Renewable energies for future generations

Concepts, heat exchanger for energy recovery
Catalytic hydrothermal high-pressure gasification HTG (supercritical)

Energy dissipation and global warming cause damage to the nature and to the environment and thereby challenge our future. You can do a lot to prevent it.

Concepts, heat exchanger for energy recovery
For instance, with innovative concepts and heat exchanger solutions for energy recovery so that water, wastewater, process fluids and exhaust vapours at the source in the building, in the industry, transported in the canalisation to the sewage treatment plan and even in the surface waters can be rendered useful thermally through heat transfer. Apart from the ecological aspects, such investments in the realm of renewable energies are economically consequential.

With KASAG as your partner for planning, design, engineering, and the construction of heat exchanger plants for energy recovery from waste heat, you are acting in favour of sustainability.

Catalytic hydrothermal high-pressure gasification of aqueous biomass and waste
Catalytic hydrothermal high-pressure gasification (HTG) allows energy and nutrients to be recovered from aqueous biomass and waste during their disposal. It is based on years of research at the Paul Scherrer Institute (PSI) in Switzerland and is a patented method. Aqueous biomass and waste do not have to be dried before the process is initiated, nor do they need to have a dry matter content of 10–30%. All that is required of them is that they can be pumped. This innovative method allows biomass and waste to be converted into methane and nutrients within just a few minutes.

Potential customers are private and public organisations, forestry and agricultural firms, waste disposal firms, waste recyclers and energy producers that have access to biomass inputs derived from animal and plant matter, as well as organic waste from industrial plants.

Using the catalytic hydrothermal high-pressure gasification (HTG) method, biomass components in the feed are converted into biogas/methane, allowing recovery of nutrients, such as phosphorus and nitrogen in the form of ammonium salts and minerals. If the main aim is waste disposal, the biogas/methane generated together with the nutrients makes a valuable contribution to reducing disposal costs or can even generate a profit from the method. Once refined into biomethane, the biogas produced with this method can be fed into the public gas network or converted directly into electricity in a combined heat and power plant. The nutrients recovered are processed further in accordance with their intended use (e.g. as fertiliser).

Since 2010, KASAG has been involved in the development and construction of apparatus and plant for the industrial use of catalytic hydrothermal high-pressure gasification (HTG). You are ensuring sustainability by selecting KASAG as your partner in the conception, design, engineering and construction of plant and processes
