What issues should be considered when cooling the system with methanol? Put the liquid level of the ammonia cooler under automatic control to regulate the cooling rate at 1-2°C/h, with a maximum of no more than 5°C/h. At the same time, pay attention to the pump’s filter to prevent blockages. At the same time, nitrogen is continuously introduced to prevent a drop in pressure.

Put the liquid level of the ammonia (propylene) cooler under automatic control, with the cooling rate set at 1-2°C/h, not exceeding 5°C/h at most. At the same time, pay attention to the pump filters to prevent blockages. At the same time, nitrogen is continuously introduced to prevent a drop in pressure.
What issues should be considered when cooling the system with methanol? Answer: Set the liquid level of the ammonia cooler under automatic control to regulate the cooling rate at 1–2°C/h, with a maximum of 5°C/h. Additionally, pay attention to the pump’s filter to prevent blockages. At the same time, nitrogen is continuously introduced to prevent a drop in pressure.

1) The system is airtight, properly purged, and dried to specification； 2) The guide vanes are closed, and a blind plate is installed ； 3) The site should be thoroughly cleaned, and fire-fighting facilities must be in good condition. 4) All pressure controllers should be set to the specified pressure levels and operated in automatic mode; the pressurization rate for each system should not be too fast, and this should be controlled in accordance with relevant principles
Answer: Put the liquid level of the ammonia cooler under automatic control, adjusting the cooling rate to 1-2°C/hour, with a maximum of 5°C/hour. At the same time, pay attention to the pump’s filter to prevent blockages. At the same time, nitrogen is continuously introduced to prevent a drop in pressure.
Put the liquid level of the ammonia cooler under automatic control to regulate the cooling rate at 1-2 degrees per hour, with a maximum of 5 degrees per hour; at the same time, pay attention to the pump’s filter to prevent blockages. At the same time, nitrogen is continuously introduced to prevent a drop in pressure.
