Purge/sampling system for a vessel, the corresponding vessel and cleaning method using said purge/sampling system

摘要

The invention concerns a purge/sampling system for vessels, particularly for high temperature, high pressure vessels such as hydroconversion reactors used in refinery processes and operated in severe conditions. Such purge/sampling system comprises a purge/sampling line (16) equipped with a connector designed to be connected to the vessel (10), a first (18 and a second (20) flow regulation systems mounted in series on the purge/sampling line, wherein at least one injection line (22) is connected to the purge/sampling line between the first and the second flow regulation systems, said injection line comprising connecting means to a source of cleaning fluid (24) and at least one flow regulation device to control the flow of cleaning fluid through injection line and purge/sampling line The invention also concerns a vessel equipped with such a purge/sampling system, as well as a cleaning method using said purge/sampling system.
