2020년 1월 1일부터 이행되는 연료유의 황 함유량 규제에 따른 대응 현황을 보면, 약 60% 이상의 선사들이 저유황유 사용을 고려하고 있다. 이처럼 높은 저유황유 선택에 따라 저유황유의 안정적인 공급에 대한 사전 검토 및 대비책을 통한 구체적인 방안이 요구되고 있으며, 저유황유의 품질 보증이 무엇보다도 중요한 사안이라 판단된다. 저유황유의 품질에 따라 예상되는 문제점을 미리 파악하고 이에 대한 적절한 대응 방안을 수립하여 선박 기관 운영에 차질이 없도록 대비하여야 한다. 그래서 선박에 공급되는 저유황유의 품질 특성 시 고려사항을 전달하고자 한다.

This study examined the background of IMO environmental regulations and countermeasures of domestic and foreign liner shipping companies and also analyzed the additional cost and profitability of container shipping companies by implementation of IMO 2020, when the fuel oil is converted to low sulfur oil. The results show that the national flag carrier would incur significant additional costs when using low sulfur oil, which would worsen its profitability in all scenarios. These analysis results suggest that for regional shipping companies need reasonable BAF setting standards, which is flexible to the price of fuel oil and also seek ways to co-exist through mutual cooperation among oil refiners, shippers and shipping companies.

최근 저유황 연료유의 공급과 청정연료의 사용 등으로 인해 1차 오염물질은 점차 줄어드는 추세에 있는 반면, 늘어나는 자동차와 급속한 산업화로 산업시설에서 배출되는 질소산화물과 탄화수소류, 휘발성 유기화합물(VOC) 등이 복잡한 광화학 반응을 통해 2차 오염물질을 생성함으로 대기오염의 문제가 심각하다.(중략)

Recently among after-treatment devices which have high possibility of utility diesel oxidation catalyst(DOC) is concerned over the world. DOC oxidizes pollutants by means of activate-reaction during by-passing in the catalyst in doing so conversion efficiency of PM, CO and HC is high and this device does not have an effect on engine performance because back pressure is not nearly increased, But as a small amount of sulfur content in fuel is oxidized it makes sulfate which is absorbed on the surface of catalyst. So in this study the experiment is carried out by means of using ordinary fuel(0.1wt%) and low sulfur fuel(0.05wt%) with DOC and the emission gas of diesel engine is measured.

In accordance with the sulfur regulations of the International Maritime Organization (IMO), very low sulfur fuel oil (VLSFO) shows various production-dependent physico-chemical properties. This study aims to use as basic data for oil spill response according to study of physico-chemical characteristics of VLSFO and mixed fuel oil of VLSFO-HSFO. The mixed fuel oil was prepared by mixing 25, 50, 75 mass% of HSFO with VLSFO containing 0.46 and 0.36 mass% of sulfur. The physico-chemical properties such as the kinematic viscosity, pour point and distribution of Saturates, Aromatics, Resins, and Asphaltenes (SARA) were studied in the laboratory. As mixed of 75 mass% of HSFO with high the kinematic viscosity and low pour point in VLSFO, the kinematic viscosity of the mixed fuel oil increased to 350.2 %, and VLSFO with pour point of 23℃ and -11℃ lowered or raised to -3℃ and -6℃ respectively. As HSFO was mixed in VLSFO with a small Asphaltenes distribution, the Saturates distribution decreased to 68.8% and Asphaltenes distribution increased to 1,417 % dramatically.

Since the enforcement of strict regulations on marine fuel oil sulfur content, demand for Low Sulfur Fuel Oil (LSFO) has been increasing. However, as LSFO properties vary greatly depending on the supply timing, region, and supplier, LSFOs can experience problems with sludge formation, blending compatibility, and stability once mixed into storage tanks. This study investigates using ultrasound cavitation effects to improve the quality of LSFOs in storage tanks. For marine gas oil (MGO), the results showed that the relative ratio of high molecular weight compounds to those of low molecular weight decreased after ultrasonic irradiation, due to cavitation-induced cracking of chemical bonds. For marine diesel oil (MDO) and blended oil, a small increase in the relative abundance of low weight molecular compounds was observed after treatment. However, no correlation between time and relative abundance was observed.

The test was conducted on an 8000cc heavy-duty turbo-charged heavy-duty diesel engine on which continuous regeneration DPF was installed in order to investigate regeneration characteristics fur DPF and engine performance under conditions of standard (430ppm) or ultra low sulfur diesel (50ppm) and the results were compared with each other. Exhaust emissions, CO, HC, NOx, PM and soot were investigated carefully and tested under D-13 and D-3 modes.
