A 2000-MW electric generating station burns 278 tonnes of residual fuel oil per hour. The fuel contains 2.6% S and 1.2% ash. The station is equipped with particle, sulfur dioxide, and nitrogen oxide emission control systems. The particle collector must operate at efficiencies exceeding 98% because the ash is valuable for its vanadium content. The sulfur dioxide removal device operates at a normal efficiency of 80%.

A) Estimate the hourly SO2 and particle emissions from the station.
B) What type of particle collector would you use at the station? Give three reasons for choosing this type of collector.
C) What type of SO2 removal device before (in front of) or after (following) the particle collector would you use?
D) How would you control the nitrogen oxide emissions?
