Enviro-Solve® ProM® Non-Amine Mercaptan Scavenger

Q2 Technologies has brought to market the Enviro-Solve® ProM® series; an innovative non-amine/non-glyoxal mercaptans scavenger for crude oil applications.

Mercaptan Scavenger

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

A need was identified to reduce fouling created by amine based scavengers in refineries, production streams and crude oil terminals.

Mercaptans removal is necessary in feedstocks and refined products. Enviro-Solve® ProM® has consistently outperformed alternative chemistries


  • 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.
