  • A PROCESS FOR GENERATION OF SNTHESIS GAS BY FLUE GAS RECYCLE
    Publication number: 20170369312
    Abstract: A novel process for synthesis gas generation comprises treating a hydrocarbon feed in a primary reformer (PR), compressing at least part of the flue gas from the primary reformer in a compressor (C1), and feeding the compressed flue gas to a secondary reformer (SR) together with the primary reformer effluent. In the process, enriched air (EA) is added either to the primary reformer, to the secondary reformer or both. The process is especially suited for co-production of ammonia and methanol or for production of either ammonia or methanol. The total CO2 emission is lowered considerably by using the process of the invention.

  • A Process for Co-Production of Ammonia and Methanol
    Publication number: 20170327383
    Abstract: In a process for co-production of ammonia and methanol, the outlet stream from the reformer is split into two parts, one of which is subjected to shift, carbon dioxide removal, methanation, compression and ammonia synthesis, while the other part is compressed and fed to a once-through methanol synthesis section. Methanol is withdrawn from the methanol synthesis section, and the remaining effluent from said section is divided into two streams comprising hydrogen, of which one is fed to the shift section, while the other is recycled to the desulfurization unit. This way a favourable co-production method is obtained because recycle hydrogen for the desulfurization is provided, and furthermore a compression step is avoided.

  • A PROCESS FOR THE ELIMINATION OF VOLATILE ORGANIC COMPOUNDS AND HAZARDOUS AIR POLLUTANTS IN AMMONIA PLANTS
    Publication number: 20170320728
    Abstract: In a process for the elimination of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) formed as by-products in the shift section (SS) of an ammonia plant, a carbon dioxide (C02) stream from a vent line, which is arranged downstream from the shift section and the C02 removal section, is recycled to the primary reformer (TR) of the ammonia plant. This way, the oxygenates contained in the carbon dioxide vent will be decomposed in the primary reformer burners, and the total emission of VOCs and HAPs will be considerably reduced.
