Abstract: The invention generally relates to detecting an analyte in a medium. In certain aspects, the invention provides systems and methods for detecting an analyte in a medium comprising one or more light-emitting diodes, each operating at a single wavelength in a deep ultraviolet (UV) range for excitation of a target in a medium and a plurality of semiconductor photodetectors. The system is configured such that each semiconductor photodetector detects only a subset of emission from the excited analyte in the medium. In some examples, systems and methods of the invention comprise a light-emitting diode and a semiconductor photodetector for detection of the absence or presence of a non-specific contaminant.

Abstract: The present invention refers to a method for online monitoring, without the need for sampling and in real time, the precipitation of inorganic salts in aqueous streams related to the petroleum industry. This method is based on the use of the NIR technique with the aid of the FBRM technique. The NIR technique makes it possible to collect spectra and monitor the variation in absorbances, concerning the formation of particles of inorganic salts in the aqueous solution, while the FBRM technique provides the number and size of precipitated particles through the reflection of light emitted by a beam of Incident light in aqueous systems in the presence of different solvents, pH conditions, supersaturation, temperature and pressure. Thus, a set of collected NIR spectra is correlated with data provided by FBRM through a mathematical (chemometric) treatment and mathematical models based on artificial neural networks combined with principal component analysis were employed to estimate the quantity and size distribution of particles precipitated over time. The application of these process analyzers helps to understand the formation and growth of inorganic salt particles from the produced water (rich in carbonates and sulfates), which can precipitate at different stages in oil production and transportation facilities.

Abstract: A sensing system includes laser diodes with Bragg reflectors generating light having an initial light intensity and one or more near-infrared optical wavelengths. The laser diodes are modulated with a pulsed output with 0.5 to 2 nanosecond pulse duration. A beam splitter receives light from the laser diodes, splits the light into a received sample arm light directed to an object and a received reference arm light. A detection system includes a second lens and spectral filters in front of a photodiode array. The photodiode array is coupled to CMOS transistors and receives at least a portion of the received reference arm light and generates a reference detector signal. The detection system is synchronized with the laser diodes. A time-of-flight measurement is based on a comparison of the sample detector signal and the reference detector signal and measures a temporal distribution of photons in the received reflected sample arm light.

Abstract: An environmental emission monitoring system may include satellites configured to sense GHG emissions data for an AOI, and a server. The server may be configured to obtain the sensed GHG emissions data from the satellites, obtain geospatial positions of stationary GHG emitting point sources within the AOI, and generate expected stationary GHG emission data for the stationary GHG emitting point sources within the AOI and based upon the geospatial positions. The server may also be configured to obtain geospatial path data for GHG emitting vehicles moving within the AOI, generate expected vehicle GHG emission data for the GHG emitting vehicles moving within the AOI and based on the geospatial path data, and compare a sum of the expected stationary GHG emission data and expected vehicle GHG emission data with the sensed GHG emissions data to identify any stationary GHG emitting point source and any GHG emitting vehicle outside of a respective GHG emission threshold.
