  • Patent number: 8425664
    Abstract: Petroleous production is associated with effluents well known to foul lines, nozzles, and containers while consuming substantial energy to assist in both production and remediation. A heat exchanger and manifold system maximizes flows, minimizes changes in flow cross-section, and maximizes heat transfer area, while recycling both water and heat between processes. Dirty regions and clean regions result from scrubbing horizontal exhaust stacks and evaporation of production water in concert to remediate one another, while recycling a significant portion of the energy consumed by each. The heat exchanger relies on a manifold having many layered conduits, each connected to a single layer level of one or more cylindrical conduits in the exchanger. The cylinders of the exchanger themselves are arranged in multiple layers, each layer of a heat exchanger element being connected to a single layer of the manifold.

    Abstract: In a process, a portion of a liquid mixture flow is vaporized to produce a vapor and a depleted flow of liquid. The vapor is introduced to a brine which is adapted to exothermically absorb one or more components therefrom, and heat is withdrawn, to produce at least a flow of heat and a flow of brine which is enriched in the one or more components. The heat previously withdrawn is transferred, to drive the vaporization. This transfer can be associated with the change of a working fluid from a gaseous into a liquid state. In this case, the heat withdrawal involves the change of the working fluid from the liquid to the gaseous state. In the liquid state, the working fluid flows only by one or more of gravity, convection and wicking. In the gaseous state, the working fluid flows only by one or more of diffusion and convection.

  • Patent number: 7785399
    Abstract: Systems and processes utilize one or more methods of providing overhead waste process heat to increase the feed temperature of the hot solvent stripping regeneration loop in an acid gas removal process. A heated rich solvent stream can be the primary feed for the hot solvent stripping regeneration loop, and one or more slip streams can be heated and then combined with the heated rich solvent stream to form a combined rich solvent stream prior to further processing in downstream units to remove acid gas from the solvent. A first slip stream can be heated in a stripper gas heat exchanger by heat exchange with a stripped gas stream. A second slip stream can be heated in a regenerator exchanger by heat exchange with an acid gas stream. A third slip stream can be heated in a recycle gas exchanger by heat exchange with a compressed recycle gas stream.

  • Publication number: 20100122899
    Abstract: The present invention generally relates to the small-scale separation of a mixture of two or more components with different boiling points into enriched fractions. In some embodiments, a first and second fluid (e.g., a liquid and a gas, a liquid and a liquid, etc.) are passed through a channel. The first fluid may comprise at least two components, each with a unique boiling point. Upon contacting the first and second fluids within the channel, at least a portion of the most volatile of the components in the first fluid (i.e., the component with the lowest boiling point) may be transferred from the first fluid to the second fluid. In some instances, the transfer of the volatile component(s) from the first fluid to the second fluid may be expedited by heating, in some cases above the boiling point(s) of the component(s) to be transferred from the first fluid to the second fluid. Contact between the first and second fluids may be maintained, for example, via segmented flow, bubbling flow, etc.

  • Patent number: 7699914
    Abstract: A method of using a triple-effect absorption system to recover methane from landfill gas contaminated with CO2 and trace contaminates such as chlorinated hydrocarbons and aromatics involves processing the landfill gas with three absorbers and a flash system. One absorber uses a solvent to absorb the trace contaminants from the landfill gas, the second absorber in conjunction with the flash system extracts CO2 from the gas, and just a first portion of that CO2 is used for stripping the trace contaminates from the solvent in the third absorber. The rest of the extracted CO2 is vented to atmosphere to prevent dampening the combustion of the trace contaminants absorbed by the first portion of CO2.
