Abstract:
본 발명은 수소 중에 함유된 불순물인 일산화탄소, 이산화탄소, 메탄, 산소, 질소, 아르곤, 수분 등을 희토류계 합금의 상온에서 수소만의 흡장특성을 이용하여 불순물가스와 분리, 제거하여 고순도의 수소(99.999%이상)를 연속적으로 생산하기 위한 장치로서 고순도 수소의 생산을 위한 소비에너지를 절감하고, 저렴한 분리 매체를 이용하므로서 고순도 수소의 생산비용을 절감할 수 있는 장치이다. 또한 희토류계 합금은 수소흡장시 발열반응을, 수소방출시 흡열반응을 일으키는데 이때 적절한 열교환이 이루어지지 않으면 합금의 수소흡장, 수소방출 능력이 현저히 저하하므로 정제탑 내의 열교환이 매우 중요하다. 본 장치에서는 이러한 열교환을 위해 정제탑내에 적절한 열교환 핀을 설치 하였으며, 원료수소 흡장시 냉수를 수소흡장탑(정제탑1 또는 정제탑2)에 보내고 이 수소 흡장탑에서 나온 열매를 회수하여 수소 방출중인 수소방출탑(정제탑2 또는 정제탑1)에 보내어 흡열반응을 충족시킴으로서 시스템 자체에서 발생하는 열원을 이용한 열교환 방식을 채택하여 효율을 극대화 하였다.
