Patent number: 9289715Abstract: An improved flue gas scrubbing apparatus and method are disclosed. The flue gas scrubber comprises a double-pipe or a two-pipe system whereby flue gas enters the system. Scrubbing is accomplished by interaction between the flue gas and base in a pre-injection zone, followed by further reaction in a primary injection zone and passage through a cyclone unit. In preferred embodiments of the invention, it comprises a bypass system by which flue gas is automatically exhausted directly to the atmosphere in case of a system failure. The gas exhausted from the apparatus following scrubbing meets or exceeds international emissions standards.Type: GrantFiled: July 25, 2011Date of Patent: March 22, 2016Assignee: CLEAN MARINE ASInventors: Nils Høy-Petersen, Johan Ivar Ervik, Riki Canari

Patent number: 9157360Abstract: A method for low-contamination generation of energy comprising: (a) forming a gas mixture by mixing a treated gaseous effluent stream and air; (b) introducing the gas mixture and fuel at a given gas to fuel ratio into at least one diesel engine (3); (c) burning the fuel in the diesel engine to generate energy and a flue gas stream comprising particulate matter (PM), and nitrogen oxides (NOx); (d) treating at least a portion of the flue gas stream with an aqueous stream in a cyclone unit (27) comprising a housing defined by a cylindrical peripheral wall (2) and provided with at least one inlet opening (10) for receiving flue gas and at least one inlet opening for receiving fluids thereinto and with at least one swirling means, whereby a treated gaseous effluent stream and an aqueous effluent stream are formed; (e) emitting a portion of the treated gaseous effluent stream to form an emitted portion; (f) using a portion of the treated gaseous effluent stream to form the gas mixture, and (g) repeating steps (a) tType: GrantFiled: November 23, 2009Date of Patent: October 13, 2015Assignee: Clean Marine ASInventors: Nils Christian Hoy-Petersen, Aharon M.

Patent number: 8524180Abstract: The invention provides a process for minimizing the emission of particulate matter and precursors thereof from a flue gas stream of an engine comprising particulate matter and precursors thereof and at least one gaseous component. The process includes the steps of obtaining a flue gas stream of an engine comprising particulate matter and precursors thereof; increasing the moisture content of the stream by contacting it with a first aqueous medium in an amount and at a temperature at which at least 50% of the water content of the first aqueous medium is evaporated; whereby a moisture laden gas stream, optionally containing suspension droplets, is formed; cooling the moisture laden gas stream whereby suspension droplets are formed; and applying a centrifugal force to the moisture laden gas stream and to the suspension droplets to effect the swirling thereof, whereby a treated gaseous stream and an aqueous stream are formed.Type: GrantFiled: October 1, 2009Date of Patent: September 3, 2013Assignees: Vortex Ecological Technologies Ltd., Clue AS, Clean Marine ASInventors: Riki Canari, Aharon Eyal, Nils Christian Hoy-Petersen, Matitiahu Fichman, Carl Christian Hauge, Carmi Raz

Publication number: 20120275980Abstract: A method and apparatus for diluting a solution of an alkali metal hydroxide (MOH) by using seawater or any other aqueous solution are disclosed, in which a concentrated MOH solution and seawater contact opposite sides of a membrane adapted to transmit water but not other molecules, thus creating a diluted solution of MOH and concentrated brine. Additional embodiments include means for limiting fouling of the system by removing Ca and Mg from the seawater by precipitation or reaction with a flocculant. Means and methods for adapting the method and apparatus for use in a flue gas desulfurization system are also disclosed.Type: ApplicationFiled: December 16, 2010Publication date: November 1, 2012Applicant: CLEAN MARINE ASInventors: Riki Canari, Johan Ivar Ervik
