H2S Scavenging for Asphalt Bitumen
With an increasing focus on refinery employee safety and community stewardship, high H2S levels in asphalt are a concern to refiners and terminal operators. Challenges such as high temperatures have limited the chemistry selection for effective chemical scavenging. The Nalco Water patented use of organometallic scavengers has allowed our partners to successfully manage H2S levels in asphalt applications over the past two decades.
