The key to minimizing ammonium chloride salt build-up in the Stabilizer system is to minimize organic nitrogen in the feed. Salt accumulation is generally either in the Overhead Condensers or on the trays in the top portion of the tower. The most commonly used method to dispose of the salts is on-line water washing. We have heard of at least one refiner using a NALCO salt dispersant with success.
