When RGC speed is increased in a DHDT unit then how does recycle gas flow increase even if the total high pressure (HP) loop is a closed loop?
Does the recycle gas velocity increase, or the travelling time of recycle gas decrease, due to increased pressure difference in the RGC suction and the discharge pressure?

That’s exactly right. The vapour velocity in the high pressure loop increases, driven by the increase in RGC discharge pressure.
