Regarding the layout of compressors in the liquid ammonia tank area
Thread Content
The company has decided to use an ammonia compressor for unloading liquid ammonia from tank trucks, but where should the ammonia compressor be installed? I checked the specifications, and there are no requirements regarding fire separation distances for compressors and ammonia tanks; it only states that compressors should be placed near the equipment being pumped. Are there any distance requirements between the ammonia compressor, the ammonia tank, and the ammonia pump?
Refer to Petrochemical Code Table 5.2.1 or Building Code 4.4.2
The required distance from the ammonia tank is 15 meters； The distance from the pump should be sufficient for proper operation; generally, such compressors are installed in the pump area.
The question raised by the poster is: what is the size of the ammonia tank? It can be determined in accordance with Table 5.2.1 of the petrochemical regulations. Regarding the distance from the pump, it is specified that for ammonia tanks with a capacity of less than 1000 cubic meters, the distance from the pump can be 11.25 meters.
It is specified in the \"Code for Fire Protection Design of Petrochemical Industries\" GB50160-2008; the table includes distance requirements.
Hello, OP – have the distances between the ammonia compressor and the spherical tank, as well as between the pumps and the spherical tank, been determined? Could you please mention which standard was used as a reference?
Hello, what standards are you referring to? Could you specify which one?
Hello, is the distance between liquid ammonia spheres and pumps as well as compressors determined based on liquefied hydrocarbons or according to Class B liquids?
I suggest you carefully consider the requirement in GB50160-2008, where 5.3.4 stipulates that it should not be less than 15 meters. Just press liquefied hydrocarbons.
That’s right; try to make it as large as possible. I’d like to ask what the differences are between the tanks used in this device and those used in the field of storage and transportation Could you give a detailed introduction? I built two 1,000-liter liquid ammonia storage tanks. Do these tanks fall under the category of storage tanks used in the facility, or do they belong to the category of tanks used for storage and transportation?
