Patent number: 11052344Abstract: The application relates to a marine exhaust flue gas desulphurization system and method comprising a wet scrubber system for reducing the amount of sulphur oxides present in an exhaust flue gas of one or more diesel engines of a marine vessel using a scrubber liquid and being configured to run in an open and in a closed loop mode. A magnesium hydroxide slurry prepared by hydrolysis of magnesium oxide powder with water is contacted with the used scrubber liquid in order to clean the used scrubber liquid and/or to neutralize the acidity thereof.Type: GrantFiled: May 11, 2017Date of Patent: July 6, 2021Assignee: YARA MARINE TECHNOLOGIES ASInventors: Shyam Bahadur Thapa, Peter Strandberg

Patent number: 10563553Abstract: The present application relates to a spray tower for cleaning the exhaust gas from marine engines, wherein the spray tower, in installed position, is vertically positioned and comprises a central exhaust gas pipe for introducing exhaust gas into the spray tower through an exhaust gas inlet positioned at a proximal end of the central exhaust gas pipe, the central exhaust gas pipe being positioned at a bottom end of the spray tower, an exhaust gas outlet at a top end of the spray tower for withdrawing purified exhaust gas from the spray tower, one or more spray devices for providing scrubber liquid within the spray tower counter-current to the general exhaust gas flow, and at least two engine exhaust gas pipes being in fluid connection with the distal end of the central exhaust gas pipe. Furthermore, a method for reducing the amount of SOx in exhaust gas is described.Type: GrantFiled: June 23, 2017Date of Patent: February 18, 2020Assignee: Yara Marine Technologies ASInventors: Shyam Bahadur Thapa, Peter Strandberg

Publication number: 20190060825Abstract: The application relates to a marine exhaust flue gas desulphurization system for reducing the amount of sulphur oxides present in an exhaust flue gas of one or more diesel engines of a marine vessel and being configured for being able to run in an open and in a closed loop mode, and comprising when configured to run in closed loop mode. The system comprises a wet scrubber system comprising at least one wet scrubber arranged for scrubbing the exhaust flue gases originating from the diesel engine of the marine vessel using a scrubber liquid, thereby generating a used scrubber liquid, wherein the wet scrubber comprises one or more used scrubber liquid withdrawal pipes for withdrawing the used scrubber liquid from the wet scrubber.Type: ApplicationFiled: May 11, 2017Publication date: February 28, 2019Applicant: YARA MARINE TECHNOLOGIES ASInventors: Shyam Bahadur Thapa, Peter Strandberg

Patent number: 9776125Abstract: A vertical scrubber (1) for exhaust gas from a marine vessel is described. An exhaust gas tube (2) is substantially coaxially arranged through the bottom of a lower scrubbing chamber (3) and is released though an exhaust gas outlet (20) being coaxially arranged through the top of an upper scrubbing chamber (13). A lower scrubbing chamber deflection body (4) is arranged above the opening of the exhaust gas tube (2) for redirecting the exhaust gas towards the walls of the scrubber and create turbulent gas flow, where one or more lower chamber water injector(s) (6, 6?) is (are) arranged above the lower scrubbing chamber deflection body (4), to introduce scrubbing water, and where a lower chamber exhaust gas outlet (12) is arranged at the top of the lower scrubbing chamber (3) as a coaxial constriction, for withdrawing the partly scrubbed exhaust gas from the first scrubbing chamber and introducing the gas into the upper scrubbing chamber (13).Type: GrantFiled: February 21, 2014Date of Patent: October 3, 2017Assignee: Yara Marine Technologies ASInventor: Peter Strandberg
