Wax Crystallization

Energy-efficient recovery of oil droplets from ice-cold water, such as oil sands tailings, marine, and arctic oil spills, is challenging. In particular, due to paraffin wax crystallization at low temperatures, the crude oil exhibits high viscosity, making it difficult to collect using simple solutions like sponges. Here, we report a wax-wetting sponge designed by conforming to the thermoresponsive microstructure of crude oil droplets. To address paraffin wax crystallization, we designed the sponge by coating a polyester polyurethane substrate with nanosilicon functionalized with paraffin-like octadecyl ligands. The wax-wetting sponge can adsorb oil droplets from wastewater between 5° and 40°C with 90 to 99% removal efficacy for 10 cycles. Also, upon rinsing with heptol, the adsorbed oil is released within seconds. The proposed approach of sponges designed to conform with the temperature-dependent microstructure of the crude oils could enable cold water technologies and improve circular economy metrics in the oil industry.

The Impact

The release of liquid hydrocarbons into the water is one of the environmental issues that have attracted more attention after deepwater horizon oil spill in Gulf of Mexico. The understanding of the interaction between liquid droplets impacting on an immiscible fluid is important for cleaning up oil spills as well as the demulsification process. Here we study the impact of low-viscosity liquid drops on high-viscosity liquid pools, e.g. water and ethanol droplets on a silicone oil 10cSt bath. We use an ultrafast camera and image processing to provide a detailed description of the impact phenomenon. Our observations suggest that viscosity and density ratio of the two media play a major role in the post-impact behavior. When the droplet density is larger than that of the pool, additional cavity is generated inside the pool. However, if the density of the droplet is lower than the pool, droplet momentary penetration may be facilitated by high impact velocities. In crown splash regime, the pool properties as well as drop properties play an important role. In addition, the appearance of the central jet is highly affected by the properties of the impacting droplet. In general, the size of generated daughter droplets as well as the thickness of the jet is reduced compared to the impact of droplets with the pool of an identical fluid.

ABSTRACT In August and October 1980, two large oil spills occurred in the Arabian Gulf. The first, from an unidentified source, involved about 20,000 barrels of crude oil and impacted the entire north and west coasts of the island nation of Bahrain. The second occurred when the Ron Tapmeyer platform in the Hasbah offshore oil field blew out, releasing an estimated 50,000 barrels of thick crude into the Gulf. The spill subsequently covered large sections of the coastline of Qatar. The fate of the oil from these spills is examined with respect to the unique conditions found in the region. A computer model is used for trajectory analysis of the spills and hypothesizing the possible origin of the first spill. Methods of cleanup and problems with the weathered oil are mentioned. The environmental damage caused by the Bahrain spill is assessed.

Abstract. Novianty R, Saryono, Awaluddin A, Pratiwi NW, Hidayah A, Juliantari E. 2021. The diversity of fungi consortium isolated from polluted soil for degrading petroleum hydrocarbon. Biodiversitas 22: 5077-5084. One of the major problems in the petroleum industry nowadays is crude oil spills. Riau Province, Sumatra is one of the largest oil producers in Indonesia. Accidental releases of petroleum products are of particular concern to the environment. The process of drilling and refining petroleum generates a large amount of oil sludge. One of the effective technologies used in the waste degradation process is bioremediation using certain microorganisms. The prime objective of the current research was to evaluate the efficiency of fungi consortiums in crude oil degradation in Bumi Siak Pusako-Pertamina Hulu, Indonesia. There are three potential fungi isolates as petroleum hydrocarbon degradation agents with four consortium variations. The parameter values of Optical Density (OD), pH, and diluted CO2 were measured on 0, 4, 8, and 16 days. To evaluate the fungal biodegradation activity using Gas Chromatography-Mass Spectrometry (GC-MS). The result showed that consortium II (KF II) has the highest potential to degrade petroleum hydrocarbon (50.61%). The visual GC-MS examination confirmed a decrease in the peak area for eight hydrocarbon compounds, indicating the efficiency of the fungi in the oil decomposition and dismantling of hydrocarbons. Our findings may provide new information on native fungal resources from chronically contaminated terrestrial environments, and will be useful for petroleum-contaminated bioremediation and other industrial applications.
