Nuona Pignone Firenze

1. General and Design

●      Equipment: 2 gas compressor units.

●      Construction technology: Reciprocating or screw type, complying with API standards.

●      Process fluid: Natural gas (origin: Bermeo, Serrablo, Algeria, or mixtures).

●      Operating lifespan:  100,000 hours of continuous operation.

●      Maintenance cycle: approx 8,000 hours of uninterrupted operation between shutdowns.

2. Thermodynamic and Operational Parameters

●      Flow rate: 1.00~nm3/s per unit.

●      Suction pressure: 11.0 barg.

●      Discharge pressure: 22.5 barg.

●      Suction temperature: 5 Centigrades .

●      Maximum discharge temperature: +120 Centigrades.

●      Pressure pulsation limit: +0.20 bar to the turbine.

●      Acoustic emission: 85 dB (A) at a 1-meter distance.

3. Mechanical Specifications and Motorization

●      Cylinders: Minimum design pressure of 25 bar, with water-cooled jackets.

●      Main motor: 380 V electric motor, explosion-proof.

+1

●      Installed power: Minimum 1.1x the compressor's maximum demand.

●      Transmission: Direct drive preferred, or V-belt with a  1.5 service factor.

4. Auxiliary Systems and Control

●      Capacity control: Remote unloading valve (0% / 50% / 100%).

●      By-pass regulation: Independent by-pass system for each unit, allowing zero-flow operation.

●      Lubrication system: Integrated forced-feed. Includes a main shaft-driven pump (100%) and an auxiliary AC electric pump (100%).

●      Oil filtration: Duplex type filter with continuous transfer valve.

●      Exhaust gas purity: Oil-free piston operation preferred, with a maximum oil content of < 1 ppm.
