The waste of pulp and paper industry in the form of Black Liquor still contained a large amount of lignin (12-46%). The high lignin content had the potential to make Sodium Ligno Sulfonate (SLS) Surfactants by reacting Lignin with Sodium Bisulfite. Isolation of Lignin From Black Liquor was carried out at room temperature of 30°C, using sulfuric acid (H2SO4) and 1N NaOH. The purpose of this stu…

Pabrik pembuatan LPG tempat penelitian ini berlangsung dioperasikan oleh PT. ODIRA ENERJI PERSADA, terletak di lapangan minyak Babelan, Bekasi-Jakarta Timur. Permasalahan yang ada di pabrik tersebut yakni zat penyerap uap air (molekuler sieve) di unit pengering gas, setiap 1 tahun beroperasi harus diganti baru, dikarenakan beda tekanan gas masuk dan keluar (pressure drop) unit pengering lebih b…
