Carbon Neutral Solutions

Overview

Cryogenic power generation is a type of power generation which harnesses the expansion energy generated though the phase transition between the liquid and vapor of an intermediate heating medium as a working fluid. By adopting this technology, the cold energy of LNG which was previously wasted in the form of discharged seawater, is recovered and utilized to generate electricity.

Features

• Zero Emissions - No fuel consumption is needed.
• Improved energy efficiency by recovering wasted cold energy.
• Easy operation and maintenance
• Compact Footprint

Process

• The Intermediate Fluid is introduced to the Intermediate Fluid LNG Vaporizer (Tri-Ex) where the Intermediate Fluid is vaporized by seawater, causing its expansion which rotates the expansion turbine and generates electricity.
• The vapor out of the turbine then flows into the Intermediate Fluid condenser, which also functions as an LNG vaporizer, where it is condensed by the extremely cold LNG while the LNG is introduced and vaporized. The natural gas is then heated by seawater again before it is delivered to the gas transmission line.
• The liquid Intermediate Fluid is pressurized by the circulation pump and reintroduced into vaporizer, where Intermediate Fluid is vaporized into vapor to rotate the turbine. All these steps constitute one cycle.
