Abstract

Flamboyant mirim gum is a galactomannan, extracted from Caesalpinia pulcherrima seeds, a legume family schrub. The main objective of this work was to propose a factorial experimental design to optimize the galactomannan extraction process from its seeds and evaluate its potential as a viscosifying agent for enhanced oil recovery (EOR). The galactomannan was characterized by FTIR, NMR, SEC, thermogravimetric analysis, elemental analysis, and rheology. Structural analyses confirmed the presence of the desired galactomannan content. The best yield obtained was 7.3% for initial seed mass and 24.6% for the endosperm. Rheological analysis showed that Flamboyant mirim gum is a promising alternative for EOR application in high salinity conditions. In addition, stability tests showed that glutaraldehyde can be considered a promising biocide for fluids containing galactomannan since it maintained the viscosity values of the systems for 42 days. Thus, the results confirmed the adequacy of the extraction procedure for obtaining galactomannan.

阻燃Mirim胶作为一种潜在的增稠剂的提取与评价

艳丽的米林胶是一种半乳甘露聚糖，从豆科灌木凯撒籽中提取。本工作的主要目的是提出一个析因实验设计，以优化从其种子中提取半乳甘露聚糖的工艺，并评估其作为提高石油采收率(EOR)的增粘剂的潜力。采用FTIR、NMR、SEC、热重分析、元素分析和流变学等方法对半乳甘露聚糖进行了表征。结构分析证实了所需的半乳甘露聚糖含量的存在。初始种子质量和胚乳的最佳产量分别为7.3%和24.6%。流变学分析表明，Flamboyant mirim gum是高矿化度条件下提高采收率的一种很有前景的替代方案。此外，稳定性测试表明，戊二醛可以被认为是一种很有前途的含有半乳甘露聚糖的流体杀菌剂，因为它可以将体系的粘度值保持42天。因此，结果证实了半乳甘露聚糖提取工艺的充分性。
