PM and NOx removal from stationary engines exhaust

Stationary applications, such as gen-sets operate by nature in different modes compared to engines used in the on-road sector. On the other hand, the design priorities and exhaust system specifications are also different and sometimes stricter especially with respect to durability, maintenance and effects on operational costs.

exothermia suite works closely with this particular industry sector offering cost-efficient model-based solutions for the design and control of such systems.

3-way catalysts for two-wheelers

Exothermia use-case-industries

The emission reduction and on-board monitoring requirements for two-wheelers is putting high pressure to this cost-sensitive industry.

exothermia suite offers tools and engineering services for catalyst design, control and diagnosis optimization using – and adapting when necessary – the experience obtained from the automotive sector.

SCR on filter for off-road applications

exothermia iindustries-cases

Off road engines will require both PM and NOx emission control technologies that will fulfill the emission limits over long useful lives. The design and control optimization of a multi component EAT system is impossible without resorting to advanced CAE methods and tools accounting for long-term deterioration effects and failure mode analysis.

SCR on filter presents a most interesting case with non-obvious impacts of ash and ageing interactions on NOx conversion, NH3 slip and pressure drop. exothermia suite proposes new models and simulation environment setups to provide timely answers to complex problems.

SCR for marine engines

Recent and upcoming regulations for NOx emissions in marine applications require the installation of large and expensive deNOx equipment. Due to the extremely high testing and optimization efforts and costs associated with the certification process, it will be necessary to rely on well established predictive models.

Based on the experience already acquired on the on-road sector, exothermia suite is ready to support the engine and supplier industry to deal with this challenging engineering task.

Passive SCR Aftertreatment Systems

In 2020, Exothermia released a publication entitled “Model-Based Comparison of Passive SCR Aftertreatment Systems for Electrified Diesel Application”, jointly prepared with Punch Torino SpA, former GM Global Propulsion Systems Torino. This was presented in the 2020 “CO2 Reduction for Transportation Systems Conference” virtual event (July 7th-9th https://conferences.ata.it/). The article demonstrates a model based benchmarking of various powertrain topologies and exhaust aftertreatment (EAT) configurations, aiming at optimizing fuel consumption – emissions – & system cost tradeoff for a Diesel HEV. EAT system modeling has been performed using some of the advanced feature of exothermia suite, including electrically heated catalyst models and virtual sensors/controllers.

Emission Control Technologies for Zero Carbon Fueled Engines

Emission Control Technologies for Zero Carbon Fueled Engines

 

Τhe enterprise EXOTHERMIA SA, which is headquartered in the Region of Central Macedonia, was co-financed by the European Regional Development Fund (ERDF) of the European Union for the implementation of its project under the Action “Investment Plans of Innovation“ in the Region of Central Macedonia, under the framework of the Operational Program “Central Macedonia 2014-2020.”

The Action aims to assist enterprises and research organizations in implementing research projects.

The use of carbon-free fuels in internal combustion engines is a very attractive solution in the direction of CO2 emissions reduction. In road transport, the use of hydrogen (H2) as a fuel in internal combustion engines is proposed as a clean fuel for LD/HD vehicles. At the same time, in the field of maritime transport and in line with the IMO’s proposed strategy for reducing CO2 emissions from ships, the use of ammonia (NH3) as a marine fuel will be adopted at increased rates.

In this investment plan, Exothermia SA intends to develop new simulation models and acquire know-how in the emerging area of ​​zero-carbon engines. Specifically, the project aims to investigate the operation of H2 and NH3 fueled combustion engines with the respective de-NOx after-treatment systems using testing and modeling methods. The target is to develop a complete simulator to be used in the combined optimization of combustion and emissions after-treatment in on-road and marine applications.

Investment’s total budget is 399,430€ out of which 319,544€ is public expenditure.  The Action is co-financed by Greece and the European Union – European Regional Development Fund.

The approved investment plan includes the following categories of investment:

  • Staff costs
  • Expenses of instruments & research equipment
  • Expenditure on contract research, knowledge and patents
  • Additional overheads and other operating expenses
  • Expenditure on patents and other intangible assets
  • Expenditure on the secondment of highly qualified staff to new posts created for the purpose of the project

For decades we used to treat heat as a low-value, unwanted energy form, an indicator of inefficiencies. Diesel engine engineers, on the other hand, are struggling to use every Joule of heat available in the exhaust gases to keep the catalysts active, especially under city driving conditions.

As our name implies, we feel comfortable with heat and our everyday work is to help engineers make best use of it.

Indeed, a bunch of technologies are available to keep the exhaust system warm, all of them requiring some extra fuel, so the question is how to achieve your emission targets with the least fuel and CO2 penalty.

With the valuable support of the co-Funded project ‘Thermatech’, we are determined to develop the most comprehensive model-based approach to deal with the complexity of this trade-off problem in the early development phase. Combining our expertise in testing & modeling Diesel engines, exhaust systems and heat exchangers, we will trace every bit of energy and heat flow at component and system level over the next couple of years.

Many thanks to Greek Ministry of Development of Greece for selecting our research proposal and co-financing the project through the European Regional Development Fund of the European Union and Greek national funds in the frame of the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call RESEARCH – CREATE – INNOVATE (project code: Τ1EDK-01120)
