Sambutan umum sekaligus pembukaan webinar series geothermal<\/em> 10 edisi KITS-ON 36 oleh perwakilan Ikatan Alumni Institut Teknologi Sepuluh Nopember (ITS) di Luar Negeri (IKA-ITS LN)<\/figcaption><\/figure>\n

Kampus ITS, ITS News<\/strong> \u2013 Produksi energi panas bumi menjadi tantangan yang besar ketika fluida kimia geotermal mengakibatkan korosi dan <\/span>scaling <\/span><\/i>pada bahan konstruksi produksi. Menyadari permasalahan ini, Ikatan Alumni Institut Teknologi Sepuluh Nopember (ITS) di Luar Negeri (IKA-ITS LN) bekerjasama dengan Pusat Penelitian Energi Berkelanjutan ITS mengadakan <\/span>webinar series<\/span><\/i> yang bertajuk <\/span>Scale Pervention Program In Geothermal Industry by DSI<\/span><\/i>, Sabtu (01\/05)<\/span>.<\/p><\/blockquote>\n

Dalam materi yang dibawakan oleh Regional Manager South East Asia NEUCHEMIE, Nur Choiri Amin, dijelaskan bahwa fluida kimia geotermal memiliki komposisi keasaman yang berisi sulfur dan asam halogen yang aktif mengkorosi banyak campuran logam sehingga akan menyebabkan kerugian pada produksi energi panas bumi. \u201cKerugiannya berupa penurunan kapasitas produksi hingga peningkatan biaya perawatan,\u201d jelasnya.<\/span><\/p>\n

Lebih lanjut, Choiri memaparkan bahwa ada banyak jenis korosi yang terjadi pada sistem geotermal, salah satunya korosi seragam atau erosi. Korosi ini terjadi karena efek mekanik pada logam, misalnya abrasi dan gesekan pada sistem. Logam yang mengalami korosi akan menimbulkan bagian-bagian yang kasar dan tajam.<\/span><\/p>\n

Pemaparan materi oleh Nur Choiri Amin, Regional Manager South East Asia saat menjelaskan kegiatan-kegaiatan oleh divisi geotermal perusahaan NEUCHEMIE yang berkaitan dengan korosi dan scaling<\/em><\/figcaption><\/figure>\n

Ia juga menyebutkan, aliran fluida geotermal yang sangat cepat dapat merusak permukaan logam dan lapisan pelindung alat sehingga meningkatnya laju korosi. \u201cRusaknya lapisan ini akibat serangan korosi secara berkelanjutan dapat membuat pipa menjadi cekungan,\u201d ungkapnya.<\/span><\/p>\n

Menurutnya, aliran fluida geotermal yang kontak langsung dengan hidrogen ini merupakan masalah utama terbentuknya korosi dan lambat laun akan menimbulkan <\/span>scaling<\/span><\/i>. <\/span>Scaling<\/span><\/i> sendiri merupakan kerak yang terbentuk oleh senyawa kimia silika, kalsite dan terkadang sulfid,<\/span> sedangkan korosi adalah penyebab kedua pembentukan <\/span>scale<\/span><\/i>. \u201cPermasalahan ini sangat penting karena akan merugikan pada efisiensi pompa geotermal,\u201d ujar pria berkacamata ini.<\/span><\/p>\n

\"\"
Pembahasan masalah pembentukan korosi dan scaling<\/em> pada pipa-pipa geotermal dan dampak yang diakibatkan dari kedua permasalahan tersebut<\/figcaption><\/figure>\n

Mengaitkan korosi dan <\/span>scaling<\/span><\/i>, pria yang memaparkan materinya dari Turki ini mengungkapkan karena dua hal ini sangat berhubungan erat, maka tidak ada tes atau indeks yang cocok untuk dijadikan indikator untuk kedua permasalahan ini. Sampai saat ini hanya dapat menggunakan indikator nilai pH semikuantitatif dari aliran fluida geotermal dengan melihat kecenderungan air yang dapat menyebabkan<\/span> scaling<\/span><\/i>.<\/span><\/p>\n

Pada akhir pemaparan, pria yang akrab dipanggil Choiri ini menjelaskan bahwa sudah ada pertimbangan untuk menggunakan indikator saturasi langelier, tetapi indeks kejenuhan indikator ini tidak bisa digunakan untuk memprediksi korosi. \u201cSaya berharap segera dibuatnya indikator untuk menganalisis kedua potensi korosi dan scaling,\u201d harap Choiri mengakhiri webinar<\/span>.
