1. desulphurisation by absorption systems,

2. If applicable, desulphurisation intervals shall also be considered based on manufacturer’s data

3. (7) Catalysts that are specific to refinery process applications (e.g. Catalytic and Hydro Cracking, Platforming, Hydrotreating and Desulphurisation).

4. Hydrotreaters specially designed for desulphurisation of gasoline, diesel cuts and kerosene and specially designed components therefore.

5. Benzene Saturation, Desulphurisation of C4–C6 Feeds, Conventional Naphtha H/T, Diolefin to Olefin Saturation, Diolefin to Olefin Saturation of Alkylation Feed, FCC Gasoline hydrotreating with minimum octane loss, Olefinic Alkylation of Thio S, S-ZorbTM Process, Selective H/T of Pygas/Naphtha, Pygas/Naphtha Desulphurisation, Selective H/T of Pygas/Naphtha

6. Even retrofitting of flue gas desulphurisation at the big coal stations would not make them more expensive than some gas burn.

7. The main CCPs are: Fly Ash, Bottom Ash, Boiler Slag, Fluidised Bed Combustion (FBC) Ash, Semi Dry Absorption Product, Flue Gas Desulphurisation (FGD) Gypsum.

8. Wet scrubbing systems provide the highest removal efficiencies for soluble acid gases of all flue-gas desulphurisation (FGD) methods with the lowest excess stoichiometric factors and the lowest solid waste production rate.
