Abstract: An automotive paint spray and drying booth having a plurality of walls which, together, define a housing with a chamber sufficient in size to contain an automotive vehicle. An air dispenser is positioned within the chamber and the air dispenser includes an outlet positioned to direct air along one or more of the housing walls. A regenerative blower is positioned outside the housing chamber. The blower is connected to an inlet open outside of the housing chamber and includes an outlet which is fluidly connected to the air nozzle.

Abstract: A paint drying booth includes a stationary structure of sidewalls, and a pair of opposed end walls including an access door for egress and ingress. A turbo-compressor is disposed exteriorly of the booth and delivers through a duct heated turbine air thereinto. The duct is in fluid communication with a nozzle which, in turn, is in fluid communication with an air knife having a slit which delivers turbulent air into the interior of the booth. A pair of diametrically opposed panels are disposed at the junction of the corners of the booth upon which air from the air knife impinges thereon to create a vortex within the booth. Optimally, a five bladed turbo-compressor is used. A seven bladed turbo-compressor may be used and which also delivers heated air to a spray gun disposed within the booth by a diverter.

Abstract: Natural gas liquefaction system employing an open methane cycle wherein the liquefied natural gas is flashed immediately upstream of the liquefied natural gas storage tank and boil off vapors from the tank are returned to the open methane cycle.

Abstract: Natural gas liquefaction system employing an enhanced nitrogen removal system capable of removing nitrogen from a relatively warm natural gas stream.

Abstract: Natural gas liquefaction system having an optimum configuration of mechanical drivers and compressors. A heat recovery system can be employed with the liquefaction system to enhance thermal efficiency. A unique start-up system can also be employed.

Abstract: Natural gas liquefaction system employing an open methane cycle wherein the liquefied natural gas is flashed immediately upstream of the liquefied natural gas storage tank and boil off vapors from the tank are returned to the open methane cycle.

Abstract: Natural gas liquefaction system employing electric motors as compressor drivers. A combination of motors and steam turbines can be powered by a cogeneration plant and employed as drivers.

Abstract: Natural gas liquefaction system employing a zeolite adsorbent for removing nitrogen from pretreated natural gas.

Abstract: A process for purifying a raw natural gas stream is provided by contacting the gas stream with an absorbant to remove water and hydrocarbon impurities, separating the water and hydrocarbon impurities and absorbant from the gas stream, separating the absorbant from the water and hydrocarbon impurities to provide a liquid absorbant stream and a water vapor and hydrocarbon vapor stream, condensing the water vapor and a portion of the hydrocarbon vapor stream to provide a mixed liquid/vapor stream, passing the mixed stream through a pump capable of pumping a mixed stream, and disposing of the thus-reduced volume, higher pressure, mixed stream. One aspect of the invention provides for the reintroduction of the mixed stream to the process with the raw natural gas, thereby eliminating volatile organic compound disposal concerns.
