SUMMARY:The recent Upgrades of Gas Treatment Plants in Europe
DESCRIPTION:The Gas Treatment Plants (GTP) of Acciaierie d'Italia has been just upgraded with new Claus plant, ramp up H2S/NH3 Desorption plant capacities and new chiller plant. The Arcerlormittal Gent (Belgium) has just started construction of new H2S/NH3 Desorption plant and new Claus plant. Both GTPs have a common goal, which is to reduce to low as possible the downtime of the desulfurization process by installing a 1+1 setups. This is state of the art of GTPs today. After the modification, Acciaierie d'Italia possess at least one standby unit in all plants of the GTP from Primary Gas Cooler (PGC) and up to Desulfurization. Acciaierie d'Italia has made itself completely weather independent and it is able to run on a hot south Italian summer a constant PGC outlet temperature. The GTP in Gent will continue to keep a clean COG even during boiler inspections or cleaning of internals owning to the new installation. 
The upgrading of an existing GTP (brown field installation) is counted to be one of the most difficult work in chemical engineering. That kind of work begins with a study to identify targets, concepts and last but not least budgets. At the pre-engineering phase, the tie-in points are investigated and identified by the engineers. The beigest challenge of engineering is to adapt a know process to the existing installation considering for example: flows, pressure and temperatures, accessibility, process control, local standards, modern standards, as well as minimize spare parts by trying to use the same wear parts as in the existing installation.   
The paper will present the arrangements of the GTPs and examples of engineers challenges, who developed solutions for some given specific difficulties with regard to brown field installations.
