Author Posts December 28, 2005 at 6:55 am #4270 Anonymous The designed feed for DCU in this refinery is vacuum residue with cut point 565C+ from VDU. We plan to feed this DCU with atmospheric residue(cut point 343+) from CDU. The throughput will be only 50% of the designed rate. Is there any risk for executing this process change? .
