The chemical engineering field is constantly changing, and so are available calculation tools and software packages. In short everyday life, it is a considerable challenge for a chemical engineer to know which tool can serve best for solving a particular problem. Nevertheless, the different packages can solve typical issues in mass and energy balance, fluid mechanics, heat and mass transfer, unit operations, reactor engineering, and process and equipment design and control.




 This article highlights essential tools and packages with their capabilities:                  

 

MS Excel

 

Microsoft Office Excel is a spreadsheet application that includes calculations, graphics tools, tables, and a macro programming language - Visual Basic. The main advantage of Excel is that it is available and used in industry and academia. Thus, it is a perfect tool or interfaces to perform calculations and connect different software so that the end user can interact with Excel. Behind the scenes, other software, such as CHEMCAD, MATLAB, etc., is running and reporting the results back to Excel.

 



 Why MS-Excel

·        Built-in functions and formulas – A large number of built-in functions are defined, such as statistical (MEAN, AVERAGE, t-test), algebraic (SUM, ROUND, LOG, LOG10), logical (IF, FALSE, etc.), references, database, and information. These are easily used in different types of formulas.

  • Column and row operations – It is easy to find and sort data and use it in replicated formulas etc.
  • Solver is the tool used within Excel to solve a set of equations and problem optimisation, including data collection to a given linear and nonlinear equation numerically. Solver is an add-in that requires activation.
  • Building functions in Visual Basic for Applications - Excel has built-in capability to generate customised parts using Visual Basic for Applications (VBA). This powerful tool can save time for you without becoming an expert in programming as it opens the possibility to run loops and conditionals in the background. This capability also allows the user to build relatively large equations in several areas of the worksheet (e.g., polynomials for estimating specific components' heat). Finally, it enables the user to read the calculations easily when looking at the formulas in the cells.

 

Excel has become a standard package, so several other specialised software use it as a source of information to report data since it is more user-friendly. So we can use the information in Excel to load it into MATLAB, HYSYS or CHEMCAD or send it back to Excel.

                                            

                                                           MATLAB

 

MATLAB: What is it?

Matlab is a software package that analyses and solves mathematical and engineering problems, including numerical computation, advanced graphics, visualisation, and a high-level programming language. It was developed by the mathematical computing software industry Mathworks in 1984. MATLAB treats all variables as matrices. The Matrix-based MATLAB language is the world's natural way to express computational mathematics.

Features of Matlab:

Matlab toolboxes are used for a variety of applications in various domains:

1. Statistics and Machine Learning: Handy for programmers, algorithms can also be used for big data applications.

2. Curve fitting: Helps to analyse the pattern of occurrence of data after a particular future trend. One can also do Integration, derivation, and interpolation.

3. Electric Vehicle Designing: Modelling and Designing of Electric Vehicle are done, and speed comparison of a motor can also be made using these tools.

4. Deep learning: These tools can also be used in applications like speech recognition, financial fraud reduction, and medical image analysis.

5. Image processing: Barcode Scanner, Image Enhancement, and digital Image processing applications can be made using this tool.

6. Financial Analysis: Elements such as profitability, solvency, liquidity, and stability can be identified and can evaluate business and cost of capital.

7. Signal Processing: Transforms such as Laplace, Fourier and Z-transform can be done on any signal, and any theorems can be evaluated.

 

Why use Matlab?

In chemical engineering, one can obtain the solution to every unsteady problem from differential equations with appropriate boundary conditions. Heat, mass, and momentum balance are in a differential equation. MATLAB can be used as a tool for solving differential equations. It is used in designing industrial equipment and structure with 3-dimensional visuals. It is used to generate various graphs in 2d and 3d. In any chemical industry, modelling and simulation play a significant role in designing any process or equipment. MATLAB is useful, from designing the reactor to modelling a method for reaching its desired output. MATLAB can do different types of modelling and simulations. Modelling means representing your system or process in a mathematical format. Simulation means executing your model for an assumed operating condition starting from initial values repeatedly until you achieve your desired output value. You can find the appropriate functional state for your desired output through this.

 Computational Fluid Dynamics (CFD)

 

Computational fluid dynamics (CFD) is the computer simulation of fluid flow behaviour in and around complex geometries, usually involving heat and mass transfer reaction phenomena. The simulation predicts flow fields and stress profiles in the region of interest, which is very useful in designing and optimising processes and equipment.

Basic subjects for CFD Modelling: Mathematics, Physics of flows, computer Science, and Experimental data for evaluation.

In general, CFD analysis involves three main phases:

·   Pre-processing 

·   Solving

·   Post-processing

 

Why use CFD?

An increase in the complexity of the product; there is also an increase in the number of physics, which means that you need to consider some additional physics that requires other analyses than just structural modelling. One that is growing in importance is CFD or Computational Fluid Dynamics.

"Computational fluid dynamics is the rapidly developing science of numerically solving the equations of fluid motion to make quantitative predictions and analyses of fluid flow phenomena. When appropriately used, CFD is often ideal for parametric studies or flow physics investigations that would otherwise be impractical or impossible through purely theoretical or experimental efforts. In addition, it can help you avoid some of the most common problems during product development that lead to failure.

 

Advantages of CFD analysis

·         The cost of analysis is low compared to experiments.

·         Provide detailed information.

·         CFD analysis requires less time to obtain results than experimental for most complex cases. Therefore, wind tunnels are getting replaced by CFD simulations in many universities and industries.

·         CFD analysis is an effective method for design optimisation in many automotive, aerospace and chemical industries.

·         Conducting a wind tunnel test is expensive and requires much time for the experimental setup.

·         We cannot fix probes or sensors to measure velocity and pressure at all locations for experimental measurements.

Various software is available in the market for chemical engineers in Academia and commercial purposes. The prominent segregation of software is based on subject & application, i.e., Process simulator, flow simulator, Mathematical Simulation tool, CAD, plant & Equipment design, etc. One should first look to the area of interest and firm hold on the subject and accordingly choose the software they want to proceed with. Software is like a black box one can get maximum output of the software only when one has a good hold on Subject fundamentals.
