Erol Seker, used UniSim Design and UniSim Dynamics to create a preliminary conceptual design and simulation of the production of bio-based ethylene from the marine microalgae of Nannochloropsis oculata.
Ozgun Deliismail and Okan Akin, under the supervision of Associate Professor Dr. They have been named the winners of Honeywell Process Solutions’ (HPS) annual UniSim® Design Challenge.
Works With.Two students from the Izmir Institute of Technology have used Honeywell’s simulation software to demonstrate how to produce petrochemicals from algae. For single-zone modeling, use Xfh ® Ultra, our general-purpose fired heater program. Additional combustion and convection section modules allow evaluation of a complete process fired heater. X fh uses a Hottel zoning method to calculate localized radiant and process side performance. Simulate the performance of cylindrical and box heaters. X vib considers fluidelastic instability and vortex shedding mechanisms for both straight tubes and U-tubes.
XvibĬalculate flow-induced vibration for a tube in a shell-and-tube exchanger using a rigorous finite element based algorithm. X spe models cocurrent and countercurrent spiral flow (Type I exchangers). Rate and simulate single-phase spiral plate exchangers using an incremental model with HTRI-validated heat transfer and pressure drop correlations. X phe contains a port maldistribution model that calculates the flow through each plate channel. Rate, simulate, and design plate-and-frame exchangers using user-defined plate types or plates selected from an internal manufacturers’ databank. X pfe contains graphical layout tools that make even complex stream arrangements easy to create. Simulate and design multi-stream axial and crossflow plate-fin exchangers using an incremental model with research-based heat transfer and pressure drop correlations. X ist supports all standard TEMA exchanger types, and includes integrated tools for flow-induced vibration calculations and tube layout design. Rate, simulate, and design virtually any type of shell-and-tube exchanger, including kettles, hairpins, thermosiphons, reflux condensers, and falling film evaporators. X ace includes vendor fan selection calculations and options to simulate the effect of flow and temperature maldistribution. Rate, simulate, and design air coolers and economizers, including natural draft (fans off) and forced draft conditions.
Exchanger Optimizer, installed separately, can be launched from within X changer Suite to generate comprehensive cost assessments and validate designs based on ASME code calculations.Import of input files from HTFS ® (shell-and-tube and plate-fin exchangers), Honeywell’s UniSim ® Heat Exchangers (shell-and-tube and plate-fin exchangers), and Aspen Exchanger Design & Rating (shell-and-tube and air-cooled exchangers) allow modeling within X changer Suite.
