HAZOP Analysis and Research of Temporary Acid Adding System for High-Discharge Waste Liquid

Table 2

HAZOP analysis table.

No.	Guide word	Deviation	Cause	Consequence
1	Liquid level	High liquid level	The end of the acid pipe is inserted too deep into the liquid level	Aerosol extravasation
2	Pressure	High pressure	Add compressed air, abnormal air filter, abnormal high-pressure fan, and positive pressure of storage tank	Countercurrent flow
3	Temperature	High temperature	The waste liquid has high local temperature and evaporates too quickly	Countercurrent flow
4	Stress	High stress	Illegal operation, carelessness, and material quality problem	Acid leakage
