## What is Costimator?

• This software evaluates the Purchased Cost and the Bare Module Cost for any process equipment in 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. 
• All affecting parameters, i.e. type, capacity, pressure, temperature, materials of construction, and inflation are taken into account. 
• Thanks to incorporating average values of published cost data, the accuracy of cost estimation is at a high level of ±12%. 
• All the 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, are included. 
• 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).
