The ENI refinery in Sannazzaro De Burgondi, Italy, operates a Finder centrifugal pump in its gasification unit. The pump is sealed by EagleBurgmann HRKS4-DF/58 mechanical seals.
Operating conditions: p = 16.08 ... 19.93 bar (233 ... 289 PSI); t = 238 °C ... 263 °C (460 °F ... 505 °F); n = 2,955 min-1; d1 = 80 mm (3.15"). Medium: carbon slurry.
De-ethanizer pump in a LPG fractionation unit of the ENOC refinery, U.A.E., equipped with an unpressurized dual EagleBurgmann sealing system according to API 682. Configuration: 2CW-CS, piping plans 14 and 76.
Operating conditions: p = 36 ... 39 bar (522 ... 566 PSI); t = 1 °C ... 43 °C (34 °F ... 109 °F); n = 2,933 min-1. Medium: LPG. The MTBF has improved drastically since installation.
The two-stage screw compressor (Aerzen VR0825) used to compress coking oven gas in a coking plant is one of the biggest ever built. It is sealed with an EagleBurgmann type HSH2/215.
A GE-Thermodyn compressor - operated in the isomerization unit of the Tüpras Kirikkale refinery in Turkey - is safely sealed with EagleBurgmann dry gas seals type DGS9/123.
Operating conditions: p = 12.6 bar (182 PSI); t = 38 °C ... 150 °C (181 °F ... 302 °F); n = 12,915 min-1; d1 = 103 mm (5.06"). Medium: mixture of hydrocarbons.
Coking oven gas compressor (Mannesmann Demag) at Wintershall AG, Lingen. Originally equipped with labyrinth seals, the turbine-driven single-shaft radial compressor has been converted to EagleBurgmann dual DGS seals and a buffer gas supply system.
Operating conditions: p = 5.6 barg (81 PSIG); n = 12,800 min-1; d1 = 134.8 mm (5.3"). Medium: gas with H2S-content.
For a MAN Turbo compressor at Shell Godorf, Germany, EagleBurgmann has supplied a DGS20/113 dry gas seal together with a SMS seal management system. The compressor is operated in the gas processing section of the plant.
Operating conditions: p = 30 bar (435 PSI); t = -20 °C ... 180 °C (-4 °F ... 356 °F); n = 9,811 min-1; d1 = 100 mm (3.94"). Medium: gas.
