Discussion topics include sulfur pit/tank vent pit containment and scrubbing, proper air flow through sulfur pits, fresh acid storage tank vent containment, potential ingress air drying, and spent acid storage tank inert gas blanketing and venting. Vapor scrubbing, combustion and adsorbent options will also be explained.

EXPERT: Chris Brown

Hydrogen Mitigation

An electrochemical reaction occurs when sulfuric acid is in the presence of iron, resulting in the release of hydrogen. As strong acid systems are composed primarily of various steels, iron is a necessity for making sulfuric acid. Hydrogen generation and ignition in sulfuric acid plants may be a well-discussed topic, but it is advisable to keep it in front of experienced plant operators as well as fresh faces. This presentation will discuss how advances in process technology impact hydrogen generation and what steps can be taken to reduce hydrogen generation and prevent hydrogen ignition.
