The DISPERS-ALL™ Ammonium Salt Dispersant Program is the Nalco Water solution to help mitigate the effects of ammonium chloride (NH4Cl) salt deposition in the top of FCC main fractionators, coker combination towers or CDU atmospheric towers.
When applied to an already fouled tower, the chemical is used to disperse and remove the deposits, thus cleaning the system to remove the immediate process bottleneck without the need to reduce unit feed rates or bring the unit down for cleaning. The salt dispersant can then be applied to the clean system on a continuous basis to prevent the further accumulation of these deposits.
