Abstract

Compared to gaeous hydrogen, liquid hydrogen has approximately 1/800 volume, 800 times higher volumetric energy density at the same pressure, and the advantage of lower explosion risk and easier transportation than gaseous hydrogen. However, hydrogen liquefaction requires larger scale facility investment than simple compression storage method. Therefore, the research on energy-saving hydrogen liquefaction processes is highly necessary. In this study, helium/neon (mole ratio 80 : 20) refrigeration cycle was investigated as the main refrigeration process for hydrogen liquefaction. Process simulation for less energy consumption were carried out using PRO/II with PROVISION V10.2 of AVEVA. For hydrogen liquefaction, energy consumption was compared in three cases: Using a helium/neon refrigerant cycle, a SMR+helium/neon refrigerant cycle, and a C3-MR+helium/neon refrigerant cycle. As a result, the total power consumptions of compressors required to liquefy 1 kg of hydrogen are 16.3, 7.03 and 6.64 kWh, respectively. Therefore, it can be deduced that energy usage is greatly reduced in the hydrogen liquefaction process when the pre-cooling is performed using the SMR process or the C3MR process, which have already been commercialized, rather than using only the helium/neon refrigeration cycle for the hydrogen liquefaction process.

액체 수소는 기체 수소 부피의 약 1/800로 감소시킬 수 있어 동일 압력에서 기체 수소 대비 800배의 체적 에너지 밀도를 가지고 있고, 기체 수소에 비해 폭발 위험성이 낮고 수송이 용이하다는 장점이 있다. 하지만 수소 액화를 위해서는 대규모 시설투자가 필요하고, 단순 압축 저장방식에 비해 많은 에너지가 필요함으로써 경제성 문제가 수반된다. 따라서 에너지 절감형 수소액화공정 연구는 매우 중요하다고 볼 수 있다. 본 연구에서는 수소 액화를 위한 주요 공정으로 헬륨/네온(몰 비 80 : 20) 냉동사이클을 선정하고 화학공정모사기 AVEVA 사의 PRO/II ver. 10.2를 이용하여 공정모사 및 에너지 사용량을 도출하였다. 수소 액화를 위해 헬륨/네온 냉동사이클만을 사용하는 경우, SMR+헬륨/네온 냉동사이클을 사용하는 경우, C3-MR+헬륨/네온 냉동사이클을 사용하는 경우 에너지 사용량을 상호 비교하였다. 그 결과 수소 1 kg을 액화하는데 소요되는 압축기 총 소요 동력은 각각 16.3, 7.03, 6.64 kWh이었다. 헬륨/네온 냉동사이클만을 사용하는 것보다 상용화되어 있는 SMR 공정이나 C3-MR 공정을 사용하여 예냉하는 경우 에너지를 크게 절감할 수 있는 것을 확인하였다.
