MOBILE NITROGEN SERVICE SUPPLY SYSTEM Russian patent published in 2022 - IPC B01D53/47 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel integrated system for supplying nitrogen for various industrial service processes, such as, for example, drying of process plant, blowing of pipelines, cooling of reactors, creation of inert atmosphere in vessels, displacement from pipelines. Integrated system for supply of nitrogen for a temporary industrial service process comprises at least one mobile adsorption unit at variable pressure to provide a basic volume of consumed nitrogen fluid, having first technical characteristics, for service process requiring nitrogen; at least one cryogenic storage vessel containing a cryogenic product in liquid form, located in front of at least one pump unit to be installed on a trailer and filled with N₂ or evaporator installed on trailer for supply of liquid nitrogen to them to provide additional nitrogen, having second technical characteristics, for service process requiring nitrogen, wherein combined basic volume and additional nitrogen provide product nitrogen flow with preset flow rate, temperature, pressure and degree of purity in compliance with industrial servicing process requirements.

EFFECT: creation of a mobile nitrogen supply system having a mobile PSA generator to provide a basic volume of nitrogen for various industrial servicing processes, as well as creation of mobile versions of PSA generator and liquid nitrogen supply system for temporary supply of N₂ for various service technological processes.
