Closed Loop Corrosion Control: Case Studies Of A Reliable, Robust, & Sustainable Treatment Program

Picture for Closed Loop Corrosion Control: Case Studies Of A Reliable, Robust, & Sustainable Treatment Program
Available for download

An emerging market driver in industrial water treatment is the move to more sustainable chemistries. Corporate sustainability goals are becoming more common and more stringent. Customers are turning to water treatment companies for innovative solutions that can satisfy their sustainability goals and not sacrifice performance or asset integrity. Indeed, a major trend in evaporative open cooling water treatment is to move away from heavy metals such as zinc and other environmentally questionable materials such as phosphates. Another area of cooling water that is in need of a sustainability refresh is closed cooling loops. The most widespread closed cooling treatment programs are based on combinations of nitrite, molybdate, and borate. All three of these chemicals have regulatory, discharge and/or SH&E concerns.

Closed cooling loops are used to provide the required cooling to critical industrial equipment and processes that cannot tolerate the variability from open recirculating cooling towers. The key challenges in operating a closed loop are corrosion control and microbiological growth. A new non-toxic closed loop corrosion inhibitor program was developed that does not contain nitrite, heavy metal, P, B, or filming amine. This paper will present results from recent field trials using this new digitally-enabled, sustainable corrosion inhibitor program. The first field trial was conducted at a refinery in the Middle East that provided an opportunity to evaluate the new program in a hot loop (>90 °C) that experienced upsets and hydrocarbon ingress. A second field trial was conducted at a steel mill in Europe with a significantly more challenging makeup water that included moderate chloride and no hardness. Positive results from both field trials will be presented that will include coupon weight loss measurements, dissolved Fe concentration, and product actives monitoring.

UNS S209101, also known as XM-19 by ASTM A2762, is a nitrogen-strengthened austenitic stainless steel with high strength and excellent corrosion resistance. Besides nitrogen (N) it also contains higher amounts of chromium (Cr), nickel (Ni), manganese (Mn), and a similar molybdenum (Mo) content compared with UNS S31603, as well as small additions of niobium (Nb) and vanadium (V). High contents of Cr, Mo and N confer this stainless steel high localized corrosion resistance. Mo, Mn and Cr increase the nitrogen solubility in iron alloys.

Corrosion in Mooring systems for permanently moored floating production units has been identified as a problem area by authorities as well as industry. A Joint Industry Project (JIP) initiated by the Bureau of Safety and Environmental Enforcement (BSEE) with participation from major global oil and gas operators as well as equipment suppliers was established in 2014 to review the problem area. 1 Studies performed as a part of this program have shown that especially mooring chains located in tropical waters have shown signs of rapid corrosion, both general and localized with corrosion rates significantly larger than those specified in design standards. Increased corrosion allowance, as well as increased inspection requirements, have been recommended and corrosion has been reported as the leading cause for pre-emptive replacement of mooring.
