This application estimates both the Purchased Cost and the Bare Module Cost of process equipment for any given year from 1957 to present. For each piece of equipment, there are three interactive columns which provide a convenient environment for copy-paste, comparison, and sensitivity analysis. The calculation core is adopted from Turton et al. (2018) who reviewed and updated the modular technique and cost data proposed by Guthrie (1974) and Ulrich (1984). All affecting parameters, i.e. type, capacity, pressure, temperature, materials of construction, and inflation are taken into account for equipment cost estimation. Thanks to incorporating average values of published cost data, the accuracy of cost estimation is at a high level of ±12%. This application covers all major process equipment, i.e. Blenders, Centrifuges, Compressors, Columns, Conveyors, Crystallizers, Drives for Pumps and Compressors, Dryers, Dust Collectors, Evaporators, Fans, Filters, Heaters, Heat Exchangers, Mixers, Turbines, Pumps, Reactors, Screens, Storage Tanks, Vaporizers, and Vessels.
