This is a 8 throw horizontal compressor size 500, NEUMAN & ESSER’s biggest. It is used for two hydrogen mix processes. Looking on its dimensions – API 618 rod load 1,700 kN, compressor power 17,000 hp, motor power 20,000 hp, oil volume some 4,100 l and a overall compressor weight of 250 t – you can call it huge.
In the first process it has 3 stages, cylinder diameters 1,220 – 980 – 660 mm and piston weights of 1,8 – 1,3 – 1,0 tons. The second process is compressed in two stages with cylinder diameters 1,220 – 1,060 mm and piston weights of 1.8 t – 1.4 t.
