Abstract: Process for evaluating a plurality of refinery feedstocks, by providing an array of refinery feedstocks, the array having at least a plurality of different refinery feedstocks, and fractionating each of the refinery feedstocks in the array, either in parallel or in a rapid serial fashion, to produce a further array having a plurality of fractions with different chemical and/or physical properties, each fraction being representative of a process stream that might be present in a refinery. Each of the plurality of fractions is analyzed to determine one or more chemical and/or physical properties of the fractions, the analyzes being performed at least partially in parallel.
