Abstract
A method of applying liquid anhydrous ammonia to soil is disclosed as including the step of pressurizing anhydrous ammonia received from a source. The pressurized anhydrous ammonia is conducted to a plurality of terminal outlets, wherein each of the outlets is configured to maintain a back pressure and thereby the liquid state of the anhydrous ammonia. The anhydrous ammonia is discharged from the plurality of terminal outlets to thereby contact the soil.
Claims32
An anhydrous ammonia application method for applying liquid anhydrous ammonia to soil, said method comprising the steps of:
- (a) pressurizing anhydrous ammonia received from a source to a variable pressure level within a conduit;
- (b) conducting the anhydrous ammonia through the conduit to a plurality of terminal outlets, wherein each of the plurality of terminal outlets has a restrictive orifice for maintaining an anhydrous ammonia back-pressure;
- and
- (c) discharging the anhydrous ammonia from the plurality of terminal outlets, with discharged liquid anhydrous ammonia contacting the soil.
An anhydrous ammonia application method for applying liquid anhydrous ammonia to soil, said method comprising the steps of:
- (a) pressurizing anhydrous ammonia received from a source;
- (b) after step (a), conducting the anhydrous ammonia to a manifold, said manifold capable of receiving the anhydrous ammonia through a manifold inlet and discharging the anhydrous ammonia through a plurality of manifold outlets;
- (c) after step (b), conducting the anhydrous ammonia from each of the manifold outlets to a respective one of a plurality of terminal outlets, wherein each of the terminal outlets has a restrictive orifice for maintaining an anhydrous ammonia back-pressure, wherein an accumulator is connected in fluid-flow communication with the manifold and fluidly interposed between the manifold inlet and the plurality of manifold outlets, said accumulator operable to dampen pressure surges in the anhydrous ammonia flowing through the manifold;
- and
- (d) discharging the anhydrous ammonia from the plurality of terminal outlets, with discharged liquid anhydrous ammonia contacting the soil.
An anhydrous ammonia application method for applying liquid anhydrous ammonia to soil, said method comprising the steps of:
- (a) separating an anhydrous ammonia source flow into multiple discharge flows;
- (b) dampening any pressure surges of the anhydrous ammonia source flow;
- (c) maintaining the pressure of the anhydrous ammonia above vapor pressure as the source flow is separated into the discharge flows;
- and
- (d) discharging each of the discharge flows, with discharged liquid anhydrous ammonia contacting the soil.
