Version 4 of the Bell & Gossett System Syzer® program for PC computers is available. It is an update of a tool for calculating flow rates and pressure drops in HVAC piping systems. The program ...

Precisely formulated gas mixtures with known concentrations of particular target gases are referred to as calibration gas standards. To guarantee the accuracy of gas concentration measurements, almost ...

A method has been developed that allows direct, accurate calculation of recovery efficiency for Claus sulfur-recovery units (SRU). The calculation combines feed-gas data and tail-gas composition to ...
