With the simplifying assumption that all of the noncondensable gases exit via the vapor stream, material balances and equilibrium calculations can be used to determine the compositions of the emissions streams leaving a control device.

A sound theoretical model of the process to be scaled is the best approach; if one is not available, bench-scale testing, physical scale modeling or full-scale modeling is required. Here are guidelines as to which method is appropriate for various...

Twentieth-century engineering enabled life as we know it. The National Academy of Engineering looks at what is needed in the future.

Chemical Engineers At NASA Take It To The Next Level

Options abound, but operators need to balance performance and safety considerations.

This article introduces a novel approach to solving flow and pipe-sizing problems based on two new dimensionless quantities that are independent of line size and flow.

Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.

Whatever problems may be caused by climate change, engineers will be expected to solve them.Now is the time to begin addressing the issues at the local and regional scale.

Use this approach for the initial evaluation of potential reactivity hazards in storage applications.
