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 equipment.

3. For capital cost estimation: FOB equipment cost increases with sizen where n is usually 0.6 to 0.7. When n = 1 there is no capital cost advantage to building larger; increase size or capacity by duplicating equipment. 4. For capital cost estimates: (FOB q L+M* ) + installed instruments + buildings required within the battery limits = L+M cost.

where x is the power-sizing exponent, costs of A and B are at the same point in time (same dollar basis), and size or capacity is in the same physical units for both A and B.' The power-sizing exponent (x) can be 1.0(indicating a linear cost-versus-size/capacity relationship) or greater than 1.0 (indicating diseconomies of scale), but it is usually less than 1.0 (indicating economies of scale).

5 Types of Cost Estimates - Cost Engineering

Equipment factored estimating. An equipment factored estimate is produced by taking the cost of individual types of process equipment, and multiplying it by an "installation factor" to arrive at the total costs. In practice, this has proven to be quite a useful method since a substantial part of total project costs are made up of equipment.

Cost estimating for chemical engineering plant

Equipment sizing: Before the cost of equipment can be estimated its size must be determined. Similarly, the utilities requirements must be calculated. N ote that HYSYS/UniSim uses inappropriate default values when the units are first entered, e.g. tower diameter and heat exchanger area. Do not use these default values for cost estimation.

Cost Allocation – Meaning, Importance, Process

Cost Allocation or cost assignment is the process of identifying and assigning costs to the various cost objects. These cost objects could be those for which the company needs to find out the cost separately. A few examples of cost objects can be a product, customer, project, department, and so on. The need for cost allocation arises because some ...
