The process includes extracting a first nitrogen stream from the MP column, warming a first portion of the first nitrogen stream in a heat exchanger, thereby producing a product nitrogen stream, and warming a second portion of the nitrogen stream in the heat exchanger, thereby producing warm nitrogen stream. Expanding the warm nitrogen stream in an expander, thereby producing a quantity of work, and a low pressure nitrogen stream and introducing the low pressure nitrogen stream into the LP column. Extracting a second nitrogen stream from the LP column, cooling the second nitrogen stream in condenser, thereby producing a liquid nitrogen stream.

摘要： The invention relates to a method for renovating a combined system consisting of a blast furnace supplied with an oxidant fluid received at least partly from an air/gas separation unit (ASU). The method consists in injecting, before renovation, at least 50% of the flow rate of the blower feeding the blast furnace into an ASU to produce oxygen whose purity is greater than 90% by volume of O2 which feeds the blast furnace, in controlling the blower airflow rate and the pressure of the air derived therefrom by a regulator which measures the flow rate and/or pressure at the input and/or output of a cleaning stage which is mounted upstream of the separation unit to control the flow rate and pressure of the air derived from the blower. The fluid feeding the blast furnace consists of pure oxygen or diluted by air produced by the cryogenic separation unit.

This process also includes burning a fuel stream with said heated pressurized oxygen stream to produce a flue gas stream. This process also includes heating said heated pressurized nitrogen stream to form a hot pressurized nitrogen stream. This process also includes work expanding said hot pressurized nitrogen stream to a lower pressure thereby forming a hot exhaust nitrogen stream and recovering energy. And this process also includes heating said boiler feed water stream by indirect heat exchange with said hot exhaust nitrogen stream.

摘要： Nitrogen gas at a single pressure is produced from a two-column cryogenic distillation of air. The bottoms liquid product from the high pressure column is divided into two portions, one of which is vaporized and then turboexpanded before its entry into the low pressure column as a feed stream. By these means, no stream bypasses the double distillation process, further enhancing nitrogen recovery and achieving low specific energy consumption for nitrogen product.

摘要： Pressurized gaseous nitrogen (“GAN”) is produced in a process in which liquid nitrogen (“LIN”) is produced in a cryogenic air separation unit (“ASU”). The pressure of at least a portion of the LIN is increased to produce pressurized LIN. A fluid having an oxygen concentration at least equal to that of air is separated in an auxiliary cryogenic distillation column to produce nitrogen-rich overhead vapor and oxygen-enriched bottoms liquid. Heat and optionally mass is transferred between at least a portion of the nitrogen-rich overhead vapor and at least a portion of the pressurized LIN to produce nitrogen-rich liquid and pressurized GAN. At least a portion of said nitrogen-rich liquid is used as reflux to the ASU after suitable pressure adjustment. Such a process allows the production of high purity GAN without the loss of oxygen recovery typically observed in conventional pumped LIN cycles.
