Since the Shell plant / process has hundreds of integrated steps, and feed back loops, key word being integrated, it would be a very complex 100 plus variable by 100 plus equation matrix (think Matrix algebra, Matrices) to try and calculate the net energy cost difference in swapping out the Syn gas formation step. I doubt Shell would even attempt it in such a new, huge integrated facility that has "thousands of Shell patents and 30 years of work invested in the entire complexes design.

The energy balance in the single syngas formation reactor step, is not as simple as just looking at the operating temperature. It involves backing up and looking at the energy input to make the O2 gas for the Shell reactor first. Making pure O2 is energy intensive itself.

Energy balance in a reactor is calculated this way:

Pretty simple calculation, LOL.

Take a look at #3, for a simple english version of a non-reactive energy balance just for flow in and out of a system:
