Pain points
A simple switch from gas to direct electric heat can raise operating cost if process temperature levels are not redesigned.
The project must include electrical capacity, load profile and integration with production.
Tradeoffs
Heat pumps offer efficiency at moderate temperatures. MVR is powerful for evaporation. Electric boilers are useful but consume one unit of electricity per unit of heat. Hybrid systems reduce risk during transition.
Engineering FAQs
What should be modeled first?
Temperature levels, hourly heat demand, grid capacity, energy prices, CO2 factors and production constraints.
