Maintaining high - quality control is essential in the dewaxing sector. The dewaxed product must meet strict specifications in terms of its wax content, viscosity, and other properties. Variability in feedstocks can pose a challenge to quality control. Different feedstocks may have different wax compositions and properties, which can affect the dewaxing process and the quality of the final product.

Process stability is also crucial for quality control. Any fluctuations in the dewaxing process, such as changes in temperature, pressure, or catalyst activity, can lead to variations in product quality. Dewaxing companies need to implement strict process monitoring and control systems to ensure consistent product quality.
