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: 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
