SEID was started back in 1997 as Applied Plasma Physics (APP) with the core technologies ModuPlasma and ModuPower (High-Frequency Switch-Mode) Power Supply technology.
Schenck Process Group (SPG) acquired APP in 2014, but in May 2020 SEID emerged as Norwegian owned and managed entity, after an MBO from SPG, new name, but same technology and focus areas.
SEID will also in the future remain focused on environmental solutions based on our proprietary Non-thermal Plasma (NTP) system, ModuPlasma and as well as enhanced UV systems and reinforced NTP concepts. 2020 will also see the introduction of our next generation NTP system, the ModuPlasma High-Density system.
We will strengthen our presence in the market by expanding our international footprint, and we will have more opportunities to support our customers and business partners in the ongoing development of their processes. Our new organisation can provide a broader and more focused range of services than ever before.
Efficient. Safe. Precise
For our old or new customers around the world, SEID systems and components are a guarantee of maximum reliability and precision, with our core products ModuPlasma and ModuPower
SEID sets new quality and environmental standards
To reduce NOx and CO² emissions in power plants, the flow of fuel and subsequent optimum combustion is crucial. The increasing use of biomass to provide low carbon, cost-effective and reliable renewable power requires handling systems that minimise dust to give a clean and safe environment. We also offer comprehensive solutions to address filterable particulate matter emissions or simply reduction/removal of NOx and SO2.
Our products lower baseline emission rates, reduce emissions during transient operating conditions and manage changes in inlet grain loading, fuel chemistry and gas flow.
We operate worldwide, wherever we’re needed.
Through our global presence, we can provide local resources to support the individual requirements of our customers. SEID provides expertise from concept development through the life of our equipment. We can meet different customer needs while maintaining excellent customer service around the world.
ModuPower™ is a modular SMPS concept where a unit may be tailored to fit your individual need for secondary voltage and current while still being a standard piece of equipment.
The modularity has an inherent fault tolerance as the ModuPower™ can continue to operate with single module failures. Liquid cooling for all power components; IGBT’s, inductors and High Voltage transformers.
This is the solution generally accepted as the most efficient and rugged method for cooling power electronics.
Switch Mode Power Supplies – SMPS – High Frequency power supplies
SMPS are the most efficient alternative for energizing ESP’s due to small output ripple, extremely fast spark recovery and superior energy efficiency.
- Competitive pricing and reduced service cost gives lower cost of operation
- Easy installation and exchange
- Modularity considerably shortens outage time
- Increased particle collection reduces wear and tear on fans, scrubbers etc
Increased ESP performance
- Improve efficiency up to 95% compared to T/R’s
- Enhanced fine particulate capture
- Designed to match the need for any ESP field configuration
- Upgrades your existing filter to meet tomorrow’s requirements for fine particulate removal
The main difference between SMPS and T/R
Using SMPS technology to energize electrostatic precipitators enhances both total collection efficiency and fine particulate collection. This is achieved mainly due to the almost ripple-free high voltage signal provided by a high frequency power supply, where a traditional Transformer/Rectifier (T/R) will have a ripple similar to the low frequency – 50/60 hz – of the mains input. A direct comparision of voltage levels shows that SMPS energisation provides a higher average voltage and thus more power to the ESP.
Air pollution control
Around the world companies are facing steadily increasing demands to limit hazardous or odourous emissions from their production facilities. The institutions of the EPA in the United States and the IPPC in Europe are evidence of a new political climate. Regulations for permitting production now normally require assessors to consider potential odour and pollution impacts when reviewing applications.
As a result of urban sprawl, many production plants, originally sited at a distance from the population, now find themselves surrounded by housing. Local communities have also become more willing to use the available laws of nuisance in taking legal action against owners and operators of odour and pollution sources. Specific limits for concentrations of particulate matter and in many areas for odour have also made this type of action more likely to succeed.
All indications are that these trends are likely to continue into the future.
At SEID, we don’t only provide drastic removal of odour and dust, we also put our science and energy to do so in the most environment friendly way.
State of the art odour and particle abatement technology for the food & feed and tobacco industries
The SEID Odour and Dust Abatement System is recognized as Best Available Technique (BAT) in IPPC for Odour Abatement. The system efficiencies has been demonstrated globally in a wide variety of industrial applications. It offers a low investment cost and very low operation and maintenance cost, together with verifiable odour removal efficiencies.
Increasingly, food & feed manufacturers are being required to address the issue of release of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government legislation all bring pressure to factories to minimize real or perceived risks of contamination. There are no universally applied standards for odour or Volatile Organic Compounds (VOC) emissions, and to provide solutions that fit specific factory needs can be challenging. There is no single solution but understanding the food manufacturers problems certainly helps a great deal. In recent years, there have been numerous changes regarding where production facilities are situated.
Factory closures and relocation of manufacturing units has become commonplace. At the same time urban sprawl has resulted in residential areas being built closer to previously remote industrial areas. Another pressure companies face is meeting local environmental needs. So what does the industry need from its odour abatement equipment? This is a complex question and the answer needs to include:
- A compact design minimizing space requirements
- End of pipe solution
- Low running cost
- Minimal maintenance
- Ability to operate at normal food manufacturing temperatures, to avoid cooling costs
- High odour removal efficiency
- No chemical additions and need to maintain chemistry
- No liquid effluent waste
- Instant on/off – no warm up time
- Modular construction, ease of relocation if change of production location and ease the ability to add on modules according to required capacity
- Competitive capital cost
Odour Abatement – A friendly neighbourhood
SEID provides cutting edge solutions that can clean odours and particulate emissions; minimizing attention from neighbours and ensuring compliance with local ordinances. By installing a SEID solution at an early stage, companies can avoid costly and damaging high profile conflicts. Managers and personnel can then focus their attention on efficient production and the need for potentially much higher investments at a later stage can often be avoided.
Cleansing principles and emissions to the atmosphere:
The general cleansing principles used in the SEID non-thermal plasma technology, are to accelerate the natural destruction of the chemical composition in the process emission. Hence, there are no by-products created from the cold plasma process. The reaction chambers also function as compact electrostatic precipitators, removing dust and particulates. Due to the low energy level in the reaction zone, the SEID system is not able to “produce” any harmful by-products.
An oxidation process takes place in the plasma reactor, and causes the odour reduction to happen. Radicals generated inside the reactor initiate this process. Most of these radicals are all short lived and will be consumed before emitted out of the unit. Some O³-radicals (ozone) may however be emitted out of the unit and will contribute to a post-reaction in the ducting leading the emission to the exit point. During commissioning, O³ emission will be verified to be well below existing standards.
Dust Abatement: Highly effective Dust filters
The Plasma reaction chamber not only create a plasma zone, they also possess a very high electrical field strength and thereby act as a very efficient compact electrostatic precipitator (ESP). This means that any particulate matter and dust passing through the chambers will be strongly attracted to the sides and be removed from the gas flow. Measurements have shown that the system is very effective in removing fine dust and submicron particles of 2,5 micron (PM2,5) and below.
