Viridis offers catalyst standardization, testing and aging services for automotive applications

Automotive Catalyst Aging

Monolith catalysts can be aged under controlled conditions to end of life conditions (mil-on). We work with the OEMs, catalyst manufacturers to recommend the target aging conditions. Aging conditions of the catalysts vary depending on the desired end state of the catalyst. Hydrothermal aging, cyclic aging and simulated exhaust aging conditions are possible for core and full scale catalysts. Please contact us at info@viridischemicals.com for additional information regarding our aging capabilities.

Automotive Catalyst
Core Testing

Several countries are advancing from a fixed cycle testing (FTP, NEDC, MIDC etc.) to RDE testing which requires accurate catalyst predictive models in the ECU (engine control unit). Catalyst core testing involves cutting a core sample from the full scale catalyst and test it under controlled concentration and temperature domains to assess the performance and identify the problematic operating conditions. Viridis performs core testing for SCR, DOC, LNT, TWC and ASC catalysts over wide operating conditions.

Viridis provides Matlab Simulink® based architecture that can easily be converted to ECU based language (IEC 61131-3 structured text)

Petroleum Catalysts and Process Development in Matlab / Simulink®

Viridis develops customer specific models for various petroleum catalyst processes by utilizing customer data or in-house catalyst testing data. Models are built and delivered in Matlab/Simulink® environment that give the customer a direct access to various physical and chemical processes in the system. As a first step the reaction chemistry is developed and incorporated in the base model. Then different components in the customer specific refinery are incorporated into the final model (such as distillation columns, reboiler, separator etc.) to simulate the process performance.
Such models are extremely useful to the customer not only during start-up and emergency/normal shut-down processes, but also when the process encounters non-optimal operating/feed conditions. Simple simulations and parametric studies with these models will allow the user to perform the desired corrective actions with minimal loss in operational efficacy.

Petroleum Catalysts and Process Development in Matlab® and Aspen – HYSYS®

Viridis develops customer specific reactor models for various petroleum catalyst processes by utilizing customer data or in-house catalyst testing data. Models are built and delivered in Matlab/Simulink® environment that give the customer a direct access to various physical and chemical processes in the system. The reaction chemistry is developed and incorporated in the base Matlab/Simulink model.

Viridis’ models can be directly integrated into existing Aspen – HYSYS® models to simulate the entire process in the refinery. These user-based reactor models give additional flexibility to control the mass transfer characteristics, reaction enthalpies and reaction kinetics specifications (i.e. limiting equilibrium conversions) etc.

These integrated models are extremely useful to the customer not only during start-up and emergency/normal shut-down processes, but also when the process encounters non-optimal operating/feed conditions. Simple simulations and parametric studies with these models will allow the user to perform the desired corrective actions with minimal loss in operational efficacy.

Viridis offers this software as a one time license with open source allowing the end user to modify and tune the model depending on their specific requirement. Please reach out to us at info@viridischemicals.com for additional information regarding petroleum process models.
