Prediction of Supersaturation in Reactive Absorption Columns

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

Prediction of Mean Drop Size in Pulsed Packed Extraction Columns

Conceptual Design of Reactive Distillation Columns with Non-Reactive Sections

Reactive distillation has received intense attention due to the well known benefits of integrating distillation with reaction in a single unit. While there are procedures available for the synthesis of non-reactive columns and of reaction-separation systems, the design of reactive distillation columns is still a challenge. This work presents a new synthesis and design methodology for reactive d...

Acoustic Detection of Flooding in Absorption Columns and Trickle Beds

In countercurrent flow absorption columns and trickle beds, if either the liquid or gas flow is too high the column becomes flooded with the liquid. Flooding is accompanied by a dramatic increase in pressure, resulting in inefficient operation and potential damage to equipment. To optimize efficiency, however, it is desirable to operate as close to flooding as possible. This article discusses t...
