The majority of goods worldwide are transported by ships. In the next 5-10 years stricter regulations in the pollution from these vessels are coming into force. These include regulations for nitrogen oxides and carbon dioxide. At the same time more stringent regulations on fuel sulfur content are introduced. A consequence is that the ship engines, for a large part designed by MAN Diesel & Turbo A/S in Copenhagen, and in particular the operation of the ship engines will be changed. One of the major challenges in this context is to prevent ‘cold corrosion’ in the engines, which have proved to be a bigger problem under the changed circumstances. ‘Cold corrosion’ is a mixture of acid attack and mechanical wear in the engine, that has occurred because the sulfuric acid to a greater extent condense on the cylinder walls in the engines.
SULCOR is a project where DTU and MAN Diesel & Turbo has teamed up with international universities in a challenging work to understand and articulate the mechanisms underlying the formation and condensation of sulfuric acid in the engines, in order to sow ways to avoid the problems.
Project:
SULCOR - Sulfuric acid corrosion in large marine diesel engines
