The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

RESUMO

Pressurized entrained flow high-temperature black liquor gasification (PEHT-BLG) is a novel technique to recover the inorganic chemicals and available energy in black liquor originating from kraft pulping. One of the key parts in the PEHT-BLG process is the spray atomizer where the viscous black liquor is disintegrated into a spray of fine droplets into the hot gasifier. In this study a high-speed photography system was used in order to visualize the spray formation of black liquor and syrup/water mixtures at elevated ambient pressures based on a conventional coaxially convergent gas-assisted atomizer. The main conclusion is that the breakup and atomization of black liquor by a gas-assisted atomizer is similar to that of a syrup/water mixture with similar physical properties. The observed difference in sphericity between black liquor and syrup/water may be explained by rapid cooling of the black liquor by the cool nitrogen gas at the nozzle exit, resulting in a sudden decrease in viscosity and possible skinning of the black liquor. Furthermore, it was found that an increased ambient pressure appeared to contract the spray to a more dense cloud of droplets compared to the corresponding atmospheric case.
