Emergency Pressure Vent Products Energas Technologies is set to launch two new pressure vent products from Protectoseal, namely the Series 51700 hinged emergency pressure manhole cover vent and the Series 52600 emergency pressure/vacuum relief vent. While both provide emergency pressure relief for storage tanks exposed to external fire, the 52600 also provides vacuum relief. Since the sixth edition of API 2000 (API Standard for Venting Atmospheric and Low Pressure Storage Tanks) was launched, tank designers have had to consider the more stringent tank vacuum relief requirements. The required tank in-breathing rate is often much higher than the required out-breathing rate, such that the in-breathing rate determines the conservation vent’s size. According to Laetitia Botha, Energas Technologies product engineer, “The 51700 is designed to be installed on the manhole openings of tanks and helps to relieve large volumes of vapours beyond the capacity of the regular operating con-
servation vent. In comparison, the 52600 is designed to offer similar capacity emergency relief, but has the added benefit of offering vacuum relief. This vacuum relief capacity supplements the existing vacuum relief capacity of the conservation vent and as a result, a smaller conservation vent can be selected.” In emergency situations, such as an external fire, normal venting devices will be too small to relieve the amount of vapour given off. Similar to the Series 51700, the Series 52600 has a large capacity and is intended to relieve this emergency vapour flow. The unit’s integral vacuum vent gives the tank extra protection against possible collapse in the event of excessive vacuum in the vapour space. The maximum normal inbreathing rate of the tank can be shared between
the conservation vent and the vacuum portion of the emergency vent, resulting in a smaller conservation vent size. The 52600 has an air-cushioned seat with a flat, smooth FEP film diaphragm, supported on both sides of an annular channel, which forms a floating air seal. It is available in 16” (DN 400) through 24” (DN 600) sizes and is flanged to mate with flat face flanges, 150# ANSI, API (20” or 24” only) or DIN PN 16 bolting specifications. Other drilling patterns are also available upon special request. Energas Technologies, Laetitia Botha, Tel: (011) 397-6809, Email: laetitia@energas.co.za, www.energas.co.za
