Propylene content in syngas from a fixed-bed reactor
Thread Content
I have a question: does anyone among you know the proportion of propylene in syngas produced by Luchi’s fixed-bed reactor? Thank you:D
It seems that C2+ is mainly ethane; propylene cannot be ruled out, but its concentration is extremely low. What is the purpose of the landlord having this level of content?
Hello, moderator. Our company uses a fixed-bed reactor to produce SNG; the fuel used is long-flame coal. The volume percentage of ethane in the raw gas feed is 0.38%, while that of propylene is 0.165%. Based on the moderator’s experience, is this data issue serious? It mainly relates to the acrylate content
It is indeed very high; the impact is most likely on sulfur recovery, and it is probable that carbon deposition will occur as a result. I wonder how much different your approach is compared to other projects?
The project has not yet started operation; these concentration values are those of the raw materials fed into the Linde low-methane process package. However, Linde’s engineers said that these values come from Caiding Institute. Currently, according to the operating procedures of the company’s gasification plant, the propylene content in the syngas after conversion is 0.166%. It seems that all the data comes from Caiding Institute; I wonder if this data is accurate?
It’s highly unlikely to be completely accurate if it’s not trial firing data!
Well, this type of coal has indeed not been tested through firing. But I have a question: without conducting trial burns, how do the design institutes determine the contents of these compounds in the mixture during the design process? Can this data be obtained solely through elemental analysis and industrial analysis? The data provided without trial firing should not be too far off either; otherwise, it will lead to significant errors in the subsequent design
Elemental analysis, industrial analysis, and even ash fusion point are the basic data for design calculations. In the absence of trial firing, the basis for design is to estimate the coal quality for this project by referring to similar coal types; under normal circumstances the differences in results will not be significant, unless it is a coal type that has never been used before.
Well, thanks to the moderator for the reply; it’s very helpful!
