Table F-2 summarizes these costs for each of the two polymers. ThL annual costs were adjusted as follows: o Capital-related costs, C1, I l were adjusted using the equation I (~^)0*~ where: VI = total initial volnme of flow from model process section and V, = adjusted flow rate. o Operating-related costs, Cp, were adjusted using the equa!tion Capital-related costs included capital recovery, maintenance,' taxes, insurance and administration charges. operati ng-related cdsts included utilities (e.g., natural gas, steam, electricity). operating labor was assumed to be constant. ~ I I I1 I 1 I Fourth. As flow rates vary, the size of the control device rdqui red will also vary. No matter how small the flow, however, there are' 1 certain minimum size control devices avail able; thus, control device I costs do not approach zero as flows become very small. In addition, 1 some utility requirements, such as natural gas purge rates, may be constant, or even increase as flow rates become increasi ngly smal ier. Finally, a different control device design may be more cost effective as flow rates change. For example, as flow rates approach 1.46 sCfm (70°F), a change in flare design was assumed to occur where a flahe with a fluidic seal was used for flows less than 1.46 scfm. ~ablkF-3 summarizes the basic minimum costs associated with the various cothrol I devices at flow rates that affect design criteria. Fifth. Using the above information and procedures, the following basic equation was solved for Vx for each process section: whe \ 11 and $3,000/~g re: C; = the difference between the capital-related costs of the control device control ling V1 and the capital -related costs of the control device controlling V2.
