Weltec builds biogas plant near Seoul

Weltec Biopower starts building a biogas plant in South Korea. The plant is being set up in the province of Gyeonggi-do, some 60 km north of Seoul, and will transform biogas into heat in an integrated gas boiler. As early as spring 2021, the seven megawatt plant is to go live and digest up to 93,000 tons of food waste a year, some of which will also come from local households. 

Every day, two bioreactors are filled with more than 250 tonnes of food leftovers. "For this purpose, we customized the two duplex steel digesters of the newest generation with a capacity of 6,200 and 2,700 m³, respectively, to the conditions on site“, says Vladimir Bogatov, the responsible sales manager for Asia. "Due to the space limitations on site and local requirements, the tanks are very slim and have a height of 8.80 m“, says Bogatov.

The raw materials will arrive in processed form and will be fed into the plant as a ready-to-use liquid mix. The upstream storage units will be equipped with special mixing and pump technology. And the custom-developed SPS-based LoMOS control system will ensure uninterrupted heat supply. The sustainable cycle finishes with the processing of the digestate in a clarification stage. The solid matters generated in this process are used for composting.

The project stands out with its efficient transformation of the versatile biogas into heat. In South Korea, law supports the use of green and sustainable heat. Therefore, the climate-friendly energy source from technically mature biogas plants is set to unleash its potential.
