The following P\&ID diagram shows a distillation column that separates Benzene and Toluene from a mixture. Benzene is recovered at the top of the column and Toluene at the bottom. Some fuel gas is collected at the top. Determine the following: 1. Explain why some fluids are sent to flare but some are sent to atmosphere. 2. Five causes that may lead to an increase in the amount of fluid sent to flare. 3. Two causes that may lead to an increase in temperature in tower's lower section. 4. Two causes that may lead to a decrease in Toluene production rate. 5. Two causes of a sudden fall in temperature at all locations along the tower. 6. Two causes of an increase in reflux rate
