Allocation LPs are the most important part of the allocation procedure. Two refinery LP models are prepared, modeling AOC s and BOC s shares of the refinery for the reference month. For example, if the joint refinery had available crude distillation capacity of 200,000 barrels per day and the equity of the two participants is 60% and 40%, then AOC will have 120,000 bpd and BOC will have 80,000 bpd crude distillation capacity. Capacity of the downstream units will be similarly split up. The unit capacities used in the LP models are the available unit capacities during the month (not the actually used capacities, which could be less than that available for certain units). All unit yields, stream properties, blending, and product specifications are accurately modeled as per actual refinery operations during the reference month.
