Can someone help me with these question especially parts d) and e)
thanks

In order to meet pollution standards, oil refineries remove trace amounts of sulfur from the crude oil This sulfur is often in the form of HbS and SO. A process has been suggested to convert these compounds into sulfur and water using the following reaction 2HS(g+ SO,(g) 3S(s)+2H,O(g) A schematic of the facility is shown in Figure I on page 2 Due to the difficulty (and cost) of achieving high purity, the input streams (Fi and F2) both contain signifcant concentrations of CO2 The input feeds (Fi and F2) are blended to achieve a stoichiometric ratio of H.S and SO2 and are subsequently combined with a recycle stream and fed into the reactor. The solid sulfur is completely removed in the solids separator while the water is completely removed in a condenser The stream leaving the condenser splits into a purge stream and the recycle stream. The flow rate in Fi is 100 mol'sec and the process achieves a 95% conversion of H2S In addition, the recycle to feed ratio ficant 15 Hl

Explanation / Answer

a) The recycle stream is that the return of the material from downstream of the process unit back to the process unit . The purpose of it is to be the maximum conversion of a reactant into the product present there that means to achieve the maximum percentage of the consumption of the wanted materials and in order to prevent the accumulation in the system.

b) The purge stream is a stream bled off to remove an accumulation of inerts or unwanted material that might otherwise build up in the recycle system. The purpose of it is to maintain the purity level.
