Abstract
Process and system to produce nearly oil free ammonia using a rotary compressor with liquid injection from a separator tank where the liquid in the tank includes oil and liquid ammonia. The level of oil in the compressed ammonia leaving the separator is much lower than in conventional separators with coalescing elements, because the temperature is lower and there is less oil departure in oil vapor form.
