Abstract

Proses pirolisis sejatinya adalah proses pembakaran tidak langsung atau proses pemanasan terhadap biomassa pada suhu tinggi (250 – 650) oC. Proses pirolisa menghasilkan uap panas atau sering disebut dengan uap pirolisis ataupun volatiles. Uap pirolisis akan berubah wujud menjadi cairan (condensate) bila didinginkan. Selain menghasilkan cairan juga menghasilkan gas yang dapat terbakar (producer gas). Tujuan kajian ini adalah mendesain dan menguji secara teoritis alat kondensasi asap pirolisis dari biomassa. Untuk proses kondensasi dibutuhkan alat perpindahan panas (heat exchanger) dimana panas laten yang dimiliki uap pirolisis harus segera dibuang (reject) menggunakan cairan pendingin (coolant) agar suhunya menurun hingga mendekati suhu saturasinya sehingga proses kondensasi dapat berlangsung. Kondensor tabung-koil spiral vertical (shell-coiled tubes) dapat menjadi solusi untuk masalah kondensasi uap panas pirolisis biomassa bila direncanakan dengan tepat. Kondensor jenis ini sangat simple dan mudah dalam hal maintenance. Merencanakan kondensor tipe tabung-koil berdasarkan analisis hidrodinamik membawa para perancang (engineer) semakin dekat dengan alat pendingin uap pirolisis dengan kinerja yang tinggi. Dari hasil analisis bahwa penambahan jumlah gulungan koil dapat meningkatkan efektifitas pendinginan.

Abstract

Global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes. This report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security.
