Limitations: The distance between the two units must not exceed 60 m in reality or the equivalent of 90 m taking into account pressure drops.The height of the liquid line in relation to the unit base must be less than 5 m. It is recommended to place a trap on the discharge line at the oil separator outlet, if this discharge line is horizontal for a distance greater than 5 m, at a height greater than the connection to the oil separators.

Limitations: The distance between the two units must not exceed 60 m in reality or the equivalent of 90 m taking into account pressure drops. Each 30 m level difference causes a 2% efficiency loss.
