Abstract
Способ служит для генерирования газообразного сжатого кислородного продукта низкотемпературным разделением воздуха в дистилляционной колонной системе (50, 51), которая включает колонну (50) высокого давления и колонну (51) низкого давления. Весь исходный воздух сжимают в основном воздушном компрессоре до первого давления (p1), которое по меньшей мере на 4 бар (0,4 МПа) выше, чем рабочее давление колонны (50) высокого давления. По меньшей мере часть (2, 20, 40) сжатого исходного воздуха (1) охлаждают в основной теплообменной системе (3) в косвенном теплообмене по меньшей мере с одним возвратным потоком (54, 58, 60, 62, 72) из дистилляционной колонной системы (50, 51) и вводят в дистилляционную колонную систему (50, 51). Первый воздушный поток (2, 4, 10, 12), который образуется из первой части исходного воздуха (1), сжатого до первого давления, повторно сжимают в поджимающем компрессоре (5) до второго давления (р2), которое выше, чем первое давление (p1). Повторно сжатый первый воздушный поток (6) вводят при втором давлении (p1) в основную теплообменную систему (3) и там охлаждают до первой промежуточной температуры (Т1). Охлажденный первый воздушный поток (10) производит работу при расширении в первой турбине (11). По меньшей мере часть производящего работу при расширении первого воздушного потока (12) вводят в дистилляционную колонную систему (50, 51). Второй воздушный поток (20), который образуется из второй части исходного воздуха (1), сжатого до первого давления, вводят в основную теплообменную систему (3) и там охлаждают до второй промежуточной температуры (Т2). Охлажденный второй воздушный поток (21) производит работу при расширении во второй турбине (22). По меньшей мере часть производящего работу при расширении второго воздушного потока (24) вводят вThe method serves to generate a gaseous compressed oxygen product by low-temperature air separation in a distillation column system (50, 51), which includes a high pressure column (50) and a low pressure column (51). All the source air is compressed in the main air compressor to the first pressure (p1), which is at least 4 bar (0.4 MPa) higher than the working pressure of the high-pressure column (50). At least part (2, 20, 40) of compressed source air (1) is cooled in the main heat exchange system (3) in indirect heat exchange with at least one return flow (54, 58, 60, 62, 72) from the distillation column (50, 51) and injected into the distillation column system (50, 51). The first air stream (2, 4, 10, 12), which is formed from the first part of the source air (1), compressed to the first pressure, is recompressed in the biasing compressor (5) to the second pressure (p2), which is higher than the first pressure (p1). The recompressed first air flow (6) is introduced at the second pressure (p1) into the main heat exchange system (3) and is cooled there to the first intermediate temperature (T1). The cooled first air stream (10) performs work during expansion in the first turbine (11). At least a part of the workmanship, when expanding the first air stream (12), is introduced into the distillation column system (50, 51). The second air stream (20), which is formed from the second part of the source air (1), compressed to the first pressure, is introduced into the main heat exchange system (3) and cooled there to the second intermediate temperature (T2). The cooled second air stream (21) performs work while expanding in the second turbine (22). At least a part of the work that is performed during expansion of the second air flow (24) is introduced into
