Chemical reactors have always been considered as the heart of chemical processes. It is generally understood to be a process vessel used to carry out a chemical reaction. Improved reactor design and operation will usually translate into significant cost savings and revenue potentials for the chemical plants.
continuous stirred tank reactor
In a CSTR, one or more reactants, for example in solution or as a slurry, are introduced continuously into a reactor equipped with an impeller/stirrer and the products are removed continuously. The impeller stirs the reagents vigorously to ensure good mixing so that there is a uniform composition throughout. The composition at the outlet is the same as in the bulk in the reactor.
gas induced reactor
Gas-liquid contacting is an important unit operation in chemical and biochemical processes, but the gas utilization efficiency is low in conventional gas-liquid contactors especially for sparingly soluble gases.
The simplest type of reactor is a batch reactor. Materials are loaded into a batch reactor, and the reaction proceeds with time. A batch reactor does not reach a steady state, and control of temperature, pressure and volume is often necessary. Many batch reactors therefore have ports for sensors and material input and output.
