Blast furnace flue dusts are a mixture of oxides expelled from the top of the blast furnace whose major components are iron oxides. They also contain zinc, silicon, magnesium and other minor element oxides in lesser amounts. The direct recycling of flue dust is not usually possible since it contains some undesirable elements (zinc and alkaline metals) that can cause operational difficulties in the blast furnace.

A concise and accurate methodology has been developed using well known software packages to predict the type and amount of inhibitor required during sudden depressurization of a system to prevent hydrate formation. The outlined procedure exhibits the P-T history of the system and hence the hydrate formation temperature profile.
