3. Variations of this problem to discuss and solve: Every number in red could be changed You have a contract to transport exactly 250,000bbl/ day of oil to a refinery at an average pipeline temperature of 60E and 900 psia. The oil viscosity required for pipeline transportation is 300cp. You have unlimited quantities of an 11 API heavy oil ("HO") and a steady supply of 10,000bb/ day of a 28 API lighter oil ("LO") that you MUST use. However, even after mixing these two oils the viscosity is too high for pipeline transportation. One option is to dilute it even further with a 46API solvent ("S1"). Provide an estimate of the daily volume of solvent (S1) that you need to purchase such that the oil reaches target viscosity of 300cp. The following items guide you on what is required. Show your work very clearly and write down the final answers (all the ones I request) in the boxes provided. More variations to the problem to discuss and solve: Every number in red can be changed. You found out that your use of solvent was too high and making your business non-profitable. So you decided to cut the use of solvent volume by half and use a cheap gas of SG=0.56 instead to lower the oll viscosity to the regulated target of 300cp. The heavy oil has on API of 12 and the solvent used had an API of 48 . How much gas would you need to achieve this target viscosity, assuming that it can be dissolved at the pipeline pressure?
