Published by Amos Peters Modified over 3 years ago. Title slide [from Title Slide master] The title slide is available as a Title Master and the background and graphic elements are fixed. Text is editable for the slide heading and presentation details but the small compliance text exists in editable form only on the Title Master itself.
This type area should be used only for the purposes of compliance text and should not be replaced by other content.
PB-SSE11 DYNSIM and Dynamic Simulation for Process Relief Calculations
Font, type size and colours are fixed for the Title Master style and should not be modified. Footer details Footer detail appear in the bottom-left corner of the slide and appear in fixed positions and order. Customers could potentially re-script install for internal deployment. The SimExecutive checks for a valid license and returns it after finding one. This feature has been implemented for all products, which use the SimExecutive framework i.
No schema evolution required for migrating existing simulations. Unrealistic pressure response when vapor exists, for example hydrocracker, shift reactor,…, etc.
More realistic temperature response on fluid and catalyst phases. Pressure drop result may be unrealistic Rigorous pressure drop calculation Including catalyst effect, and fluid physical properties density, viscosity, molecular weight, etc.
Turpin and Huntington Vapor-liquid Cynsim phase system Upward and downward flows. Strongly impact pressure response, pressure drop, and liquid holdup. Stream Receive calculates how sensitive downstream pressure is to upstream flow Explanation about the test case — There are four parallel trains in the simulation to compare different modes of stream data transfer: First train – Entire network in the same engine.
This dynsi the base case for comparison. Second train — Network split into two engines and connected using explicit cross referencing using Source models.

Open the second flowsheet to show the split network. Third train — Network split into two engines and dunsim using Stream Send-Stream Receive pair using local sensitivities. Fourth train — Network split into two engines and connected using Stream Send-Stream Receive pair using network sensitivities. Steady state run — Load the simulation and load IC 2.
There are total of 7 points in each of these trends. As the name of these points indicate, they represent mass flow and pressure on the two sides of the network. The seventh point belongs to the single engine case.
There are two things that need to be compared: Comparison of mass flow and pressure on the two sides of dynsimm network. The closer the match, the better it is. Comparison of values with the single engine case which is the seventh point on each of the trends. The closer the match with the single engine case, better it is. At steady state, everything is perfectly fine in this case.
This will open the corresponding Valve in the other three networks. Keep the two trends mentioned above open. Run the simulation for a few seconds and pause it. Now do the same comparison as mentioned above. Here the Stream Send and Stream Receive has a much better mass balance and then other cases.
You will have to notice it very carefully as the difference in different modes is apparent only for a few time steps. However, Stream Send and Stream Receive with local sensitivities will be seen to be quite away from the single engine case very clearly. Ignores the impact of other network elements on the sensitivity calculations. As a result of this, the sensitivities at times are quite a bit off compared to the actual sensitivities. At times, this results in following two issues: Mass imbalance and pressure inequalities across the network.
Flows and pressures quite different compared to single network in a single engine. Valid host not found. Mapped to SimExec host. Integrator provides the integration of a process variable. XY plots display in user configured curve bases.
The default value of efficiency is 1. Leaving Losses are associated with last stage in a multi-stage turbine operation especially in low pressure turbines. The losses are considered to be independent of flow or turbine speed conditions Built-in leaving losses curve There is a built in curve which is based on a typical GE LP turbine. Used in calculation of Work of Expansion as shown below: Calculation of differential axial expansion between rotor and casing.
Metal casing model needs to be connected to equipment through heat streams for which metal wall temperature is required. Metal casing model as rotor: There is no heat loss to ambient. External heat input is not allowed. The data can be easily accessed by any pipe model. Ease of configuration and maintenance! Key Benefits Well recognized in the upstream industry.
Applies to pipes of all inclination angles. Key Benefits Useful for flare systems. Sudden temperature changes due to high velocity changes inside the pipe are accounted for more accurately. Simplified Ejector design based on performance curves.
Can be used to model steam Ejector. Suction side flow is determined by the performance curves. The features in this version include: Whether back track replays are possible or not Simulation time at which backtrack is saved.
