Patent number: 9011575Abstract: This invention proposes a method of removing pollutants from high temperature gases prior to their introduction in to a heat exchanger of a steam generating boiler within a power generation system. The method places a filter system (100) in a hot gas flow path upstream of a waste-heat boiler. The filter system has at least two banks of substantially hollow elongate filters (110), each of which filters particles from the gas flow as it flows from an external surface thereof to an internal surface thereof. Valves (104, 106) enable each bank of filters to be isolated from the hot gas flow path. The method included periodically isolating at least one bank of filters while passing hot gasses through at least another of the banks of filters, and cleaning the isolated bank of filters. After cleaning the filters (110) lime is injected into the flow path so that it coats the outer surface of the filters (110) to produce a loose lime coating thereon.Type: GrantFiled: April 7, 2011Date of Patent: April 21, 2015Assignee: Chinook Sciences, LimitedInventors: Rifat Al Chalabi, Ophneil Henry Perry

Patent number: 8524187Abstract: A VOC treatment apparatus is provided for treating substantially opaque VOCs and comprises a processing chamber (24) in which VOCs are treated; and a solar energy introducing device (8). The solar energy introducing device (8) comprises a tubular structure having a first end located external to the processing chamber (24) and having a first inlet (14) through which concentrated sunlight is received and a second inlet (16) through which a flow of substantially optically transmittant gas is received. The solar energy introducing device (8) has a second end (18) that opens into the processing chamber (24) and terminates in a nozzle providing an outlet for the substantially optically transmittant gas and the concentrated sunlight. In use the optically transmittant gas exits the second end of the device in a jet to create an optically transmittant zone in the substantially opaque VOCs within the processing chamber (24), in which zone the sunlight can travel.Type: GrantFiled: January 24, 2011Date of Patent: September 3, 2013Assignee: Chinook Sciences LimitedInventors: Rifat Al Chalabi, Ophneil Henry Perry

Publication number: 20130199338Abstract: A metal reclaiming system and method for reclaiming metal from scrap material is provided. The system has a furnace (12) and a controller (106) for controlling operation of the system. The controller (106) operates the metal reclaiming system in a first operating mode in which the furnace (12) is operated at a first temperature in the range of 350° C. to 550° C. to incinerate pollutants and drive off volatile organic compounds (VOCs) from the scrap material without melting the metal. The controller (106) is operates the metal reclaiming system in a subsequent operating mode in which the furnace (12) is operated at a further, higher temperature to melt metal in the said scrap for reclaiming.Type: ApplicationFiled: February 4, 2011Publication date: August 8, 2013Applicant: Chinook Sciences, LimitedInventors: Rifat Al Chalabi, Ophneil Henry Perry

Publication number: 20120186502Abstract: A processing container (100) is provided for processing waste material. The processing container has a housing (150) and a processing zone (152) in said housing for containing waste material to be processed. The housing (150) has a portion (154) directed inwardly of said container to form an opening (160) for the charging and discharging of said processing container. The processing container is rotatable about its axis in a first direction to enable charging of said container through said opening and in a second opposite direction to enable discharging of said container through said opening. The processing chamber is used in an apparatus (10) for processing waste material. The apparatus also includes an oven (12) that contains the processing chamber (14); a gas inlet (200) for introducing said hot gasses into the oven; and a gas outlet (202) for extracting gas from said oven. The processing container (100) is mounted for rotation in said oven.Type: ApplicationFiled: August 27, 2010Publication date: July 26, 2012Applicant: CHINOOK SCIENCES, LIMITEDInventors: Rifat Al Chalabi, Ophneil Henry Perry, John Henry Turner
