A process according to claim 1, wherein said mass transfer section (25) has 1 to 10 theoretical or practical plates. 11. A process according to claim 1, wherein said high-pressure column (4) operates at a pressure of 9 to 13 bar and said low-pressure column (5) operates at a pressure of 2 to 5 bar. 12. A process according to claim 1, wherein a nitrogen-rich gas fraction is removed from the upper region of said high-pressure column, a part (8) of said nitrogen-rich gas fraction is condensed in a condenser-evaporator (6), and at least part (10) of the resultant liquefied nitrogen-rich fraction is returned to the high-pressure column (4) as reflux. 13. A process according to claim 12, wherein another part of said nitrogen-rich fraction is used as said refrigeration fluid (31) introduced into said low-pressure column. 14. A process according to claim 12, wherein another part (14, 20) of the resultant liquefied nitrogen-rich fraction is introduced into said low-pressure column (5). 15. A process according to claim 13, wherein a further part (14, 20) of the resultant liquefied nitrogen-rich fraction is introduced into said low-pressure column (5). 16. A process according to claim 1, wherein bottom liquid is removed from said low-pressure column, supercooled, and used as said refrigerant (13) for at least partially condensing said gaseous nitrogen in said top condenser (17) by indirect heat exchange. 17. A process according to claim 1, wherein bottom liquid removed from said high-pressure column is supercooled, throttled, and introduced into a lower region of said low-pressure column. 18. A process according to claim 17, wherein another part of bottom liquid removed from said high-pressure column is supercooled, and introduced into said top condenser (17). 19. An apparatus according to claim 9, wherein said mass transfer section (25) has 1 to 10 theoretical or practical plates. 20. A process for producing high-purity nitrogen by low-temperature fractionation of air in a rectification system which comprises a high-pressure column (4) and a low-pressure column (5), said process comprising: introducing feed air (1, 3) into the high-pressure column (4), removing an oxygen-containing liquid fraction (11) from the high-pressure column (4) and feeding at least a portion of said oxygen-containing liquid fraction into the low-pressure column (5), extracting gaseous nitrogen (18) from the low-pressure column (5) above a mass transfer section (25) which has at least one theoretical or practical plate, and at least partially condensing said gaseous nitrogen in a top condenser (17) by indirect heat exchange with a refrigerant (13), and removing high-purity nitrogen (26, 27, 30) from the low-pressure column (5) below the mass transfer section (25), wherein said process further comprises a refrigeration-supply system, within which a refrigeration fluid (31, 32, 34, 38) flows and at least part of the refrigeration fluid from the refrigeration-supply system is introduced (34, 38) into the low-pressure column (5) above the mass transfer section (25) or into t
