  • Patent number: 10429361
    Abstract: A multi-dimensional liquid analysis system includes a flow splitter for separating mobile phase outflow from a first dimension liquid analysis system into first and second liquid split outlet flows. Volumetric flow rate control of the split outlet flows is provided by a flow control pump which withdraws one of the split outlet flows from the flow splitter at a controlled withdrawal flow rate to define the other split outlet flow rate as the difference between the outflow rate from the first dimension system and the withdrawal flow rate. In this manner, accurate and consistent flow division can be accomplished, which is particularly useful for multi-dimensional liquid analysis.

  • Patent number: 10118115
    Abstract: Some embodiments provide a centripetal air or gas cleaning apparatus for removing particulates from air or gas. The apparatus comprises an inlet, housing, impeller, a clean air outlet, and a particulate outlet. The housing has an inner conical surface. The impeller's rotation creates negative pressure towards the inlet that intakes particulate-pervaded air or gas into the housing. The rotation also induces an accelerating force that throws the particulate-pervaded air or gas against the outer walls of the housing. Here, the particulates separate from the air or gas, penetrate a high-pressure zone, and are ejected through the particulate outlet located in the high-pressure zone. The air or gas, having less inertia, deflects away from the high-pressure zone where it is then subjected to a centripetal force that drives the air or gas towards the center of the housing behind the impeller where it is ejected through the clean air outlet.

    Abstract: Rich natural gas is first compressed, then ambient air cooled and separated into lean natural gas, NGL and water. Hydrate formation during decompression of the lean gas is precluded by either heating the lean natural gas or mixing the lean natural gas with methanol or other additive before depressurization. Similarly, hydrate formation in the NGL is also precluded by either heating the NGL or mixing the NGL with methanol or other additive before depressurization. The NGL is conditioned for storage and transport in common propane tanks by a stabilizer or two-phase separator. The lean natural gas can be used for internal combustion, liquefied natural gas, compressed natural gas or liquid fuel processing.

  • Patent number: 8940159
    Abstract: The invention includes a method for the optimization of the soluble CO2 concentration in the aeration basin of an activated sludge system, which significantly improves the specific growth rate of the nitrifying bacteria. The result is a reduction in capital and energy costs for municipalities. The rate of nitrification is a product of the nitrifying bacteria biomass concentration and the specific growth rate of the bacteria. In the activated sludge system, the biomass concentration is maintained at high concentrations by reducing the wasting rate. The specific growth rate is a function of the ammonium concentration and the environmental conditions. Here, the inventors show that growth of nitrifying bacteria is inhibited when the soluble CO2 concentration is elevated beyond certain parameters. Elevated soluble CO2 concentration also reduces the pH, which also impacts the rate of growth of nitrifying bacteria.

  • Patent number: 8920658
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

  • Publication number: 20140367346
    Abstract: A reduced air hydrocyclone unit includes a hydrocyclone having a cylindrical section, a conical base having an underflow outlet formed in its apex, and an overflow outlet on an upper end of the cylindrical section. An underflow basin collects underflow material. Overflow material flows through an overflow line. An exhaust fan of the reduced air hydrocyclone unit withdraws from the overflow material in the overflow line a portion of an amount of air introduced through the apex of the hydrocyclone. A reduced air fluid system includes the reduced air hydrocyclone unit, a fluid tank in fluid communication with the overflow line of the reduced air hydrocyclone unit, and a reduced air hopper for mixing a solid material with a fluid contained in the fluid tank to form a slurry. A liquid barrier inlet of the reduced air hopper creates a liquid barrier to prevent air introduction into the slurry.

  • Publication number: 20140339178
    Abstract: A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

  • Publication number: 20140332454
    Abstract: A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

  • Publication number: 20140303579
    Abstract: A fluid-storing, filtering, and gas-discharging apparatus (2) comprising a fluid holder (21), a gas detector (23), and a filter (22). The fluid holder (21) has a protruding apex structure and comprises a fluid inlet and a fluid outlet. A gas-discharging pipe in communication with the outside is arranged on the protruding apex of the fluid holder (21). The gas detector (23) is arranged on the gas-discharging pipe. The filter (22) is fixed within the fluid holder (21) and is connected to the fluid outlet. The fluid-storing, filtering, and gas-discharging apparatus (2) uses the fluid holder (21) and the filter (22) to implement the storage and filtration of a working fluid, while at the same time, the fluid holder (21) having the protruding apex structure ensures complete discharging of gases mixed in the working fluid, thus achieves the goals of fluid storage, filtration, and gas discharge, and provides great reliability.

  • Publication number: 20140291258
    Abstract: The invention relates to a solution for enriching a liquid with oxygen. For this purpose, oxygen from the ambient air is introduced into the liquid by means of an injector and is partially dissolved in it. The liquid which leaves the injector, and which is laden with dissolved and undissolved gas components of the air, is then introduced into at least one degassing unit (2), which is connected downstream to the injector, for the removal of undissolved gas components that form bubbles in the liquid. According to the invention, the injector involves a multiple injector having at least two injector chambers (11, 12, 13, 14).
