ITW has developed and patented a technology for polymer modification/dissolution.
ITW technology has been able to modify, as a first time ever, polymers in a butadiene unit.
This allowed the removal of a great portion of the polymer during the circulation of a patented chemical, thereby removing about 80% of the polymer which was originally present.
More importantly, the trays have been cleaned without the need for dismounting them, as was necessary in previous turnarounds.
Subsequent to polymer modification and online cleaning, ITW Improved Degassing/Decontamination technology achieved a fast and efficient compliance with safe entry conditions in confined spaces.
Some additional petrochemical applications of the technology include the following units:
As well as any other petrochemical unit wherein polymer formation/removal impairs operations or increases downtime.
This new technology may open up new scenarios in refinery applications, including:
- Reformers, HDS, HDT, HDC units
- Alkylation units
- Depropanizer/debutanizer columns and bottoms
- Texas Towers, vertical combined feed effluent exchangers
- Cleaning and fouling prevention of compressors
