Micro process engineering. Micro process engineering is the science of conducting chemical or physical processes (unit operations) inside small volumina, typically inside channels with diameters of less than 1 mm (microchannels) or other structures with sub-millimeter dimensions.
These processes are usually carried out in continuous flow mode, as opposed to batch production, allowing a throughput high enough to make micro process engineering a tool for chemical production. Micro process engineering is therefore not to be confused with microchemistry, which deals with very small overall quantities of matter. The subfield of micro process engineering that deals with chemical reactions, carried out in microstructured reactors or "microreactors", is also known as microreaction technology. The unique advantages of microstructured reactors or microreactors are enhanced heat transfer due to the large surface area-to-volume ratio, and enhanced mass transfer.
Process Intensification[edit] History[edit] See also[edit] Particle technology. Particle technology is that branch of science and engineering dealing with the production, handling, modification, and use of a wide variety of particulate materials, both wet or dry, in sizes ranging from nanometers to centimeters; its scope spans a range of industries to include chemical, petrochemical, agricultural, food, pharmaceuticals, mineral processing, advanced materials, energy, and the environment.
This definition is given (essentially) by the Particle Technology Forum,[1] an international and interdisciplinary forum, but also a division of the American Institute of Chemical Engineers, and as such is included in their list under the title of AIChE’s Technical Divisions and Forums.

Oldest power station utilizing circular fluidized bed technology, in Lünen, Germany A fluidized bed is formed when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause the solid/fluid mixture to behave as a fluid.
This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and characteristics of normal fluids; such as the ability to free-flow under gravity, or to be pumped using fluid type technologies. The resulting phenomenon is called fluidization. Fluidized beds are used for several purposes, such as fluidized bed reactors (types of chemical reactors), fluid catalytic cracking, fluidized bed combustion, heat or mass transfer or interface modification, such as applying a coating onto solid items.
Properties of fluidized beds[edit] A fluidized bed consists of fluid-solid mixture that exhibits fluid-like properties. Packed bed. Super-Raschig rings Structured packing Applications[edit] Packed column[edit] Columns used in certain types of chromatography consisting of a tube filled with packing material can also be called packed columns and their structure has similarities to packed beds.
Column structure: random and stacked packed columns[edit] The column can be filled with random dumped packing (creating a random packed column) or with structured packing sections, which are arranged or stacked (creating a stacked packed column). Liquid and vapor distribution (vapor to liquid ratio)[edit] Another factor in performance, in addition to the packing shape and surface area, is the liquid and vapor distribution that enters the packed bed. Packed column vapor-equilibrium curve[edit] Packed columns have a continuous vapor-equilibrium curve, unlike conventional tray distillation in which every tray represents a separate point of vapor-liquid equilibrium.

Chemical Search Engine. Topic:Chemical engineering. Welcome to the Division of Chemical engineering!
Part of Engineering and Technology and the School of Engineering Related: School of Chemistry Chemical engineering is the branch of engineering that deals with the application of physical science (in particular chemistry and physics) and mathematics to the process of converting raw materials or chemicals into more useful or valuable forms. As well as producing useful materials, chemical engineering is also concerned with pioneering valuable new materials and techniques; an important form of research and development. Chemical engineering largely involves the design and maintenance of chemical processes for large-scale manufacture. Chemical engineers in this branch are usually employed under the title of process engineer. Active Participants[edit] Chemical Engineering.
