09 July 2013 Hello again Attached, you can find the “Hysys” simulation case (Fig. 2 in our paper). Note that in the original UniSim file there is a PIPESYS extension for calculating the pressure drop as function of flow between syngas unit and FT reactor, but since my current Hysys version does not support that extension, I removed it from the UniSim case and tried to have the same SS values as shown in Fig. 2.
