Abstract


Industri kimia dan juga termasuk di dalamnya, industri semen, menghadapi tantangan untuk dapat terus melakukan perbaikan proses untuk melakukan efisiensi sumber daya dan meminimalkan beban pencemaran ke lingkungan. Salah satu hal yang penting di industri semen adalah kandungan SO2 pada emisinya. Kandungan emisi ditentukan oleh proses pengolahan gas, yang dilakukan dengan penyemprotan air di gas conditioning tower (GCT) dan bag filter sebelum dikeluarkan ke lingkungan melalui cerobong. Di sisi lain, konsumsi air di GCT merupakan salah satu titik penggunaan air yang tertinggi di industri semen. Studi ini bertujuan untuk menganalisis efisiensi penggunaan air di GCT dengan menggunakan seven tools mulai dari analisis masalah hingga pembuatan usulan standard operating procedure (SOP) baru. Dari analisis ini didapatkan bahwa tergantung pada kadar SO2 dan SO3 di emisi dan bahan baku, maka dapat dilakukan pengendalian temperatur inlet bag filter yang selanjutnya akan mengendalikan volum air di GCT. Hasil pengembangan/inovasi ini menunjukkan bahwa SOP baru dapat menghemat air di GCT secara signifikan.
