Abstract
The load on the starting steam turbine or motor which drives the power recovery string of an FCC process is reduced on the order of 15% by increasing the specific volume of the air compressed by a fixed volume compressor in the string. The specific volume of the ambient air is increased by returning a portion of the compressed and thereby heated air to the inlet of the compressor in amounts sufficient to raise the temperature of the inlet air about 75.degree. F., or more.
