Kemira Oy has built a demonstration ammonia plant based on peat. The cost of the project amounted to FIM 230 million. Production was started in the autumn of 1988. The existing oil-based ammonia plant was modified to use peat additionally in production.

Peat gasification was in production use with partial capacity for thousands of hours together with oil gasification. The problems encountered were due to the heterogeneous quality of peat. Difficulties were also caused by the high naphthalene content of gas and by blockages in the cyclone-recycle pipe of the gasification. Technical solutions for these problems were available, which proves that the production of synthesis gas and ammonia from peat on a commercial scale is technically possible.

Extensive research supporting the commercial peat-ammonia venture was carried out within the JALO research programme in co-operation between Kemira and the Technical Research Centre of Finland (VTT). The experience obtained in these projects is alse relevant to the development of IGCC power technology.
