Draw a block flow diagram for a petroleum refinery that includes three different separation processes, five different conversion processes along with one or more finishing processes, and one supporting process to produce altogether nine commercial fuels and materials from a sour crude oil. clearly label all the feedstocks processes, and products on your diagram including the type of process (separation, conversion, finishing, and support) and the intermediate products. make sure that all processes are correctly connected. write down the principal objectives of this refinery. draw a block flow diagram for a petroleum refinery to maximize the diesel fuel yield from a paraffinic crude oil. in your flow diagram, include only the processes that are absolutely necessary for maximum diesel yield and make sure that the whole crude is converted completely to commercial (sellable) products in this refinery.

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.
