nitrogen generator

A modular nitrogen generatorincluding a housing including a bracket and defining an interior space, a flow path having an inlet adapted to receive compressed air and an outlet in fluid communication with a storage tank, an inlet manifold, an outlet manifold, and a modular membrane canister supportable on the mounting bracket within the interior space and positioned along the flow path between the inlet manifold and the outlet manifold to receive compressed air from the inlet manifold, extract nitrogen from the compressed air, and deliver the nitrogen to the outlet manifold. The flow path can be adapted to receive an additional modular membrane canister in a parallel flow configuration with the modular membrane canister to increase nitrogen output capacity of the nitrogen generator.

In one embodiment, the invention provides a modular nitrogen generator including: a housing including a bracket and defining an interior space, a flow path having an inlet adapted to receive compressed air and an outlet in fluid communication with a storage tank, an inlet manifold, and an outlet manifold. The inlet manifold and the outlet manifold extend through the housing and can be positioned along the flow path between the inlet and the outlet. The modular nitrogen generator further includes a modular membrane canister supportable on the mounting bracket within the interior space and positioned along the flow path between the inlet manifold and the outlet manifold to receive compressed air from the inlet manifold, extract nitrogen from the compressed air, and deliver the nitrogen to the outlet manifold. The flow path can be adapted to receive an additional modular membrane canister in a parallel flow configuration with the modular membrane canister to increase nitrogen output capacity of the nitrogen generator, and the bracket can be adapted to support the additional modular membrane canister in the interior space.

In another embodiment the invention provides a method of operating a modular nitrogen generator. The method includes the acts of: providing the nitrogen generator with a housing including a bracket and defining an interior space, an inlet manifold, an outlet manifold, an outlet, and a first modular membrane canister connected between the inlet manifold and the outlet manifold, The method further includes supplying compressed air to the first modular membrane canister through the inlet manifold, separating nitrogen from the compressed air as the compressed air flows through the first modular membrane canister, directing the separated nitrogen from the first modular membrane canister to the outlet manifold, directing the nitrogen from the outlet manifold to the outlet, and coupling a second modular membrane canister to the bracket, coupling a first end of the second modular membrane canister to the inlet manifold, and coupling a second end of the second modular membrane canister to the outlet manifold, such that at least some of the compressed air is directed away from the first modular canister and through the second modular membrane canister to expand nitrogen output capacity of the nitrogen generator.
