Mercaptan Scavenger

Q2 Technologies and its former partner Quaker Chemical developed the triazine technology that is used world-wide today.

Mercaptans are a common contaminant in many hydrocarbon streams, including crude oil and refined products. Mercaptans or thiols are organosulfur compounds that cause odor issues, can increase corrosivity, contribute to instability, and make it difficult to meet product specifications. The presence of mercaptans along the oil production chain can create problems both from stainless steel and alloys corrosion during storage and transportation, and from odor complaints from neighbors.

Mercaptan removal is necessary in feedstocks and refined products. Enviro-Solve® ProM® has consistently outperformed alternative chemistries for lower chain mercaptan removal. Our mercaptan scavenger is currently being used in multiple applications. Whether you need mercaptan removal from natural gas, mercaptan removal from LPG, or from any other hydrocarbon, contact your Q2 Technologies advisor to find solutions to mercaptan contamination. We have the mercaptan scavengers to satisfy your needs.


  • Hundreds of barges and tankers succesfully treated

  • Treating 7-10% of monthly Eagle Ford production

  • Helping American producers become leading exporters worldwide

We have treated billions of dollars worth of crude oil using Enviro-Solve® chemistries including Pro3® and ProM®.

ProM® Lab Data:

An experiment was designed using Trace Sulphur Analysis to determine the performance of ProM® on different mercaptans from condensate sample from Alberta, CA. A baseline was obtained and then ProM® was added to the Test Condensate. The ProM® was injected into the Test Condensate sample and then agitated by hand for a period of five minutes.

The Trace Sulphur Analysis was then performed on the sample after 24 hours had elapsed.

The samples was then agitated for 2 minutes and allowed to sit for another 24 hours until 48 hours total test time had elapsed. The Trace Sulphur analysis was then repeated. The results are as follows.
