Abstract: The traditional split fire-resistance breathing valve and emergency pressure relief valve are unreasonable in structure, inherently unsafe, and have a large leakage, which cannot meet the increasingly stringent safety and environmental protection requirements. This paper introduces valve and emergency relief valve which are of reasonable structure with intrinsic safety and good sealing performance. This can meet the most stringent current international and domestic environmental protection standards. The highly efficient new integrated fire retardant breathing valve and emergency relief valve have achieved good results in practical application in tank farms. The application of them can reduce the VOCs emissions of the tank farms greatly and save a lot of nitrogen blanketing gas.

Key words: tank farm, highly efficient new integrated fire retardant breathing valve, emergency relief valve, volatile organic compounds/VOCs, discharge in compliance with environmental protection standards, energy- saving and emission reduction
