Special Section: Process Intensification

Process Intensification in Practice

RAPID’s Quest for Intensification

These and other RAPID-funded ventures could transform industry by making chemical processes cleaner, smaller, safer, and more energy-efficient.

Introduction to Dividing-Wall Columns

A dividing wall can be added within a distillation column to improve the separation efficiency of three or more products.

A Building-Block Approach to Process Intensification

This new approach represents chemical processes as abstract blocks arranged in a two-dimensional grid. Mathematical-programming-based optimization can identify the best design for intensification at the equipment and flowsheet levels.

Using Simulation and Digitalization for Modular Process Intensification

These tools enable engineers to create a digital twin of a process, which can be key to developing new technologies and testing them virtually at a rapid pace.

Reactions and Separations

Evaluate Catalyst Replacement Economics: Part 2 — Continuous Replacement

Reaction conversion and selectivity can deteriorate as a catalyst ages. Optimize continuous catalyst makeup and replacement rate to improve profitability.

Back to Basics

Risk-Based Process Safety

What happens when organizations don’t follow risk-based process safety guidelines?
