Vertical compressor suction drum

EXHIBIT 5-1 Typical Vertical Compressor Suction Drum... 

Examples of vapor/liquid separator are (I) amine flash drum, where majority of inlet flow is liquid with very little flashed vapor, (2) compressor suction knock out drum or ftiel gas knock out drum, where the majority of inlet flow is vapor with very little carryover liquid, (3) hot separator in hydrotreater, where considerable amount of vapor and liquid are in the inlet flow. In general, vapor/liquid separator can be either vertical or horizontal. 

However, compressor suction knock out dnim or gus knock out drum is always a vertical vessel, since less plot area is required.
