Consultation on how to achieve unit pressure drop without power consumption

Hello, if I want to reduce the pressure of stream (high pressure) of the reactor outlet to one atm, could I consult you what unit can I use? If the Tank is used, it seems that the pressure drop cannot be achieved, and if the pump is used, it seems that the pump will consume electricity, but the pressure drop can be achieved by opening the reactor in actual production, and no power consumption is required. Could I ask you how to simulate this process?

Thanks for your help. Wish you a good day.

The issue names no files, tests, or entry points. Start by reviewing the repository's process-simulation documentation and existing unit models for pressure reduction, then determine whether the requested operation is already supported; done would be a documented, project-specific simulation approach.
