  1. Micro process engineering

    Micro process engineering is the science of conducting chemical or physical processes unit operation s 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 microreactor s , is also known as microreaction technology . The unique advantages of microstructured reactors or microreactor s are enhanced heat transfer due to the large surface area to volume ratio, and enhanced mass transfer . For example, the length scale of diffusion processes is comparable to that of microchannels or even shorter, and efficient mixing of reactant s can be achieved during very short times typically milliseconds . The good heat transfer properties allow a precise temperature control of reactions. For example, highly exothermic reaction s can be conducted almost ... or running reactions at more extreme parameters is known as process intensification . History Historically, micro process engineering originated around the 1980s, when mechanical micromachining methods .... Process Intensification While the dimensions of the individual channels are small, a micro process engineering device microstructured reactor can contain many thousands of such channels, and the overall size of a microstructured reactor can be on the scale of meters.

    Unreferenced date December 2009 In industrial process engineering , mixing is a unit operation that involves manipulating a heterogeneous physical system, with the intent to make it more wiktionary Homogeneous homogeneous . Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature , and the stirring of pancake batter to eliminate lumps. File Agitator.gif thumb 300px right agitating vessel Solids mixing Blending powders is one of the oldest unit operations in the solids handling industries. For many decades powder blending has been used just to homogenise bulk materials. Many different machines have been designed to be able to handle materials with various bulk solids properties. On the basis of the practical experience gained with these different machines, engineering knowledge has been developed to construct reliable equipment and to predict scale up and mixing behaviour. Nowadays the same mixing technologies are used for many more applications to improve product quality, to coat particles, to fuse materials, to wet, to dispers in liquid, to agglomerate, to alter functional material properties, etc. This wide range of applications of mixing ....

  1. Process capability

    A Process engineering process is a unique combination of tools, materials, methods, and people engaged ... s, or product Tolerance engineering tolerance s. Engineering can conduct a process capability ... measurable output so that engineering is confident that the process is stable and so that the process ... version CMMI continuous also follows this approach. See also Process engineering Capability Maturity ... distribution Six Sigma Statistical interference Statistical process control Tolerance engineering References Pyzdek, T, Quality Engineering Handbook , 2003, ISBN 0824746147 Bothe, D. R., Measuring Process ... have inherent statistical variability which can be evaluated by statistical methods. The Process Capability is a measurable property of a process to the specification, expressed as a process capability index e.g., C SUB pk SUB or C SUB pm SUB or as a process performance index e.g., P SUB pk SUB or P ... that predict how many parts will be produced out of specification OOS . Process capability is also defined as the capability of a process to meet its purpose as managed by an organization s management and process definition structures ISO 15504 . Two parts of process capability are 1 Measure the variability of the output of a process, and 2 Compare that variability with a proposed specification or product tolerance. Measure the process The input of a process usually has at least one or more measurable ... the output data shows a normal distribution the process can be described by the process mean average and the standard deviation . A process needs to be established with appropriate process control s in place. A control chart analysis is used to determine whether the process is in statistical control . If the process is not in statistical control then capability has no meaning. Therefore the process ... needs to be obtained from the measured output of the process. The more data that is included the more ... include the normal variety of production conditions, materials, and people in the process. With a manufactured ...   more details



  1. Unified Process

    and implementation process Rational Unified Process System Engineering RUP SE , a version of RUP ... . Adopting the Rational Unified Process Success with the RUP . ISBN 0 321 20294 5. Software engineering ...The Unified Software Development Process or Unified Process is a popular iterative and incremental development iterative and incremental software development process framework. The best known and extensively documented refinement of the Unified Process is the IBM Rational Unified Process Rational Unified Process RUP . Image UnifiedProcessProjectProfile20060708.png frame right Profile of a typical project showing the relative sizes of the four phases of the Unified Process. Overview The Unified Process is not simply a process, but rather an extensible framework which should be customized for specific organizations or projects. The Rational Unified Process is, similarly, a customizable framework. As a result it is often impossible to say whether a refinement of the process was derived from UP or from RUP, and so the names tend to be used interchangeably. The name Unified Process as opposed to Rational Unified Process is generally used to describe the generic process, including those elements which are common to most refinements. The Unified Process name is also used to avoid potential issues of trademark infringement since Rational Unified Process and RUP are trademarks of IBM . The first book to describe the process was titled The Unified Software Development Process ISBN 0 201 57169 ... unaffiliated with Rational Software have published books and articles using the name Unified Process , whereas authors affiliated with Rational Software have favored the name Rational Unified Process . Unified Process Characteristics Iterative and Incremental Image Development iterative.gif frame ... of the project Software development process The Unified Process is an iterative and incremental development process.
