May I ask about the ratio of raw materials used for the carbonylation of methyl acetate to produce acetic anhydride?

Acetic anhydride is synthesized by the carbonylation of methyl acetate with carbon monoxide. The literature states that generally there is an excess of Co, with a molar ratio of Co to methyl acetate around 3. Does co have to be in excess? When using Aspen for simulation, problems always arise when there is an excess of CO. However, the process with an excess of methyl acetate can actually work. I would like to ask why this is the case ? ? :'(:'(
