  2. McCabe–Thiele method - Wikipedia

    en.wikipedia.org/wiki/McCabe–Thiele_method

    For example, if the feed is a saturated liquid, q = 1 and the slope of the q-line is infinite (drawn as a vertical line). As another example, if the feed is saturated vapor, q = 0 and the slope of the q-line is 0 (a horizontal line). [2] The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed.

  3. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  4. Azeotropic distillation - Wikipedia

    en.wikipedia.org/wiki/Azeotropic_distillation

    Phase diagram (left) and process flow diagram (right) of an apparatus for the azeotropic distillation with "material separation agent". In this case the phase diagram includes a zone where components are not miscible, so following the condensation of the azeotrope, it is possible to separate the liquid components through decantation.

  5. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    Schematic flow diagram of a fluid catalytic cracker. The catalytic cracking process involves the presence of solid acid catalysts, usually silica-alumina and zeolites. The catalysts promote the formation of carbocations, which undergo processes of rearrangement and scission of C-C bonds. Relative to thermal cracking, cat cracking proceeds at ...

  6. Chemical process - Wikipedia

    en.wikipedia.org/wiki/Chemical_process

    More than one chemical plant may use the same chemical process, each plant perhaps at differently scaled capacities. Chemical processes like distillation and crystallization go back to alchemy in Alexandria, Egypt. Such chemical processes can be illustrated generally as block flow diagrams or in more detail as process flow diagrams. Block flow ...

    As a result, he did not contribute new material to further editions, which was done by others. The 5th edition (1995) was edited by Peter G. Urben and as the book was larger, was split into two volumes. Leslie Bretherick died in April 2003 [9] The 6th edition (1999), the 7th edition (2007) and the 8th edition (2017) were also edited by Urben.

    This started the practice of written instructions to provide standard, uniform results. The use of written procedures has evolved, giving the ability for design engineers and manufacturers to get the high standard results from any properly trained and certified liquid penetrant testing technician.

  9. Unit Operations of Chemical Engineering - Wikipedia

    en.wikipedia.org/wiki/Unit_Operations_of...

    The book starts with an introductory chapter devoted to definitions and principles. It then follows with 28 additional chapters, each covering a principal chemical engineering unit operation. The 28 chapters are grouped into four major sections: Fluid mechanics; Heat transfer; Mass transfer and equilibrium stages; Operations involving ...
