Abstract
Systems and methods for the production of acrylic acid include vaporizing a propylene feed and separately compressing an air stream. The compressed air may be mixed with steam or recycle gas, or both. The vaporized propylene and the compressed air mixture are combined and mixed at a mixer to produce a reaction feed. The reaction feed is mixed at a lower temperature than the reaction temperature of the reaction feed to improve safety. The reaction feed is heated to the reaction temperature by a heat exchanger downstream of the mixer. The heating medium in the heat exchanger may be steam to control the heating process and further improve safety.

A system, comprising:
- a first heat exchanger configured to heat a propylene stream and output a vaporized propylene stream;
- a compressor configured to compress an air stream and output a compressed air stream;
- a mixer in fluid communication with the first heat exchanger and the compressor;
- and
- a second heat exchanger in fluid communication with the mixer downstream of the mixer relative to a direction of flow through the mixer,
- wherein the mixer is configured to mix the vaporized propylene stream and the compressed air stream and output a reaction feed, and
- wherein the second heat exchanger is configured to heat the reaction feed to a reaction temperature.
A system, comprising:
- a mixer;
- and
- a heat exchanger in direct fluid communication with the mixer downstream of the mixer relative to a direction of flow through the mixer,
- wherein the mixer is configured to mix a vaporized propylene stream and an air stream and output a reaction feed at a temperature lower than a reaction temperature of the reaction feed, and
- wherein the second heat exchanger is configured to heat the reaction feed to the reaction temperature.
A method, comprising:
- heating a propylene stream at a first heat exchanger, including outputting a vaporized propylene stream from the first heat exchanger;
- compressing an air stream at a compressor, including outputting a compressed air stream;
- mixing the vaporized propylene stream and the compressed air stream at a mixer and outputting a reaction feed from the mixer;
- and
- heating the reaction feed to a reaction temperature at a second heat exchanger downstream of the mixer relative to a direction of flow through the mixer.
