Is it necessary to install an emergency shut-off valve at the outlet of a 100m3 horizontal liquid ammonia tank?
It needs to be set, as the medium is liquid ammonia
Interim Provisions on the Supervision and Management of Major Hazard Sources of Hazardous Chemicals** Order No. 40 of the State Administration for Work Safety: (3) Install emergency shut-off devices for key facilities within major hazard sources, such as toxic gases, highly toxic liquids, and flammable gases； For facilities handling toxic gases, emergency devices for dealing with leaks must be installed. For Class 1 or Class 2 major hazard sources involving toxic gases, liquefied gases, or highly toxic liquids, an independent Safety Instrumented System (SIS) is required ；
The required petrochemical regulations also specify this; for liquid ammonia, liquefied hydrocarbons serve as a reference
Of course it is needed. Flammable, explosive, toxic, and harmful liquids all require the installation of quick shut-off devices.
Installation is required; the hazards of liquid ammonia are to be treated on par with those of liquid hydrocarbons
