Пинч-интеграция блоков гидроочистки сырья и деэтанизации и стабилизации катализата на установке Л-35-11/600

Abstract

В результате применения пинч-методов получена новая система теплообмена для процессов гидроочистки сырья и деэтанизации и стабилизации катализата на установке каталитического риформинга Л-35-11/600. Определены лишние энергозатраты в существующей схеме и проведена пинч-интеграция как для каждого блока отдельно, так и для общего проекта реконструкции данных блоков. Внедрение пинч-проектирования позволяет снизить энергопотребление для блока гидроочистки сырья на 2,2 МВт. Для блока деэтанизации и стабилизации катализата энергопотребление снижается на 0,6 МВт. Для совместной интеграции блоков гидроочистки сырья и деэтанизации и стабилизации катализата энергопотребление снижается на 4,3 МВт. Была проведена сравнительная характеристика интегрированных процессов. На основе экономически обоснованных расчетов был сделан вывод, что наиболее целесообразным является проведение реконструкции для двух данных блоков совместно, а не по отдельности. Pinch diagnostics for hydrotreating section and deethanization and stabilization catalysate section of catalytic reforming unit L-35-11/600 was carried out. Comparative economic analysis of their effectiveness after the proposed retrofit was performed for each section separately and for the total their flowsheet. The implementation of the pinch design allows to reduce power consumption for hydrotreating process by 2,2 MW, the payback period of the proposed project will be about 7 months. For the deethanization and stabilization catalysate section power consumption is reduced by 0,6 MW, the payback period of the proposed project will be about 10 months. Energy consumption for joint integration of hydrotreating section and deethanization and stabilization catalysate section reduced by 4,3 MW, the payback period of the proposed project will be about 8 months. Therefore, it was concluded that pinch design for these sections of catalytic reforming unit L-35-11/600 the most advisable to carry out for the two sections together.
