Manifold battery for hydrocarbon fields

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.

1 . A manifold battery for hydrocarbon fields comprising:
 an entrance manifold connected to a plurality of separators, which are operatively interconnected through valve ducts and valve sets,   a gas storage device and a set of circulating pumps, and   a purging chamber connected to said storage device and said separators, and   an auxiliary tank connected to said separators and to said circulating pumps through the respective ducts and valves sets, and   wherein said manifold comprises a three-way valve disposition which present at least a general line and at least a control line,   said plurality of separators is connected to said general and control lines, and comprises at least two control separators and at least two general separators connected among themselves,   wherein at least one of said gas storage devices is a reserve gas vessel for instruments.   
     
     
         2 . The battery of  claim 1 , wherein since each of said control and general separators are connected to entrance valves and to control valves. 
     
     
         3 . The battery of  claim 2 , wherein said control and general separators are provided with outlet valves and a relief valve. 
     
     
         4 . The battery of  claim 1 , wherein said control separators have a level sensor, a pressure sensor and a mass sensor, while said general separators have at least a level sensor and a pressure sensor. 
     
     
         5 . The battery of  claim 4 , wherein said control separators and general separators have a level controller, a sensor, a pressure transmitter, and a continuous level controller. 
     
     
         6 . The battery of  claim 1 , wherein said auxiliary tank is provided with at least an entrance valve, a pneumatic control valve, at least an overflow pipe and a pneumatic controller configured with a pressure lower than the separators working pressure. 
     
     
         7 . The battery of  claim 1 , wherein said gas storage devices also comprise a gas general separator which is connected to said purging chamber and to said gas vessel by means of a gas measuring bridge. 
     
     
         8 . The battery of  claim 7 , wherein said gas measuring bridge comprises a first pneumatic valve and a second relief or venting pneumatic valve, said first valve being connected to said gas general separator, while said second valve is connected to a burning ditch. 
     
     
         9 . The battery according of  claim 1 , wherein said circulating pumps comprise a first operating pump and a second auxiliary pump. 
     
     
         10 . The battery according of  claim 9 , wherein said circulating pumps comprise a double effect piston, with a flow of at least 185 m3/h at a minimum maximum working pressure of 75 kg/cm2, and a minimum suction pressure of at least 1 Kg/cm2.
