Frequently Asked Questions

What does a turbo expander do?

A turbo expander converts high-pressure gas into work, often powering a compressor or generator. It does this by expanding the gas through a turbine, producing energy that can be harnessed for various applications.

What is the difference between a gas turbine and a turbo expander?

The main difference between a gas turbine and a turbo expander is their primary function: turbines generate power, while turbo expanders reduce pressure and generate power. This distinction lies in their design and application, with turbines often used for power generation and turbo expanders used for pressure reduction.

What is the difference between a turbo expander and a JT valve?

A turbo expander extracts work from gas expansion via a turbine, whereas a JT valve achieves a constant enthalpy expansion adiabatically without work output. In essence, a turbo expander is a more efficient version of a JT valve.

What is the cryogenic turbo expander process?

The cryogenic turbo expander process is a method that uses a turboexpander to produce refrigeration and achieve very low temperatures. This process enables the recovery of valuable light components, such as ethane and propane.

What is the pressure ratio of a turboexpander?

A typical single-stage turboexpander has a pressure ratio of 4:1, but it can range up to 14:1 depending on the process. This significant pressure drop enables energy removal and cryogenic temperature reduction.
