B-Chem: Non-Triazine H2S Chemical Scavenger and Water Vapor Scavenger

B-Chem –SGT-281

H2S scavenging is the process of removing H2S from natural gas streams in order to maintain pipeline integrity and safety.  Bold’s proprietary chemical, SGT-281, is a non-triazine based H2S scavenger.  Bold provides a full service solution using SGT-281 with Bold’s equipment, or SGT-281 can also be utilized with customer owned equipment.

How it Works

H2S rich gas enters a contact tower where it flows through a fluid bed of SGT-281. The bed is enriched with SGT-281 as needed. The treated gas stream exits the contact tower and flows into a spent solution scrubber where spent chemical is dropped out and the sweet gas exits the gas outlet. The non-hazardous spent SGT-281 is sent through a common or dedicated facility drain line.

B-Chem –Tri-ethylene Glycol

Tri-ethylene glycol is utilized to remove water vapor from natural gas streams.  Bold utilizes tri-ethylene glycol with its proprietary dehydration assets or our customer’s owned equipment to remove water vapor from natural gas streams for pipeline or gas lift dehydration applications.

How it Works

Tri-ethylene glycol is utilized in dehydration units within the absorber tower where it descends in counter currently to the gas flowing through the contactor absorbing the water vapor contained in the gas stream.
