Abstract
The present invention relates to a novel integrated system for providing nitrogen (N2) to a variety of industrial service applications such as, for example, process unit drying, pipeline purging, reactor cooling, vessel inerting, pipeline displacement.
Claims14
An integrated system for providing nitrogen to a temporary industrial service application, comprising:
- at least one mobile pressure swing adsorption unit for providing a baseload of nitrogen fluid having a first specification to a nitrogen service application;
- at least one mobile liquid N2 fed system for providing supplemental nitrogen at a second specification to the nitrogen service application, wherein the combined baseload and supplemental nitrogen provide a product nitrogen stream at a predetermined flow rate, temperature, pressure, and purity as required by the industrial service application.
An integrated process for providing nitrogen to a temporary industrial service application, comprising:
- providing a compressed feed stream to at least one mobile nitrogen pressure swing adsorption unit and separating a baseload of nitrogen fluid having a first specification from an oxygen enriched waste steam;
- providing a supplemental nitrogen via a liquid N2 fed system wherein the supplemental nitrogen is provided at a second specification, and combining the supplemental nitrogen with the baseload nitrogen fluid producing a product nitrogen stream at a predetermined flow rate, temperature, pressure and purity as required by the industrial service application.
An integrated process for providing nitrogen to a temporary heating service application, comprising:
- providing a compressed air feed stream to at least one mobile nitrogen pressure swing adsorption unit and separating a baseload of nitrogen fluid having a first specification from an oxygen enriched waste steam and where said baseload nitrogen fluid is at a lower temperature than required by the heating application;
- providing a supplemental nitrogen via a liquid N2 fed system wherein the supplemental nitrogen is provided at a second specification and where the supplemental nitrogen is at a higher temperature than required by the heating application, and combining the supplemental nitrogen with the baseload nitrogen fluid producing a product nitrogen stream at a predetermined flow rate, temperature, pressure and purity as required by the heating service application.
An integrated process for providing nitrogen to a temporary cooling service application, comprising:
- providing a compressed air feed stream to at least one mobile nitrogen pressure swing adsorption unit and separating a baseload of nitrogen fluid having a first specification from an oxygen enriched waste steam and where said baseload nitrogen fluid is at a higher temperature than required by the cooling application;
- providing a supplemental nitrogen via a liquid N2 fed system wherein the supplemental nitrogen is provided at a second specification and where the supplemental nitrogen is at a lower temperature than required by the cooling application and combining the supplemental nitrogen with the baseload nitrogen fluid producing a product nitrogen stream at a predetermined flow rate, temperature, pressure and purity as required by the cooling service application.
