High tech for biogas
SPANGLER – the Plus of Renewable Energy.
The know-how of SPANGLER Automation has already been used in more than 30 production plants for biogas. The latest project was realised in Croatia.
Cycle of biogas production
Biogas plants are fed with different organic substances such as energy crops, organic waste or liquid manure. In the plants the raw materials are bacterially processed into biogas which is mostly used for electricity and heat generation on site. Alternatively, the gas can be prepared to biomethane and fed into the natural gas grid. The remaining solid or rather liquid substances are used as agricultural fertiliser.
Behind this accelerated fermentation process, with large containers and heavy mechanics, a comprehensive and sophisticated electrical engineering can be found. For the operation of modern biogas plants more and more control systems are used in order to be able to visually present and operate the entire process of the gas production. The access to the plant control is primarily made via a PC at the plant. Instead of permanently installed local control boxes this function is taken over by a tablet PC which enables a wireless intervention and parameterising in the plant. In addition to guaranteeing an error-free production process, the safety for the operator must always be at first priority. Hazard-critical components, which could cause a risk of injury, are therefore controlled by a safety PLC such as the Siemens 1516F-3 PN/DP.
All over the world
SPANGLER realises biogas plants for various customers. Besides Germany, these were delivered among others to Singapore, Croatia, Chile or Russia. Thereby smaller plants with 500 KW and a silo filling by food waste as well as industrial plants with more than 3 MW and a feeding by energy crops were implemented. With every realised and programmed plant the know-how gained at SPANGLER is enriched and leads to a smooth process for the following plants.
