Chemical processes use process streams to transport material from one point to another. Consider a stream with a mass flowrate m& (note that we could equivalently have used molar units). The material in the stream carries its kinetic, potential, and internal energy .

Department of Energy and Process Engineering Sept 2013 2 Absorption - definition • Absorption, in chemical technology, is a process in which atoms or molecules transfer from a gas phase into a liquid phase. The difference between absorption and adsorption is that .
chemical process typically took a team of chemical engineers using slide rules and adding machines days or weeks, if not months. And given the complexity of the problem, errors were common. The methods used in those days to solve material balance problems days are best described as ad hoc.

Process industries, businesses, homes, and transportation systems have vast heat requirements that are also satisfied by combustion reactions. The subject matter of this chapter therefore has wide applicability to a variety of heating processes. Combustion is the conversion of a substance called a fuel into chemical compounds
calculation, one typically has to make balances on individual process units, combinations of several units, as well as the overall, multiple unit system in order to arrive at the solution. Balances that are taken on the overall system, which do not involve any internal process streams, are referred to as overall balances. For each subsystem (e ...
For physical process, since there is no chemical reaction, the generation and consumption terms will become zero, and the balance equation for steady-state physical process will be simply reduced to: Input = Output 4.3. Balances on Single and Multiple Physical Systems 4.3.1. Procedure for Material Balance Calculations
Valve Selection Process General procedure for valve selection. 1. Identify design information including pressure and temperature, valve function, material, etc. 2. Identify potentially appropriate valve types and components based on application and function (i.e., block, throttle, or reverse flow prevention).
a reactor for a chemical process. One design may have low reactor cost, but the final materials leaving the unit need higher treatment cost while separating and purifying the desired product. Therefore, the economics of the overall process also play a vital role to select a suitable alternative design. Each chemical process consists of series of
portant chemical, biological, physical, safety, and mathe-matical data and concepts that are fundamental to the practice of the chemical engineering profession. With these principles you should be able to solve many chemical engineering problems. Good Luck! AIChE would like to .

Chemical reactors are vessels designed to contain chemical reactions2. It is the site of conversion of raw materials into products and is also called the heart of a chemical process. The design of a chemical reactor where bulk drugs would be synthesized on a commercial scale would depend on multiple aspects of chemical engineering.

of chemical processes. They describe an existing process or a hypothetical process in sufficient detail to convey the essential features. • A process flowsheet is a collection of icons to represent process and arcs to represent the flow of material to and from the units. It emphasizes the flow of material and energy in a chemical process.
In chemical reactors, we normally assume the internal energyis the dominant contribution and neglect the kinetic and potential energies. Normally we neglect the work done by the stirrer, unless the mixture is highly viscous and the stirring operation draws significant power [3]. Neglecting kinetic and potential energies and shaft work yields ...
