Abstract

Настоящее изобретение относится к способу получения и обработки смеси синтез-газа для производства аммиака, в котором содержащую углеводороды и водяной пар подаваемую газовую смесь превращают с помощью кислорода в установке (49) автотермического риформинга в сырую смесь синтез-газа, которую, после последующей обработки, подают по меньшей мере на один синтез (15, 45) аммиака, причём в установку (49) автотермического риформинга подают только одну часть (48) потока подаваемой газовой смеси, вторую часть (32) потока подаваемой газовой смеси направляют в первичную установку (33) риформинга и затем во вторичную установку (20) риформинга, причем полученная в этих первичной и вторичной установках риформинга газовая смесь, при необходимости после последующей обработки, также направляется на синтез (15, 45) аммиака, при этом смесь (44) синтез-газа доводят до повышенного давления, соответствующего давлению синтеза аммиака, при этом только после повышения давления смеси синтез-газа дополнительный азот вводят по меньшей мере из одного трубопровода (14, 57) до того, как смесь синтез-газа поступит на одно- или многоступенчатый синтез аммиака. Преимущество этого способа состоит в том, что достигается существенное снижение нагрузки на все технологические узлы, расположенные между вторичной установкой риформинга и основным синтезом, включая компрессор технологического воздуха и компрессор синтез-газа. По сравнению с вариантом с наличием только одной установки автотермического риформинга при комбинации согласно изобретению с первичной установкой риформинга, наряду с прочими преимуществами, достигается, например, также преимущество, заключающееся в том, что может утилизироваться тепло в канале дымового газа первичной установки риформинга.The present invention relates to a method for producing and processing a synthesis gas mixture for the production of ammonia, in which the supplied gas mixture containing hydrocarbons and water vapor is converted using oxygen in an autothermal reforming unit (49) to a crude synthesis gas mixture, which, after further processing, at least one ammonia synthesis (15, 45) is supplied, and only one part (48) of the feed gas mixture flow is supplied to the autothermal reforming unit (49), the second part (32) of the feed gas mixture flow is sent to the primary plant (33) reforming and then to the secondary reforming unit (20), whereby the gas mixture obtained in these primary and secondary reforming units, if necessary after subsequent processing, is also sent to the synthesis of (15, 45) ammonia, while the mixture (44) of synthesis gas is adjusted to an elevated pressure corresponding to the pressure of the synthesis of ammonia, while only after increasing the pressure of the mixture of synthesis gas additional nitrogen is introduced from at least one pipeline (14, 57) before the synthesis gas mixture enters the single or multi-stage ammonia synthesis. The advantage of this method is that a significant reduction in the load on all process units located between the secondary reforming unit and the main synthesis is achieved, including a process air compressor and a synthesis gas compressor. Compared to the embodiment with only one autothermal reforming unit, when combined with the primary reforming unit according to the invention, among other advantages, for example, an advantage is also achieved that heat can be utilized in the flue gas channel of the primary reforming unit.
