Industrial process for conversion of natural gas to olefins (petrochemical feedstock).
"What makes GTO particularly appealing is its potential to use natural gas from remote fields that doesn't have easy access to world markets - gas that otherwise would be difficult to sell."
A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (e.g. 1200 V AC) semiconductor device. It was invented by General Electric. GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead.
