Milestone Report No. 3 is a progress report. Rogers Engineering Co., Inc. has investigated what sites are best suited for consolidation of power generating units 1 through 12 for processing the noncondensable gases through the Stretford Process for H{sub 2}S abatement below 10% of the mass flow. The consolidation arrangement for the power generating units are Units 1 through 6 which produces 187 MWe power. Units 7-8 and 11 producing 212 MWe and Units 9-10 and 12 which also produces 212 MWe power. Site survey and selection for the Stretford units provided for a primary and alternative site for each consolidation. Each of these three groups of plants is associated with its Stretford Process Plant. The gas blowers located at each power plant to push the noncondensable gases through the stainless steel pipe network to the Stretford Process have been sized. When combining the new auxiliary load requirements of these blowers and the Stretford units it was determined that additional auxiliary transformer capacity is necessary. We are investigating additional alternatives with respect to the Stretford Process application. This data will be submitted in the Final Report, See Section 6.
