Aspen EDR Integration with Aspen HYSYS The following new features and enhancements were added in release V8.0: Button on HYSYS Exchanger to switch streams between shell side and tube side Improved HYSYS Exchanger forms – to clarify model selection New “Rigorous Shell & Tube Auto-sizing” work flow New “Rigorous Shell & Tube Interactive-sizing” work flow New “Rigorous Air Cooler Auto-sizing” work flow New “Rigorous Air Cooler Exchanger Interactive-sizing” work flow Access to full Aspen Shell & Tube user Interface within HYSYS Access to full Aspen Air Cooled user interface within HYSYS
Aspen Shell & Tube Exchanger The following new features and enhancements were added in release V8.0: Console, giving an immediate overview of key inputs and results, both tabulated and graphical.
New input to help prescribe certain parameters in Design mode. New output of percent excess area, and ratio of actual to allowable pressure drop
Option of various types of finned tubes in X-shell Exchangers Corrected maximum ρ v2 (rho-V-squared) limit used for sizing tube side nozzles Options for handling accelerational pressure changes (particular relevance to low pressure exchanger modeling) The handling multiple shells with U-bends has been improved to correctly calculate the shell-side coefficient in all shells There is improved graphical output for X-shell exchangers in calculation details Feedwater Heater Simulation and Rating: For all customers with an Aspen Shell & Tube Exchanger license, the full capability of the Aspen FRAN program is now available
Aspen Shell & Tube Mechanical The following new features and enhancements were added in release V8.0: ASME code update for calendar year 2012
Changes based on code cases as applicable Includes BPVC VIII Div 1 and 2 (part 4) – 2011a (2012) The main release will continue to be 2011a in calendar 2012 Material properties updates as applicable Material prices were updated with a resulting average price increase of 2-1/2%
Added new tubesheet deflection calculation per mandatory requirement in UHX-13.4(d). Used new derivations per UHX philosophy Added additional flange types Added additional tube-to-tubesheet joint Added option to suppress nozzle reinforcement calculations when exempted by code rules. Added minimum baffle thickness as a function of shell side corrosion allowance Added type ‘g’ nozzles with self reinforcement in accordance to fig. UW-16.1 of ASME VIII Div 1 Added nozzle and reinforcing ring weld size information to the summary output. Added logic to select a larger anchor bolt diameter when the uplift force due to wind and/or seismic loads exceeds the bolt allowable load.
Aspen Air Cooled Exchanger The following new features and enhancements were added in release V8.0: Console, giving an immediate overview of key inputs and results, both tabulated and graphical.
New input to help prescribe certain parameters in Design mode. New output of percent excess area, and ratio of actual to allowable pressure drop
Option to specify the number of passes in design mode New warning on fans with low coverage of the bundle New warning for Designs using program default for allowable pressure drop.
Aspen Fired Heater The following new features and enhancements were added in release V8.0: Specification of main process stream duty as an alternative to specifying either inlet or outlet temperature. Specification of inlet enthalpy as an alternative to inlet temperature (for use when FiredHeater models are embedded in Aspen HYSYS or where process and property data are imported from Aspen HYSYS or Aspen Plus
Aspen Plate Exchanger The following new features and enhancements were added in release V8.0: Aspen Plate Fin Exchanger The following new features and enhancements were added in release V8.0: New stream details output for crossflow exchangers, showing how a range of parameters vary across the stream outlet. Values are also shown across each pass outlet, for multi-pass crossflow streams. The parameters include stream pressure changes, and an estimated flow rate variation, based on these changes. Fin databank file now recorded in program output Option to perform flow –balance calculation for crossflow exchanges, to determine the flow variation across the outlet width. Option to apply a multiplier to each process stream flowrate in a Simulation New thermosiphon option, to find the pressure head needed to drive a flow, in addition to option to find the flow rate, or to find the inlet resistance to balance a specified flowrate.
