Why is a pressure relief valve used in a bioreactor?

Answer and explanation

Correct answer: For safety from excess pressure

A pressure relief valve is a safety device used in the pressure-control system of a bioreactor. During operation, microbial metabolism may generate gases, heating can expand gases, and a blocked outlet or control failure can cause internal pressure to rise. If pressure exceeds the vessel’s safe design limit, the reactor may be damaged, rupture, or release material dangerously. A relief valve opens or otherwise relieves pressure at a predetermined safe level, thereby protecting the equipment, product and operators. Therefore option C is correct. Product colouring, giving a medium a name and counting microorganisms are unrelated activities; none is performed by a pressure relief valve.
