Estimating Annualized Cost, CA
{"Image DocumentName": "Estimating Annualized Cost, CA", "Image ImageDescription": "For each separation, CA is estimated assuming 99 mol % recovery of light key in distillate and 99 mol % recovery of heavy key in bottoms. The following steps are followed: Set distillate and bottoms column pressures using. Estimate number of stages and reflux ratio by FUG method (e.g., using HYSYS.Plant Shortcut Column ). Select tray spacing (typically 2 ft.) and calculate column height, H. Compute tower diameter, D (using Fair correlation for flooding velocity, or HYSYS Tray Sizing Utility). Estimate installed cost of tower (see Unit 6 and Chapter 9). Size and cost ancillary equipment (condenser, reboiler, reflux drum). Sum total capital investment, CTCI. Compute annual cost of heating and cooling utilities (COS). Compute CA assuming ROI (typically r = 0.2). CA = COS + r CTCI. DESIGN AND ANALYSIS II - (c) Daniel R.
