Resumo: | The presence of inorganic substances in the composition of crude wax decreases its commercial value, requiring purification of the product. A new physical treatment on the surface of the filter media was carried out by applying the Nylon-6 nanofibers in the untreated para aramid filter. Forcespinning equipment was used in the production of nanofibers using the centrifuge technique. The performance of the nanofiber-covered filter was compared with the results obtained for other types of surface treatment of filter media of the same composition (nonwoven para aramid fiber fabric), one without physical treatment, and another treated using singeing. An experimental design was carried out to find the optimum operating temperature and pressure (170 °C and 2.5 bar, respectively). The filtrate volume, specific resistance of the filter cake, and filter medium resistance were determined keeping the filtration time, temperature, and pressure constant at 1 h, 170 ºC, and 2.5 bar, respectively. The nanofiber-covered filter showed the best performance among the studied surfaces, providing a higher wax filtrate volume and greater retention of inorganics, with values of 5.39x10-5 m3 and 99.6%, respectively. |

Um novo tratamento físico na superfície do meio filtrante foi desenvolvido aplicando as nanofibras de Nylon-6 no filtro de fibras de para aramida sem tratamento. O equipamento de Forcespinning foi empregado na produção das nanofibras utilizando a técnica centrífuga. O desempenho do meio filtrante recoberto com nanofibras foi comparado com outros tipos de tratamento em superfície de meios filtrantes (filtros de fibras de para aramida) de mesma composição, um sem tratamento físico e outro chamuscado. Um planejamento experimental foi realizado para encontrar as condições ótimas de temperatura e pressão de operação (170 °C e 2,5 bar, respectivamente). O volume de filtrado, a resistência específica da torta de filtração e a resistência do meio filtrante foram determinados mantendo o tempo de filtração, a temperatura e a pressão constantes em 1 h, 170 ºC e 2,5 bar, respectivamente. O meio filtrante recoberto com nanofibras apresentou o melhor resultado entre as superfícies estudadas, proporcionando um maior volume de filtrado de cera e uma maior retenção de inorgânicos, com valores de 5.39x10-5 m3 e 99,6%, respectivamente.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia QuímicaUFSMBrasilEngenharia QuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessCera brutaRecobrimento de meio filtranteFiltraçãoForcespinningNanofibrasTratamento físico em superfíciesCrude waxFilter media coatingFiltrationForcespinningNanofibersPhysical surface treatmentCNPQ::ENGENHARIAS::ENGENHARIA QUIMICAFiltração de ceras aplicando diferentes tratamentos físicos na superfície de meios filtrantesWax filtration applying different physical treatments on the surface of filter mediainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisTanabe, Eduardo Hiromitsuhttp://lattes.cnpq.br/9778700143605069Dotto, Guilherme Luizhttp://lattes.cnpq.br/5412544199323879Mallmann, Evandro Stoffelshttp://lattes.cnpq.br/3624152453898910Aguiar, Mônica Lopeshttp://lattes.cnpq.br/0431688649128529http://lattes.cnpq.br/1493426900873118Missau, Juliano300600000006600b1b7f60b-aaa2-4374-9587-545c489aacb9268512f6-22cf-4e60-b886-62a636c1a7a6137c19da-4a80-436c-aa83-0a189262b557d6b0623c-d90d-4a2a-bb93-ddfb0cd4b2a7279d400c-c802-47b8-a26c-78b1aab4ae49reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEQ_2017_MISSAU_JULIANO.pdfDIS_PPGEQ_2017_MISSAU_JULIANO.pdfDissertação de Mestradoapplication/pdf1777486http://repositorio.ufsm.br/bitstream/1/18517/1/DIS_PPGEQ_2017_MISSAU_JULIANO.pdf525d2ddb4eb728c2be137e3f8e824ce8MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/18517/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-816http://repositorio.ufsm.br/bitstream/1/18517/3/license.txtf8fcb28efb1c8cf0dc096bec902bf4c4MD53TEXTDIS_PPGEQ_2017_MISSAU_JULIANO.pdf.txtDIS_PPGEQ_2017_MISSAU_JULIANO.pdf.txtExtracted texttext/plain131583http://repositorio.ufsm.br/bitstream/1/18517/4/DIS_PPGEQ_2017_MISSAU_JULIANO.pdf.txt0a381f86a4b53acd85efecf98b18fad4MD54THUMBNAILDIS_PPGEQ_2017_MISSAU_JULIANO.pdf.jpgDIS_PPGEQ_2017_MISSAU_JULIANO.pdf.jpgIM Thumbnailimage/jpeg4102http://repositorio.ufsm.br/bitstream/1/18517/5/DIS_PPGEQ_2017_MISSAU_JULIANO.pdf.jpge89d2c9672ad600f9b1f14ba97da7608MD551/185172019-10-09 03:01:35.641oai:repositorio.ufsm.br:1/18517Q3JlYXRpdmUgQ29tbW9ucw==Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestouvidoria@ufsm.bropendoar:39132019-10-09T06:01:35Repositório Institucional Manancial UFSM - Universidade Federal de Santa Maria (UFSM)false |
