A fluid purification and recovery system includes a buffer section configured to receive a fluid delivered from a process station, where the fluid pressure is maintained within the buffer section within a predetermined range and the fluid is maintained within the buffer section in at least one of a gas state, a liquid state and a supercritical state. The system further includes a purification section disposed downstream from the buffer section to receive the fluid from the buffer section, where the purification section includes at least one purification unit that separates at least a portion of at least one component from the fluid. In one embodiment, the fluid is maintained in at least one of a liquid state and a supercritical state in both the buffer section and the purification section. In addition, the buffer section delivers the fluid to the purification with minimal or substantially no fluctuations in pressure.
