What are the consequences of a flash vapor compressor tripping, and how should it be handled? Answer: The consequences of a flash vapor compressor tripping include: (1) the high flash tank may experience overpressure, and its liquid level is difficult to control, which affects system stability. ⑵Incomplete high-pressure flashing increases the load on the low-temperature flash and regeneration systems. ⑶In particular, it affects the purity of the decarburized low-flash gas CO2. Handling method: 1) Promptly open the vent valve to control the pressure in the high flash tank. 2) On-site handling at the original shutdown location of the compressor. 3) Start the backup compressor to determine the reason for the shutdown of the original compressor.

The consequences of a flash vapor compressor tripping include: (1) the high flash tank may experience overpressure, and it is difficult to control the liquid level in this tank, which affects system stability. ⑵Incomplete high-pressure flashing increases the load on the low-temperature flash and regeneration systems. ⑶In particular, it affects the purity of the decarburized low-flash gas CO2. Handling method: 1) Promptly open the vent valve to control the pressure in the high flash tank. 2) On-site handling at the original shutdown location of the compressor. 3) Start the backup compressor to determine the reason for the shutdown of the original compressor.
Consequence: The high flash tank may experience overpressure, and its liquid level is difficult to control, affecting system stability. Incomplete high-pressure flashing increases the load on the low-flash and regeneration systems. In particular, it affects the purity of the CO2 with a low flash point obtained through decarburization. Solution: Turn on PV1622 in a timely manner to properly control the pressure in the high-flash tank. Activate the backup unit to determine the reason for the shutdown of the original compressor.

The consequences of a flash vapor compressor tripping include: 1. The high flash tank may experience overpressure, and its liquid level becomes difficult to control, affecting system stability. 2 Incomplete high-pressure flashing increases the load on the low-temperature flash and regeneration systems. 3 Particularly, it affects the purity of the CO2 with a low flash point obtained through decarburization. Handling method: 1. Turn on PV1622 in a timely manner to control the pressure in the high-flash tank. 2. Start the backup unit to determine the reason for the shutdown of the original compressor.

Handling method: (1) Turn on the PV3220 in a timely manner to control the pressure in the high-flash tank. ⑵On-site, the originally running compressor was shut down manually. ⑶Start the backup pump and determine the reason for the shutdown of the original compressor.
Answer: The consequences of a flash vapor compressor tripping include: 1. The high flash tank may experience overpressure, and its liquid level is difficult to control, which affects system stability. 2. Incomplete high-pressure flashing increases the load on the low-temperature flash and regeneration systems. 3. Especially, it affects the purity of CO2 with a low flash point used for decarburization. Handling method: 1. Turn on the PV3220 in a timely manner to control the pressure in the high-flash tank. 2. On-site shutdown of the originally operating compressor. 3. Start the backup compressor to determine the reason for the shutdown of the original compressor.
