Membrane filtration is an integral part of many industrial processes, as it is often more environmentally sustainable and cost-effective than other separation technologies
At about 5:30 a.m. on Nov. 19, 1984, there was a major fire and a series of explosions at a liquefied petroleum gas (LPG) storage and distribution terminal at San Juan Ixhuatepec, Mexico City, Mexico. There were over 500 fatalities, about 7,000 injuries, 200,000 people were evacuated, and the terminal was destroyed. The blasts were recorded on a seismometer 20 km (12.4 miles) away. Most of the injuries and fatalities were in the surrounding community — people were living as close as 130 m (425 ft) from the terminal. The cause of the accident could not be definitively established because of the destruction of the facilities and absence of witness reports.
