Key Considerations in Safe and Efficient Gas Delivery

0

Supplying high-purity carrier, support, process, or calibration gases safely and cost efficiently, without compromising purity and sample integrity, is best accomplished with a gas sampling and control system having components compatible with the sample and conditions required for the specific application.

This article will focus on two key considerations in specifying such systems — pipeline size and materials compatibility.

PIPELINE SIZE 

Chemical process and quality control laboratory applications generally require delivering the process, calibration, or instrument support gas at specific pressures and flow rates in as unaltered a condition as possible. To do this, the diameter of the piping within the system must be sized appropriately. For any piping system under actual flow conditions, there will be a pressure drop in the system from the inlet, or starting point, to the furthest point. This pressure drop is dependent on the flow rate of the gas and the distance to the furthest point. In general a pressure drop of no more than 10 percent of the inlet pressure is acceptable.
