This invention relates generally to a separation process in which a multi-component feed stream is introduced into a separation system that operates under solids forming conditions for at least one of the feed stream components. The freezable component, although typically CO.sub.2, H.sub.2 S or another acid gas, can be any component that has the potential for forming solids in the separation system. The multi-component feed stream is introduced into a separation system, at least a portion of which operates under solids forming conditions for at least one component of the feed stream. A vapor stream is withdrawn from an upper region of the separation system and compressed to a higher pressure stream. At least a portion of the compressed stream is cooled and then expanded to a lower pressure to further cool the compressed stream. At least a portion of the expanded stream is returned to the separation system, thereby providing refrigeration to the separation system.
A separation process comprising the steps of:
A process of separating a multi-component feed stream containing at least methane and a freezable component having a relative volatility less than that of methane, comprising the steps of:
A separation process comprising the steps of:
A separation process comprising the steps of:
A separation process comprising the steps of:
A separation process comprising the steps of:
A separation process using a separation system that comprises a first distillation column and a second distillation column, said first distillation column comprising a distillation section and a freezing zone above the distillation section, said second distillation column comprising a distillation section, said process comprising the steps of:
