Abstract
A method of blowing out debris or sand from a separation device comprises opening a second valve assembly such that the second valve assembly is not exposed to pressurized fluid from the separation device when opening. A first valve assembly is opened, wherein the first valve assembly is downstream of the separation device and upstream of the second valve assembly. Debris or sand from the separation device is blown through the first and second valve assemblies, and through a choke port of a third valve assembly. A method of closing fluid flow through a high integrity pressure protection system comprises closing a primary valve in response to detecting the over pressurization of fluid in the fluid line, and closing at least one secondary valve in response to detecting the closing of the primary valve.
