Abstract
A method for treating the formation of hydrates in a fluid system includes pumping a fluid at a substantially constant fluid flow rate through a hydrate removal system including a pressure modulator, communicating a vacuum pressure to a piece of subsea equipment from a pressure port of the pressure modulator, closing a valve in the hydrate removal system to cease the fluid flow through the hydrate removal system at the substantially constant fluid flow rate, and communicating a positive pressure greater than the vacuum pressure to the piece of subsea equipment in response to closing the valve of the hydrate removal system.
