The present disclosure provides methods for determining adsorption isotherms for complex mixtures. In at least one embodiment, a method for obtaining adsorption isotherms for liquid mixtures includes providing a column comprising an adsorbent. The method includes delivering a composition to the column, the composition comprising a multi-component feed and a solvent. The method includes collecting a sample from the column and introducing the sample to a two dimensional gas chromatograph to determine a time-series concentration of one or more components of the sample. The method includes integrating the time-series concentration of at least one of the one or more components to determine an isotherm of the at least one component. The method includes obtaining quantitative information of the at least one component, based on the isotherm of the at least one component.

The present invention relates to a method and system for measuring total chloride content in a process product stream. In particular, the present invention relates to a method of measuring hydrogen chloride and organochloride content, in situ, for a gaseous refinery process product stream. This method allows for measurement of hydrogen chloride and organochloride content in a single test method, which allows for optimised performance and maintenance schedules for chloride guard beds used within the refinery process.

A relief valve in a hydrocarbon site is shown. The relief valve is disposed within a housing. The housing includes a first engagement component coupled with a valve spring and a second engagement component axially aligned with the first engagement component. The second engagement component is configured to engage with the first engagement component during an operation cycle to translate the stem along the axis in response to the pressure within the relief valve being above the predetermined threshold. In some embodiments, the second engagement component is formed at least in part of a carbide substrate.

The present invention addresses to a method for characterizing water produced in oil samples containing water with contents below 0.5%, by measuring the analytes of interest directly in the oil containing the emulsified water. For this, it is necessary to carry out filtrations to remove possible suspended solids, since they may interfere with the composition of the water. The method proposed in the present invention provides methodologies with and without interference in the equilibrium by washing the oil with distilled water, measuring the analytes of interest directly in the oil.

The present invention addresses to a method for analyzing and detecting solids in emulsions, oil and derivatives thereof even in the presence of high contents of water (>5% v/v), which is based on the absorption and scattering of light by solids suspended in solution.

The application of the method of this invention contributes to greater reliability in terms of control of BSW (oil quality) and OGC (water to be treated and discarded). Additionally, there is the possibility of controlling the dosage of products such as scale inhibitors and naphthenates inhibitors, optimizing the dosage and minimizing operational occurrences associated with the formation of deposits. These eventually lead to equipment clogging throughout the process.

Disclosed is a method for dosing iron ions, by spectrophotometry, especially ferric and ferrous ions, contained in a used lubricating composition, especially a lubricating composition of a marine engine. The invention also relates to a kit for implementing the method.

A system and a method for determining the relative value of a naphtha stream is provided, by conducting analysis on the crude oil sample, after which modules or steps are performed to estimate the total liquid yields, estimate raw product yields, normalize raw product yields, determine the value of each fraction based on predetermined values, and calculate the total value of the naphtha stream.

The present disclosure relates to a method for determining a water cut value of a composition comprising a hydrocarbon. In some embodiments, the disclosure relates to an apparatus for determining the water cut value of the composition that comprises one or more of a capacitance probe, a temperature probe, a salinity probe, and a computer.

Method(s) and a system for predicting the refining characteristics of an oil sample are described. The method of predicting the refining characteristics, such as distillate yield profile, processability, product quality or refinery processing cost, may include development of a prediction model based on regression analysis. The method may further include determining the physical properties of the oil sample and predicting the refining characteristics based on the developed prediction model. The determination of the physical properties of the oil sample includes determining at least one of Conradson Carbon Residue (CCR) content, Ramsbottom Carbon Residue (RCR) and Micro Carbon Residue (MCR).
