Abstract
By appropriately designing a flash tube, spraying of abrasive slurry on the vessel walls and impinging the multiphase jet on bottom of the vessel are minimized. By appropriately designing a flash vessel, once the flash tube has been designed, a slurry pool is provided having a volume that is sufficient to dissipate the flash tube exit jet momentum and the mass of entrained carryover products exiting from the vapor outlet is minimized.
