Simplified Nomograph method

Fauske11 developed a simplified chart-driven approach to the two-phase reactor relief problem. He suggested the following equation for determining the relief area  [Pg.401]

GT is the mass flux through the relief, and Afv is the venting time. [Pg.402]

Equation 9-22 was developed by Boyle12 by defining the required vent area as the size that would empty the reactor before the pressure could rise above some allowable overpressure for a given vessel. [Pg.402]

The mass flux GT is given by Equation 9-15 or 9-18, and the venting time is given approximately by [Pg.402]

Equation 9-24 provides a conservative estimate of the required vent area. By considering the case of 20% absolute overpressure, assuming a typical liquid heat capacity of 2510 J/kg K for most organic materials, and assuming a saturated water relationship, we can obtain the following equation13  [Pg.402]


Although nomographs, simplified equations, and shortcut methods are included, every effort has been made to indicate the theoretical background and assumptions for these relationships. The true value of plant design and economics for the chemical engineer is not found merely in "the ability to put... [Pg.924]
