    Abstract: A method of removing suspended solids from a gasification process water stream includes, in an exemplary embodiment, providing a gasification process water stream containing process derived suspended solids, settling at least a portion of the suspended solids from the process water stream in a settling apparatus, providing a filter apparatus having a plurality of filter elements, and removing a portion of the settled solids from the settling apparatus. The method also includes precoating the filter elements with the settled solids removed from the settling apparatus, directing a portion of the process water stream from the settling apparatus to the filter apparatus, and filtering the portion of the process water stream directed from the settling apparatus through the precoated filter elements to remove suspended solids particles to form a filtrate.

  • Publication number: 20140091022
    Abstract: This disclosure relates to making medical solutions. In certain aspects, a method is performed by a data processing apparatus. The method includes introducing liquid into a container that contains a dissolvable solid concentrate in a manner so that a layer of solution above the solid concentrate is maintained at a depth that allows the liquid introduced into the container to agitate the solution adjacent to the solid concentrate to cause mixing of the solid concentrate with the solution.

  • Patent number: 8685245
    Abstract: A method and an apparatus for separating suspended matter from liquid includes a concentrator filter that draws the liquid out of the suspension while the filter kept unblocked by a sparging filter that allows scrubbing of the concentrator filter by gas bubbles. This invention can be used to replace cross-flow filtration and centrifugation in the bioprocess industry and to reduce the volume of suspensions to concentrate the yield of the end product in the chemical industry.

  • Patent number: 8685335
    Abstract: A chemical release system. Implementations may utilize implementations of a first cartridge that include a body coupled with a cartridge head at a first end and coupled with an end plug at a second end where the cartridge head includes a through hole configured to engage with an annular flange in a main head. The body may have an internal cross section. The first cartridge may also include a flow restrictor plate disposed within the body between the first end and the second end where the flow restrictor plate is oriented substantially parallel to the cartridge head within the body, includes only one opening therethrough, and substantially conforms with the internal cross section of the body. The body may include one or more through holes in a side of the body located between the flow restrictor plate and the cartridge head.

  • Publication number: 20140034564
    Abstract: A filter media is described that employs multicomponent fiber material to form the filter media. The multicomponent fiber material is composed of two or more materials at least one of which is soluable in the application fluid that flows through and is filtered by the filter media to release additive(s) in a controlled manner into the application fluid. The additive(s) releases slowly throughout the filter application life.

  • Patent number: 8641895
    Abstract: A method and apparatus for recovering oil from oil-containing sorbents, such as drill cuttings obtained from drilling with an oil-based mud. The method includes peptizing the substrate with an acid reagent and direct thermal desorption with combustion effluent gases at high temperature under turbulent mixing conditions. Another method disclosed includes upgrading the oil in the substrate to improve one or more of the properties of the recovered oil relative to the oil in the substrate, such as, lower aromatics content, lower sulfur content, lower functional group content, higher saturates, higher viscosity, higher viscosity index, and any combination thereof. The apparatus provides for efficient recovery of oil from the substrate with a short residence time, high throughput, low residual oil content in the treated solids and/or high percentage of oil recovery. The apparatus may be transported to a remote location for on-site treatment of drill cuttings or other oil-containing solids.
