  • Patent number: 9403122
    Abstract: An off gas purification system provides superior results to other systems for removing volatile organic compounds from off gas, especially off gas from soil, groundwater, industrial processes, pipelines and storage tanks. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that must be further treated to produce pollutant-free exhaust. A separation device cleans the influent gas/air by separating residual chemical vapor from the gas stream and returning that chemical vapor to the compression and condensation step. After removal of all detectable volatile organic compounds, the air stream may be further separated into segregated gases, and heated gas is used to thermally enhance the desorption or degradation of volatile organic compounds from the off gas source or a separation device.

  • Patent number: 8992670
    Abstract: A method for removing one or more volatile organic compounds (VOCs) from a gas stream, in which the method includes adsorbing one or more of the gaseous volatile organic compounds (VOCs) on a granular activated carbon (GAC) obtained from date palm pits. The granular activated carbon is obtained by a process of: cutting the date palm pits into particles; mixing the particles with an acid solution to form soaked date palm pits; transferring the soaked date palm pit particles to stainless steel tubes; heating the tubes inside a muffle furnace; transferring the tubes to a desiccator and cooling; washing the granular activated carbon samples with water and drying; and sieving the samples. The obtained GAC is successfully tested under dynamic continuous gas flow conditions for gas phase benzene removal under a varying set of conditions including different gas phase benzene concentrations.

  • Patent number: 8986429
    Abstract: An off gas extraction system provides superior results to other systems for cleaning polluted soil. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas further treated to produce pollutant-free exhaust. A regenerative adsorber cleans the influent gas/air by adsorbing residual chemical vapor and concentrates the removed chemical vapor and reprocesses them. Conventional scrubbers are used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are likewise taught including combinations and additions consistent with schemes as they evolve.
