Reaction vessels are at the heart of a chemical plant. They are where the chemical changes and reactions take place. The capacity of reaction vessels can range from50 litres to 250,000 litres and they are generally made from stainless steel, glasslined steel, glass or ceramics.The ingredients for the chemical reaction are called the reactants. These rawmaterials can be loaded into the reaction vessel in a variety of ways. Measured amounts of reactants may be pumped into the vessel through pipes attached to inletvalves. Powders or liquids may be poured into reaction vessels using large funnels,called hoppers, connected to the top of the vessel.The conditions inside a reaction vessel are controlled to give the fastest possiblechemical reaction. This can include: Heating the vessel to speed up a chemical reaction. This is achieved by havingsteam-filled pipes inside the vessel or in a "jacket" surrounding it. Temperaturesof several hundred degrees centigrade may be required. Cooling the reaction vessel may be required if the chemical reaction producesheat. A cold water jacket cools the vessel and prevents the build up ofdangerously high pressures. Cooling water flows constantly through the jacketand removes heat from the reaction vessel. This water is passed through a heatexchanger, to cool it down, before being returned to continue the cooling of thereaction vessel. Stirring the contents of the reaction vessel mixes them thoroughly. This makessure that the reaction goes as quickly as possible and that all of the reactants are involved in the reaction. A variety of paddles can be used with speeds of rotationthat range from 30-40 revolutions, to several thousand revolutions per minute.The diagrams below show a variety of paddles used to stir reaction mixtures. Increasing the pressure inside the vessel. Some reactor vessels may be kept at ahigh pressure to improve the amount of product made or speed up the reaction.Sensors monitor these conditions and operators, or automatic systems, make the necessary adjustments to maintain the best conditions for the chemical reaction.
