In May 2008 Burckhardt Compression received an order from LyondellBasell in Germany to replace the temperature detecting system AMOT on their hyper compressor K10 at the Aubette plant in France, which has been in operation since 1999.
LyondellBasell decided to equip the hyper compressor with the PROGNOST®-NT monitoring and diagnostic system. As a further improvement, Burckhardt Compression received the order to replace the existing temperature detecting system AMOT with a new system for real-time monitoring of bearing temperature on non-stationary moving parts, called Sentry. In the short time of six days, Burckhardt Compression’s team accomplished the replacement of the system, including the installation of the new temperature sensors.
As an original equipment manufacturer (OEM) with more than 160 years of experience in the design, manufacture and service of reciprocating compressors, Burckhardt Compression has a dedicated team of specialists and technical competence for retrofits, engineering services, revamps and overhauls. Burckhardt Compression is the market leader for hyper compressors with a discharge pressure up to 3,500bar.
Compared with the old temperature detection system, the new system continuously measures the bearing temperature and gives out one value per revolution on non-stationary moving parts, which is only possible due to the wireless sensor technology. The operators receive real-time temperature information, trend lines and diagnostics. Shutdowns can be scheduled and incorrect shutdowns will be avoided. The risk of unforeseeable repair costs will be minimised.
Hyper compressors are high-pressure reciprocating compressors for low-density polyethylene plants up to 3,500bar (50,000psi). It excels with a long lifetime and safety features thanks to its unique design and Burckhardt Compression’s worldwide one-stop service.
