    Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products .

  3. Hydrotreated vegetable oil - Wikipedia

    en.wikipedia.org/wiki/Hydrotreated_vegetable_oil

    Both HVO diesel (green diesel) and biodiesel are made from the same vegetable oil feedstock. However the processing technologies and chemical makeup of the two fuels differ. The chemical reaction commonly used to produce biodiesel is known as transesterification. [2] The production of biodiesel also makes glycerol, but the production of HVO ...

  4. 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.
