Cryogenics technology and expertise are becoming increasingly important as South Africa plans on leaning into using liquefied natural gas (LNG) as a major source of energy, Howden senior application engineer Pieter Swart said at mine ventilation solutions developer Howden’s Technology Day, hosted at Mintek, in Johannesburg on April 17. Cryogenics also plays a crucial role in the handling of helium, which plays a critical role in scientific research, medical technology, high-tech manufacturing, space exploration and national defence initiatives, he added.
