Publication number: 20140206902Abstract: The invention relates to a method for urea production and to a urea production plant wherein ammonia emission in the final step of forming urea prills is reduced. In the method, the concentration of a urea solution is performed in at least three consecutive concentration steps and the residence time of urea melt leaving a last concentrator to the prilling tower is minimised. This can be achieved by placing the last concentrator in adjacency with a urea melt inlet of the prilling tower, such as above the prilling tower. In this way, the ammonia emission in the prilling tower can be reduced by as much as 50% compared to the conventional urea production plants. The invention further relates to a method for reducing ammonia emission in the prilling tower of an existing urea production plant.Type: ApplicationFiled: August 17, 2012Publication date: July 24, 2014Applicant: STAMICARBON B.V.Inventor: Johannes Henricus Mennen

Publication number: 20140197074Abstract: Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.Type: ApplicationFiled: January 14, 2013Publication date: July 17, 2014Applicant: Saudi Arabian Oil CompanyInventors: Abdennour Bourane, Omer Refa Koseoglu, Zinfer Ismagilov, Svetlana Yashnik, Mikhail Kerzhentsev, Valentin Parmon
