Abstract
Contemplated gas-liquid separators and especially subsea gas-liquid separators have a main pipe with a plurality of descending branch pipes that are fluidly coupled to the main pipe and each other such as to allow disengagement of the gas into the main pipe while liquid and sand descend into the lower ends of the branch pipes. Sand accumulation in the lower ends of the branch pipes is preferably prevented by lateral serial flow of liquid and sand from one branch pipe to the next and use of a flush liquid that is drawn from one or more branch pipes.
