Abstract

The paper presents a research work on the process of emulsion separation by ﬁltration-coalescence method in the presence of solid particles. A polyester PBT coalescence medium was used in experiments of water removal from diesel fuel. Apart from parameters representing the geometry and inherent properties of coalescence ﬁlters, the additional emulsion constituents such as surfactants and solid particles also aﬀect the process. These constituent can cover ﬁbres and they can also inﬂuence emulsion properties. It has been experimentally conﬁrmed that contrary to surface active compounds, which stabilise the emulsion, the presence of speciﬁc solid particles decreased the system stability. If surface active compounds are present in the system, the inﬂuence of solid particles is diﬀerent at the same concentration level depending on their type. The destabilization of emulsion due to the presence of Arizona dust was more pronounced. Although the presence of particles mitigated the eﬀect of surfactants, their deposition in the ﬁlter media oppositely aﬀected the coalescence process depending on solid type. Oleophilic iron oxide particles improved the separation eﬃciency of water from diesel fuel, while Arizona test dust had a negative impact on the separation process performance.

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
