[0002] With the popularity of buried pipelines, ensuring the smooth, safe and efficient operation of buried pipelines has become a long-term and important task.

Only under accident conditions, the leakage of decarbonization and desulfurization absorbent may cause pollution to the soil and groundwater environment along the line. The amount of decarbonization and desulfurization absorbent leaked underground due to pipeline leakage accidents is limited. If it is handled promptly and properly, the impact on the surrounding environment can be effectively controlled.
