Abstract

Package boiler (PB) is a utility unit essential for producing steam by heating Boiler Feed Water (BFW) through the combustion of natural gas with air. Therefore, this study aimed to investigate the effect of heat loss on PB efficiency. To achieve this, direct and indirect methods were adopted, with data collected between 4 July and 29 August 2023. The results showed that PB efficiency in the fertilizer industry during this period ranged from 76.06% to 80.71%. On August 29, 2023, under optimal conditions, an efficiency of 80.71% was achieved, while a significant drop to 65.44% occurred during the 6th week on August 8, 2023, due to low oxygen (O2) levels. Flue gas analysis on August 29, 2023, obtained 3.64% excess O2, 11.17% carbon dioxide (CO2), and 0.04% carbon monoxide (CO). PB performance was influenced by heat loss from the dry flue gas, hydrogen (H2) content on flue gas, moisture in air and fuel, incomplete combustion, as well as radiation and convection phenomena.

Abstract

Most waste from palm oil processing can be repurposed, such as using palm fibre waste to create activated charcoal. This study aimed to assess the effectiveness of activated charcoal, produced by activating palm fibre with H₃PO₄, in removing silica from boiler output water. The production process involved pyrolysis at 200ºC for 2.5 hours. A completely randomized design was employed to test the effects of different H₃PO₄ concentration (with 1 to 2 M) and reaction times (30, 60, and 90 min). Results revealed that the moisture content of the activated charcoal ranged from 1.96% to 2.42%, ash content from 9.82% to 21.63%, and iodine adsorption from 366.43 to 457.87 mg/g. The highest silica adsorption capacity (3.5 g/g) was achieved with 2 M H₃PO₄ for 90 min. This indicates that palm fibre-derived activated charcoal is effective for silica removal, highlighting it is potential for enhancing environmental sustainability in industrial sector.

Abstract

Used pots and beverage cans are good sources of aluminum-rich raw materials for the synthesis of potassium aluminum sulfate (KAl(SO4)2), a solid coagulant. The synthesis process includes preparation, dissolution, extraction, sedimentation, and drying. Therefore, this research aimed to determine the characteristics of KAl(SO4)2 synthesized from aluminum pots and beverage cans waste, adjusted to the quality requirements of commercial KAl(SO4)2 according to SNI 06-2102-1991 standard. The materials used were aluminum pots, as well as a mixture of pots and beverage cans, with varying concentrations of 20%, 30%, and 40% KOH solvent. The synthesis results, characterized by XRF (X-ray fluorescence), showed an Al content of 0.001-3%. In addition, the results of the data analysis, adapted to SNI 06-2102-1991 standard for potassium aluminum sulfate, indicated that the synthesis met the required parameters for water-insoluble parts, Fe, Pb, and As, and Al2SO3, which was close to the quality requirements.

Abstract

Textile industry wastewater is a very complex pollutant-containing waste with high dye intensity, requiring proper and appropriate treatment. Membrane technology is one of the appropriate methods for treating textile wastewater due to several advantages such as environmentally friendly and biopolymer-based processing. Therefore, this review aimed to determine the effectiveness of membrane technology and provide information regarding the appropriate treatment of textile wastewater. The articles subjected to review were obtained from several journal sources such as ScienceDirect, Elsevier, Springer, Google Scholar, and national journals. The results showed that several membranes had been used in textile wastewater treatment, such as PTFE (Polytetrafluoroethylene), PES (Polyethersulfone), Polysulfone-Polyvinyl Pyrrolidone Blend Polymer Composite Membrane, CA (Cellulose Acetate), Cellulose Membrane of Sargassum Sp., polysulfone (PSF), Bacterial Cellulose Membrane, and cellulose acetate propionate (CAP). Furthermore, membrane technology was found to reduce dye pollutants in textile wastewater with the highest coefficient value of approximately 97%.
