The KEY PROBLEMS OF THE EXISTING COMMERCIAL PROCESS
FOR CUMENE-BASED PHENOL AND ACETONE PRODUCTION
APPEAR TO BE A CONSEQUENCE OF SIDE PRODUCTS
FORMED AT THE CUMENE OXIDATION STAGE:
- |
Dimethyl benzene alcohol (DMBA) |
- |
acetophenone (AP) |
- |
dicumylperoxide (DCP) |
FOCUS OF THE STUDY
Search for Fundamentally Different Chemical Approach Search for Different Process Implementation
OUTCOME OF THE STUDY:
- |
Reduction in the Number of Chemical Stages from 7 to 3 |
- |
Reduction in the Process Stages from 9 to 5 |
New Method Suggests Separation of Cumene Oxidation Products via a Continuous Adsorption-Desorption to Obtain Products therein Contained such as AP, DMBA, DCP, CHP.
ILLA considers the so-called "WASTE-LESS ECONOMICAL PHENOL PROCESS (WEPP)" to be the future of phenol process
The Use of Continuous Adsorptive Separation of Cumene Oxidation Products Allows One to
- |
appreciably simplify the process chemistry |
- |
totally prevent formation of phenol tar in cumene hydroperoxide (CHP) cleavage stage and achieve a cumene usage coefficient close to theoretical value of 1285-1287 kg per ton of phenol |
- |
reduce the number of chemical stages in the process |
- |
simplify the acid CHP cleavage process and make it safe and also achieve 100% selectivity in this stage |
- |
rearrange an earlier multicolumn and extremely utilities consuming system of CHP cleavage product fractionation into a compact utilities saving system, specifically twice reduce the number of columns and steam consumption |
