Abstract: Systems and methods for determining an inventory layer for material stored in a plurality of storage units. The amount of material stored in each storage unit is measured. The activity status of each storage unit is categorized. An inventory layer is then determined based on the amount of material stored in each storage unit and the activity status of each storage unit. One or more batch characteristics can also be identified. The inventory layer and/or batch characteristics can be used to identify potential volume reductions.

Abstract: The invention below shows a preferred method to make high quality base oil at unexpectedly high yields using a combination of hydrotreatment of high waxy feedstocks accompanied by hydroisomerization of the resulting wax to produce an extra high VI lube of greater than 140VI and at least ?18 deg C. pour point or less. The preferred combinations of conditions identified below can surprisingly lead to unexpectedly high yields. This allows the use of higher oil content (or lower wax content) feedstocks.

Abstract: A tool to assist decision-making in the logistics of bulk product transportation. For example, the tool may be used to solve a problem involving the transportation and the inventory management of crude oil, in which the transportation of crude oil between supply ports and discharge ports are performed by a fleet of ships. The tool is capable of handling a typical petroleum product transportation problem, which can be quite complex. The tool uses advanced modeling and optimization technology to find a solution (either optimal or near optimal) for the allocation of bulk products, vehicle routing, vehicle scheduling, and/or bulk product blending operations.

Abstract: The present invention relates to a process for improving a deasphalting unit process by producing an improved feedstream for the deasphalting process via ultrafiltration of a vacuum resid-containing feedstream. In particular, the present invention produces an improved quality feedstream to a solvent deasphalting process which results in improved deasphalted oil (DAO) production rates and/or higher quality deasphalted oils. The present invention can be particularly beneficial when used in conjunction with an existing deasphalting equipment to result in improved deasphalted oil (DAO) production rates and/or higher quality deasphalted oils from the existing deasphalting equipment without the need for significant equipment modifications to the existing deasphalting unit.
