A 9.5 API bitumen produced from an oilsands production facility on average contains 2240 g/g salts on entering the bitumen upgrader facility. The nameplate capacity of the upgrader is 67,000 barrels per day. The front-end of the upgrader has a desalting unit, which is followed by an atmospheric distillation unit (ADU). The desalter has a stage efficiency of 88 wt% salt removal per stage. 1.1 If a two-stage desalter is used, what is the salt content in the bitumen going to the atmospheric distillation unit? (Report your answer as integer value in units of g/g) 1.2 A modification of the desalter improved the desalting somewhat so that the bitumen leaving the desalter has only 28 g/g salt. Empirical evidence based on past upgrader performance indicated that 14% of the salt accumulates in the preheater section of the ADU. What is the salt accumulation rate in the preheater? (Report your answer to one decimal in units of kg/h)
