Chemical Engineering Thermodynamics
Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. The backbone of this subject is the four "fundamental equations of Gibbs" that can be applied to derive thermodynamic properties using relatively simple math.
Chemical Process Calculations
Chemical engineers perform chemical process calculations in order to generate the desired materials. The only way to ensure ideal conditions of production is to perform the relevant chemical process calculations so as to determine various process parameters such as the flow velocity, concentration, and the temperature of the materials in the flow.
Mass transfer
Mass transfer is one of the quintessential chemical engineering subjects, and deals with the net movement of mass from one location, usually meaning stream, phase, fraction or component, to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation.
Process Design and Economics
In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials with optimal economy. The design and economic considerations start at a conceptual level and ultimately end in the form of concrete construction and economic plans.
Process dynamics and control
A process is a dynamical system whose behavior changes over time, and hence control systems are needed to handle such changes in the process. Thus, it is important to understand the process dynamics when a control system is designed.
Reaction Engineering
Chemical reaction engineering is a specialty in chemical engineering or industrial chemistry dealing with chemical reactors. In the most generic sense, the term relates specifically to catalytic reaction systems where either a homogeneous or heterogeneous catalyst is present in the reactor.
Transport Phenomena
The study of transport phenomena concerns the exchange of mass, energy, charge, momentum and angular momentum between observed and studied systems. Mass, momentum, and heat transport all share a very similar mathematical framework, and the parallels between them are exploited in the study of transport phenomena in various disciplines, including chemical engineering.
