Title: Methods for optimal usage and improved valuation of corrosive petroleum feedstocks and fractions
Inventor: CHIMENTI ROBERT JOHN LOUIS
IPC: G01N31/00
Filed: 2000-03-21
Granted: 2009-06-02
Abstract: The invention is a method to improve the prediction of the corrosivity of organic acids in petroleum crudes, feedstocks and distillation fractions by providing a more accurate, repeatable, and rapid means of determining the TAN from the IR spectrum of the material. The method can be easily practiced in refinery, terminal, and assay laboratories.  It can be used in conjunction with models and hardware to optimize the usage and improve the valuation of corrosive feed stocks. The invention can be implemented on-line for blending optimization. It comprises the steps of irradiating a heated petroleum sample with IR  radiation to produce its IR absorption spectrum, and predicting the TAN from the spectrum using a linear, multivariate regression model. The IR  TAN value is then used as input to blending, valuation, and corrosion models.

Abstract: In a vehicle with bumper which is attached to the vehicle transverse to the longitudinal direction of the vehicle via a deformation element (10) the deformation element (10) exhibits two first side walls (28, 30) that are spaced apart, and are joined to second side walls (40, 42) that are spaced apart. The first and second side walls (28, 30, 40, 42) feature first and second grooves (48a,b, 50a,b; 50a,b, 54a,b) that run transverse to the longitudinal direction of the vehicle and are arranged in pairs opposite each other, each in a common plane. The first grooves (48a,b, 50a,b) extend over the whole breadth of the first side walls (28, 30) and the second grooves (52a,b, 54a,b) extend over only a middle part of the second side walls (40,42), leaving a region free at both edges.  The first grooves (48a,b, 50a,b) are arranged in pairs in first planes and the second grooves (52a,b, 54a,b) are arranged in pairs in second planes situated between two subsequent first planes.   The deformation element exhibits a high capacity for absorbing the energy of deformation on collision with the bumper, and leads to essentially symmetric deformation.

Abstract: Apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler comprises plural vertical, impact type particle separators made of cooling tubes located within the CFB in a plurality of staggered rows. One embodiment employs a plurality of stacked, slip fit elements having apertures which accept the cooling tubes. The slip fit elements cooperate with one another to form a collecting channel, typically U-shaped, which separates particles from flue gases conveyed across the particle separators. Shiplap joints in between the individual slip fit elements prevent gas and solids from leaking therebetween and allow for thermal expansion. Alternatively, the impact type particle separators comprise cooling tubes connected to one another to form a unitary structure. Pin studs welded to the cooling tubes and covered with a coating of refractory; ceramic tiles; metal or ceramic spray coatings; metal or ceramic castings; weld overlay; and/or shields provide erosion resistance.

Abstract: L'invention concerne un séparateur de signal résolvant un brouillage colinéaire rencontré dans une station de base de système de communications sans fil par l'exploitation des caractéristiques d'évanouissement généralement plates des signaux entrants. La présente invention emploie à cet effet la diversité obtenue par l'utilisation des éléments du réseau d'antennes possédant des polarisations diverses. Un abaisseur de fréquence RF produit un séparateur de signal doté d'une bande de base, d'échantillons numériques à temps discret d'oscillogrammes de signal, reçus à une ou plusieurs paires d'éléments d'antenne à polarisations diverses. Le séparateur de signal pondère et combine les signaux de bande de base provenant des signaux reçus polarisés horizontalement et verticalement produits par l'abaisseur de fréquence RF, afin de déterminer quels signaux émanent de quels utilisateurs. Le séparateur de signal utilise des coefficients de polarisation fournis par un calculateur de coefficients. Ce dernier, afin de produire les coefficients de polarisation, est couplé de manière à recevoir un ensemble de coefficients d'évanouissement de voie provenant d'un estimateur de voie. Les estimations des coefficients d'évanouissement de voie peuvent être dérivés au moyen d'algorithmes de traitement de signal standards, grâce aux valeurs de crête et à la synchronisation connue entre les motifs d'entraînement. Le calculateur de coefficients calcule les coefficients de polarisation requis par le séparateur de signal au moyen d'une matrice de coefficient telle que la sortie du séparateur de signal soit égale au signal d'information de l'utilisateur.
