Patent number: 11045742Abstract: A purification module configured to separate and purify a liquid solution is provided. The purification module may include a vessel configured to receive a predetermined amount of a liquid solution. The purification module may also include a heating apparatus configured to apply heat to the vessel at a temperature of a first boiling point, and a column apparatus configured to separate the liquid solution into a first liquid and a second liquid and purify the first liquid and the second liquid to a determined purity level. The column apparatus may include a first heating chamber, a second heating chamber, and a distillation chamber. The distillation chamber may be located between the first heating chamber and the second heating chamber. The first heating chamber and second heating chamber may be configured to receive a heat transfer liquid to apply heat to the distillation chamber at the temperature of the first boiling point.Type: GrantFiled: November 22, 2019Date of Patent: June 29, 2021Assignee: Jaxon Technologies, LLCInventors: Chris Wunz, Roshan Jeet Jee Jachuck, Sam Gorton

Patent number: 7115235Abstract: A reactor including a rotatable disc (3) having first (5, 19) and second (20, 30) surfaces. Reactant (15) is supplied to the first surface (5, 19) by way of a feed (4), the disc (3) is rotated at high speed, and the reactant (15) forms a film (17) on the surface (5, 19). As the reactant (15) traverses the surface (5, 19) of the disc (3), it undergoes chemical or physical processes before being thrown from the periphery of the disc (3) into collector means (7). Means for supplying a heat transfer fluid (35) to the second surface (20, 30) are also provided so as to allow the first surface (5, 19) and hence the reactant (15) to be cooled or heated.Type: GrantFiled: February 17, 2000Date of Patent: October 3, 2006Assignee: Protensive LimitedInventors: Colin Ramshaw, Roshan Jeet Jee Jachuck, Michael Jones, Ian Henderson

Publication number: 20060194934Abstract: A method of conducting polymerisation reactions on a rotating surface reactor which allows substantially increased conversions (up to around 99%) to be achieved without a corresponding increase in polydispersity as would be expected as a result of the Trommsdorff-Norrish effect. The rotating surface reactor serves to disentangle and/or stretch growing polymer chains so as to result in better control over polymerisation kinetics.Type: ApplicationFiled: May 9, 2006Publication date: August 31, 2006Inventors: Roshan, Jeet, Jee JACHUCK, Michael Jones, Ian Henderson

Patent number: 7074353Abstract: A method of manufacturing particles, especially nanoparticles, by way of precipitation from solution on a rotating surface (1) of a rotating surface reactor is disclosed. Nanoparticles with a tight size distribution may be manufactured in bulk and without the problems of agglomeration that are associated with traditional stirred-tank reactors. Use of a rotating surface reactor allows precipitation of nanoparticles from viscous, supersaturated solutions by way of homogeneous nucleation aided by strong micromixing.Type: GrantFiled: July 22, 2002Date of Patent: July 11, 2006Assignee: Protensive LimitedInventors: Roshan Jeet Jee Jachuck, Stuart Cook

Patent number: 7014820Abstract: A reactor including a rotatable disc (3) having a region (13) in an upper surface (5) thereof. Reactant (15) is supplied to the region (13) by way of a feed (4), the disc (3) is rotated at high speed, and the reactant (15) moves from the region (13) so as to form a film (17) on the surface (5). As the reactant (15) traverses the surface (5) of the disc (3), it undergoes chemical or physical processes before being thrown from the periphery of the disc (3) into collector means (7).Type: GrantFiled: February 15, 2001Date of Patent: March 21, 2006Assignee: Protensive LimitedInventors: Colin Ramshaw, Roshan Jeet Jee Jachuck, Michael Jones, Ian Henderson

Patent number: 6977063Abstract: A reactor including a rotatable disc (3) having a surface (5) onto which reactant (15) is supplied by way of a feed (4). The disc (3) is rotated at high speed, and the reactant (15) spills over the surface (5) so as to form a film (17). A shear member (18, 20) is mounted close to the surface (5) so as to contact the film (17) during operation of the reactor, thereby applying a shearing force to the reactant (15) so as to aid mixing.Type: GrantFiled: February 17, 2000Date of Patent: December 20, 2005Assignee: Protensive LimitedInventors: Colin Ramshaw, Roshan Jeet Jee Jachuck, Michael Jones, Ian Henderson

Patent number: 6972113Abstract: A reactor including a rotatable disc (3) having a surface (5) onto which reactant (15) is supplied by way of a feed (4). The disc (3) is rotated at high speed, and the reactant (15) spills over the surface (5) so as to form a film (17). The surface (5) is provided with features to enhance its surface area, such as a metal mesh (60), thereby helping to increase the residence time of the reactant (15) on the surface (5) and to help mixing.Type: GrantFiled: February 17, 2000Date of Patent: December 6, 2005Assignee: Protensive LimitedInventors: Colin Ramshaw, Roshan Jeet Jee Jachuck

Patent number: 6858189Abstract: A reactor including a rotatable disc (3) having a trough (13) in an upper surface (5) thereof. Reactant (15) is supplied to the trough (13) by way or a feed (4), the disc (3) is rotated at high speed, and the reactant (15) spills out of the trough (13) so as to form a film (17) on the surface (5). As the reactant (15) traverses the surface (5) of the disc (3), it undergoes chemical or physical process before being thrown from the periphery of the disc (3) into collector means (7).Type: GrantFiled: February 17, 2000Date of Patent: February 22, 2005Assignee: Protensive Limited (a company incorporated in England)Inventors: Colin Ramshaw, Roshan Jeet Jee Jachuck, Michael Jones, Ian Henderson
