Evaluation of the antifoam dose to be injected at the Fraile Collection Center

Abstract

This work focuses on the evaluation of antifoams, specifically NDAF 100, used in the oil and gas separation process at the Fraile Collecting Center, part of the Western oil drilling and extraction company at Santa Cruz del Norte. The overall objective is to determine the appropriate dosage of antifoam to use in the crude oil collection and separation process at this facility. The injection dosage of antifoam at laboratory scale, the injection dosages for different flows using a mathematical model, and the economic impact of the results were evaluated. Laboratory tests were conducted with different concentrations of NDAF 100 (0 to 50 ppm) to observe its effect on degassing time. A dosage of 10 ppm of NDAF 100 was found to significantly reduce foam, optimizing separation and reducing costs. A simple square root-X regression model of dosage (ppm) vs. flow was obtained, and a potential savings of 2,751,145 CUP was identified if the appropriate dosage had been applied from the beginning of the installation. Injection of the NDAF 100 antifoam can be evaluated to improve the efficiency of oil-gas separation, and it is recommended that the antifoam dosage be adjusted according to operating conditions to avoid waste and improve production profitability.
