On the steam demand in the petrochemical industry
Thread Content
Hello everyone, I have a question: what are the steam parameters required in the petrochemical industry, and what are those requirements for PTA projects? Why do some petrochemical industries require 3.5 MPa to drive the air compressor, while others can use 1.1 MPa? What is the difference? The role of steam in the petrochemical industry. Thank you all. Please explain it; the more detailed, the better.
This has little to do with power requirements; it is mainly determined by the quality of steam generated by the device. If high-pressure steam is produced, it should be used for driving the system, while if low-pressure steam is produced, that shall be used instead. If high-pressure steam is utilized for driving, the resulting low-pressure steam can further power systems with lower power demands. It can also be sent to low-pressure or ultra-low-pressure pipelines for use as a heating medium for heat tracing purposes. In general, steam-driven systems represent an energy-saving measure that replaces temperature and pressure reduction equipment in order to make better use of energy.
