Why is the oil compressed together with ammonia in the ammonia tank compactor? What are the advantages and disadvantages of this?

Please ask an expert to provide a detailed explanation!
Small chillers generally use screw compressors; oil is added for lubrication and sealing to prevent dry friction, and it’s inevitable that the sealing oil contained in the ammonia gas seeps in
I wonder what the disadvantages are!
Since it is a screw compressor, the ammonia at the compressor outlet contains a large amount of lubricating oil. Although most of this lubricating oil has been removed by the oil separator, trace amounts of it remain in the outlet ammonia, which reduces the quality of the liquid ammonia. Screw compressors have low efficiency and high energy consumption. The power of each individual unit is low, resulting in a large floor area required for the entire ice plant.
