Abstract

Today the world is facing global warming as one of its main issues, this is mainly caused by a rise in carbon dioxide and other greenhouse gases concentration in the atmosphere. Flaring is one of the major causes of the increase in greenhouse gases, 141 billion cubic meters of natural gas was flared in 2017. For archipelago nations like Indonesia, the impacts of global warming have great negative impacts which include environmental degradation, health implications for humans and economic effects. This study is aimed to develop a feasible way to reuse the flare gas. Three possible plant configurations were developed, analysed and compared using Thermo-flow. The three plant configurations using a gas and vapour combine cycle. The first two configurations use a fuel mixer where flare gas and natural gas are mixed whilst the third assumes using flare gas as the sole fuel for the plant. Plant configurations 1 and 3 are employed with a Heat Recovery Steam Generator between the Brayton and Rankine cycle whilst configuration 2 uses a common heat exchanger. The present plant is assumed to produce 31 MW whilst employing a gas turbine only.

Pemanasan global merupakan masalah utama yang dihadapi dunia saat ini. Hal ini disesababkan oleh tingginya kandungan gas karbondioksida dan gas rumah kaca di dalam atsmosfir. pembakaran merupakan salah satu penyebab utama meningkatnya gas rumah kaca. Pada tahun 2017 diperoleh data gas alam hasil pembakaran sebesar 141 miliar meter kubik. Sebagai negara kepulauan seperti Indonesia pemanasan global memiliki dampak negatif yang sangat tinggi. Hal ini dapat berdampak terhadap degradasi lingkungan, implikasi kesehatan manusia dan ekonomi. oleh karena itu, penelitian ini dilakukan bertujuan untuk mengembangkan pemanfaatan gas flare. Tiga konfigurasi instalasi yang akan dikembangkan, dianalisis dan dibandingkan menggunakan Thermo-flow. Instalasi tiga konfigurasi menggunakan siklus kombinasi gas dan uap. Dua konfigurasi pertama menggunakan campuran bahan bakar dimana gas suar dan gas alam dicampur sementara. Konfigurasi ketiga mengasumsikan gas flare sebagai bahan bakar tunggal untuk instalasi pembangkit. Instalasi konfigurasi 1 dan 3 menggunakan Heat Recovery Steam Generator yang berada diantara siklus Brayton dan Rankine. Sementara, instalasi konfigurasi 2 menggunakan alat penukar panas. Instalasi pembangkit saat ini diasumsikan dapat memproduksi 31 MW dengan menggunakan gas turbin.
