The utilization of volatile corrosion inhibitors (VCI) in dry packaging scenarios have become ubiquitous throughout industry for the protection of metal parts during shipping and storage. Initial protective packaging applications of VCIs involved coated paper which was used to wrap or interleave metal parts for transportation and/or storage. This type of wrapping evolved into film packaging where the inhibitors were extruded into film.

The application of corrosion inhibitors are fundamental to the safe and reliable operation of carbon steel infrastructure, presenting one of the most cost effective methods of internal pipeline corrosion control when deployed correctly. Despite decades of application in the oil and gas industry, a number of gaps remain in relation to our fundamental understanding of the performance of inhibitors. This is particularly true in the context of partitioning, and more so when the system under consideration comprises multiple surfactants. Part 1 of this two-part paper provides a detailed insight into the fundamentals of surfactant partitioning. Initially, the role of micellization in influencing single surfactant partitioning/distribution behavior between oil and brine is discussed, providing theoretical explanations for single surfactant system responses. The complexity of the systems examined increases with consideration extending to multi-surfactant environments, accompanied by discussion of idealized theoretical behavior. Subsequently, an idealized model to predict multi-component distribution responses between oil and brine is presented. To explore the model’s capabilities, experimental partitioning and micellization data collected from previous studies for two benzyl ammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16) is integrated into the model. Such integration permits investigation into the effect of surfactant concentrations, relative surfactant molar ratios and water cut on partitioning/distribution behavior.

In Part 1 of this two-part paper, a predictive model for multi-component partitioning was developed based on knowledge of individual component micellization and partitioning characteristics. In Part 2, the model’s validity is assessed through comparison with experimental partitioning data for an 1 wt.% NaCl brine:toluene system containing mixtures of two benzylammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16). Following model validation, the implications of the experimental partitioning behavior on corrosion inhibition performance are examined via rotating cylinder electrode (RCE) experiments. Through selected experiments, the important role of each of the two surfactants and their relative molar concentration in influencing overall corrosion inhibition performance is examined. While BAC-C12 exhibited poor inhibition in isolation, when combined with BAC-C16 at specific molar ratios, BAC-C12 played a crucial role in retaining the longer chain surfactant in the aqueous phase. This response enabled BAC-C16 (the more effective surfactant corrosion inhibitor) to work synergistically with BAC-C12 to suppress carbon steel corrosion more effectively than the two components alone under these particular conditions.

Volatile Corrosion Inhibitor (VCI) packaging has wide acceptance in the logistics world as an effective means for the protection of metal fabricated parts during shipping and storage. The utilization of VCI packaging for metals other than steel is still a challenge. Customers are reliant on packaging suppliers to provide them with a technical solution to their unique parts yet there are no standard test methods to prove that their offering is going to work for their alloy or part. This paper discusses the application of the well-understood, TL8135-002 Vapor Inhibiting Ability (VIA) test on a variety of non-steel specimens, including copper, brass, zinc, and aluminum.

Water Treatment Dosage Control and Relationship to Performance

Product Number: 51395-95260-SG

Author: J.E. Hoots

Publication Date: 1995

New methods for monitoring scale and corrosion inhibiting water treatment programs have been developed. These new patented methods utilize the measurement of system consumption of actives in the treatment program by fluorescence analysis.'-' The applied dosage of treatment program and the amount of actives available to the system are measured with inert fluorescent tracers added to the treatments.

System consumption of actives is defined as the difference between the amount of actives added and remaining in the system. 2,5- 7 Consumption measurements determine changes in the whole operating system (not a simulated, small portion of the system). Consumption measurements can also be made on individual portions of the system (heat exchangers). Changes in consumption of inhibitors and dispersants can .be related to changes in system operating conditions and performance. Reducing consumption of actives or maintaining consumption within a specified range can be related to optimization of the operation of the cooling system and treatment program.
