Abstract
In 2011, the world population passed 7 billions inhabitants. While this number
witnesses the success of humankind on earth, it also rises among other things questions about
food supply. Declining live stock in the wild, rising price of energy combined with climatic
change give a new economic potential for alternative sources of protein production.
Single cell protein (SCP) is protein produced by growth of micro organisms. Among these micro
organisms, Methylococcus Capsulatus is particular interesting as it can grow on either methane
or methanol and contains 70% protein. The U-Loop reactor is particular useful for production of
SCP by M. Capsulatus as it has good gas-liquid mass transfer capabilities and also the capability
to remove the signicant amount of heat developed by the reaction.
In this paper we describe an implementation of a model to simulate SCP production in the
U-Loop reactor. We report simulation results. In addition we design and compare dierent
regulatory control systems for regulation of SCP production in the U-Loop reactor. The
purpose of the regulatory control systems is to keep the process at a steady state and to
reject disturbances. We design and implement such control systems based upon PID and MPC
technology. In particular, we design these control systems such that they can be used as the
regulatory layer in a process control hierarchy and enable resilient transition from one operating
point to another. The optimal operating points are determined by the real-time optimization
(RTO) part of the control system.
