How to Simplify Chemical Process Calculations

The main purpose of simulation is to simplify chemical process calculations. All simulations and process chemical calculations are very difficult and complicated to compute because they involve non-linear differential equations. It becomes very difficult to solve by analytical or numerical methods that are pure mathematical methods. The best way to simplify the chemical process technology calculation is to try to understand the phenomenon and then allocate this phenomenon to the level of accuracy required to solve the problem. The best and simplest example is flow. If I need to manufacture a material that the use of this material is for instance, some kind of oil or lubricant, and it is not so important to have the level of side reaction below 5%. we will not need now to require from the simulation to go deeply to give me the exact result in the level of 0.1% impurities or side reactions because it is not relevant for me. For me, it is enough to have an order of magnitude of 1%, in order to decide about the operation conditions, equipment design or transfer technology activities.

With this approach, we will able to reduce dramatically the required time to solve by numerical method to non linear differential equations. If we are using simulation software that integrates process knowledge phenomenon with simplified numerical methods solutions of differential equations, this integration will provide relevant and representative solutions in short time… In VisiMix, we are connecting between process and equipment to provide fast results that are relevant, representative and provide a connection between real live conditions with under the process is progressing. Parameters like solid distribution, bubble size, Gas hold up, drop size distribution, mass and heat transfer coefficient and mores are typical parameters that could be calculated with VisiMix immediately and provide a representative characterization of the influence of the mixing in the process. We analyze this number to understand what happened in the process, so the origin of the solution is coming from the professional and understanding of the phenomenon.

We want to understand the phenomenon of mixing and we have enough data to characterize this phenomenon. We use this data with the solution of the numerical method in a way that will simplify this differential equation to be relevant for us and provide the number that will be representative, relevant, and reproducible even for you process parameters, because the goal is a process and, of course, not a calculation. Hence, this is the best way to simplify and understand the phenomenon, and then allocate numbers that will provide an understanding about the sensitivity and different kinds of phenomena that occur during the process.
