Tower pressure relief calculation

A practical, less-complicated method for different emergency cases

Rahimi Mofrad, S., Petrofac Engineering & Constructions

In the hydrocarbon processing industries and chemical plants, fractionation towers are some of the most complicated equipment from a relief load study point of view. This is due to the variety of tower design parameters and operating conditions. The process designer is responsible for recognizing the different causes of over-pressurization and evaluating the relief load considering all possible operating parameters such as different feed compositions, capacities and product specifications, as well as start/end of run or summer/winter operation. Failure to recognize these effects is likely to expose the column to danger of overpressure and the possibility of catastrophic failure. A conservati
