Recovery of carbon dioxide from carbon dioxide pellets production by compressing (5,6) and condensing (7) the carbon dioxide gas lost by the pellets production. Compressing the gas can be in one or two steps. The first step having a plurality of compressors (5) connected in parallel, the second step having a compressor (6) serially connected to the compressors (5) of the first step. The compressed gas is pre-cooled (9a,9b) downstream of the compressors (5) and further cooled (10a,10b) downstream of the compressor (6). At least one of the compressors(5,6) are a hermetic, a reciprocating or a scroll type compressor. Also at least one compressor is oil lubricated. |
