Introduction The use of fossil fuels as an energy source results in the emission of a complex mixture of gases, aerosols and particulate matter to the atmosphere. Legislation to limit these emissions has been implemented both on land and at sea in order to safeguard human health and the environment. However, such legislation began to be implemented earlier for land-based emissions than for emis...

A seawater spray scrubber was set up and tested with focus on desulfurization of marine engine exhaust gas. Experimental tests were carried out simulating typical exhaust conditions of a marine diesel engine burning heavy fuel oil, and using real seawater. Different flue gas flow rates, seawater flow rates, and SO2 concentrations were tested. Liquid-to-gas ratios were in the range 1-10 x 10. A ...

In 1932 (1) the author published a method for determining methionine in proteins based on the recovery of methyl iodide. Alcoholic silver nitrate was used as absorbant and the excess of silver nitrate was titrated with thiocyanate after filtering off the silver iodide. This method was quite satisfactory and has been used recently by Barritt (2) for the determination of methionine in wool. Certa...
