at least one three-dimensional air-flow guiding structure. The air-flow guiding structure is an air-impermeable woven spacing fabric. At least one pocket exists to accommodate an air-pumping device. The pocket interior is connected to the structure which allows for an air-flow capable of being supplied by the air-pumping device into the structure or out of the structure and connected to the environment allowing air to be drawn from or expelled into the environment.

Abstract: Waste gases are purged by adding to the gas while it flows through an abser a neutralizing agent together with water and then subjecting the gas to cooling so as to evaporate the added liquid. The adsorption then results in a reaction with the neutralizing agent whereby dry salts are formed which are removed from the process. The temperature of the waste gas is automatically and continuously measured and the volume of the water is adjusted automatically and continuously in accordance with the temperature measurements. The amount of waste gases is furthermore automatically and continuously measured, preferably at several places of the process, and the amount of neutralizing agent is continuously and automatically adjusted to the latter measurements so as to obtain always the stoichiometric equivalent for the reaction with the pollutants.
