Sun Pharmaceuticals, India
In brief. Heat from three Deutz engines is split between two Thermax chillers and a steam boiler; process cooling is about 2,500 kW.
At the Sun Pharmaceuticals plant, three 1.4 MW engines run on gas. The exhaust and jacket water drive two Thermax absorption chillers, and a heat recovery steam generator produces steam separately. Total cooling is about 2,500 kW of process cooling.
What does the project consist of?
| Parameter | Value |
|---|---|
| Industry | Pharmaceuticals |
| Engines | 3 Deutz (MWM) engines, 1.4 MW each |
| Fuel | Natural gas |
| Heat for the chiller | Exhaust at 527 and 478 °C, jacket water at 90 °C, plus a heat recovery steam generator producing 2,917 kg of steam per hour |
| Chiller and cooling | 2 chillers: 1,652 kW (470 TR) and 844 kW (240 TR) |
| What the cooling is for | Process cooling |
Why is this example useful for a Russian site?
Three 1.4 MW engines give 2,496 kW of cooling, about 0.6 kW per kW of electricity: part of the exhaust goes to the boiler producing 2,917 kg of steam per hour. That is why a plant first determines how much steam it needs, and only then calculates how much heat is left for cooling. More: trigeneration for pharmaceuticals.
How does this kind of scheme work?
The heat recovery steam generator produces steam. In the diagram, steam also goes to a steam-fired chiller; here the cooling comes from chillers running on exhaust and jacket water, and the steam goes to the plant.
