Earlier preliminary cost estimates for a new PVC plant have been refined based on information obtained during the visit with Conoco in Oklahoma City July 20, 1972. A plant of 240 >21 Ib/yr capacity, or double Conoco's plant size, would require a capital investment of about $13 >21 before license fee for a Pasadena location. This cost is based on the same design concepts as used in Conoco's plant but provides for considerably more product storage, warehousing, and packaging facilities. Conversion cost of monomer in such a plant would be about 1.4c/lb. Capital cost would be essentially the same as for a plant using the Shin-Etsu process, but operating costs should be slightly lower because of elimination of refrigerated cooling and colonized water in the Conoco process.
^rscussion
Capital costs for a 240 121 lb/yr PVC plant (3 reactors) using Conoco technology are developed in Tables I - III. The costs of major equipment listed in Table I are essentially the same as those reviewed in Piscataway July 14, 1972. These major equipment costs are developed into a factored plant capital cost in Table II for a Pasacena location. The construction factors leading to the $12.9 MM cost are based on open shop labor rates which currently average about $5,75 per hour. Tno estimate includes 15-15,000 cu. ft. silos (or about 10 day's storage.) and a warehouse for aoout two week's storage of 20% of the plant output.
Taole III develops an alternate capital cost estimate. In this case the Conoco assessment data showing $3,630 M battery limits cost for a 120 >21 lb/yr plant was scaled up using a 0.95 scale factor. This produced a battery limits direct cost aoout 10% lower than developed from our own itemized equipment estimate. Using the same offsites estimate as in Table 1 gives a total plant cost of about $900 M less than the itemized estimate.
-* conversion cost or 1.32q/lb is developed in Taole rV. This cost includes a staff of 13 operators, 4 shift supervisors and a unit supervisor. It also includes double the maintenance manpower shown by Conoco for their 120 >21 lo plant.
T^ore V tabulates the main deletions of major equipment from the nreviously assumed design based on Conoco's successful operation without these items of equipment. *-le items which migut still be questionable are holding bins ($260 >1 installed), bacic-up generator ($4j.O M installed), and demineralized water units and tank ($352 >1
installed), keeping tnese items in the plant would therefore increase total cost by about $1 MM.

A rough comparison or the S'nin-btsu process wiLh Conoco's indicates that Lucre is probably little difference in capital requirements. Table VI summarizes the main items of equipment in which the processes differ. The Shin-btsu reactors arc appreciably cheaper on an installed basis, but this advantage is approximately offset by elimination in the Conoco process of chilled water cooling, jacket water pumps, gas holder, distillation, and use of demineralized water.
