Abstract
A tubular separation unit insertable into a caisson or tube for separating liquid from an upward flowing liquid/gas multi-phase stream, and comprising: a centrifugal flow-induced liquid separator having a multi-phase gas/liquid inlet, a liquid outlet, and a gas stream outlet; a liquid transfer conduit connected to the liquid outlet of the flow separator; and a pump for pumping liquid, disposed below the separator and including a pump liquid inlet connected to the liquid transfer conduit and through which liquid separated in the separator is received, and a pumped liquid outlet through which separated liquid is, in use, caused to flow selectively.

A tubular separation unit insertable into a caisson or tube for separating liquid from an upward flowing liquid/gas multi-phase stream, and comprising:
- a centrifugal flow-induced liquid separator having
- a multi-phase gas/liquid inlet,
- a liquid outlet, and
- a gas stream outlet;
- a liquid transfer conduit connected to the liquid outlet of the flow separator;
- and
- a pump for pumping liquid, disposed below the separator and including
- a pump liquid inlet connected to the liquid transfer conduit and through which liquid separated in the separator is received, and
- a pumped liquid outlet through which separated liquid is, in use, caused to flow selectively.
A method of removing liquid from an upward flowing liquid/gas multi-phase stream in a caisson or tube, including:
- separating liquid from the multi-phase liquid/gas stream centrifugally in a flow separator and passing it to an outlet;
- transferring the liquid through a conduit connected to the outlet of the flow separator to a pump disposed below the separator;
- and
- pumping liquid to a liquid outlet through which separated liquid is removed.
