Process Equipment Cost By Size Exponent

Process Equipment Cost Estimating by Ratio and Proportion

An analysis of the cost of individual pieces of equipment shows that the size factor’s exponent will vary from 0.3 to unity, but the average is very near to 0.6, thus the name for the rule of thumb. If a higher degree of sophistication is sought, Table 1 below can be used. It lists the value of a size exponent for various types of process ...

The Cost-to-Capacity Method and Scale Factors - …

More specifically, cost is a function of size raised to an exponent or scale factor [2]. The governing equation is as follows: The raised scale factor in Equation 1 above accounts for the nonlinear relationship and introduces the concept of economies of scale where, as a facility becomes larger, the incremental cost is reduced for each additional unit of capacity [3].

Economies of scale - Wikipedia

Overall costs of capital projects are known to be subject to economies of scale. A crude estimate is that if the capital cost for a given sized piece of equipment is known, changing the size will change the capital cost by the 0.6 power of the capacity ratio (the point six to the power rule).

Sampling provides qualitative and quantitative information concerning a process or product. Although desirable, 100% sampling is rarely possible due to costs, time, or destructive testing methods. Thus, it is important to develop a sampling plan that balances the information obtained from the tests with the costs and time to conduct the test.
