Glycol Dehydrator | Exterran

Wet gas enters the bottom of the absorber tower and ascends through a mist extractor where fine liquid particles are removed. As the gas rises through the tower’s packing or bubble cap trays, water is absorbed by descending lean glycol (water removed through regeneration process), which is continually pumped to the top of the tower.

Review of Sand Production Prediction Models

Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount over a short period of time, resulting in ...
