Problems solved by technology

Steam for heat and / or energy transfer is often generated by the combustion of fuels, resulting in additional smoke generation and further loss of energy efficiency during chemical synthesis
In addition, the use of materials that would otherwise be available as reactants for combustion as fuel can also reduce the amount of desired chemical product that a chemical synthesis facility can produce from a given amount of material

Embodiment 1

[0155] Example 1: Primary and secondary reforming with electric compressor

[0156] Example 1 is a partial electrification process IV of the ammonia synthesis process described in Comparative Example 1 according to one embodiment of the present disclosure. In Process IV, partial electrification is provided by an electric compressor. The key elements of the electrified device or process IV are the Image 6 shown in ; except for the provision of energy, the process is substantially the same as in Comparative Example 1. A methane feed 205 in the amount of 59 metric tons per hour (t / hr) was fed to the process; pretreatment to remove sulfur and other deleterious components from this methane feed was not included in this model, nor in Image 6 shown in . Water 211 in an amount of 194 t / hr is evaporated and mixed with the methane feed. The resulting feed 215 is further preheated and fed to a primary reformer 220A at approximately 620°C and 690 psia where CO, CO 2 and H 2 . Ene...

Embodiment 2

[0160] Example 2: Primary and secondary reforming with electric compressor and electric furnace

[0161] Example 2 is a further portion of the electrification process V of the ammonia synthesis process described in Comparative Example 1 according to an embodiment of the present disclosure. In process V, in addition to the electric compressor of example 1, partial electrification is provided by means of an electric furnace. The key elements of the electrified equipment / process V are the Figure 7 shown in ; except for the provision of energy, the process is substantially the same as in Comparative Example 1. A methane feed 205 in the amount of 59 metric tons per hour (t / hr) was fed to the process; pretreatment to remove sulfur and other deleterious components from this methane feed was not included in this model, nor in Figure 7 shown in . Water 211 in an amount of 194 t / hr is evaporated and mixed with the methane feed. The resulting feed 215 is further preheated and fed t...

Embodiment 3

[0165] Example 3: Primary and secondary reforming with electric compressor and electric reboiler

[0166] Example 3 is a different partial electrification process VI of the ammonia synthesis process described in Comparative Example 1 according to one embodiment of the present disclosure. In process VI, in addition to the electric compressor of embodiment 1, also by (CO 2 Remove 240A) electric reboiler to provide partial electrification. The key elements of this electrified device VI are the Figure 8 shown in ; except for the provision of energy, the process is substantially the same as in Comparative Example 1. A methane feed 205 in the amount of 59 metric tons per hour (t / hr) was fed to the process; pretreatment to remove sulfur and other deleterious components from this methane feed was not included in this model, nor in Figure 8 shown in . Water 211 in an amount of 194 t / hr is evaporated and mixed with the methane feed. The resulting feed 215 is further preheated and...

Abstract

An ammonia synthesis plant comprising: a feed pretreating section operable to pretreat a feed stream; a syngas generation section operable to reform the feed stream to produce a reformer product stream; a shift conversion section operable to subject the reformer product stream to the water gas shift reaction, to produce a shifted gas stream comprising more hydrogen than the reformer gas stream; a purification section operable to remove at least one component from the shifted gas stream, and provide an ammonia synthesis feed stream; and / or an ammonia synthesis section operable to produce ammonia from the ammonia synthesis feed stream, wherein the ammonia synthesis plant is configured such that, relative to a conventional ammonia synthesis plant, more of the energy required by the ammonia synthesis plant or one or more sections thereof is provided by a non-carbon based energy source, a renewable energy source, and / or electricity.

Description

technical field [0001] The present disclosure relates to the use of renewable energy in ammonia synthesis; more particularly, the disclosure relates to the electrification of ammonia synthesis plants; / fossil fuels) to reduce environmental emissions such as carbon dioxide. Background technique [0002] Chemical synthesis equipment is used to provide a variety of chemicals. Typically, specialized fuels are burned or "burned" to provide reaction heat for chemical synthesis, energy to heat one or more process streams, energy to vaporize liquids (e.g., using boiling water as a diluent), work (e.g., to drive a compressor or pump) ) or energy for other process operations of the entire chemical synthesis facility. Such flaring or burning of fuels leads to the generation of fumes which may be harmful to the environment, and also leads to a loss of energy efficiency of the process. Likewise, steam has traditionally been utilized as a plant-wide heat and / or energy transfer fluid wi...
