  • Patent number: 10358364
    Abstract: A method of manufacture of high-solids hydroxide slurries from caustic calcined carbonate powder is described, whereby the properties of the slurry are its low resistance to shear thinning to facilitate transport, a high stability for transport and storage, ease of reconstitution after long periods of storage, and, as required, a high concentration of chemically reactive species at the particle surface. The method achieves these specifications by mixing caustic calcined carbonate or hydroxide powder with water in an insulated reactor vessel, and agitating the slurry sufficiently such that the hydration reaction causes the water to spontaneously boil, such that the remaining hydration proceeds spontaneously under the fixed conditions of boiling through the water loss. The mixing process is preferably carried out by a shear pump. A viscosity modifier, such as acetic acid, is used to thin the slurry to enable the mixing system to maintain uniform mixing.

  • Patent number: 6571817
    Abstract: A pressure proving gas valve insures safe and efficient operation of a fuel-burning appliance by monitoring combustion air pressure and appropriately controlling the valve based upon this air pressure. An air pressure sensor is incorporated into a pressure proving valve housing itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber unless appropriate combustion air pressure is sensed. Further, by monitoring the actual air pressure, additional control capability is provided. That is, a variable speed blower associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.

  • Publication number: 20030013783
    Abstract: High concentration drag reducing agents may be prepared by microencapsulating and/or macroencapsulating polymer drag reducing agent. The encapsulation may be performed prior to, during, or after the polymerization of monomer into effective drag reducing polymer. If encapsulation is done before or during polymerization, a catalyst may be present, but little or no solvent is required. The result is very small scale bulk polymerization within the capsule. The inert capsule or shell may be removed before, during or after introduction of the encapsulated drag reducer into a flowing liquid. No injection probes or other special equipment is expected to be required to introduce the drag reducing slurry into the liquid stream, nor is grinding (cryogenic or otherwise) of the polymer necessary to form a suitable drag reducing agent.

  • Patent number: 6024111
    Abstract: In a process for hydraulic transport of bulk material from a receiving site to a remote location via a conveying pipeline, a dispersion is prepared from bulk material and a liquid, and conducted into a feed pump which has a pressure side in communication with the entry into conveying pipeline, whereby a fraction of the liquid is withdrawn at a location between the pump and the entry into the conveying pipeline. Suitably, either the volume flow of the withdrawn fraction of the liquid represents a manipulated variable which is changed in dependence on a controlled variable constituted by the volume flow through or pressure in the conveying pipeline, or/and the dispersion is produced upstream of the feed pump from a controllable bulk material stream and controllable liquid amount, whereby the amount of liquid may also include at least a fraction of the liquid withdrawn from the pressure side of the feed pump.
