Ammonia Plant Chemicals & Polymers
The source of the ammonia is generally compressor lube oil systems. These compressors often discharge small quantities of lube oil into the synthesis gas and recycle gas and, unless removed, the oil remains in the process often times resulting in off-specification ammonia. Another problem can exist in the C02 removal step of an ammonia plant.get price
