Safety protection distance for air separation units
Thread Content
Question: For a single air separation unit with a capacity of 3500 m3/h and two liquid storage tanks with a capacity of 800 m3 each, what are the specific requirements regarding hygiene protection distances and safety distances? Those who have experience in conducting safety assessments and environmental impact evaluations, please offer some guidance. Thank you.
What liquid is in the liquid storage tank? How can it be analyzed without knowing that?
I haven’t carried out safety assessments, but I believe that those who do so also act in accordance with relevant laws and regulations. You might as well take a look at \"Hygienic Protection Distances for Petrochemical Enterprises – SH 3093-1999\" at http://bbs.hcbbs.com/thread-104146-1-5.html and the \"Code for Fire Protection Design of Petrochemical Enterprises\" at http://bbs.hcbbs.com/viewthread.php?tid=183527&highlight=%CA%AF%D3%CD%BB%AF%B9%A4%C6%F3%D2%B5%B7%C0%BB%F0%B9%E6%B7%B6.
The storage tanks in the air separation unit are those for liquid oxygen and liquid nitrogen.
Air separation units **do not have specific requirements regarding hygiene protection distances; this depends on the provisions set out in the environmental impact assessment.** The safety distance refers primarily to the fire separation distance; storage tanks for liquid oxygen with a capacity of 800 m³ require a relatively large fire separation distance. The GB 16912-1997 \"Safety Technical Regulations for Oxygen and Related Gases\" specifies these requirements clearly, so it is advisable for the person in question to carefully review those regulations. The \"Safety Technical Regulations for Oxygen and Related Gases\" are available for download online.
Design codes for oxygen stations: GB 50030-91 and GB 16912-1997 Safety technical regulations for oxygen and related gases. ⑨ For liquid oxygen storage tanks with a volume of no more than 3 m3, the fire separation distance from the building in which they are used can be reduced to 10 m.
