Detection and control of aromatic compounds in combustion effluent
New Patents The process essentially consists of reintroducing into the cylinder, during the phase of intake of the fresh gas, a more or less large part of the waste gas. It is achieved by providing each cylinder (1) with a branch pipe (7) communicating with the cylinder through an auxiliary inlet valve (8) whose opening period corresponds to the intake top dead center, and with the inlet pipe (6). A shutter or a plug (9) allows to control the flow of waste gas recycled at the intake according to the working conditions of the engine. A decrease in the harmful substances and an improvement in the engine efficiency can be obtained at the same time thereby.

vertically separated shredders that are located in an enclosed shell that has an inert gas fed into it in a controlled manner by a purge system. A lift in an enclosed shaft raises the drums, two at a time, and deposits them into an airlock from which they are released one at a time into the upper shredder. A control system automatically processes the material through the apparatus from when the containers are placed into the lift until the material reaches the dispenser and insures that no stage of the process will commence until the proceeding and following stages are completed. The control system also provides safety checks at each stage to prevent handling or processing accidents.

A system to control contamination during the retrieval of hazardous waste comprising an outer containment building, an inner containment building, within the outer containment building, an electrostatic radioactive particle recovery unit connected to and in communication with the inner and outer containment buildings, and a contaminate suppression system including a moisture control subsystem, and a rapid monitoring system having the ability to monitor conditions in the inner and outer containment buildings.
Detecting the presence of PAC's in the effluent of a combustions system by detecting the presence of a high molecular weight PAC's having five or more rings. A position along the effluent stream is selected at which high molecular weight PAC's may be present. The effluent is illuminated with radiation having a wavelength absorbed by the high molecular weight PAC's in the gas phase. The fluorescence from the illuminated effluent is detected, and analyzed by comparison to the known fluorescence of high molecular weight PAC's in the gas phase to determine the presence of the PAC's in the effluent. The effluent composition may be controlled in response to the detection.
