    Abstract: The invention relates to a method for operating an ammonia cooling circuit of an ammonia synthesis plant for preventing pressure variations in the cooling circuit due to varying load or outlet temperatures, wherein the method comprises: iii-1) adapting the liquid level of condensing ammonia inside the ammonia condensing unit of the cooling circuit according to the pressure of the compressed ammonia vapor stream, in which the ammonia condensing unit is a tube-shell heat exchanger; and/or iii-2) adapting the flow of cooling medium to the ammonia condensing unit according to the pressure of the compressed ammonia vapor stream of the cooling circuit; and/or iii-3) adapting the temperature of cooling medium directed to the ammonia condensing unit by recycling a portion of the cooling medium return stream. The invention relates also to an ammonia cooling circuit arranged for carrying out the method, its use for revamping an ammonia synthesis plant into a green ammonia synthesis plant, and an ammonia synthesis plant comprising the ammonia cooling circuit.

    Abstract: The present disclosure relates to a process for production of a hydrocarbon fraction from an oxygenate feedstock, comprising the steps of providing a process feed comprising an amount of an ammonia precursor, hydrogen and an amount of oxygenates at a temperature above 200° C., directing said process feed to contact a material catalytically active in hydrodeoxygenation (HDO) under hydrotreating conditions to provide a hydrodeoxygenated intermediate product, wherein said ammonia precursor provides an amount of ammonia corresponding to a partial pressure of NH3 in the presence of said material catalytically active in hydrodeoxygenation being at least 0.1 mbar, This has the associated benefit that the ammonia precursor releases ammonia by thermal reaction, such that the presence of ammonia may limit the extent of formation of high boiling product in the hydrodeoxygenation process.
