II) Extraction (LS and SU). This step of the overall process is applied to extract the fish oil fraction from the AnR puree (3 kg) separating it from the other components (limonene, water, impurities). The EC of the process is 29.0 MJe/FU for the LS and 2.9 MJe/FU for the SU. For both LS and SU steps of the process, the mix of puree and limonene output is sent to the decanting step. For the SU process, the extract (limonene + AnO) is then directed to centrifuge and the wet sludge to the drying phase.
