Follow-Up Order for Major LDPE Compressor Overhaul

3. Dezember 2019

SABIC, a global leader in diversified chemicals, operates three LDPE lines at their plant in Geleen, The Netherlands. After the successful compressor overhaul of one line in 2017, Burckhardt Compression was awarded another major overhaul order for the second line. The booster/primary compressor (Ingersoll Rand) and the Hyper Compressor (Burckhardt Compression) have been in operation for over 40 years. Thanks to the detailed planning we were able to manage the scope, including a challeng­ing foundation repair during the turnaround, according to schedule.

“To overhaul both compressors at the same time while repairing the foundation for the booster-primary was a  hallenge. With Burckhardt Compression we had a partner that was working hand in hand with us and who acted mostly proactive on unanticipated situations. We finished the job on schedule and kept the plant shutdown time to a minimum.”
