Question

3) Using an order of magnitude method (Hill), estimate the TCI in year 2006 dollars for a grass-roots plant with 100,000-lb annual production using an order-of-magnitude method based on a 10,000-lb annual production. The plant contains three 1200-ft/min centrifugal fans, five 1500-ft/min centrifugal blowers, seven 100-ft' centrifugal separators, and two 100-ft shell-and-tube heat exchangers. You may assume all materials are carbon steel, the materials handled are primarily solid, and that this plant construction is done fully outdoors. Also assume the design pressure is 65 psia*. There are no compressors or high pressure reactors Hint: Begin by determining the total bare module costs for the pieces of equipment. This may be simplified using Hill's Step 2 Since they are all made of carbon steel, you may approximate the total bare module cost, CM for the seventeen pieces of equipment: TBM
