Description

I
Изобретение относитс  к способам получени  водорода из углеводородных газовых смесей с использованием процессов охлаждени  и может, использоватьс  в нефтехимической и газовой промышленности.
Известен способ получени  водорода из углводородной газовой смеси путем последовательного охлаждени  газовой смеси, соцерукищей водород, метан, этилен, этан и фракцию С,, с вьщелением указанных компонентов. При этом оставшуюс  после выделени  газовую смесь, состо щую из водорода и 5% метана расшир ют в детантере, и полученный при расширении газа холод используют дл  охлаждени , исходной газовой смеси 1.
Основным недостатком способа  вл етс  наличие жидкой фазы при расширении метановодородной фракции в детантере, что приводи к нарушению режима его .работы.
Наиболее близким по технической сущности и достигаемому результату к предлагаемому  вл етс  способ получени  водорода из утлеводородной газовой смеси путем последовательного охлаждени  газовой смеси в теплообмепниках , с образованием газожидкостной смеси, разделени  последней в сепараторах и подачи ее жидких потоков с температурой от -120 до 130С на демета1Шзаш1ю выделени  жидкой метановой и газообразной метано-водородной фракций с использованием эффекта Джоул - Томсона 2.
Основной недостаток зтого способа - сравнительно невысока  степень чистоты получаемого водорода, равна  95-98 об.%.
0
Цель изобретени  - повышение степени чистоты получаемого водорода.
Цель достигаетс  тем, что в способе Полу чени  водорода из углеводородной газовой смеси, включающем последовательное охлаждение газовой смеси в теплообменниках с образованием газо-жидкостной смеси, разделение последней в сепараторах и подачу ее жидких потоков с температурой от -120 до 130 С на деметанизацию, вьщеление жидкой метановой и газообразной метано-водородной фракций , жидкую метановую фракцию нагревают до газообразного состо ни  и расшир ют в вихревой трубе с подачей образующихс  га
