Optimum liquefaction fraction for boil-off gas reliquefaction system of semi-pressurized liquid CO2 carriers based on economic evaluation

Dimethyl ether/CO2 – a hitherto underestimated H2 storage cycle

“…Literature suggests boil-off losses of 0.017% per day for the DME transport 60 while CO 2 losses are slightly higher with 0.12-0.15% per day. 58,59 To evaluate the harm of BOG and potential further losses during the transport and storage cycle on the climate, we have additionally given the global warming potential of the vectors. Here, DME shows a moderate value of 0.3 CO 2 -equiv.…”

Numerical Model of Heat Diffusion and Evaporation by LNG Leakage at Membrane Insulation

“…이 러한 이유로 인하여 많은 연구들 (Caps and Fricke, 2000;Choi et al, 2013;Demharter, 1998;Presley and Christensen, 1997)이 BOR을 낮출 수 있는 단열 구조를 제안하거나, BOR 값을 만족 하기 위한 재액화 (Chu et al, 2012;Li et al, 2012;Shin and Lee, 2009) 방법을 제시하고 있다. 또한, 화물창의 안전성 확보 를 위한 구조 강도 평가에 관한 연구는 여러 문헌과 기술 자료 로부터 사례를 찾아 볼 수 있다 (Hwang et al, 2012;Ito et al, 2008;Lee et al, 2011b;Nho et al, 2012).…”

Computational study of LNG evaporation and heat diffusion through a LNG cargo tank membrane

“…Many research efforts have been given to novel insulation materials and structures at low temperatures (Presley and Christensen, 1997;Demharter, 1998;Caps and Fricke, 2000;Choi et al, 2013;Zakaria et al, 2013) and reliquefaction systems (Shin and Lee, 2009;Chu et al, 2012;Li et al, 2012) to meet the demands of lower BOR. Since the BOR is proportional to the heat transfer amount from ambient through cargo containment systems (CCS), the thermal properties and the structure of the CCS insulation system are important.…”
