The company has newly installed a gasoline hydrogenation unit with an annual capacity of 60 tons; take a look and see if it’s quite advanced
Thread Content
The setup is basically as follows: 1 Selective hydrogenation reactor; 2 Pre-distillation tower; 3 First-stage hydrogen desulfurization reaction, first-stage heat exchanger, first-stage cold exchanger; 4 Hydrogen sulfide stripping tower; 5 Second-stage hydrogen desulfurization reaction, second-stage heat exchanger, second-stage cold exchanger; 6 Stabilization tower
I seem to have heard at the beginning of the year that Jinzhou Petrochemical was planning an expansion with an investment of 600,000. These days, gasoline hydrogenation is generally carried out through selective hydrogenation
It’s average; currently, the best catalytic gasoline hydrogenation technology available in China is likely S_ZORB, as it results in minimal loss of octane rating
It can meet the requirements of National Standard V – what technology is used?
This post was last edited by qugd on 2015-12-17 at 10:59. S-Zorb is a non-hydrogenation process; it involves the chemical adsorption of sulfides for desulfurization using a zinc-containing catalyst. The catalyst for hydrogenation is generally nickel-containing. What makes you say that the best catalytic gasoline hydrogenation technology is S-Zorb? Compared to hydrogenated gasoline products, S-Zorb gasoline products have a higher content of olefins and gums, a lower calorific value, and poorer oxidation stability; these are all shortcomings. S-Zorb technology was developed by Sinopec in order to reduce its investment costs in oil refining; in reality, it is an outdated process used to produce products that meet standard requirements.
The hydrogenation process mentioned by the original poster isn’t really advanced; the hydrogenation process for petroleum products is generally the same everywhere, with the differences lying in the catalysts and operating conditions. In terms of benefits, the difference lies in the liquid yield; that is, the lower the loss of gasoline, the better the benefits.
The hydrogenation method mentioned by the original poster is just one of the various types of hydrogenation; it’s not particularly advanced. In fact, all such methods are aimed at reducing sulfur content and minimizing losses in octane rating!
“What makes you say that the best catalytic gasoline hydrogenation technology is S-Zorb? ”The question from the sixth floor is good; I completely agree. Indeed, S-Zorb complicates the manufacturing process. Sinopec has the funds to acquire this technology exclusively; in fact, the technologies available from other companies, including those in China, are no less effective, require less investment, and are simpler to operate. There’s no need to place undue trust in S-Zorb.
The process is too complex; from a procedural perspective, it can’t be considered advanced. Whether it is advanced or not depends on economic and technical indicators
Moreover, the 60 tons per year processing capacity mentioned by the poster is not even comparable to the medium-scale testing facilities used in research institutions; so what advancement is there in that? The feed pipe is likely around DN20 in diameter, the same as that of household water pipes; there’s no need to talk about whether it’s advanced or not. Don’t leave out that character; if it’s missing, it shows that you’re an amateur.
