Cost of running Utlilities 2

[Jigneshpadia2002]

Can Anyone give some idea about the cost of running Air, Steam and WFI in a mid size Biotech or Pharma plant?

What is the typical consumption of WFI, Air & Steam? Say in a company like Glaxo, Pfizer or Elilly!

No thumb rule for either of the things. That depends upon the type of product and production capacity. Utility cost has many factors to consider. For example, here in India, WFI is costing Rs0.75/liter, compressed air Rs 0.3 for cu.ft and steam Rs 0.5 per kg.

Typical analysis for WFI

1. Cost of purified water
2. Cost of steam
3. Cost of electricity
4. Man power cost
5. Cooling water/ chilled water cost
6. Initial investment spanned over life of the equipment (or upto the depreciation period)
7. Cost of maintenance

Typical analysis for compressed air

1. Cost of electricity
2. Cost of Cooling water
3. Cost of man power
4. Initial investment
5. Cost of maintenance

Typical analysis for steam

1. Cost of fuel
2. Cost of feed water
3. Cost of man power
4. Initial investment including fuel storage
5. Cost of maintenance

Quark had a deep cost analysis but I would add some on my own:

WFI
Cost of raw water;
Cost of sodium metabishulfide (or any other chemical system that you use to reduce chlorine);
Cost of instrument calibration (maybe Quark included in manpower cost. There is a lot of instruemntation in a PW skid);


For all of them don't forget the actual output rate (Kgs/steam produced, PW cubic meter and, Compressed air cubic meter)
