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. Process design can be the design of new ...
In 1986, he joined the Department of Chemical Engineering at Texas A&M University. Dr. Holtzapple's research interests include the following: fuels and chemicals from biomass, food and feed processing, water desalination, high-efficiency air conditioning, high-efficiency engines, jet ejectors, compressors, expanders, conversion of waste heat to ...
Cedar Bayou plant is a petrochemical manufacturing facility located in Baytown, Texas. It is the largest U.S. manufacturing facility of Chevron Phillips Chemical Company. [ 1] The plant operates seven process units on approximately 1,400 acres producing Ethylene, Propylene, Normal Alpha Olefins (NAO), High Density Polyethylene (HDPE), Low ...
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.

In industrial process engineering, mixingis a unit operationthat involves manipulation of a heterogeneousphysical system with the intent to make it more homogeneous. Familiar examples include pumpingof the water in a swimming pool to homogenize the water temperature, and the stirring of pancakebatter to eliminate lumps (deagglomeration).
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 ...
