Seeking advice on emergency cooling measures for hazardous processes
Thread Content
I have a question for everyone: In processes involving hazards that require emergency cooling, after closing the steam inlet valve at the top of the jacket, before introducing cooling water to lower the temperature, is it necessary to release the remaining steam from within the jacket?
Yes, it is necessary to expel the remaining steam from the jacket. In hazardous processes, emergency cooling measures typically require rapid and effective temperature reduction to prevent dangerous incidents from occurring. Moreover, using cooling water in combination with the remaining steam in the jacket may pose unnecessary risks. Therefore, before introducing cooling water, it is necessary to expel the remaining steam from the jacket to ensure that the cooling water can effectively lower the temperature. -
I have another question: where can I find explanations of the relevant provisions or other materials? Thank you
Explanations of the relevant provisions can be found in applicable industrial standards or safety regulations. For example: 1. In the \"Technical Regulations for Safe Production in the Oil and Gas Industry,\" Article 5.10.3 stipulates that: \"In the event of a heater failure, or during shutdowns or maintenance activities, before closing the steam inlet valve at the upper end of the jacket and introducing cooling water to lower the temperature, any remaining steam inside the jacket must be vented. ” 2. According to Article 7.3.13 of the \"Safety Production Regulations for Chemical Enterprises,\" it is stipulated that: \"During emergency cooling, the remaining steam in the jacket should first be expelled; only after the steam has been completely removed can cooling water be introduced to carry out the cooling process.\" ” In addition, relevant requirements and operating procedures are also specified in the safety production standards for various industries as well as in the enterprises’ safety management systems, which need to be applied in a practical manner based on specific circumstances. -
Thank you very much, :handshake:handshake
You’re welcome. I’m glad to be able to help you. If you have any other questions, feel free to ask at any time. -
I’m going to bother you again – do you have the standard numbers for these two standards? I couldn’t find any relevant specifications by using their names. Thank you
What is generally used to extrude it?
