摘要:
A process to continuously prepare a hydrocarbon product having a specified desired sulphur content lower than 0.05 wt %, starting from at least two or more high-sulphur hydrocarbon feedstocks having a sulphur content of above 0.05 wt %, by (a) blending the two or more of the high-sulphur hydrocarbon feedstocks, to form a blended feed mixture; (b) reducing the sulphur content of the blended feed mixture in a hydrodesulphurisation (HDS) step; (c) obtaining a hydrocarbon fraction, having a reduced sulphur content, comprising the effluent of step (b) and determining the sulphur content of the hydrocarbon fraction; and (d) obtaining the final hydrocarbon product from the direct product of step (c) and adjusting the process to achieve that the sulphur content of the hydrocarbon product is close or equal to the desired sulphur content of the hydrocarbon product, wherein the production of the hydrocarbon product having the desired sulphur content is optimised by integrated control of the blending in step (a) and of the HDS unit operation in step (b), and wherein the sulphur content of the hydrocarbon fraction as determined in step (c) is taken into account.

A method, system and a computer program product for accurately predicting an output motion from a database of motion data based upon an input motion scenario are provided. A motion database is searched to find relevant existing motions. The selected motions, referred to as “root motions,” most likely do not meet exactly the input motion scenario, and therefore, they need to be modified by an algorithm. This algorithm derives a parametric representation of possible variants of the root motion in a GMP-like manner, and adjusts the parameter values such that the new modified motion satisfies the input motion scenario, while retaining the root motion's overall angular movement pattern and inter-joint coordination. The embodiment of the invention can accurately predict various human motions with errors comparable to the inherent variability in human motions when repeated under identical task conditions. The motions may be human or non-human such as other living creatures or robot motions.
