Abstract

In this study, a new combined power system was proposed for the Marmara Ereglisi receiver terminal and the power generation during the evaporation of liquefied natural gas (LNG) was investigated. The combined power system consists of an open Brayton cycle (BC), a closed Rankine cycle (HRC) operating at high temperatures, and a closed Rankine cycle (LRC) operating at low temperatures. In the combined power system, an optimum value for the LRC condenser inlet pressure was found to be 150.7 kPa. The total power consumed, including LNG pumps in the system was found to be 193.413 MW and 291.321MW net power produced from the system.

LNG’nin Soğuk Enerjisini Kullanan Yeni Bir Birleşik Güç Sistemin Termodinamik Analizi

Abstract

Bu çalışmada Marmara Ereğlisi alım terminali için yeni bir birleşik güç sistemi önerilmiştir ve sıvılaştırılmış doğalgazın (LNG) buharlaşması esnasındaki güç oluşumu araştırılmıştır. Birleşik güç sistemi bir açık Brayton çevrimi (BC), yüksek sıcaklıklarda çalışan bir kapalı Rankine çevrimi (HRC) ve düşük sıcaklıklarda çalışan bir kapalı Rankine çevriminden (LRC) oluşmaktadır. Bileşik güç sisteminde LRC kondenser giriş basıncı için optimum değer 150.7 kPa olarak bulunmuştur. Sistemdeki LNG pompaları da dahil harcanan toplam güç 193.413 MW ve sistemden üretilen net güç 291.321 MW olarak bulunmuştur.
