#### Abstract

Properly designed and implemented systems for regulating heat distribution and exchange systems can significantly improve the efficiency of the technological process by increasing its energy savings and thus reducing production costs. In particular, the introduction of a suitable system for controlling the heat exchanger network allows for more accurate and smoother maintenance of thermal technological parameters, e.g. Obtaining the highest outlet temperature through optimum distribution of the oil mass streams, which is the purpose of this engineering work. The implementation of this sectional model network heat exchangers (DRW) installation in MATLAB SIMULINKshared by the Mr Dr Inż. Marian Trafczyński. In the theoretical part are described methods reducing the effect of sludges on the regenerated heat stream in heat exchangers. The node of the oil-heating heat exchanger network has been specified before desalting on the basis of which the correctness and continuity of the simple and self-optimizing control methods with use of the dynamic model. In the design part first step was to prepare for the steady state of the ready-made model network of exchangers in Matlab. Through manual flowregulation, the resultsaresummarised in tables and graphs. Duringthe dynamic status test, the effects on the exhausttemperaturesweredisturbance of mass streams on the side of theshell and tubing, temperaturedisturbances, increasingvalues of flow and heat exchange resistance in time from the accumulation of sludgeschanges in environmentalconditions. After the calculation and introduction of the reinforcement for the PI regulator, the graphs show the benefits of using in regenerative heat exchanger networks, based on the PI regulator in Compared to the non-regulator system. In the last step of the study was to carry out the energy and economicbalance, whichconfirmedthatincreasing the amount of heat recovered from hot streamswouldtranslateinto a reduction in the amount of consumption and energy.
