(83b) Development of the Exhaust Gas Treatment System for Reduction of Particulate Matter from Diesel Engine Exhaust Gas

Lab & pilot tests of the process to remove the PM(particulate matter) in the exhaust gas from marine diesel engine had been performed as a countermeasurement to the regulation of PM, which is scheduled to apply in 2007 by IMO(International Maritime Organization). The design & operating conditions for PM removal efficiency higher than 70% were verified at the lab-scaled test facility of the single cylinder engine. On the basis of the result of lab test, pilot test reactor of 750 m3/hr, 1/20 scale for 100% load diesel engine of HHI, was established at the PPS(Packaged Powet Station) test engine. The PM removal efficiency and pressure drop according to the operating conditions, such as gas velocity, duration time, depth of depositor, were tested and the duration time for depositor, time required for 90mmAq pressure drop, were verified. Also, regeneration test of depositor according to the regeneration conditions, that is time and temperature, were carried out to establish the optimum regeneration conditions in commercial operation.
