Abstract

The present invention refers to a portable analysis system that, from analytical methodologies set based on digital images acquired by portable devices and accessories developed in an expedited way, allows the performance of the analytical test without technical deepening by the executor of the analysis. Such methodologies allow the evaluation of chemical species relevant to the O&G sector, for following up compositional parameters in aqueous samples and analytical monitoring of production and effluent treatment. Thus, a quick implementation is possible considering eventual diagnoses associated with the parameters of interest and following up of different processes. The application can be in any laboratory present in an operational unit, whether offshore or onshore, as well as it can be used for direct measurement in the field, depending on the necessary environmental and operating conditions.

Claims11

Dependent claims

A portable analysis system comprising:

a chamber configured to:
hold a reaction mixture between a sample and a reagent solution inside the chamber;
and
receive artificial light and avoid contamination from ambient light;
and
a camera outside of the chamber and configured to capture digital images of the reaction mixture inside the chamber,
wherein the system is configured to:
analyze the digital images of the reaction mixture for a reaction mixture property, wherein the reaction mixture property comprises color, turbidity, or combinations thereof;
and
determine a sample property using the analysis of the digital images, wherein the sample property comprises alkalinity, analyte concentration, or combinations thereof.
