Handling of solvent deasphalting accidents
Thread Content
I would like to ask the experts: what should be done if there is an uncontrolled solvent leak in a high-pressure system (by \"uncontrolled\" I mean it’s not possible to locate the source of the leak, and the leakage is severe)? An emergency shutdown of the furnace is definitely necessary, but what about the hundreds of tons of solvent in the system? Directly into the flare stack?
Recommendation: 1. Shut down the device urgently, cut off feed and discharge, and reduce temperature and pressure； 2. Turn on the fire-fighting water at the leakage area to dilute the leaking solvent ； 3. Try to cut off from the nearest point to the leakage site in order to isolate the source of the leak. 4. Gas detection and fire protection. 5. Open flames are prohibited on site ； 6. Unrelated personnel and vehicles are prohibited from entering the site. 7. As appropriate, activate the interlock to depressurize the device’s high-pressure solvent system. The above measures can be carried out simultaneously. The goal is to ensure the safety of personnel and equipment, and to resume production as soon as possible. For exchange and reference.
Thank you, that’s great advice! Could you explain in detail what the interlock for point 7 entails, namely the interlock that causes the high-pressure solvent system of the device to release pressure? High-pressure systems have high pressures and few isolation valves, making it difficult to handle accidents caused by high-pressure solvent leaks.
Interlocks include: 1. Emergency pressure relief valve ； 2. Cut off the extractor feed ； 3. Cut off the low-pressure solvent supply and increase the pressure.
Are these emergency stop interlocks?
A part. Which factory do you work for? Let’s exchange more ideas, buddy.
