WebClaus plant. To achieve 99 percent sulphur recovery, the tail gas from the second Claus bed is fed directly to the reactor bed containing the direct oxidation catalyst. To achieve 99.5 … WebHydrodesulfurization ( HDS ), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. [1] [2] [3] The purpose of removing the sulfur, and creating products such ...
Sulphur Recovery Unit in Refinery Common Problems and Optimization
WebFigure 1 2 shows a typical process flow scheme of a 2-stage straight-through 3 Claus sulfur recovery unit (SRU). Acid gas from the acid gas removal (AGR) process, along with … WebTypical Claus sulfur recovery unit. CW = Cooling water. STM = Steam. BFW = Boiler feed water. In addition to the oxidation of H 2 S to SO 2 and the reaction of SO 2 with H 2 S in the reaction furnace, many other side reactions can and do occur in the furnace. Several of these possible side reactions are: CO 2 + H 2 S → COS + H 2 O (4) fishingbuddy钓鱼助手怎么安装

WebIf the sulfur recovery unit is located in a crude oil refinery, the typical reheat scheme uses 3536 to 4223 kPa (500 to 600 psig) steam for reheating purposes. Most plants are now built with two catalytic stages, although some air quality jurisdictions require three. From the condenser of the final catalytic stage, the WebA simple schematic is shown in Figure 1. The main reaction in the reaction furnace has two steps. One is a fast, irreversible and highly energetic exothermic reaction: H2S + 3/2 O2 -- … WebSulphur recovery unit The acid gas lines from the amine regeneration unit (ARU) and the sour water treating unit (SWTU) are routed separately to the SRU. The SRU converts hydrogen sulphide (H2S) to liquid sulphur and ammonia (NH3) to nitrogen. Figures 1 and 2 show simplified process flow diagrams. The SRU typically consists of a Claus thermal ... fishing bull creek austin
