IE B042TECHNICAL ACTS OF 8 AND 30 JANUARY 2002
NF-611 and 2VU1-2.5 compressors: higher output, lower temperature — with no unit disassembly
The air compressors began filling their receivers faster, the hydrogen compressor reached a lower temperature. 22 % — output of the air compressors, receiver fill 4 min 10 s → 3 min 25 s; 10.5 % — operating temperature of the hydrogen compressor, 95 → 85 °C (2002).

Key results
| UNIT | SHOP AND CONDITION BEFORE TREATMENT | WHAT WAS MEASURED |
|---|---|---|
| Ammonia compressors NF-611 | Ammonia shop; heavy wear of the crank-and-connecting-rod mechanism and the cylinder-piston group, elevated oil consumption | Oil consumption in service |
| Air compressors 2VU1-2.5/13 | Compressor facility of the plant, regular service | Receiver fill time from 2 to 7 kgf/cm² |
| Hydrogen compressor, inv. No. 114541/9 | Hydrogenation Plant; operating temperature 95 °C | Operating temperature at a discharge pressure of 1.5 kgf/cm² |
Air compressors 2VU1-2.5/13 — delivery
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Receiver fill time from 2 to 7 kgf/cm² | 4 min 10 s | 3 min 25 s | 45 s |
Compressor output is inverse to the fill time: a reduction of 45 seconds corresponds to a 22 % gain in delivery.
Hydrogen compressor of the Hydrogenation Plant
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Operating temperature at a discharge pressure of 1.5 kgf/cm² | 95 °C | 85 °C | 10 °C |
The act takes the operating temperature as the principal indicator of this compressor's technical condition; the repeat measurement was taken after 42 hours of operation.
