ProSimPlus Standard 3.7.11

• Reactors unit operations >> New functionalities have been added to the plug flow reactor in order to display the reaction rates profiles by reaction and by compound depending on the length of the equipment.These new profiles are available in the “Profiles” tab of the unit operation.
• A new example has been created. After installing the new version, the examples are available using one of the following two methods:Examples are automatically installed with the new version of the tool in the “Examples” folder of which a shortcut is installed on the desktop of your computer and accessible through the following path “..\ProSim\Examples\ProSimPlus Standard \”The examples are also accessible via the ProSim support internet website with your username and password (https://www.prosim.net/en/log-in/)

  The new example is: “HIGH TEMPERATURE HEAT PUMP”

• This example simulates a high temperature (HT) heat pump (HP) working with R1233zd. Temperature needs greater than 150°C can be obtained with high temperature heat pumps.This type of technology is ready to be implemented in the industry, and it provides interesting options for the decarbonization of processes.

  This example is based on the data from a European project “PUSH2HEAT”. This project studied a paper factory “Cartiera di Guarcino” located in Italy.

  Different needs in steam at different pressure levels are required by the factory. Different units produce steam: 3 cogeneration engines, 2 gas boilers and a high temperature heat pump.

• The process diagram is as follows: the steam flows are presented in orange/brown and the heat pump is presented in green. The COP of this heat pump is 3.3.The ProSimPlus file and the documentation is supplied with the example.

ProSimPlus HNO3 3.7.11

• The computational time has been improved in two of the specific modules of ProSimPlusHNO3: the packing oxido-absorption column (with 1 or 2 beds) and in the oxidation reactor.
  In the case of the packing oxido-absorption column, the order of calculation of the oxidation volumes in the global resolution of the module has been reviewed.In the case of the oxidation reactor in the differential calculation mode, the calculation progress has been removed if no intermediate prints are requested. Moreover, in case of intermediate prints, instead of displaying the progress for each step, this information is only printed every 20 steps as well at the end of the calculation (still to improve the calculation time).
• New functionalities have been added to the plug flow reactor in order to display the reaction rates profiles by reaction and by compound depending on the length of the equipment.These new profiles are available in the “Profiles” tab of the unit operation.

ProSec 3.7.11

• The new method for taking into account the pressure on the enthalpy curves to simulate thermosiphons (non-monotonic temperature profile) is now available: in CWT (Common Wall Temperature) resolution and for streams using tabulated thermodynamics in ProSec Reaction.
• It is now possible to choose the model used to calculate vapor-liquid densities. This parameter is used, in particular, in the calculation of gravity pressure drops. This is especially important for the simulation of thermosiphons. It is possible to choose between a proprietary slip model and a homogeneous model. By default, all new simulations will use the proprietary slip model. In previous versions, reactive simulations used the homogeneous model. The same model is used for all fluids. If a fixed-bed catalyst is present, the homogeneous model will be used for all fluids.
• The mean void ratio model can be edited via the “mean void ratio model” menu in the “Others” tab of the “Numerical Parameters”.
• A new Getting Started document is now available. After installing the new version, the ProSec Getting Started are available using one of the following two methods:Documents are automatically installed with the new version of the tool in the “Getting Started” folder of which a shortcut is installed on the desktop of your computer and accessible through the following path “..\ProSim\Getting started\ProSec\”The documents are also accessible via the ProSim support internet website with your username and password (https://www.prosim.net/en/log-in/)The new Getting Started is: “SPECIFIED TABULATED DATA” that presents step by step how to specify tabulated thermodynamic data instead of the ones given automatically by the thermodynamic server, taking into account or not the effect of the pressure on the enthalpy curves.
