Optimalization of sorbent feeding in the dry method of flue gas desulfarization

The swiftly developing sea transport contributes to a considerable increase of fuel usage in the international shipping, which results in the escalation of toxic compounds emitted into the atmosphere. It is followed by the constantly heightened requirements limiting those emissions. In the case of sulfur oxide emission, inside of SECA (Sulfur Emission Control Area), the maximum content of sulfur in the shipping fuels used on the territorial seas was reduced to 0.1% per mass unit, but at the same time the legislator allows the ability to use a desulfurization installation working in a closed configuration. One of the desulfurization methods fulfilling those requirements is the dry method of desulfurization. In this paper are presented the results of research conducted on this very topic in the Department of Marine and Land Power Plants. The focus is the presentation of formulated characteristics of adsorbent feeding by an injection system dedicated to the dry method.
