Successful Revamp of a Non-Burckhardt Compression Primary
Share:
Burckhardt Compression delivered two cylinders for an existing Sumy primary compressor
for a LDPE plant in Tomsk, Siberia.
In July 2006, Burckhardt Compression received an order from the LDPE plant Neftechim in Tomsk,
Siberia. It included the replacement of two first stage cylinders of a 4 crank Sumy primary
compressor with Burckhardt Compression cylinders as well as their on-site installation. Since July
2007, when the cylinders were installed, the compressor has run absolutely trouble free. Thanks to
the revamp the plant productivity increased from 170'000 tons-per-year to 220'000 tons-per-year
LDPE.
As an OEM (original equipment manufacturer) with over 160 years of experience in the design,
manufacture and service of reciprocating compressors, Burckhardt Compression has the
specialists and technical competence for revamps, overhauls, engineering services and repairs for
other brand compressors (OBC). Burckhardt Compression is the market leader for hyper
compressors with a discharge pressure up to 3500 bar.
The three stage LDPE compressor was manufactured by Sumy in the year 1992 in the Ukraine.
During the 13 years of compressor operation various downtimes occurred and the required volume
was never achieved. Results of a comprehensive in-house feasibility and engineering study of the
process, the rod load and the required lifetime have led to the decision to replace the Sumy
cylinders with cylinders of Burckhardt Compression design with state-of-the-art features. The
additional pulsation and vibration studies confirmed that the replacement can be done. Neftechim
decided in favor of Burckhardt Compression due to its broad experience and the low lifecycle cost
of its products.
Productivity and availability improvements of existing reciprocating compressors or changing
compression requirements often call for revamps or up-ratings. With Burckhardt Compression's in
house state-of-the-art sizing and finite element analysis tools professional specialists can model
and calculate any existing reciprocating compressor.
