Publication number: 20210302935Abstract: A plurality of system control devices respectively include network interfaces for communicating with each other via a network. One of the plurality of system control devices functions as a master system control device, and the remaining system control devices function as slave system control devices. The master system control device transmits a control command to the slave system control devices by means of the network interface. The slave system control devices receive the control command by means of the network interfaces and supply an operation command to abatement devices in accordance with the control command. When unable to communicate with the master system control device, the slave system control devices either function as master system control devices or enter stand-alone operation mode.Type: ApplicationFiled: August 5, 2019Publication date: September 30, 2021Inventors: Kobayashi Kenichiro, Adrian Fisher, Christopher Peter Jones, Philip Carr

Patent number: 10618004Abstract: Provided is an abatement device that reduces an amount of drainage of circulating water. The abatement device lowers an average drainage flow of circulating water to a low flow, when a ratio of a concentration of silicon dioxide within the circulating water and a concentration of hydrogen fluoride within the circulating water is greater than or equal to a predetermined value at which hydrofluorosilicic acid can be produced, and raises the average drainage flow of the circulating water to a high flow higher than the low flow, when the ratio of the concentration of silicon dioxide within the circulating water and the concentration of hydrogen fluoride within the circulating water is less than the predetermined value.Type: GrantFiled: November 5, 2015Date of Patent: April 14, 2020Assignee: Edwards Japan LimitedInventors: Toshiki Yamada, Alexander Michael Pope, Alistair Bennett, Steven Barlow, Christopher Peter Jones

Patent number: 8475563Abstract: In a method of treating a gas stream, an aqueous scrubbing liquor is circulated through an essentially closed loop (20) comprising an electrochemical unit (48) for reducing the acidity of the liquor. A portion of the circulating liquor is diverted away from the closed loop (20) to a gas scrubbing unit (10). The gas stream enters the scrubbing unit (10), wherein an acid, for example HF and solid particulates, for example SiO2 particulates, within the gas stream dissolve in the diverted liquor. The diverted liquor is subsequently returned to the closed loop (20), and is replenished in the scrubbing unit (10) by fresh liquor diverted from the closed loop (20). A device (46) is provided for monitoring the acidity of the liquor at a location within the closed loop (20). The reduction in the acidity of the liquor by the electrochemical cell (48) is controlled depending on the monitored concentration.Type: GrantFiled: November 28, 2007Date of Patent: July 2, 2013Assignee: Edwards LimitedInventors: Philip Chandler, Christopher Peter Jones, Patrick Fletcher, Christopher Germain

Publication number: 20100147765Abstract: A method of treating a liquid waste containing target species is described, in which the liquid is first conveyed through a housing containing a catalyst for removing either a reducing agent or an oxidising agent from the liquid, The liquid is then conveyed to a reverse osmosis or nanofiltration membrane to obtain a retentate rich in the target species and a permeate lean in the target species. The retentate is returned to the liquid upstream from the membrane, whilst the permeate may be subject to further treatment, for example in a neutralisation plant.Type: ApplicationFiled: January 14, 2006Publication date: June 17, 2010Inventors: Christopher Peter Jones, Philip Chandler

Patent number: 6726828Abstract: Using a solution mining procedure, an ore (10) is treated with a solution of acetic acid and hydrogen peroxide so as to form a leachate containing lead ions. Lead ions (and other metal ions such as zinc and manganese) are stripped (22, 24, 26) by solvent extraction from the leachate to form separate aqueous solutions. The aqueous solution containing lead ions is treated electrochemically in the anodic compartment of a separated electrochemical cell (42) to form a precipitate of lead oxide. Manganese dioxide can be produced similarly (72). A precipitate of zinc hydroxide can be formed in the cathode compartment of a separated electrochemical cell (56). In the cells (42, 72) extracting lead ions and manganese ions, the cathode compartment is used to generate hydrogen peroxide (for use in making the leachant), either directly or indirectly.Type: GrantFiled: December 21, 2001Date of Patent: April 27, 2004Assignee: Accentus plcInventors: Andrew Derek Turner, Christopher Peter Jones
