Abstract
Radial inflow turbines (RIT), or turboexpanders, have become essential to the entire oil and gas industry, but also to specific applications in the realm of Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG) The RIT’s unique feature – the variable inlet guide vanes (vIGV) – renders the turboexpander as a variable geometry turbomachine, making it a viable and effective solution for variable load and flexible LNG production In the specific context of one case study – a mini-LNG plant in the United States – the authors discuss these characteristics of the RIT, while also describing its impact on plant efficiency, and generating monetary advantages for the operators
