Abstract
In relation to a biomass conversion plant producing methane, a storage tank for manure slurries from which the gas which is usually let free (to the irritation of neighbours because of its odor) can be produced, and which will also provide extra storage capacity, has been designed and produced by a Danish firm. It is covered in order to reduce odor. The firm plans to develop a new type of `stirrer`, centrally placed and divided into three sections (pipes) at the base. This `propeller` drives the stream of manure slurry to the base of the tank where it is lead into the three pipes and along the base and then out towards the sides of the tank. After this the stream will be forced up the sides of the tank and up towards the surface. Then it will be sucked down into the center and down into the central tube again. In this way surface scum will be avoided. It is suggested that the tank itself should be constructed of bolted steel plates. This type of tank with stirrer is described in detail. It was found that the use of the tank will lead to methane recovery to the extent
