  • Process for treating metal-contaminated materials
    Patent number: 5556447
    Abstract: A process for treating wastes contaminated by toxic metals and/or organic materials is disclosed. The process involves heating the metal-contaminated wastes to a temperature sufficient to volatilize the metals. This temperature is also high enough to destroy or volatilize organic contaminants. The metal vapors are contacted with a sorbent which is reactive with the metals and sequesters them, thereby forming a non-leachable complex which can be disposed as non-hazardous conventional waste.
    Type: Grant
    Filed: January 23, 1995
    Date of Patent: September 17, 1996
    Assignee: Physical Sciences, Inc.
    Inventors: Srivats Srinivasachar, Joseph Morency, Daniel C. Itse
  • Apparatus for combustion, pollution and chemical process control
    Patent number: 5275553
    Abstract: Disclosed is a system for regulating the efficiency of a combustion process by detecting radiant energy emitted from ash particles entrained in the gas stream exiting the combustion chamber of a boiler or incinerator. The intensity of selected wavelengths of light emitted from the particles is indicative of the temperature of the particles. The change in the intensities of the selected wavelengths of light, and thus of the temperature of the gas stream at the furnace exit, is monitored, and a feedback control mechanism is used to regulate one or more combustion, pollution control, or heat transfer parameters thereby maximizing the thermal efficiency of the combustion process in the boiler or incinerator.
