There is provided a method for determining Total Acid Number (TAN) in a fluid fossil fuel, such as a crude oil, comprising: separating said fluid fossil fuel by liquid chromatography into a plurality of fractions, comprising at least one acidic fraction; determining boiling point distribution of said crude oil, of said acidic fraction, and of said polyacidic fraction by simulated distillation (SD); and correlating said boiling point distributions to acid molecular weights to determine the TAN.

Determining acid concentration by boiling point

The present application provides a method for measuring coking propensity of a fossil fuel, comprising mixing an iron powder with a fossil fuel, wherein the iron powder has an average particle size of less than or equal to 100 &#x3bc;m; reacting the iron powder with the fossil fuel at a temperature and a pressure sufficient to allow coking for a period of time; separating a supernatant and a solid product after said coking; and analyzing the solid product for carbon content, wherein the carbon content is proportional to the coking propensity. There is also provided is a method for measuring effectiveness of a coking inhibitor.

Measuring coking propensity

Methods and apparatus relate to measuring corrosion rate. Flowing corrosive fluid contacts a metal coupon or object and results in an effluent stream. The effluent stream contains metal from the object due to reaction of constituents in the fluid with the metal. Analysis of the effluent stream measures concentration of the metal therein. Since the concentration of the metal in the effluent stream is indicative of mass loss from the object, calculations provide the corrosion rate utilizing weight of the metal that is eluted, surface area of the object and exposure time of the object with the corrosive fluid.

Corrosion rate monitoring

A hydrocarbon desulfurization system that circulates fluidizable solid particles through a fluidized bed reactor, a fluidized bed regenerator, and a fluidized bed reducer to thereby provide for substantially continuous desulfurization of a hydrocarbon-containing fluid stream and substantially continuous regeneration of the solid particles. A novel transport system is employed for transporting the solid particles between the reactor, the regenerator, and the reducer. The transport system uses close-coupled vessels and gravity flow between various vessels to minimize equipment cost and particle attrition.

Desulfurization process

A method and/or apparatus for efficiently operating a combustion device including at least one control zone, with each control zone including at least one burner assembly, is disclosed and includes a) individually supplying fuel to each of the burner assemblies in each of the control zones, b) individually measuring a separate combustion characteristic of the collective combusted gas from each of the burner assemblies in each of the control zones, and c) individually adjusting the flow of air to each of the burner assemblies in response to the value of the combustion characteristic corresponding to each of the control zones to keep the value of each separate combustion characteristic within a predetermined range. In a preferred embodiment, primary air and secondary air are separately supplied and controlled to each of the burner assemblies in each of the control zones in response to the value of the combustion characteristic corresponding to each of the control zones.
