Vertical separator is recommended if the well stream contains sand

A field study shows that the horizontal separator is failing to handle large liquid surges effectively. What design changes could be implemented to address this problem? (Select 2 correct answers)

• Increasing the length of the separator to increase retention time

• Switching to a double-barrel configuration

• Adding a secondary mist extractor to manage liquid slugs

• Reducing the gas inlet velocity to minimize turbulence

• Using a vertical separator to handle surge volume more efficiently
