Pilot-plant automation for catalytic hydrotreating of heavy residua
Abstract
The research and development center of Chiyoda Chemical Engineering and Construction Co. has been investigating the catalytic hydrotreating of heavy residua via pilot plant technology. Chiyoda's 52 microreactors. bench-scale test units and pilot plants are each used depending on the purpose of the process development for heavy oil upgrading. The microreactors are effective for catalyst screening. Heavier fractions such as asphaltene and sludge materials often disturbed steady state operation. Many unique devices for the test units and improvement of operation procedures make extended operation easy as well as increasing reliability. The computerized data acquisition and data filing systems minimize the work not only for operators but for all research personnel. Currently, about 40 pilot plant units are continuously running while the others are in preparation. Fully automated operation requires only three for data checking at night. In the daytime, seven operators take care of feed supply, product removal and condition changes. For start-up and shut-down, one operator can handle three microreactos, but only one bench-scale unit or pilot plant. Planning is underway for an improved start-up system for the pilot plants using personal computers. This system automatically sets feed rate and raises reactor temperature. (JMT)
