Abstract

Coalescence filter elements composed of fibrous materials can effectively remove oil mist from gas stream. Recent studies have demonstrated that wettability is a critical factor influencing the coalescence filtration performance of filter media. Superoleophobic materials have attracted attention from researchers due to their remarkable oil-repellent properties. In this study, glass fiber materials were used as the substrate, and a home-made modified solution was applied using a combined two-step process of immersion and spraying to produce superoleophobic filter media with a contact angle exceeding 150° for DEHS droplets, other structural parameters of the filter media were not altered. Furthermore, the modified superoleophobic filter media prepared by the two-step process were compared to filter media modified by using different methods. The results show that the filter media prepared by the two-step process show excellent and stable superoleophobicity. After incorporating a strip-patterned treatment, the filtration efficiency for oil mist particles larger than 40 nm was improved from 89.13 % to 94.77 %, while the steady-state pressure drop was reduced by 46.59 % compared to the oleophilic substrate.

期刊介绍: Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
