Context & Assumptions

Column diameter sizing is a fundamental process engineering task that balances vapor throughput against the risk of flooding and entrainment. By ensuring the superficial velocity remains within design limits, engineers can optimize both the capital cost and the separation efficiency of the contacting device.
