摘要:
A reversely subliming substance is efficiently collected on a commercial scale from a gas containing the substance. This is achieved by introducing the gas containing the substance into a shell-and-tube collecting apparatus by controlling the resistance offered to the gas during the passage thereof through the cooled tubes retained inside the collecting apparatus or by utilizing gas-introducing tubes excelling in dispersibility.
