Bob Mastropietro, VP Technology, Lodge Cottrell

Telephone: 908-304-2616

Mr. Mastropietro was contacted for information on the performance of
existing ESP at portland cement plants. He stated that existing ESP,
with any modifications, could probably reduce PM to about 0.01 – 0.02
gr/dscf. He thought they could be modified to reach levels as low as
0.002 – 0.004 by adding additional fields, but that it would be costly
and may be limited due to the additional space requirements.
