Heat Exchanger
The AAT heat exchanger is used to heat the digester sludge in the digester. For perfect fermenterind conditions,a constant sludge temperature is required in the digester. In order to achieve this, the digester sludge is circulated in a pipe heat exchanger and is heated to the requested temperature through hot water in a counterflow procedure. With respect to sludge quality, performance and energy efficiency, the heat exchangers are optimisted for the ...

Low Pressure Gas Storage
The gas holder shell consists of a cylindrical tank with a conical roof constructed of glass lined steel plates. To store biogas at (near) constant pressure the membrane is pressurized by a horizontal steel plate (loaded with concrete blocks). Stabilized by a guide pillar the steel plate travels between gas holder floor and roof. Access to the upper part of the gas holder (aerated head space) is provided via outside ladder, outside platform and manhole. ...

Double Membrane Gas Storages
The outer membrane forms the actual protective construction and is always under a for the statics necessary positive pressure. Through a built-in viewing window the operations inside can be observed at any time. The actually usable holder forms the inner membrane. This membrane moves up or downwards depending on the filling level. In the gas holder with base plate a bottom membrane seals the storage space to the concrete foundation. With the help of the ...
