Enhim
The Research and Development Center (R&D Center) of Enhim (part of the NEC Group) has summarized its 2025 results, marking significant improvements in working conditions and the expansion of the laboratory’s analytical capabilities.
During the year, laboratory specialists obtained two invention patents, certified two analytical methods, prepared ten R&D reports, and analyzed 425 samples of fire-resistant turbine oil.
The key achievement was the certification of a new method for determining the acid number, which made it possible to completely eliminate the use of toxic reagents.
“There is no longer any need to prepare an alcohol–benzene mixture to determine the acid number,” noted Ekaterina Sonina, Head of the R&D Center. “First, the absence of toxic reagents reduces the hazards associated with the analysis; second, it makes the work of laboratory staff more comfortable. Titration reagents can now be handled not only in a fume hood, but also on standard laboratory benches.”
The new method is not only safer but also more efficient: the measurement range has been expanded fr om 1 to 16 mg KOH/g, enabling accurate analysis of oils with a high degree of degradation.
“Our achievements benefit both Enhim’s production laboratory and our partners,” emphasized Ekaterina Sonina. “This method allows us to determine the precise acid number of heavily degraded fire-resistant oils, making operational studies of such oils more accurate.”
Subsequently, a method for determining the pH value of the aqueous extract of fire-resistant oil was certified. The introduction of mechanical stirring of the sample resolved the issue of poor interlaboratory reproducibility, significantly improving analytical accuracy.
Two invention patents hold a special place in the R&D Center’s portfolio. The first relates to a method for determining isomeric composition — a parameter that affects corrosive activity.
“The developed method makes it possible to assess product resistance to hydrolysis and identify the primary component of fire-resistant oil. This enables indirect evaluation of such parameters as hydrolytic stability and corrosive activity. Through our developments, we are introducing advanced analytical methods into the production of fire-resistant oil. Many more plans lie ahead to further enhance analytical control and product manufacturing,” Ekaterina Sonina added.
The second patent concerns the determination of the purity of fire-resistant turbine oil. The new method enables more accurate and reliable detection of foreign mechanical impurities, which is critically important for maintaining equipment operability.
It is important to note that the Enhim R&D Center does not lim it itself to delivering ready-made solutions. Laboratory specialists regularly support colleagues from the main production site, provide консультации at all stages of manufacturing, and assist in adapting new methodologies to the practical needs of production workshops.
