SUEZ announces new formula

Sour gas in oil and gas production streams can increase production costs, impact employees’ safety, endanger asset integrity and adversely impact the surrounding environment. To help oil and gas producers scavenge sour gas effectively, SUEZ has formulated a new version of its ProSolv HS line to effectively scavenge H2S without phase separation upsets that affect water quality or salt in condensate.

ProSolv HS is a non-nitrogen-based chemistry that does not impact downstream refining processes. It is safer to deploy compared to nitrogen-containing scavengers. It is injected with similar dose rates to the amine-based chemistries, which allows the use of existing infrastructure and pumping capabilities.

“Our new ProSolv HS is formulated specifically to address sour gas production conditions. The product can scavenge H2S levels to customer target KPIs without impacting process PH. This means no costly scale buildup occurs,” said Amy Ericson, Global Leader, Chemical and Monitoring Solutions - SUEZ’s Water Technologies & Solutions. It is a game changer for our customers that now can effectively utilise produced water without further treatment and are able to sell gas condensates with the correct salt level and sales specifications.”

Sour gas is natural gas that contains significant amounts of acidic gases such as H2S and carbon dioxide. Increased H2S levels in process streams prevent operators from processing and selling these streams in a cost-effective manner. ProSolv HS series includes a non-amine-based chemistry that scavenges H2S from process stream without creating any side effects to the downstream process. The new technology offers a range of solutions with cleaner processes and without precipitation to ensure a smooth separation with no process upsets.

Nitrogen-containing scavengers (such as Triazines) produce scale deposition resulting in pipeline pressure buildup that causes safety concerns, shut downs, deferred production and expensive unplanned maintenance to clean the scale buildup.
