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
