  • Patent number: 7172686
    Abstract: Methods of separating components of a mixture, such as crude oil, are disclosed which increase the yield of individual components while decreasing the yield of residue. In one method, a heated mixture is fed to a column, a vapor stream is withdrawn from the column and separated, and a portion of the vapor stream is recycled back to the column. In another method, a mixture is separated into streams composed substantially of components having light, intermediate or heavy molecular weight and/or low, intermediate or high boiling point, respectively, and the streams are fed into the column at different positions. In both methods, individual light, intermediate and/or heavy molecular weight and/or low, intermediate and/or high boiling point component streams are then selectively withdrawn from the column.

  • Patent number: 7153334
    Abstract: Carbonaceous material is removed from a catalyst within an autothermal reformer by introducing an isolated oxidant stream into the autothermal reformer prior to introduction of hydrocarbon fuel into the reformer. A hydrocarbon stream is introduced into the autothermal reformer following removal of the carbonaceous material. A concurrent supply of the hydrocarbon stream and the oxidant stream to the autothermal reformer is maintained such that an exothermic reaction driven by the oxidant stream provides heat to an endothermic reaction driven by water vapor in the hydrocarbon stream. In accordance with 37 CFR 1.72(b), the purpose of this abstract is to enable the United States Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract will not be used for interpreting the scope of the claims.

  • Patent number: 7108767
    Abstract: Useful byproducts are recovered through the pyrolytic processing of biomass material such as vegetation, paper, or worn tires. The process is conducted in a sealed enclosure under vacuum or other controlled atmosphere. The biomass material is ablated and burned by crunching between counter-rotating rollers whose inner walls have been exposed to a highly heated fluid. The biomass material is preheated by injecting into the feeding duct super-heated: dry steam. A condenser within the enclosure reduces resulting vapors into oils that can be drained from the enclosure pan. Solid combustion residue is abstracted from the enclosure by an Archimedes screw.

  • Patent number: 7101463
    Abstract: A system and process for the recovery of oil from the pyrolysis of material containing hydrocarbons such as shredded vehicle tires. The system utilizes a pair of sequentially positioned packed towers to recover at least 95% of the oil contained in the pyrolysis gases. The first packed tower operates above the dew point of the water vapor in the pyrolysis gases to insure that no water is condensed and obtain a primary oil fraction having oil with a high flash point of about 60° C. or greater and a primary vapor fraction containing additional oils, fuel gases and water vapor. The primary vapor fraction is fed to the second packed tower which operates below the dew point of the water vapor to condense the water and oil having a low flash point of 34° C. or below, and provide a secondary vapor fraction containing valuable fuel gases.

  • Patent number: 7094264
    Abstract: The present invention relates to a method for obtaining combustion gases of high calorific value, wherein carbonaceous materials are allothermically gasified in a fluidized layer containing solid particles, using a gaseous gasifying agent and by supply of heat, and the gases thus produced are separated from the solid particles and withdrawn. Said method is characterized in that the solid particles are indirectly heated in a first descending bed and supplied to a second ascending fluidized bed in which the fluidized layer is formed and gasification takes place for the greatest part.

  • Patent number: 7087140
    Abstract: A carbonizing waste processing apparatus is operable to rotate and heat a radiant tube for carbonizing waste therein so as to generate granular char and vapors from the waste, transfer waste into an upstream end of the tube, temporarily impede movement of the waste through the tube at upstream and downstream locations therein so as to ensure that residence time of the waste in the tube is sufficient at the upstream location to carry out evaporation of moisture from the waste and at the downstream location to elevate the temperature of any solids in the waste for completion of carbonization of the waste, discharge the granular char and vapors from the tube, and flow the generated and discharged vapors through a succession of finned heat exchanger tubes so as to condense and separate the vapors into oil, water and methanol.

  • Patent number: 6974785
    Abstract: The outer shell fabric according to the invention is made of a textile material which is a double-weave woven fabric or a warp-knit knitted fabric constructed in such a manner that preferably a majority of one yarn type is placed on the face of the fabric and the majority of a different yarn type is placed on the back surface. One of the yarns may consist of multi-filamentary meta-aramid fiber (e.g. Nomex), the other of either a multi-filamentary or a spun (staple) para-aramid fiber (e.g. Kevlar). The textile material can be visualized as two separate fabrics being interlaced together by the sharing of yarns between them. When used as part of a firefighter or work garment for protection against heat and flame, the outer shell fabric has superior tear resistance, abrasion resistance, UV resistance, and thermal protective performance when compared to other outer shell fabrics used for the same application.

  • Patent number: 6958019
    Abstract: A golf putter in which most of the clubhead mass is distributed at three or more prescribed locations within a “Mass Ring” approximately equidistant from, and as remote as possible from, the clubhead planar center of mass with the clubshaft axis preferably forward of the clubhead center of mass thus maximizing both putter and clubhead planar moment of inertia for improved putter performance during mis-hits. Maximum remote mass is achieved by interconnecting the remote high mass areas (Mass Ring) with the putterface striking area and the putter shaft connection point with a light weight rigid open (see thru) truss system so arranged to enhance the Sighting Field and/or sight or aim line on the putterhead while preventing undesirable vibration of individual clubhead members. Such Sighting Field and Sight Line can be further enhanced via use of one of several light weight replaceable and angular adjustable Sighting Fields and/or Sight Lines preferable to an individual golfer.

  • Patent number: 5958218
    Abstract: Hydrocarbon feedstocks are hydroprocessed in parallel reactors, while hydrogen flows in series between the reactors. A first hydrocarbon feedstock and a hydrogen-rich recycle gas stream are introduced to a first reactor, where a first reactor effluent stream is produced and fed to a first separator, which separates the first reactor effluent stream into a first hydrogen-rich gas stream and a first hydroprocessed product stream. The first hydrogen-rich gas stream and a second hydrocarbon feedstock are fed to a second reactor, where a second reactor effluent stream is produced and fed to a second separator, which separates the second reactor effluent stream into a second hydrogen-rich gas stream and a second hydroprocessed product stream. A make-up hydrogen stream is added to the second hydrogen-rich gas to form the hydrogen-rich recycle gas stream that is compressed and fed to the first reactor.
