Booked contracts increased over 65% in 2016

The total value of accepted term contracts signed and order received by ProSim during fiscal year 2016 are up 65.6% compared to the previous year.
Over this period, many companies from Europe, North-America and other parts of the world have joined ProSim’s customers list. It is interesting to notice that many of these new customers switched from other suppliers of process simulation software to ProSim. Moreover, the use of our software among our long-term customers is progressing with new licensed sites, with the acquisition of other ProSim software, increasing number of licenses or moving from local licenses to network licenses.

"We have never seen such a progression before and it is very exciting for ProSim," said Stéphane Déchelotte, CEO of ProSim. "I feel that today many companies marked a turning point. After a serious review of our offer and in a context of cost cutting, they decide to turn to ProSim solutions. I also believe that this is the result of many years of efforts to develop competitive software, and the benefits of high standards we maintain in the quality of our services."

Modeling of Divided Wall Columns (DWC)

Divided Wall Columns (DWC) are an interesting innovation to improve the energy efficiency of separative processes by distillation. However, they are still too little used in the industry; due to a lack of experience when sizing Divided Wall Columns. The simulation of this type of equipment has long been possible in a process simulator such as ProSimPlus by splitting the divided wall column into 2( or4) interconnected "sub-columns". But this requires a correct initialization of the intermediate streams and knowledge of the parameters for each of the "sub-columns" (number of theoretical stages). Only a few methods have so far been available for this and none have been implemented in a process simulator.

Relying on the work conducted at the Laboratoire de Génie Chimique (LGC - by Professor Michel Meyer's team, a new dimensioning method has been implemented in ProSimPlus. This includes a short-cut method for simple distillation, where it is now possible to determine the main parameters of each of the 2 (or 4) columns in order to obtain the desired separation. The new SHORTCUT DWC unit operation allows you to size a distillation column with a separation wall, with a feed and three products: the distillate, the waste, and the intermediate sidestream. Specifying the recovery rate of the three key-compounds for each outlet stream and some operating constraints allows the unit operation to calculate a sizing by theoretical stages, and the initializations for the intermediate streams required for a rigorous calculation.

The rigorous simulation (plate by plate) of such columns with partition is then easy. The methods implemented in ProSimPlus have been experimentally validated using the pilot installation of the LGC.

Scale-up of batch reactor with BatchReactor

The BatchReactor software has demonstrated its usefulness for optimizing the operating conditions of discontinuous chemical reactors, for conducting safety studies on such reactors, while controlling temperature and pressure, and also for scale-up between laboratory equipment, pilot plant and the industrial unit.
In order to further facilitate these scale-up phases, new functionalities have been added and, in particular, the possibility of performing an extrapolation calculation for a mechanically stirred tank:
        - Values of the characteristic variables (rotation speed, power ...) as a function of the invariant retained (power density ...).
        - New geometry taking into account the extrapolation factor (geometric similarity).
        - Extrapolation of gas supplies (surface velocity or constant vvm).
        - Calculation of vortex depth (in the absence of baffles).  
It is also now possible to define several identical agitators on the same shaft for a given number of the available mixing devices. The high-efficiency thin blade Chemineer HE3 propeller has also been added as well as the turbine with curved-blades at the turbine bottom (Pfaudler type).

These improvements were implemented in BatchReactor, and also in BatchColumn software (simulation of batch distillation columns) where the boiler can be a stirred tank

Acid nitric industry: collaboration in process simulation between ProSim and Johnson Matthey Plc.

ProSim collaborates with Johnson Matthey Plc to allow nitric acid manufacturers to further enhance the performance of their plants.

Thanks to this partnership, Johnson Matthey will actively market and support the sales of ProSimPlus HNO3 software, while Johnson Matthey will be ProSim's exclusive catalyst supplier customer within the nitric acid industry. Both companies will collaborate in flowsheeting simulation work by applying their know-how and expertise in the nitric acid industry as a service for customers, aiming to resolve issues and optimise plant operations. Further joint developments in the catalyst modelling aspect of the simulation will also benefit operating firms and engineering companies.
