Stream day 1,656 3.96 0.03 3.71
Note:
specific gravity of solvent =0.65
specific gravity of bitumen = 1.0
solvent loss per 1,000 volumes = (total solvent loss) X 1000
(solvent SAG * bitumen)
Request 26b Update the table to include solvent losses and bitumen production on a
volumetric basis.
Response 26b Table ERCB 26-3 and ERCB 26-4 provide volumetric data for site-wide solvent
loss for each material balance case with and without the asphaltene recovery unit.
