Resumo: | The filtration of gases is an important industrial operation with the primary aim of removing unwanted solid particles contained in a gas. The filtration of gases at high pressures is an operation widely used in natural gas industry with the aim of separating impurities called black powder, from rust inside pipelines along the transportation. These residues can cause wear on equipment such as, for example, rotor pump, obstruction of gauges and pressure decrease in product quality. Despite being an operation widely used, few studies exist in the area to study what the best type of filter. Therefore this study is very useful to improve the steps of transportation, measurement and purity of the final product. To simulate this process, we used the dry compressed air, injecting a phosphate rock as particulate matter. The filters were tested RAD cellulose and acrylic. The surface speed of filtration was kept constant at 0.05 m / s, throughout the filtering operation. The flow of compressed air used were 14 l / min to the total pressure 1 bar, 42 l / min at a total pressure of 3 bar and 86 l / min at a total pressure of 6 bar. Total load losses were 5, 10, 20 and 30 mbar. The results showed that, initially, the curves of head loss versus deposited mass showed the same growth trend. However, when forming a layer of cake from about 0.03 kg/m2, the filtrations higher pressures had lower pressure loss. This is because the larger pressure forming pies more porous and less resistant to air flow. At the end of the study it was also observed that the acrylic filter performed better compared to the cellulose RAD, due to its greater mass of accumulated dust and low pressure drop. |

A filtração de gases a altas pressões é uma operação muito utilizada na indústria de gás natural com o objetivo de separar as impurezas denominadas pó preto, provenientes da oxidação no interior de gasodutos ao longo do seu transporte. Estes resíduos podem causar desgaste de equipamentos como, por exemplo, rotor de bombas, obstrução de aparelhos de medição de pressão e diminuição da qualidade do produto. Apesar de ser uma operação muito utilizada, poucas pesquisas existem na área a fim de estudar qual o melhor tipo de filtro. Por isso este estudo é muito útil no sentido de melhorar as etapas de transporte, medição e pureza do produto final. Para simular este processo, foi utilizado o ar comprimido seco, injetando-se a rocha fosfática como material particulado. Os filtros testados foram de celulose RAD+ e acrílico. A velocidade superficial de filtração foi mantida constante em 0,05 m/s, durante toda a operação de filtração. As vazões do ar comprimido utilizadas foram de 14 l/min para a pressão total de 1 bar, 42 l/min para a pressão total de 3 bar e 86 l/min para a pressão total de 6 bar. As perdas de carga totais foram de 5, 10, 20 e 30 mbar. Os principais resultados mostraram que, inicialmente, as curvas de perda de carga versus massa depositada apresentaram igual tendência de crescimento. Porém, no momento que forma uma camada de torta a partir de aproximadamente 0,03 kg/m2, as filtrações de maiores pressões apresentaram menor perda de carga. Isso porque as maiores pressões formam tortas mais porosas e menos resistentes ao escoamento de ar. Ao final do estudo observou-se também que o filtro de acrílico obteve melhor desempenho comparado com o de celulose RAD+, por apresentar maior massa de pó acumulada e menor perda de carga.application/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Engenharia Química - PPGEQUFSCarBRFiltração de gasesFiltros de tecidoGás naturalPó pretoAlta pressãoGas filtrationHigh pressureCloth filterNatural gasBlack powderENGENHARIAS::ENGENHARIA QUIMICAFiltração de gases a altas pressõesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-1-1cfe199c5-37b6-4d5a-a38c-e0503b6b1995info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL4842.pdfapplication/pdf3843983https://repositorio.ufscar.br/bitstream/ufscar/4106/1/4842.pdfdba16fdf2f921799ee872793185384b3MD51TEXT4842.pdf.txt4842.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/4106/2/4842.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD52THUMBNAIL4842.pdf.jpg4842.pdf.jpgIM Thumbnailimage/jpeg6640https://repositorio.ufscar.br/bitstream/ufscar/4106/3/4842.pdf.jpgea709c8d8ea778c3d1b9bd04665af3aaMD53ufscar/41062023-09-18 18:31:33.592oai:repositorio.ufscar.br:ufscar/4106Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:33Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
