ShareSummary
Ammonia is practically insoluble in the oils currently used. In large installations this is no big problem, as accumulated oil can be eliminated periodically. Doing this would be impractical, however, in smaller installations. The goal of the research is therefore to find an oil suitable for use with ammonia in smaller plants. Initial results show possibilities of spontaneous oil return in ammonia plants with dry-expansion evaporators, as is the case in R22 plants.
