Separator technology reduces refinery operating costs and downtime

A US refining company contacted us to discuss a separation problem in the feed to an alkylation process. Caustic entrainment from their selective hydrogenation unit was poisoning the hydrofluoric acid catalyst in the alkylation unit. The continuous phase feed to the alkylation unit consisted of ~180m3/hr of mixed C4 hydrocarbons, mainly butanes and butylenes, with varying levels of 10 – 20% caustic solution entrained as a dispersed aqueous phase. Sulzer was commissioned ...
