Refrigerated Joule Thomson plants are economically designed for gas liquids recovery. These are simple systems to cool the gas to meet a dewpoint specification. JT plants are an economical choice for rich gas applications as, frequently, no residue compression is required. These may be used as a quick solution to gas liquids recovery while a larger plant is being constructed. Azota employs the use of different technologies to ensure the appropriate level of hydrocarbon dewpoint controlling, such as a JT plant, MRU plant, deep hydrocarbon dew pointing unit (DDP) or a turboexpander (an expander/compressor in a single package). Hydrocarbon dewpoint control is critical for transmission pipelines.
