Abstract
Low-viscosity marine fuel oil that is obtained from the products of residual raw materials and middle distillate fractions of oil is intended for use in ship engines instead of a diesel fuel. A real-world application of this new composition is of great importance A proposed new composition of low-viscosity marine fuel oil is created by compounding a mixture of oil distillates in accordance with the following parameters. The oil distillate mixture should contain a vacuum distillate fraction 420-490°C, a vacuum distillate fraction 350-420°C and a straight-run diesel fraction 180-350°C taken in certain ratios. This study presents the new fuel composition and its technical advantages over previous analogues. The benefits include improvements in the coking properties and storage stability due to the stability in the pour point indicator.
Highlights
Development of technologies focused on the advancement of oil refinery and more rational use of oil products is timely and of high interest
The results presented in this study substantiate the technical advantages of the new fuel composition compared to previously known analogues
As a result of this research which was undertaken with an objective to eliminate disadvantages of previously known analogues associated with coking and pour point, a new method for obtaining LMF has been developed
Summary
Development of technologies focused on the advancement of oil refinery and more rational use of oil products is timely and of high interest. Low-viscosity marine fuel oil (hereinafter “LMF”), obtained from the products of residual raw materials and middle distillate oil fractions, is intended for use in marine power plants in lieu of a diesel fuel. The new composition is of great practical importance [1,2,3,4,5]. The article presents the development and the invention of a new method of producing LMF, and a number of its technical advantages over previously known analogues related to the coking index and storage stability [4] According to the technical specifications [1, p. 3; 4, p. 2] set forth in the Russian regulatory document, technical characteristics of LMF must satisfy the conditions outlined in Table 1 (in Tables 1-8: the indicator of water content “traces” refers to the absence of water within the limits of measurement accuracy; “GOST” is an interstate regional standard of the Commonwealth of Independent States of the Eurasian Economic Union).
