Metal piston skirts instead of polymer piston rings allow high discharge temperatures if required by the process „Hot spots“ „Hot spots“ due to friction can lead to polymerisation or melt particles carried over in the gas Long service life since piston move in cylinders without friction, therefor not subject to continuous wear CTL2_Laby® General Presentation Customer Training Page 12 Comparison between Ring and Labyrinth Piston Piston with Plastic Rings Pollution due to abrasives from plastic rings carried in gas stream Piston with Labyrinth Compressed gas is delivered with unchaged purity, risk of carry over of abrasives from piston, rider or packing rings is eliminated Contaminated gases Small particles carried in the gas stream increase piston ring wear In all cases where the process gas is contaminated, the labyrinth piston will not wear Cylinder liners Piston and rider rings sliding along the cylinder wall require cyliner liners with superfinished surface Cylinder liners are not required Lifetime Continuous wear due to dry running piston rings and therefore reduced lifetime and high maintenance costs (more frequent shutdowns) Long service life since piston move in cylinders without friction, therefor not subject to continuous wear CTL2_Laby® General Presentation Customer Training Page 13 DESIGN LABY® COMPRESSORS CTL2_Laby® General Presentation Customer Training Page 14 Laby® Compressor Design Open type Distance piece: open Crankcase: open Open type purged for toxic and corrosive gases closed open Gastight type for atm. or slightly elevated suction pressure closed mechanical seal Closed type with pressurized crankcase closed mechanical seal CTL2_Laby® General Presentation Customer Training Page 15 Key to Type Designation CTL2_Laby® General Presentation Customer Training Page 16 REFERENCES CTL2_Laby® General Presentation Customer Training Page 17 Laby® Compressor Type 4D300-3G Steel Plant Customer: Nippon Sanso, Toyo for Don Kuk Steel Mill, Inchon, South Korea Gas Suction volume Suction temperature Suction pressure Discharge pressure Shaft power Speed O2 4’612 m3/h 17 °C 1.40 bar a 25.90 bar a 873 kW 394 rpm CTL2_Laby® General Presentation Customer Training Page 18 Laby® Compressor Type 4D300-3L Air Separation Customer: AGA Gas Rissnelden for Stenungsund Plant, Sweden Gas Suction volume Suction temperature Suction pressure Discharge pressure Shaft power Speed O2 5’340 m3/h 10 °C 1.20 bar a 46.00 bar a 1’030 kW 420 rpm CTL2_Laby® General Presentation Customer Training Page 19 Laby® Compressor Type 4D300-3G Petrochemical Plant Customer: Air Products & Chemical, Allentown for Samsung, Daesan, South Korea Gas Suction volume Suction temperature Suction pressure Discharge pressure Shaft power Speed O2 4’710 m3/h 16 °C 1.92 bar a 28.80 bar a 1’137 kW 394 rpm CTL2_Laby® General Presentation Customer Training Page 20 Laby® Compressor Type 4D225-2E BOG Plant Customer: Alliance Bechtel Lind (ABL) for Abu Dhabi Polymers Gas C3H8 Suction volume Suction temperature Suction pressure Discharge pressure Shaft power Speed 1’134 m3/h -23 °C 1.75 bar a 6.55 bar a 334 kW 370 rpm CTL2_Laby® General Presentation Customer Training Page 21 Laby® Compressor Type 4DE250-4D lldPE Plant Customer: Aker Kvaerner for EVAL , Zwijndrecht, Netherlands Gas C2H4 Suction volume Suction temperature Suction pressure Discharge pressure Shaft power Speed 2’300 m3/h 40 °C 1.16 bar a 80.00 bar a 1’270 kW 424 rpm CTL2_Laby® General Presentation Customer Training Page 22 Laby® Compressor Type 4D300-2B Customer: PP-Plant M.W.
