en.Wedoany.com Reported - Scientists at the Institute of Geology and Oil and Gas Technologies of Kazan Federal University (Kazan Federal University, KFU) have developed a biopromoter based on castor oil that can stabilize associated petroleum gas hydrate particles for a long time, providing a solution to the problem of long-term storage.

Previously, sodium dodecyl sulfate was commonly used to generate gas hydrates. Although it accelerates the process, it has drawbacks: it forms loose particles leading to rapid gas leakage and generates a large amount of foam during extraction. The castor oil-based biopromoter overcomes these issues, with particles losing less gas and no foam, making operation easier.

Another advantage of this biopromoter is its environmental friendliness. Castor oil is a renewable and biodegradable raw material. Tests show that the new biopromoter is five times less toxic than synthetic surfactants, which is particularly important for oil and gas extraction in ecologically vulnerable regions of Russia. The developers emphasize that this solution aligns with green chemistry principles and helps reduce the environmental load when processing associated petroleum gas.
