Abstract

resumo "reduzindo a incrustação de aliminosilicato no processo bayer" a presente invenção refere-se a um método para inibir o acúmulo de incrustação dsp no circuito de licor de equipamento de processo bayer. o método inclui adicionar uma ou mais pequenas moléculas baseadas em silano particulares ao circuito de fluido de licor. esses inibidores de incrustação reduzem a formação de incrustação dsp e aumentam assim a vazão de fluido, aumentam a quantidade de tempo que o equipamento de processo bayer pode ser operacional e reduzem a necessidade de lavagens ácidas dispendiosas e perigosas do equipamento de processo bayer. como um resultado, a invenção fornece uma redução significativa no custo total de operar um processo bayer.Abstract "Reducing Aliminosilicate Fouling in the Bayer Process" The present invention relates to a method for inhibiting the accumulation of dsp fouling in the liquor circuit of bayer process equipment. The method includes adding one or more particular small silane-based molecules to the liquor fluid circuit. These scale inhibitors reduce dsp scale formation and thus increase fluid flow, increase the amount of time that bayer process equipment can be operational, and reduce the need for expensive and hazardous acid washes of bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a bayer process.
