As part of a polypropylene plant project by theKorean-funded Hyosung Vina Chemicals company, the storage cavern has been builtat a depth of between more than 100m to nearly 200m above sea level, with 95percent of its workload completed.
Engineer Pham Thi Hong, an operator of the facility, saidthe facility lies under a layer of hard rock and is designed in an egg-shapedform so that the pressure is distributed evenly. Meanwhile, its other technicalfactors will keep LPG from leaking out, she added.
Wie Chol Ryang, chief operator of the undergroundconstruction, underscored its absolute safety against earthquakes, tsunamis, orvolcanoes.
He said its life span is 50 years, noting that anunderground storage facility costs less than the one built on the ground andoffers better land use efficiency.
In addition to the cavern, to serve the plant, Hyosung Vinahas built 10 gas tanks with a capacity of 4,000 tonnes each, the largest oftheir kind worldwide.
The project also includes a fractionation tower of nearly120m high and 10m in diameter, making it the tallest and largest in the world./.
