Abstract:
A hazardous gas abatement system decontaminates an exit gas stream containing global warming gases using an electrical heater and a water scrubber. One or more top flow hazardous gas inlets introduce hazardous gases into a heater compartment. Air or oxygen is introduced into a separate chamber for dynamic oxidation and cooling. The streams are mixed and oxygen reacts with the hazardous gases. Solid particulates from the reaction are removed by a filter in a quick disconnect bottom chamber. Filtered exhaust gases flow upward in an exhaust chamber surrounding the heater compartment and through water spray scrubbers. A cleaning ring mounted on an eccentric rod cleans particles from the outside of the internal heater, and the inside of the external heater. An air cylinder drives the eccentric rod and cleaning ring down and up between the heaters and stores the ring above the gas inlets.
Abstract:
System for removal of targeted pollutants, such as oxides of sulfur, oxides of nitrogen, mercury compounds and ash, from combustion and other industrial process gases and processes utilizing the system. Metal oxides, such as oxides of manganese, are utilized as the primary sorbent in the system for removal or capture of pollutants. The metal oxides are introduced from feeders into reaction zones of the system where they are contacted with a gas from which pollutants are to be removed. With respect to pollutant removal, the sorbent may interact with a pollutant as a catalyst, reactant, adsorbent or absorbent. Removal may occur in single-stage, dual-stage, or multi-stage systems with a variety of different configurations and reaction zones, e.g., bag house, cyclones, fluidized beds, and the like. Process parameters, particularly system differential pressure, are controlled by electronic controls to maintain minimal system differential pressure, and to monitor and adjust pollutant removal efficiencies. Reacted sorbent may be removed from the reaction action zones for recycling or recycled or regenerated with useful and marketable by-products being recovered during regeneration.
Abstract:
Incineration systems, particularly those using municipal garbage and waste, refuse-derived fuels, coal and petroleum coke, and/or chlorinated hydrocarbons are operated without the release of toxic pollutants such as dioxins. One preferred embodiment relates to a non-polluting method for burning fuel derived from typical municipal garbage and waste eliminating, or at least significantly reducing, the need for the landfill disposal of such waste materials. In an alternative application, air, water, coal and/or petroleum coke are used to produce electricity, urea, and methanol in a non-polluting manner.
Abstract:
According to a process for treating perfluorides in which a perfluoride treatment undertaker carries out decomposition treatment of perfluorides discharged from a manufacturing plant by using a perfluoride treating apparatus connected to said manufacturing plant, and the cost of treatment of perfluorides calculated according to the amount of perflorides treated by said perfluoride treating apparatus is communicated to the owner of said manufacturing plant, it is possible to reduce the cost required for the decomposition treatment of perfluorides which cost is to be defrayed by the product manufacturer.
Abstract:
A waste gas treatment system having a burner part and a combustion chamber provided at the downstream side of the burner part, wherein combustion flames are formed from the burner part toward the combustion chamber, and a waste gas is introduced into the combustion flames, thereby oxidatively decomposing the waste gas. The combustion chamber is formed from an inner wall made of a fiber-reinforced ceramic material. Therefore, the wear of the inner wall due to heat and corrosion is minimized, and thermal stress cracking is also reduced. Consequently, the lifetime of the system increases, and the cost of equipment and the availability factor can be improved. In addition, because the inner wall exhibits no catalytic effect, the formation of thermal NOx is suppressed, and it is possible to achieve environmental preservation and to simplify the treatment equipment.

Abstract:
A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.
