Use of 254 SMO (UNS S31254) austenitic stainless steel in tall oil applications
In tall oil distillation, as in virtually all systems in pul and paper mills, there is a long term trend to increasingly aggressive corrosion conditions. Factors contributing to this trend include increasing plant size, steps taken to comply with effluent regulation, and the ongoing effort to increase production efficiency. It has long been known that a 6Mo stainless steel or nickel-base alloy resists the very aggressive conditions in the tall oil distillation column, but no such grade has been available for economical construction. The availability and favorable experience with a 6Mo austenitic stainless steel, S31254, in pulp bleaching service suggest potential savings in maintenance costs and in increased production efficiency. This paper characterizes S31254 and discusses field experience in selection of advanced stainless steels for tall oil distillation service.
