  • Patent number: 8709135
    Abstract: An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

The palladium doped ZSM-5 has a Si:Al ratio of less than or equal to 100:1 and preferably has a palladium content of from 0.1 wt % to 10.0 wt % based on the total weight of the doped ZSM-5.

  • Patent number: 8435329
    Abstract: Gas fired internal combustion engines which are run on contaminated fuel suffer from the buildup of internal deposits and corrosion. This is a particular problem with engines fuelled by biogas, e.g. from waste decomposition. By filtering the fuel via a filter containing an ion-exchange resin substantial improvements can be obtained.

  • Patent number: 8414691
    Abstract: The system and method for recycling and using the heat from compressed gas produced by a biogas treatment plant. The system includes a biogas cleaning stage and a plurality of compression and heat exchanger stages that allows the heat generated by compressed gases to be harvested. After the heat is harvested, it is delivered to a jacketed vessel containing media used to remove contaminants from the biogas. The media inside the jacketed vessel requires regeneration or stripping of harmful VOCs and other contaminants picked up from the biogas. The system also includes an inert gas generator that creates hot inert gas that is delivered to the jacketed vessel that heats the media located therein to remove contaminants. Because the jacket vessel and the media are simultaneously heated, the system's heat-up time is reduced The system also includes a heat exchanger that partially recovers the heat from the inert gas.

  • Patent number: 8398747
    Abstract: This invention relates in part to a process for producing high purity acetylene by withdrawing a crude acetylene stream from a storage source, and passing said stream through an adsorbent bed that contains layered adsorption media to selectively remove moisture, solvent and carbon dioxide from the stream, thereby producing the high purity acetylene. The adsorption media is regenerated in-situ. The high purity acetylene product is useful as a source material for depositing carbon and carbon-containing films in semiconductor applications.
