Process simulation production modules

LiBrain (103) is a collection of software modules for automated combinatorial library design, including the incorporation of desirable pharmacophoric features and the optimization of the diversity of designed libraries. A Chemistry Simulation Engine module is trained by chemists to determine the suitability of reactants for a specified reaction, to recognize the risk of undesirable side reactions, and to predict the structures of the most likely reaction products, so as to circumvent major bottlenecks associated with automating the process.

The resulting optimization problem is solved using ILOG CPLEX [4], which generates a schedule for all major process steps, as well as the main material requirements for the production (optimal recipe definition for each batch). The schedule obtained is furthermore passed on to a crane movement simulation module, which... 

You are to simulate a partial condenser module that converts a vapor feed stream (SF) containing a single condensable species at temperature TF(K) to liquid and vapor product streams (SL, SV) in equilibrium at a temperature T(K). The process lakes place at a constant pressure P(atm). The compositions of the liquid and vapor product streams are related by Raoult s law (Equation 6.4-1), and the component vapor pressures are correlated with temperature by the Antoine equation. Table B.4. 

In this second alternative the use of standardized interfaces based on integrated product and process models enables the design and seamless interplay of several modules e.g. for the generation of simulation input data. The restructured scenario builds the basis for the integrated ID and 3D simulation where MOREX and BEMFlow were coupled (see Subsect. 5.4.5). 

Pressure drop unit are used to simulate hydraulic operations, as for example the pressure drop in a pipeline or in a distribution network. Adiabatic operation or heat transfer with the surroundings can be treated. In flowsheeting the module is generally tailored to simulate the transport of fluids in process plants. It can cover a large variety of physical conditions, as for example three-phase calculations in different flow regimes. However, special applications are better modelled by dedicated software, as the network of utilities (water and steam), or pipeline systems in oil gas production. 

Many companies require not only a modeler for geometrical elements but also application modules to integrate into their product development process and for computer intemeil imaging of the processes. Calculation modules and simulation software belong in this category. Such application modules must integrate with the modeler to form a functional entity (Figure 25). 

In many cases, the catalytic reactor model is used as a stand-alone unit in the design, simulation, and optimization of catalytic reactors. There are some typical cases in the petrochemical industry where the catalytic reactors dominate the production lines (e.g., the ammonia production line usually contains about six catalytic reactors representing almost 90% of the production line). In these cases, an evaluation has to be made in order to decide whether the reactor modules should be added to the flowsheet simulator or the few noncatalytic processes should be borrowed from the flowsheet simulator and added to a specially formulated flowsheet simulator of catalytic reactors forming the production line.
