Establish new health protection distance standards for ammonia synthesis combined with methanol production?
Thread Content
Our company needs to relocate to the newly built chemical industrial park due to a change in the location of the existing chemical park in the city. During the project approval and environmental impact assessment processes, the officials in charge and environmental assessment experts stated that the health protection distance for this project should be determined according to the standards for coal-based gas production (the required health protection distance for coal-based gas is 2200 meters). They said that if only ammonia synthesis were carried out, the safety and health protection distance could be set according to the standards for ammonia synthesis projects (the required distance for ammonia synthesis is 900 meters). However, as long as methanol production is involved, the standards for coal-based gas production must be applied. Despite explaining that methanol production is merely a by-product of ammonia synthesis, our arguments were not accepted. Do any of you experts know the specific provisions of the latest environmental protection laws and regulations regarding this matter? Please share your insights. Or rather, how to handle similar situations?
Give it a push. Awaiting guidance from the experts.

It is necessary to consult a Class A chemical engineering design institute to determine whether the production of gas from coal should comply with GBT17222-2012 regarding the sanitary protection distances for gas stations or gas compression stations: when 100 tons of gas are stored per day, the protection distance should be 2200 meters or less. The required distances vary significantly depending on the storage volume of methanol and liquid ammonia.
We produce methanol as a by-product of ammonia synthesis. Isn’t the standard for ammonia synthesis GB11666.1-2012? Design institutes, EIA preparation agencies, and environmental protection departments all have different opinions. Some say it should follow the standards for synthetic ammonia, while others say it should follow the standards for gas produced from coal: L
Let me try again: Where is God Lord L? :o
Try once a day, waiting for the expert: L:L:L:L
There are indeed problems with the formulation of this standard, but once it becomes a national standard, it must be implemented.
For an explanation, you can only turn to the standard compiler. I participated in a project where they explained it in terms of non-flat areas.
