Abstract: A manifold battery for hydrocarbon fields has an entrance manifold which is connected to a plurality of separators which are operatively connected through ducts and valve sets, with gas storage devices and a pair of circulating pumps. A purging chamber is also provided which is connected to the storage devices and to the separators. An auxiliary tank reduces the adverse impact to the environment, accidents, dangers and consequential risks of flammable, toxic and damaging substances concentration, as well as reducing the operative times and the related costs.
