Vaporizing Patents (Class 196/104)
  • Publication number: 20120073932
    Abstract: Generally, the present disclosure is related to systems and methods for separating hydrocarbons and/or other liquids from drill cuttings material. One illustrative embodiment disclosed herein is directed to a system that includes, among other things, a thermal reactor that is adapted to remove liquid from drill cuttings material by heating the drill cuttings material to at least a first temperature that is sufficiently high enough to vaporize the liquid. The illustrative system also includes a feeder system that is adapted to controllably feed a flow of the drill cuttings material to the thermal reactor, and a control system that is adapted to control the flow of the drill cuttings material from the feeder system so as to maintain a temperature in the thermal reactor at or above the first temperature.

  • Patent number: 8025857
    Abstract: An apparatus is described for the preferential conversion to 2-butene of a stream containing C4 compounds including 1-butene and 2-butene involving mixing the C4 stream with a first hydrogen stream to form a feed stream, hydroisomerizing the feed stream in the presence of a first hydroisomerization catalyst in order to convert at least a portion of the 1-butene to 2-butene, thereby producing a hydroisomerization effluent, passing the hydroisomerization effluent through a fractionation column to form a top stream comprising isobutane and isobutylene and a bottoms stream comprising 2-butene, withdrawing a recycle stream from said fractionation column at a location above the feed point at which the weight ratio of 1-butene to 2-butene is high, and combining the recycle stream with at least one of the C4 stream and the feed stream upstream from the hydroisomerization catalyst.

  • Patent number: 7608218
    Abstract: A chemical vapor sterilization process is enhanced by flowing a portion of the sterilant vapor through an instrument container using a normal portion of the exhaust process. Preferably, an exhaust conduit which draws a vacuum on a sterilization chamber is oriented so that the container is adjacent an inlet to the conduit.

  • Patent number: 4994169
    Abstract: A process and apparatus for the recovery of oil from aqueous oil refinery waste involves mixing the waste with a fluidizing oil and evaporating the water from the mixture in a plurality of stages. The dewatered mixture is fed to a delayed coking system in which a conventional coker feedstock is being used. The heavy hydrocarbon portion of the dewatered mixture changes to coke and light hydrocarbon material, the inert solids become trapped in the coke, and the fluidizing oil vaporizes. A stream of heavy coker gas oil is fed from a fractionator in the delayed coking system to a fluidizing tank where it is mixed with the sludge to define the fluidizing oil. Another hot stream of hydrocarbon material from the coker fractionator is sent to the evaporator section to provide the heat for evaporation.

  • Patent number: 4994149
    Abstract: In a process for the treatment of heavy oil, in which a hydrocarbon diluent is added to the heavy oil stream, part of the diluent is substituted by an LPG liquid stream. The LPG stream is added to the heavy oil stream after removal of light components including methane and carbon dioxide to reduce the vapor pressure of the stream, producing a sales oil stream.

  • Patent number: 4351803
    Abstract: Hydrocarbons are preheated, particularly for a hydrodesulfurization process by first heating the hydrocarbon stream to produce a vapor and a liquid stream, thereafter superheating at least some of the vapor phase and mixing the superheated vapor phase with the liquid phase to generate the hydrocarbon feedstream at the desired temperature. By this procedure only the evaporated hydrocarbons are subjected to a high temperature, but not the heavier hydrocarbons.
