Abstract

Предложены способы предотвращения или снижения образования твердых отложений в процессе производства фосфорной кислоты мокрым способом при помощи смешивания водорастворимого функционального органического реагента на одной или нескольких стадиях процесса производства фосфорной кислоты в количестве, достаточном для предотвращения или снижения образования по меньшей мере одного вида твердых отложений.Methods are proposed for preventing or reducing the formation of solid deposits during the wet process of phosphoric acid production by mixing a water-soluble functional organic reagent at one or more stages of the phosphoric acid production process in an amount sufficient to prevent or reduce the formation of at least one type of solid deposits.
