An Outlook on Tar Abatement, Carbon Capture and its Utilization for a Clean Gasification Process

The presence of oil and gas production fields, oil refineries, cement plants, and coalfired power plants situated close to each other supports the program for zero CO2 emissions through Carbon Capture, Utilization, and Storage (CCUS) for Enhanced Oil Recovery (EOR). This study aims to investigate the potential of depleted fields in the North West Java Basin as the target for CCUS-EOR in fulfilling the zero CO2 emission program and boosting oil production. The study uses oil and gas field data to evaluate the CCUS potential both qualitatively and quantitatively. The Geographic Information System was applied through a clustering method with a 50 km and 100 km buffer from CO2 emission sources. The calculation of CO2 for EOR purposes with a 50 km buffer radius is 287.504 million tons, which could result in a 575.009 million stock tank barrel (STB) increase in oil production in the case of immiscible injection and 379.506 million tons for an increase of about 1.150 billion STB of oil production in the case of miscible injection. For a 100 km buffer radius, 632.541 million tons of CO2 is required to increase 1.265 billion STB of oil production in the case of immiscible injection and 834.955 million tons of CO2 for an increase of 2.530 billion STB of oil production in the case of miscible injection. These results are expected to be implemented as part of the program to reach the goal of producing 1 million barrels of oil per day by 2030 and achieving net zero emissions by 2060.

“…Additionally, the sea level has increased at an average annual rate of 1-2 mm over this time period 3) . Continuous increases in the concentration of GHGs in the atmosphere are anticipated to result in climate change, which would alter ecosystems dramatically, threatening livelihoods, economic activity, living conditions, and human health 4,5) . Materials management, which encompasses the production, consumption, and disposal of materials, goods, and infrastructure, is responsible for a sizable portion of global GHG emissions -which could be projected up to two-thirds of total GHG emissions 6) .…”

2023

GHG emissions cause climate change and environmental degradation. The proposed research examines the role of CE in reducing GHG emissions to achieve sustainable goals and an evergreen future by recirculating materials and products. The present work identified thirteen essential CE strategies from a literature review and expert perspective to reduce GHG emissions in India's rubber industry. To provide a comprehensive explanation of the problem, the identified CE strategies were ranked by importance and categorised using the grey DEMATEL (G-DEMATEL) approach. The study offers managers and policymakers a work plan to reduce the carbon footprint.

“…In addition, the fact that fossil resources continue to be depleted also requires the search for alternative, renewable, and more sustainable resources [6][7][8][9] . Biomass from agricultural and forestry residues can be considered a potential source of production of biofuels or chemicals [10][11][12] . Most of the residues are overlooked and are just piled up in landfills.…”

Potential of Corn Cob Sustainable Valorization to Fuel-Grade Bioethanol: A Simulation Study Using Superpro Designer®

et al. 2023

The massive dependence on fossil fuels to produce ethanol has damaged the environment. This compels the quest for other alternatives using lignocellulosic materials (2 nd generation bioethanol) so as not to compete and disturb food security purposes. The promising biomass to be valorized is corn cob because of its high productivity and short harvest period. Coupled with the fact that simulation studies of its fermentation with Zymomonas mobilis to produce bioethanol are still lacking, a corn cob sustainable valorization to fuel-grade bioethanol is hence disclosed. Superpro Designer 8.5 ® was employed for simulation. Corn cob undergoes pretreatment, 2-h hydrolysis of cellulose and hemicellulose, delignification, 48-h glucose and xylose anaerobic fermentation, cells removal, vaporation, and distillation. Bioethanol is produced at 10.85%-wt from direct fermentation. Subsequently, the 1 st distillation (13 actual stages number) upgrades its concentration to 92.34%-wt. The second one (23 actual stages number) rectifies up to 99.96% and the product finally meets the criteria of fuel grade. Afterward, the calculated yield is 0.35 g/g corn cob or 44.30% based on glucose and xylose. Several by-products are also produced and to comply with the concept of sustainability, water is returned to the river, lignin and extractives are utilized for phenolic producers, wet CO2 gas is proposed for microalgae inorganic carbon sources, and stillage is returned to nature as liquid fertilizer.
