摘要： A method for analyzing the fouling tendency of a bottoms slurry in a fluidized catalytic cracking unit, the method comprising the following steps:

(a) subjecting a sample of the bottoms slurry to a selected increased pressure above atmospheric pressure and to a selected temperature corresponding to a bottoms slurry temperature at which the bottoms slurry is proposed to be maintained in the fluidized catalytic cracking unit;
(b) maintaining the sample at the selected increased pressure and selected temperature for at least about two hours;
(c) cooling the sample and reducing the pressure;
(d) homogenizing the sample to produce a homogenized sample;
(e) extracting relatively higher molecular weight materials from the homogenized sampling and
(f) analyzing the extracted relatively higher molecular weight materials for at least one equality

wherein the steps (e) and (f) are carried out by:

(g) adding from about three to about five parts by weight of a solvent composition to one part by weight of a measured amount of the homogenized sample, thereby to form a liquid phase containing relatively low molecular weight slurry components and a precipitate phase containing relatively high molecular weight slurry material as a precipitate;
(h) separating out the precipitate; and
(i) analyzing the precipitate for at least one quality.

摘要： Disclosed is a plug valve (10a) adapted to be placed in a chamber or vessel containing fluidized particles to control flow of the fluidized particles between the chamber or vessel and the open end of a conduit which has a contained purging system in a sealed space between the valve stem (14a) and guide tube (12a) effective to keep the fluidized particles out of the space. A purging medium is provided under pressure to the sealed space as a backup and only purges the space of fluidized particles which enter it due to leakage of one or both of the stuffing boxes (36). Other features of the plug valve are described.

摘要： A fluid catalytic cracking process and apparatus is described which includes a high temperature stripper (hot stripper) to control the carbon level and sulfur on spent catalyst, followed by catalyst cooling to control the regeneration inlet temperature. The high temperature stripper operates at a temperature between 55°C (100°F) above the temperature of a catalyst-hydrocarbon mixture exiting a riser and 816°C (1500°F). The regenerator inlet temperature is controlled to obtain the desired regeneration temperature, regenerator outlet temperature, and degree of regeneration. The regenerator is maintained at a temperature between 55°C (100°F) above that of the catalyst in the high temperature stripper and 871°C (1600°F). The present invention has the advantage that it separates hydrogen from catalyst to eliminate hydrothermal degradation, and separates sulfur from catalyst as hydrogen sulfide and mercaptants which are easy to scrub. The catalyst cooler enables the regenerator and high temperature stripper to be run independently at respective desired temperatures.

摘要： On décrit un procédé et un appareil de craquage catalytique fluide comprenant une colonne de rectification à haute température (une colonne de rectification à chaud) permettant de commander le niveau de carbone et le soufre sur le catalyseur épuisé, suivie par un refroidissement du catalyseur pour commander la température d'entrée de régénération. La colonne de rectification à haute température fonctionne à une température comprise entre 55°C (100°F) au-dessus de la température du mélange catalyseur-hydrocarbure sortant d'un tuyau montant et 816°C (1500°F). On règle la température d'entrée du régénérateur de façon à obtenir la température de régénération, la température de sortie du régénérateur et le degré de régénération voulus. Le régénérateur est maintenu à une température comprise entre 55°C (100°F) au-dessus de celle du catalyseur se trouvant dans la colonne de rectification à haute température et 871°C (1600°F). L'avantage de la présente invention est que l'hydrogène est séparé du catalyseur pour éliminer la dégradation hydrothermale et que le soufre est séparé du catalyseur de même que le sulfure d'hydrogène et les mercaptans que l'on peut aisément enlever. Le refroidisseur de catalyseur permet au régénérateur et à la colonne de rectification à haute température de fonctionner indépendamment l'un de l'autre à des températures respectives choisies.

摘要： A sample of a hydrocarbon oil containing asphaltenes is chromatographically analyzed by forming a mixture of the oil with a weak solvent. The mixture is passed in contact with a column of a stationary phase of fine solid particles of fully functionalized material, followed by a weak solvent. The solvent, after recovery from the column, is analyzed for aromatics by UV-absorption of UV radiation in the range 200 to 500 nm. The absorbance of the UV light by the irradiated eluents across the UV wavelength range is monitored and the integral of absorbance is derived as a function of photon energy across the wavelength range. The magnitude of the derived integral in at least one time interval corresponding with aromatics in the eluent from the stationary phase is measured as an indication of the level of aromatics in the oil sample. The weak solvent may be followed by a strong solvent which, in turn, may be followed by a strong solvent which is modified by the addition of a hydrogen bonding solvent. The solvents are analyzed for saturates, aromatics, polar compounds and any asphaltenic materials by the combination of the UV-absorption measurement and a mass sensitive measurement which measures the combined level of the saturates, aromatics, polars and any asphaltenic compounds present. Equipment to perform the foregoing analysis is also described. The analysis can be used for evaluation of an oil and/or for on-line regulation of an oil refining process.
