摘要

Addressing the increasing industrial demand for sustainable and cost-effective materials, the conversion of abundant palm frond waste into carboxymethyl cellulose (CMC) for application as a drilling fluid additive in the oil and gas industry was explored in this study. Motivated by the environmental concerns associated with conventional CMC production from wood pulp, the utilization of palm frond waste was investigated as a significant and environmentally friendly alternative. Palm fronds, sourced from Khartoum State, Sudan, underwent processing that included washing, drying, grinding, and alkali cooking to facilitate cellulose extraction, a process confirmed through Fourier-transform infrared spectroscopy (FTIR). Subsequently, CMC synthesis was achieved via alkalization of the extracted cellulose, followed by reaction with monochloroacetic acid, and purification using nitric acid, resulting in a product characterized by a degree of substitution (DS) of 0.77 and a molecular weight of 209,000 g/mol. The successful formation of CMC was confirmed through characterization using FTIR and X-ray diffraction (XRD). When evaluated as a drilling fluid additive according to API 13A standards, the synthesized CMC, despite its low-grade classification, demonstrated favourable rheological properties and superior filtration control, evidenced by a minimum 15% reduction in filtration volume compared to commercially available CMC. This quantitative enhancement in filtration performance underscores the potential of CMC derived from palm fronds as a sustainable and cost-effective substitute for traditional drilling fluid additives. The feasibility of transforming agricultural waste into a value-added product is demonstrated by this study, presenting a novel and eco-conscious approach to CMC synthesis and its application in drilling fluids. By bridging the gap between agricultural waste management and industrial material requirements, this work contributes to waste valorisation, enhanced resource efficiency, and the potential for reduced operational expenditures within the oil and gas sector, where the development of sustainable and cost-effective alternatives to conventional, potentially toxic and non-biodegradable drilling fluid additives is necessitated.
