The reactor scheduling module of ORSOFT Dynamic Flow Chart Simulation provides dialogue-oriented planning functions for daily plant operations in refineries. Plant facilities such as MTBE plants, C2-, C3-, C4 crackers and pipelines can be scheduled.
The reactor scheduling tool simultaneously considers resource allocation, material flow, throughput and qualities as well as material parameters which are altered during the process. Thus, the ORSOFT solution provides additional features and functional enhancements for the SAP ERP / SAP S/4HANA model. Throughputs and product allocations in the reactors are adjusted according to changing customer requirements and/or altered chemical compositions of input substances. As a result, effects on tank filling levels are calculated and, in a more detailed view, effects on substance compositions in subsequent resources are also foreseeable.
Graphical User Interface (GUI)
Context menus provide access to every GUI element and SAP transaction which are related to associated tanks and reactors. E.g. for a reactor, users can call browsers where process orders with related throughputs and allocation rules are listed. Future inputs and outputs, product qualities for each separate day or information on SAP ERP or SAP S/4HANA classifications are available for each tank.
Users can explore the solution using the graphic flow chart. Later, when familiar with handling, they will use GUI elements of the hierarchical planning cockpit instead.
Planning Throughputs and Mixing Ratio of Material Flows in Reactors
The cockpit section "Production" shows reactor information (see picture, click to enlarge). In the example given here, the amount of material input is calculated. Inputs from two different tanks with two different raffinates for butadiene extraction can be modified. Alternatively, throughput and mixture ratio of the input substances can be adjusted instead of changing the input flows.
The cockpit section "Indicators" (see above) shows key figures of effectiveness for each reactor. It becomes very clear that a continuous utilization of the entire system’s capacity of 100% can hardly be achieved.
