Parallel co-production process for the production of methanol and urea product from a hydrocarbon containing feedstock by means of autothermal reforming, intermediary methanol and ammonia formation and conversion of the ammonia to urea product and catalytic oxidation of the methanol to formaldehyde.

Process for the production of urea formaldehyde concentrate

Parallel co-production process for the production of methanol and urea product from a hydrocarbon containing feed-stock by means of primary and secondary reforming, intermediary methanol and ammonia formation and conversion of the ammonia to urea product and catalytic oxidation of methanol to formaldehyde.

A process for producing an ammonia synthesis gas, said process comprising the steps of: &#x2014;Reforming a hydrocarbon feed in a reforming step thereby obtaining a synthesis gas comprising CH, CO, CO, Hand HO, &#x2014;Shifting the synthesis gas in one in or more shift steps in series, &#x2014;Optionally wash the synthesis gas leaving the shift section with water, &#x2014;Sending the process condensate originating from cooling and washing the synthesis gas leaving the shift section to a process condensate stripper wherein the dissolved shift byproducts and dissolved gases are stripped out of the process condensate using steam resulting in a steam stream containing more than 99% of the dissolved methanol in process condensate. &#x2014;Adding all or part of said steam stream from the process condensate stripper to the synthesis gas downstream the reforming step, prior to the last shift step, wherein &#x2014;The steam/carbon ratio in the reforming step and the shift step is less than 2.6.

Ammonia process using advanced shift process

A process for producing urea with controlled excess of COand/or NH. The process includes the steps of: reforming the hydrocarbon feed gas, thereby obtaining a synthesis gas comprising CH, CO, CO, Hand HO, shifting the synthesis gas, removing COfrom the synthesis gas, removing residual HO and/or COfrom the synthesis gas, removing CH, CO, Ar and/or He, and adding stoichiometric nitrogen to produce NHto the synthesis gas, synthesizing NHto obtain a NHproduct, and adding at least part of the product COand at least part of the NHproduct to a urea synthesis step to make a urea product. The amount of excess COand/or NHis controlled by adjusting the steam/carbon in the reforming step and/or the HO addition upstream the shift step and/or adjusting the inlet temperature to at least one or more shift steps.
