Perlite, Celite, polyester fibre, ceramic paper, glass wool, and woven glass fibre were tested as filterbeds in the enhanced filtration scheme described in the main text. As described in the main text, crude PGO could be optimally filtered with ceramic paper, while crude LFGO required a different filterbed.

Crude oil operations in refineries are characterized as a hybrid system since it contains both discrete-event and continuous processes, and it is extremely difficult to schedule such a system. For scheduling such a system, initially the discrete tasks to ...

Crude oil distillation is an energy-intensive operation, especially with respect to fired heating. The atmospheric and vacuum distillation units all together consume 35–45 % of the total primary energy used in a refinery ( Szklo and Schaeffer, 2007 ). Heat integration is routinely implemented to reduce heat demand, and thus utility costs.

example a paraffinic crude has d1<0.76 and d2<0.93, an aromatic crude has d1>0.80 and d2 between 0.93 and 0.975, an asphaltic crude has d1>0.78 and d2>0.975, and so on. This is obviously related to the relative abundance of hydrogen and carbon. Nevertheless, there is a need for a unique number, rather than a range, to characterize the type of crude
