Back to Basics

The Essentials of Reverse Osmosis

Reverse osmosis (RO) is used throughout the chemical process industries (CPI). Review the basics to understand best practices for troubleshooting, monitoring, and cleaning.

Fluids and Solids Handling

Understand the Risks of Composite Intermediate Bulk Containers

Although composite intermediate bulk containers (CIBCs) provide ease of storage and transport, they pose a unique fire hazard that is often overlooked.

Computational Methods

Optimize Plant Water Use from Your Desk

Water pinch analysis and mathematical programming can be carried out using only a spreadsheet to determine the optimal water system for your plant. Examples, including a shale gas to ethylene process, illustrate the concept.
