In chemical engineering and related fields, a unit operation is a basic step in a process. Unit operations involve a physical change or chemical transformation such as separation, crystallization, evaporation, filtration, polymerization, isomerization, and other reactions. For example, in milk processing, the following unit operations are ...
In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components.
A unit operation is a physical step in an individual chemical engineering process. Unit operations (such as crystallization , filtration , drying and evaporation ) are used to prepare reactants, purifying and separating its products, recycling unspent reactants, and controlling energy transfer in reactors.

Category. v. t. e. This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management ...
A process flow diagram ( PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...
Process engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. [ 1] By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as ...
v. t. e. In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. [ 1] Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort. In an "engineering" sense, a chemical process is a method intended to be used ...
A chemical process is a series of unit operations used to produce a material in large quantities. In the chemical industry, chemical engineers will use the following to define or illustrate a process: Process flow diagram (PFD) Piping and instrumentation diagram (P&ID) Simplified process description; Detailed process description; Project management
