Chemical engineers design things to ensure the most efficient work. This means that the entire producing chain should be planned and controlled for costs. A chemical guy can both simplify and complicate showcase reactions for an economic benefit. Utilizing a higher pressure or temperature makes several reactions simpler; ammonia, for example, is easily produced from the component elements in a high-pressure reactor. On the other hand, reactions with a small can be recycled endlessly, which would be complex, hard work if done manually in the laboratory. It is not unusual to build 6-step or even 12-step evaporators to reuse the vaporizing energy for an economic advantage. In contrast, laboratory chemists evaporate things in a single step.
