摘要： A process for the catalytic oxidation of sulfur and nitrogen contaminants as well as unsaturated compounds present in a hydrocarbon fossil oil medium is described, the process comprising effecting the oxidation in the presence of at least one peroxide, at least one acid and a pulverized raw iron oxide. The process shows an improved oxidation power towards the contaminants typically present in a fossil oil medium, this deriving from the combination of the peroxy-acid and the hydroxyl radical generated in the reaction medium due to the presence of an iron oxyhydroxide such as a limonite clay, which bears a particular affinity for the oil medium. The process finds use in various applications, from a feedstock for refining until the preparation of deeply desulfurized and deeply denitrified products.
摘要翻译：描述了一种用于催化氧化硫和氮污染物以及烃化石油介质中存在的不饱和化合物的方法，该方法包括在至少一种过氧化物，至少一种酸和粉碎的生铁存在下进行氧化氧化物。该方法显示出对于通常存在于化石油介质中的污染物的改善的氧化功率，这源于由于存在羟基氧化铁如褐铁矿粘土而在反应介质中产生的过氧酸和羟基自由基的组合，其对油介质具有特异性亲和力。该方法可用于各种应用，从用于精制的原料直到深度脱硫和深度反硝化产物的制备。

摘要： A subsea primary separating vessel (2, 22) is installed close to the wellhead (1, 31) of an oil producing well to effect primary separation of the liquid and gas phases of the fluids produced. A line (3, 23) connected to the top of the separating vessel allows separated gas to flow to a gathering vessel (8, 28) located at any gathering centre. At least one flow line (4, 5, 24) connects the lower part of the separating vessel to a vessel (9, 29) located at any gathering centre. When the volume of liquid phase which separates out within the at least one flow line begins to exert a back pressure which adversely affects production from the well, high pressure gas can be injected into the flow line(s) for a specific period of time in order to promote the flow of liquid gas to the vessel (9, 29). If it is desired that flow efficiency should be increased, a mechanical interface driven by the high pressure gas may be used to encourage flow of the liquid phase.
摘要翻译：靠近油井的井口（1,31）安装海底初级分离容器（2,22），以使所生产的液体和液相的初级分离。连接到分离容器的顶部的管线（3,23）允许分离的气体流到位于任何收集中心的收集容器（8,28）。至少一个流动管线（4,5,24）将分离容器的下部连接到位于任何收集中心处的容器（9,29）。当在至少一个流动管线内分离的液相的体积开始施加对井的生产产生不利影响的背压时，可以将高压气体注入流体管线一段特定的时间段以促进液体气体流向容器（9,29）。如果希望提高流动效率，则可以使用由高压气体驱动的机械界面来促进液相的流动。

摘要： This invention relates to a method and equipment to assist the flow of offshore oil production. At least three production lines (14, 15, 16) are used, which are interconnected close to offshore well-heads or manifolds (1) forming two U-shaped lengths (2 or 3) of pipe acting as circuits for passage of the hydrocarbon mixture procuced. A mechanical interface (12) is periodically inserted into one (14 or 15) of the U-shaped branches of pipe and, driven by high pressure gas, travels along the pipe length (2 or 3) to return to the gathering centre (20). In its passage it pushes along the volume of hydrocarbon mixture which has accumulated in the pipes (14/16 or 15/16).
