Chemical Engineering Tools

Chemical engineers combine the engineering and chemistry to aid in making products and other materials useful to society. Chemical engineers are responsible for activities like research and design, development and production. Chemical engineers work in manufacturing and industrial processes. They can be found working from laboratories to pilot plants. Chemical engineers use different tools and instruments in their evaluation and analysis.

Mass Balance
Mass entering the system will equal the mass coming out of the system.

Heat Balance
Energy entering the system + the resulting energy - energy out = energy transformed the energy accumulated balance
Mass or heat transfer rate from the two systems together. 

(balance of chemical reactions, equilibrium phase)

The Rate of Process
The rate of mass transfer (reaction rate / kinetics) and the rate of heat transfer.

Economy
Chemical processes in scale-up in the scale of the plant
Design Strategy and its economic feasibility.

Thermal Analyzers and Calorimeters

      Thermal analyzers and calorimeters are used to analyze the specific heat capacity of a certain substance. Specific heat capacity is described as how much heat a given substance can take when extreme temperature is applied. Calorimeters and thermal analyzers both have a heat source to apply a specific temperature or heat to the material. These instruments also contain devices for measuring temperature that can read the change in temperature on the sample substance. With the use of these devices, chemical engineers can study the properties of substances as they change in form or composition when they are subjected to a certain temperature. Chemical engineers need to know the specific heat capacity of substances like metals before approving their manufacturing or industrial use.

Density Test Equipment 

       Chemical engineers use density test equipment to analyze the density of substances. Density is defined as a measure of a mass of the substance per unit volume. The density test equipment has many specifications like sample volume, range of measurement and pressure. If the density of material does not meet the specified standards, the chemical engineer will not allow their use based on their findings. For example, materials with a higher density, such as steel, are needed for building and construction. Steel has a higher density than wood and is used for heavier applications.

Leak Testing Equipment  

      Leak testing equipment is used by chemical engineers to measure leakage or the escape of liquids and gases from sealed and air-tight containers or systems. Leak testing is especially important when handling toxic substances and chemicals. The containers of these sensitive substances must be free from the risk of leakage to avoid contamination. Leak testing equipment can also be used in manufacturing plants to test bottles, cans and plastic containers prone to leaking. Leak testing equipment also comes with other components like gauges and pumps. The object to be tested is subjected to leak testing methods like bubble testing to test substances like oil and gasoline. Chemical engineers ensure that the containers of these substances are free from leakage to keep users safe.
