Chemical reactors are vessels that are designed for a chemical reaction to occur inside of them. The design of a chemical reactor deals with multiple aspects of chemical engineering. It is the job of the chemical engineer to ensure that the reaction proceeds with the highest efficiency towards the desired output product, producing the highest yield of product while requiring the least amount of money to purchase and operate. Normal operating expenses include energy input, energy removal, raw material costs, etc. Energy changes can com ...

These two steps lead to a basic description of the system and its boundaries, in chemical engineering called a reactor model. The three most simple reactor models are: Ideal (continuosly stirred) Batch reactor Ideal tank reactor, also named Continuously Stirred Tank Reactor (CSTR) Ideal Plug Flow Reactor (PFR) Mass balance - Ideal Batch reactor. A closed system. Many chemistry textbooks implicitly assumes that the studied system can be described as a batch reactor when they write about reaction kinetics and chem ...

Thermodynamics (from the Greek thermos meaning heat and dynamis meaning power) is a branch of physics that studies the effects of temperature, pressure, and volume changes on physical systems at the macroscopic scale. In simpler terms, heat means ‘energy in transit’ and dynamics relates to ‘movement’. Thus, in essence thermodynamics studies how energy instills movement. The starting point for most thermodynamic considerations are the laws of thermodynamics. These laws postulate that energy can be exchanged ...

Biochemical engineering is a branch of chemical engineering that mainly deals with the design and construction of unit processes that involve biological organisms or molecules. Biochemical engineering is often taught as a supplementary option to chemical engineering due to the similarities in both the background subject curriculum and problem-solving techniques used by both professions. Its applications are used in the pharmaceutical, biotechnology, and water treatment industries. Biochemical engineering - The Bioreactor ...

Vitriol is the name that alchemists gave to sulfuric acid. The name was also used for various sulfate salts, such as copper(II) sulfate (blue vitriol, or rarely Roman vitriol), zinc sulfate (white vitriol), iron(II) sulfate (green vitriol), iron(III) sulfate (vitriol of Mars), or cobalt(II) sulfate (red vitriol). Oil of vitriol is concentrated sulfuric acid so named due to its oily appearance. Vitriol is also a quality of abusive or malicious forms of speech or feelings. Vitriol - ExtractionIncluding:

Countercurrent exchange is a mechanism used to transfer some property of a fluid from one flowing current of fluid to another across a semipermeable barrier between them. The property transferred could be heat, concentration of a chemical substance, or others. Countercurrent exchange is used extensively in biological systems for a wide variety of purposes. For example, fish use it in their gills to transfer oxygen from the surrounding water into their blood, and birds use a countercurrent heat exchanger between blood vessels in their ...

A chemical reaction is a process that results in the interconversion of chemical substances [1]. The substance(s) initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change and it yields one or more product(s) which are different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bond ...

In physical chemistry, chemical kinetics or reaction kinetics study reaction rates in a chemical reaction. Analysing the influence of different reaction conditions on the reaction rate gives information about the reaction mechanism and the transition state of a chemical reaction. Peter Waage developed the law of mass action in 1864 that stated for the first time that the speed of a chemical reaction is proportional to the quantity of the reacting substances. Chemical kinetics - Rate of reaction. Kine ...

In chemical engineering and related fields, a unit operation is a basic step in a process. For example in milk processing, homogenization, pasteurization, chilling, and packaging are each unit operations which are connected to create the overall process. A process may have many unit operations to obtain the desired product. Historically, the different chemical industries were regarded as different industrial processes and with different principles. In 1923 William H. Walker, Warren K. Lewis and William H. McAdams wrote the book ...

The mass that enters a system must ( conservation of mass principle) either leave the system or accumulate within the system, i.e. IN = OUT + ACC where IN denotes what enters the system, OUT denotes what leaves the system and ACC denotes accumulation within the system (which may be negative or positive). Mass balances are often developed for total mass crossing the boundries of a system, but they can also focus on one element (e.g. carbon) or chemical compound (e.g. water). When mass balances are wr ...

In the various subfields of physics, there exist two common usages of the term flux, both with rigorous mathematical frameworks. In the fields of heat transport and mass transport (fluid dynamics, hydrogeology, chemical engineering), flux is defined as the amount of a given quantity that flows through a unit area per unit time (Bird, Stewart, and Lightfoot, Transport Phenomenon, 1960). Flux in this definition is a vector. In the field of electromagnetism, flux is usually the integral of a vector quantity o ...
