Methods and apparatus for mechanical separation of co2

A mechanical separator for separating liquid CO2 from a 2 phase feed stream, comprising:

• a housing defining an enclosed chamber within the housing, said chamber arranged to receive the 2 phase feed stream;
• a baffle within the chamber, said baffle arranged to rotate relative to the housing and positioned such that the feed stream is received at a central portion of said baffle;
• said housing including a liquid phase outlet proximate to a periphery of the chamber and a gas phase outlet proximate to a central portion of the baffle;
• and
• wherein rotation of the baffle is arranged to accelerate a liquid phase of the 2 phase feed stream to the periphery of the chamber for outflowing through the liquid phase outlet with the gas phase at said central portion for venting through the gas phase outlet.
