AUTOMATION AND CONTROL OF CHEMICAL AND PETROCHEMICAL PLANTS

pharmaceuticals, polymers, paints, and specialty chemicals are produced in batch processes. Cooking food on a stove or in an oven is a familiar example of a batch process. Chemical and petrochemicals that are manufactured in large quantities are produced in continuous processes.

Visual Encyclopedia of Chemical Engineering

Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This allows for extensive mixing in all directions. A result of the mixing is excellent temperature stability and increased mass-transfer and reaction rates. Fluidized bed reactors are capable of handling large amounts of feed and catalyst.

Flow vs. batch chemistry: how the reactor design affects the

With flow chemistry, accurate reactor geometry means that you can have multiple inputs which meet at the same junction and at the same time. This, alongside precisely defined dimensions across each channel, ultimately means there is less opportunity for variation downstream and increased batch to batch consistency. Fast-mixing

(62e) Comparison of Batch and Continuous Industrial Distillation | AIChE - AIChE | The Global Home of Chemical

Batch distillation is still widely used in chemical industry. Many smaller chemical plants operate in batch mode, with batch reactors and batch rectifiers. The main reason is production flexibility where different chemicals are being made in the same equipment in ...
