The flash drum is a vapour liquid separator

The flash drum is a vapour liquid separator, its role is to split the mixture of the vapour-liquid mixture fed from the reactor. The vapour stream is released from the top of the drum and the liquid stream leaves from the bottom of the drum containing the Rhodium catalyst which is then recycled back to the reactor to be reused to aid reactions within the reactor. The design was to specify the flash separator operating conditions and physical attributes (addition of diameter and vessel length) that directly affect the cost of equipment and operating costs. The orientation of the vessel will be vertical as its ideal for high flow rates, the vertical separator the process, is more economical compared to the horizontal.
