AL-ALI* Ras Tanura Refinery, SAUDI ARAMCO, Saudi Arabia *Department of Chemical Engineering, King Fahd University of Petroleum & Minerals KFUPM, Dhahran, Saudi Arabia Email: [email protected] ABSTRACT The flow in a radial flow fixed bed reactor (RFBR) The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated.

Fixed-bed reactors have been a mainstay of catalytic reaction processing for many decades. While easy to construct and implement, they suffer from a number of shortcomings when designing a continuous flow process (1, 9, 13–15).Pressure drop (back-pressure) across a fixed-bed reactor is a major concern when developing a flow process, especially with a viscous medium. They can be loaded into the reactor in several ways: as a single bed, separate shells, or in tubes. Catalysts are typically made from nickel, copper, osmium, platinum, and rhodium. The catalysts shown below are made of precious metal on 3.175 mm ceramic beads and are used in an electric catalytic oxidizer that treats air streams contaminated with volatile organic compounds (VOCs).
