    01/03/2015· A block flow diagram (BFD) is a drawing of a chemical processes used to simplify and understand the basic structure of a system. A BFD is the simplest form of the flow diagrams used in industry. Blocks in a BFD can represent anything from a single piece of equipment to an entire plant. For a complex process, block flow diagrams can be used to break up a complicated system into more

    CONTACT PROCESS Sulfuric acid is one of the most important

    Sulfuric acid has a very strong affinity for water: it absorbs water from mixtures such as moist air and forms an aqueous solution. Concentrated sulfuric acid will remove the waters of hydration in hydrated salts. Blue copper (II) sulfate crystals are turned to white anhydrous copper sulfate by the removal of water.

    What Is the Contact Process for Sulfuric Acid?

    The contact process for sulfuric acid could react sulfur trioxide directly with water, but this reaction is very unstable and difficult to control. Sulfuric acid is mixed with the trioxide molecule, which forms oleum or fuming sulfuric acid. Oleum is a very reactive acid containing excess sulfur molecules, but it can be mixed with water in a controlled way to form sulfuric acid while
