Alkylation Unit effluent streams typically contain trace levels of fluoride based contaminants such as free hydrogen fluoride and organic, or combined fluorides. These contaminant species must be removed in order to avoid corrosive effects and meet product specifications.
The standard industry practice is to make use of fixed bed adsorbers referred to as defluorinators.
UDEC’s spherical promoted fluoride adsorbent is tailored for optimum activity towards organic fluoride decomposition and hydrogen fluoride removal from propane, butane and alkylate streams.
The physical and chemical properties result in higher fluoride loadings and longer alumina life.
The promoter maximizes fluoride loading capacity with significant reduction in coking tendency.
