Can a scrubber be energy efficient?

Question

i am talking bout the scrubber used as the pollution controlled device.

Answer 1

It's all relative. If the scrubber can be engineered to be run using waste heat, cooling/filtering water flow, etc, or co-powered using small amounts of existing energy inputs, than it could be considered efficient. If the operating costs outweigh the benefits, than it is not efficient.

This is a good argument for tax incentives for the utilization of green technology.

Answer 2

It depends on how you define energy efficient. Any scrubbing is an extra that is not needed for whatever is being scrubbed to work, so in that sense it is just a waste. Scrubbing the smoke from a coal fired power plant can only reduce the energy efficiency of the plant for example. The best scrubber would use zero energy and have no effect at all on the energy efficiency of the power plant.

If you mean one scrubber removing the same pollution as another while using less energy, then that one is more energy efficient than the other. Or less wasteful. It depends on how you look at it.
