- Abstract
A study is conducted on the technology and process of constructing pipeline hydrogen supply station of refinery enterprises relying on by-product hydrogen resources. Optimization design measures have been proposed to simplify process, save investment and reduce energy consumption. Research has found that after cancelling the hydrogen storage bottle group, the control cabinet system, and pre-cooling process of the hydrogenation dispenser in the hydrogen station, it can still meet the safety requirements that the temperature inside the on-board hydrogen cylinder should not exceed 85 °C during filling hydrogen-powered vehicles, and at the same time meet the requirements of hydrogen filling efficiency and better user experience. Compared to the 2,000 kg per 12 hours pipeline hydrogen supply station with the same pressure grade and function in the conventional typical process, the optimized 3,000 kg per 12 hours pipeline hydrogen supply station with 35 MPa pressure grade reduces the investment in major equipment per unit of hydrogen filling scale by more than 50%, decreases the installed power from 1,025 kW to 630 kW, a reduction of 38.5%; the major energy consumption reduces from 6.15 kW • h/kg to 2.52 kW • h/kg, which is more than 50%.
