(EN) INTEGRATION OF SOLVENT DEASPHALTING, GASIFICATION, AND HYDROTREATING
(FR) INTEGRATION DE DESASPHALTAGE, DE GAZEIFICATION ET D'HYDROTRAITEMENT PAR SOLVANT
Abstract
(EN)
During the hydrotreating process, hydrogen sulfide and short chain hydrocarbons such as methane, ethane, propane, butane and pentane are formed. The separation of gas from hydrotreated liquid hydrocarbons is achieved using a stripper and a flash drum. High pressure steam or nitrogen is contacted with the hydrotreated liquid hydrocarbon material. This high pressure steam strips the volatiles, i.e., hydrogen, the volatile hydrocarbons, hydrogen sulfide, and the like, from the oil. The gaseous streams is then separated and cooled to remove condensables, including primarily water, short chain hydrocarbons, and hydrogen sulfide in the water. The condensables are advantageously sent to the gasifier, where the hydrocarbons are gasified, the water moderates the gasifier temperature and increases the yield of hydrogen, and where hydrogen sulfide is routed with the produced synthesis gas to the acid gas removal process.

Au cours d'un processus d'hydrotraitement, on forme de l'hydrogène sulfuré et des hydrocarbures à chaîne courte, tels que le méthane, l'éthane, le propane, le butane et le pentane. La séparation du gaz des hydrocarbures liquides hydrotraités est effectuée au moyen d'une colonne de stripping et d'un ballon de détente. De l'azote ou un flux à pression élevée est mis en contact avec le matériau d'hydrocarbure liquide hydrotraité. Ce flux à pression élevée élimine les produits volatiles, c'est-à-dire l'hydrogène, les hydrocarbures volatils, l'hydrogène sulfuré, et analogue, de l'huile. Le flux gazeux est ensuite séparé et refroidi, afin d'éliminer les produits condensables, notamment de l'eau, des hydrocarbures à chaîne courte, et de l'hydrogène sulfuré, de l'eau. Les produits condensables sont avantageusement envoyés au gazéifieur, dans lequel les hydrocarbures sont gazéifiés, l'eau modère la température du gazéifieur et augmente le taux d'hydrogène, l'hydrogène sulfuré étant acheminé avec le gaz de synthèse produit vers le processus d'élimination de gaz acide.
