From the Henry B. Gonzalez Convention Center, in San Antonio, Texas, USA, during the AMPP 2022 Annual Conference and Exposition, Inspenet TV was able to conduct this exclusive interview with chemical expert José Vera.
Vera, is a Ph.D. in chemistry and chemical engineer with more than 45 years of experience in the oil & gas area and on this occasion he gave the conference “Interpretation of the H 2 S eliminator (inhibitor). Results of laboratory tests using a kinetic model”.
During his lecture, he explained that a kinetic model was developed, implemented to assist in the interpretation of the H 2 S scavenger (inhibitor) test with results obtained from the CSTR with the continuous gas flow procedure. Using this kinetic model, parameters related to the kinetics of the H 2 S scavenger reaction can be extracted and used to qualify chemicals for a specific application. The kinetic model also simulates the effect of different test parameters on experimental results and can be used to extrapolate laboratory results to field conditions.
“One of the problems that occurs in the oil industry is that when they design new systems, offshore or inland, sometimes there is no H2 S in system, then, they do all the design assuming that there is not going to be H2 S throughout the useful life of the facilities, however, there is a problem and that is that the reservoirs begin to turn sour and this is due to the poor injection of water, which has bacteria and produces H2 S, over time it begins to grow and there comes a time when it is more than it can allow so much due to a lack of personnel security”, explains Vera.
