Abstract: An apparatus using refrigeration for separating gases which liquify and separate at reduced temperatures from natural gas which remains gaseous at such reduced temperatures having a 1st inlet for delivering the gas to be separated into a pre-cool transfer vessel for transferring the heat from the gases to be separated as they are passed therethrough, a 1st outlet connected to the pre-cool transfer tube for discharging the gases to be separated; a 2nd inlet for delivering gases at reduced temperatures; a flow way container connected to the 2nd inlet for receiving gases at reduced temperatures and positioned about the pre-cooled transfer vessel for the gases at reduced temperatures to be in non-contacting conductive relationship for the transfer of heat from the gases to be separated in the pre-cool transfer tube.
