Closer Look at Flammability, Inerting of Complex Hydrocarbon Mixtures

By Tarig Hussein and Daniel Maxa, University of Chemistry and Technology in Prague, and Martin Stukbauer, CEPS In the lifetime of oil and gas pipelines there are numerous events that could pose the potential of an explosion hazard, with commissioning, maintenance, replacement, as well as decommissioning and abandonment serving as common examples. In case of air purging, flammable mixtures are created in pipelines in an uncontrolled manner. The first part of this article is dedicated to a revision of basic flammability and inerting principles. Based on this background, applications of mobile nitrogen unit technology are described in the second part. The technology has been proven to increas
