Described herein are various embodiments of an oxygen concentrator system. In some embodiments, oxygen concentrator system includes one or more components that improve the useful lifetime of gas separation adsorbents.

A mobile emissions control system having an emission capturing system and emission control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. A crane or boom transfers a duct of the emissions capturing system extending from the emissions control system to the ship to capture exhaust from its engine. Alternatively, the system may be mounted on an automated guided vehicle (AGV) equipped with a tower and a crane. The crane mounted on the AGV then lifts the duct forming part of the emissions capture system to the ship's exhaust system to capture exhaust from the ship's diesel engine and transfers it to the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.

Ionization systems and methods include moving air into contact with one or more ion generators and then past an ozone removal assembly to remove at least some ozone from the air. The air may be moved by a fan and may be filtered before contacting the one or more ion generators. The amount of one or more of the following of the air may be measured: the amount of ions, particulates, temperature, humidity, and other relevant factors. The ionization amount may be adjusted based on one or more of the measured amounts. The one or more ion generators and ozone removal assembly may be constructed as part of a single unit so they can be removed and replaced easily.

The invention relates to an improved method and to an improved device for degassing polymer melts and for neutralizing the thus produced pollutants, characterised by the following characteristics: said pollutants are guided to a plasma source after removal from the degassing area and prior to adding to a filter step or a separator, said plasma source being built and/or formed such that in said plasma source, the pollutants are transformed, entirely or partially, in a plasma aggregate state.

A device for the destruction of biohazardous converts harmful waste products into environmentally friendly discharge in compliance with environmental protection agency (EPA) standards. The device includes a waste disposal chamber where a crucible resides. The crucible contains a basket for holding the waste which is heated through induction coils that surround the crucible. The waste is vaporized and ionized in a vacuum forming a waste gas and drawn through a catalytic converter and a hot plasma jet via vacuum suction. The waste gas is then exhausted via a discharge duct where is it condensed by a heat exchanger further refining the waste gas into environmentally friendly molecules such as carbon dioxide. The waste destruction device further includes a programmable logic controller and user interface to control the device. Once the waste destruction process is completed, a compressor passes compressed air over the crucible to rapidly cool the crucible,

An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.

A semiconductor waste abatement system for a semiconductor processing system includes a vacuum pump, an abatement apparatus having an abatement chamber in fluid communication with a source of semiconductor waste gas from the semiconductor processing chamber, and with the abatement chamber configured to ionize the waste gas and to exhaust ionized gas. The abatement system further includes a filter apparatus with a filter chamber, which forms a liquid reservoir. The inlet of the filter apparatus is in fluid communication with the outlet of the abatement chamber and the liquid reservoir, and the outlet of the filter apparatus is in communication with the inlet of the vacuum pump, wherein the filter chamber is under a vacuum, and wherein semiconductor waste gas is ionized in the abatement chamber and then filtered by the filter apparatus prior to input to the vacuum pump.

The present invention removes, by a preprocessing unit, harmful chemical materials and radioactive materials supplied to a positive pressure chamber and a negative pressure chamber and supplies same, removes contaminants discharged to the outside from the negative pressure chamber and sterilizes bacteria and floating viruses and discharges same, and adjusts, by a control circuit of a control panel, the rotating speed (RPM) of an air supply/discharge fan and adjusts the opening rate of an electric damper according to data that is measured in a pressure sensor provided in a space in which the positive pressure and the negative pressure are to be maintained and is transmitted in real time.

A system for condensing vapor product is provided. The system includes a first duct configured to receive a vapor product having a first humidity level, the first duct having a first charge in response to application of a first voltage to the first duct so as to ionize the vapor product. A second duct is configured to allow the ionized vapor product to pass therethrough and configured with a second charge in response to application of a second volt age to thereby allow collection of at least a portion of liquid particles present in the ionized vapor product and form a first modified vapor product. A chamber is configured to receive the first modified vapor product and includes at least one cooling plate configured to reduce a temperature of the first modified vapor product, and at least one first mesh plate configured to collect at least a portion of liquid particles. Methods for condensing vapor are also provided.
