Glucose (G) is converted to fructose (F) as shown in the diagram below. Both sugars have...
Propane is catalytically dehydrogenated to produce propylene by passing it over a granuar solid catalyst. In parallel with the main gas-phase reaction of propane dehydrogenation, side reaction to methane and carbon occurs: C,H,C,H +H A single-pass conversion of propane of 80%Is achieved in the reactor. Out of the propane reacting, 20% reacts according to the side reaction. The reactor effluent gases undergo a two-stage separation. In the first stage all hydrogen and 90% of the methane is separated, in the...
4. 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 H2S and SO2. A process has been suggested to convert these compounds into sulfur and water using the following reaction: 2H,ste)+S0,(g)- 3s6)+2H,og) A schematic of the facility is shown below. Due to the difficulty (and cost) of achieving high purity, the input streams (Fi and F2) both contain significant concentrations of CO2. The input...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
