Chemical engineering plant cost index is used for finding the present cost of a particular chemical plant, if the cost of similar plant at some time in the past is known. The present cost of the plant = original cost × (index value at present/ index value at time original cost was obtained). The most major component of this cost index is____________________?
Correct answer: A. Fabricated equipment and machinery
- A. Fabricated equipment and machinery
- B. Process instruments and control
- C. Pumps and compressor
- D. Electrical equipments and material
Explanation
Fabricated equipment and machinery usually carry the largest weighting in a chemical plant cost index because major plant expenditure is concentrated in process equipment. Instruments, pumps and electrical materials have smaller separate weightings.
