Puissance cryogénique pour les terminaux de GNL.

Cryopower for LNG terminals.

Résumé

It is well known that LNG terminals require significant amount of heat to vaporize LNG and that lowering fuel gas consumption can appreciably reduce operating costs. LNG terminals also consume a significant amount of power, 20-30 MW for 1 Bscfd terminal, and there is an opportunity to efficiently generate power within the terminal by utilizing cold available from LNG thereby appreciably reducing operating costs and lowering emissions. The described Cryopower scheme uses an intermediate fluid Rankine cycle to generate power and provide sales gas at the specified temperature with a relatively small increase in terminal capital cost. This scheme may be utilized with any heat source available for vaporizing LNG. It has been shown that implementing Cryopower to generate power in lieu of importing power can result in savings of 10-15 MM USD/annum in operating costs. For a terminal that burns fuel gas to generate its own power, the savings may be even higher since the efficiency of power generation using this scheme is almost three times higher compared to a standard gas turbine generator. This paper describes various schemes and case studies performed on re-gasification projects where Cryopower adds significant value.
