THE PRODUCTION OF CUMENE USING Zeolite …

Essentially all cumene produced worldwide is used as a feedstock in phenol plants, which convert it to phenol and acetone by cumene peroxidation. Therefore, the cumene and phenol markets are strongly tied. From 1993 to 1998, world cumene demand grew at a rate of 4.7%/yr, increasing from 5.6 million to 7.1 million t/yr.

Improving flowsheet convergence in HYSYS

Go to Simulation-Main Properties, and modify the Calculation Level on the "Calc Levels" tab. To force HYSYS to solve ADJ-1 before ADJ-2, set the calculations levels to 3500 and 4000, respectively. Checking tolerances are consistent. Often, the default tolerances in the recycle are not tight enough to ensure that the flowsheet properly convergences.
