Abstract
A method for cleaning a reactor, the method including circulating a fluid inside the reactor, pumping the fluid from the reactor into an inlet of a tank cleaner, and removing solids from the fluid to produce a clean fluid. The method further includes transferring the clean fluid to the reactor and transferring pneumatically the removed solids to a pressurized vessel. Also, a method for transferring spent granular material, the method including providing a vacuum system disposed at a hydrocarbon production site to remove spent material from a reactor, transferring the spent material through the vacuum system into a pressurized vessel, and conveying pneumatically the spent material from the pressurized vessel to a second pressurized vessel.
