Abstract
Since the first prototype of Soft-Top for covering storage tanks was invented and tested on the biomass conversion plant at Farsoe, Denmark, in 1990-91, the interest in coverings for storage tanks has grown. The advantages these coverings give are a better utilization of biomass` gas potential by the collection of wastes with gas potential in the storage tanks, the elimination of ammonia and methane emission to the atmosphere, the improvement of the value of nitrogen fertilizers in the degassed liquid manures and the reduction of odour emitted from the storage tanks. The Soft-Top covering was demonstrated on a storage tank in Vegger which has a volume of 600 cubic meters and an average inner diameter op 13.3 meters. It functions as a buffer storage before delivery to farmers and the degassed manure slurries remain in the tank for eight days. A Soft-Top is a floating, gas-tight membrane covering which follows the level of the manure slurry in the tank. It is based on over-pressure which means that the membrane is stretched by the gas pressure. It has a solid border and a floater of galvanized iron to which it is fixed. The biogas is sucked from the storage tank by

The biogas is sucked from the storage tank by a ventilator which, via a pressure transmitter and a transformer, regulates the pressure under the membrane. The methane is transported to the existing gas installation. The construction, which has been in operation since March, 1922, has shown itself to be stable in operation and the material is robust. The automatic control has functioned satisfactorily and can be controlled within an interval of 1mm water column. (AB)}
