Auto Water Draw Hysys

The hysys software can be found using the following path from the windows start menu.

Auto water draw hysys. Radio button in 2 3 phase of column try auto water draws again. As with the dewpoints water content can be calculated in hysys using the gas properties extension or by adding the corresponding gas property correlation to a hysys stream. This tip is the follow up of the previous tips april and may 2016 1 2 which investigated the benefits of having a water draw and its optimum location in a condensate stabilizer column see chapter 16 of reference 3 it will simulate the performance of an operating condensate stabilizer column equipped with side water draw tray to remove liquid water. Solve large scale models quickly through equation oriented solver technology.

Boost profitability by closing the gap between planning and actual operations through aspen hysys s v11 release. The levulinic esters production process was simulated using hysys v8 8 software. However i am unable to control the amount of water to be drawn it is done by hysys automatically. Once hysys is installed on your computer the next step is to open the software.

Generated table these three variables can be used to draw a txy diagram and a xy diagram using the excel program. Optimize integrated cdu and preheat trains operations leveraging real time. Hope this option is available in hysys i am using honeywell s unisim design. Not sure about its availability in hysys.

When this function is turned on i am able to add a water draw stream in the column environment. Flash zone 1st draw 3 7 30 1 2 1st draw 2nd draw 7 10 45 50 3 5 2nd draw 3rd draw 7 10 50 55 3 5 top draw reflux 10 12 60 70 6 8 vacuum column g o. In order to maximize water removal for higher feed water rate the tip moved the side water draw from tray 7 to 8. Update refinery planning models with streamlined workflows using process simulation solutions calibrated to plant operations.

Turn on the auto water draw function of the distillation tower. The hysys tabular results for the raoult s law case study are shown as follows. The thermodynamic properties and kinetic data are obtained from open literature and used in the aspen hysys model. The gas properties extension calculates the water content in two sets of units lb mmscf and mg m3 while the stream correlation only calculates the water content in mg m3.

Start all programs aspentech aspen hysys aspen hysys while you may have more or less programs in the aspen hysys folder the only one needed to model a distillation tower is the main aspen hysys program. Table 3 clearly indicates that water draw at tray 7 give higher water recovery percent for lower feed water rates up to 1200 lbmole d 545 kmol d and water draw at tray 8 give higher water recovery for higher feed water rate.
