  • Preventing ammonium chloride deposition
    Patent number: 4098675
    Abstract: Deposition of ammonium chloride from a gaseous stream as it is passed through a compression means is prevented by recycling to the compression suction a sufficient amount of the compression means discharge that has been heated by the compression operation to maintain the temperature of the gaseous stream above the deposition temperature for ammonium chloride at operating pressure. The invention is particularly useful in hydrocarbon hydrogen treating processes in which hydrogen recycle streams containing ammonium chloride or ammonium chloride-forming constituents must be recompressed before recycle to the hydrogen treating process.
