Emergency Mercaptan & H2S Treatment for Crude Oil at Port

We at Q2 Technologies® know how hectic it can be when a crude shipment is found to be out of specs. This calls for adequate treatment and time is of essence, given that the expense of loading crude into a ship will be delayed until the cargo meets the requirements. Regardless of the time of day or the day of the week, vessels are always on the move and ports charge for the time a ship is using a berth.

Emergency Call for Mercaptan Treatment

On Saturday morning at 10:00 am we got a call from a customer. The customer requested 7 truckloads of Pro3® to be delivered during Saturday and Sunday. 750,000 barrels of crude oil were to be loaded to an Aframax vessel at a Gulf terminal. The oil had higher levels of mercaptans than anticipated. We were able to coordinate our manufacturing and logistics teams to ensure timely manufacture and delivery of our non-amine/non-glyoxal mercaptans scavenger for crude oil applications Pro3®. Our dedicated fleet of trucks allowed us to respond quickly and finish the project in 36 hours.

Oil tanker at port, it is very important to minimize the loading time of the vessel.

Direct Injection and Successful Project Completion

Our first two Pro3® deliveries were one on Saturday and the remaining 5 on Sunday. Upon delivery, Pro3® was directly injected into a shore tank and allowed to mix. In about 36 hours from first notice, the project was successfully completed as the ship started being loaded late on Sunday night.  At Q2 Technologies, we help our clients remove mercaptans and get more for their barrel. Our 24/7 response capacity allows for on demand treatments while avoiding costly demurrage’s. Pro3® is used to treat crude to remove mercaptans and H2S while maintaining the crude oil’s quality.

Understanding Mercaptans and Crude Oil Quality

Mercaptans occur naturally in sour crude and its concentration varies as it commingles with crudes from different sources. When a ship comes to port, the crude owner needs to certify that the oil being delivered meets the specs defined in the sale agreement. The presence of H2S and/or mercaptans often lowers the value of the crude and shipments may be rejected if the sales specification on the crude oil sale contract is no met.  Contact us today to find out how we can help you too.

When introduced into a stream afflicted with H2S, the hemiformal decomposes to release formaldehyde, which then reacts with hydrogen sulfide to form stable, non-volatile byproducts such as thiomethylene glycol.  The reaction is typically fast and efficient, particularly in aqueous or mixed-phase environments. Unlike some traditional scavengers, hemiformal can maintain activity across a broad pH range and is less likely to generate problematic solids. When considering if hemiformal is the right product, certain operating conditions are reviewed, such as pH and temperature.

Key Benefits:

  • Controlled formaldehyde release 
  • Lower vapor pressure and improved safety profile 
  • Broad applicability across liquid and gas-phase systems 
  • Reduced scaling in sour water stripping and other high-temp operations 
  • Hemiformal can make the scavenger safe for transport as it is a very stable compound 

Heading 5

Hemiformal is used in a variety of upstream and midstream applications, including: 

  • Gas sweetening systems 
  • Produced water treatment 
  • Crude oil storage and transport 
  • Sour water stripper overheads 
  • Temporary H2S mitigation during maintenance or turnaround

Its adaptability makes it especially useful in operations where system conditions fluctuate or where traditional triazine-based products may underperform. 

Heading 6

While hemiformal offers many advantages, it is not a one-size-fits-all solution. The rate of formaldehyde release can vary depending on formulation and environmental conditions. Additionally, while safer than raw formaldehyde, hemiformal must still be handled with care and appropriate PPE. 

For optimal results, formulation expertise and application-specific customization are key—something we at Q2 Technologies excel at delivering.
