Dear sea friends: There are newly built hydrogenation and hydrogen production units. How should the sequence in which these two sets of units are put into operation be determined when there is no external supply of hydrogen? It would be best to have an overview diagram. Thank you
It depends on what type of hydrogen production facility you have; if dry gas can be used for hydrogen production, then planning can be done based on the progress of the catalytic unit. After hydrogen is produced, it can be supplied to the hydrogenation unit, and the amount of hydrogen is very important in this regard. This needs to be handled in conjunction with the entire factory – it involves the inflow and outflow of materials as well as the activation of utility systems. The progress of one’s own equipment should be scheduled according to their progress, and it’s important to keep a good handle on these control points; time is relatively flexible on your end
Are there any existing hydrogen production facilities or something else for the new hydrogenation and hydrogen production units? This coordination is based on the schedule: for hydrogen production, it is first necessary to carry out furnace drying and heating, as well as catalyst installation, before operations can begin. During furnace drying and heating, the equipment’s instruments are checked, and any defects or leaks may need to be addressed, along with other final construction tasks. Generally, it takes 5 days for furnace drying and heating, and about 10 days for catalyst loading. If a plan is established, it should be followed strictly. However, catalyst loading is now done by external contractors, so it is necessary to communicate with them. As for the coordination diagram, it’s easy to create – one version for hydrogenation and another for hydrogen production. Determine when hydrogen is needed for hydrogenation, and then plan hydrogen production based on that timing; however, the preliminary work for hydrogen production can be carried out in advance. After the catalyst is fully reduced, the cycle is resumed in wait for feedstock to produce hydrogen, thus avoiding delays in progress. I hope this helps you. If you have any questions, feel free to contact me; we can discuss it!
It is best to control the transition point such that hydrogen production occurs at a time when hydrogenation is in the stage of pressure and temperature increase, thereby minimizing hydrogen venting
