:hug: Is steam good for testing the aeration in the coking desulfurization system? Is nitrogen better?
Generally, the nitrogen pressure is low; high sealing pressure requires steam!
The initial commissioning must be carried out in accordance with the commissioning procedures for construction projects, including purging, pressure testing, and leak testing. . . If it is a renovation and the amount of modification is small, steam can be used directly. . . The desulfurization of dry gas and liquefied gas, as well as the pressure in the acidic water system, are roughly on par with that of steam. . . :lol
The desulfurization system should be pressure-tested with nitrogen; especially in the alkali solution system, most gaskets are rubber gaskets, and steam can easily cause these rubber gaskets to age and get damaged
Generally, systems are tested for leaks using steam, as this facilitates further inspection for leaks and ensures that any issues can be identified easily. Although using steam to test leakiness in alkaline systems can cause rubber gaskets to age and get damaged, there should be no problems in the short term.
