Answer: Advantages: (1) High yield of hydrogenated refined liquid, which can reach 98–99% ； (2) No acid or alkali residues are produced ； (3) It consumes less electricity than electrochemical refining (unless otherwise specified, all questions and answers are based on hydrogenation units). ) For management purposes, if you need to view content from a few days ago, please go through the summary post below. 2017 Q&A Summary Thread (updates have begun) https://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) https://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) https://bbs.hcbbs.com/thread-1597792-1-1.html (Source: Haichuan Chemical Industry Forum)
No waste residue; wide and deep impurity removal range, with good product stability
1. The yield of the hydrogenated refined liquid can reach 98–99%； 2. No acid or alkali residues are produced ； 3. Less power consumption compared to electrochemical refining
(1) The yield of the hydrogenated refined liquid is high, reaching 98–99% ； (2) No acid or alkali residues are produced ； (3) Less power consumption than electrochemical refining
It causes minimal environmental pollution and does not generate difficult-to-treat substances such as alkaline slag
Hydrorefining results in low processing losses, high product yields, and minimal environmental pollution.
Advantages: (1) High yield of hydrogenated refined liquid, which can reach 98–99%. (3) Less power consumption compared to electrochemical refining. The reason is that due to the competition between acids and bases, as well as in the electrochemical process, polymer compounds containing nitrogen, oxygen, and sulfur, such as thiophenes, pyridines, and oxyacids, are removed in their entire compound form.
Advantages: 1? High yield of hydrogenation refined product, up to 98–99%. 2? No acidic or alkaline residues are generated. 3? Less power consumption compared to electrochemical refining. Reason: Due to the competition between acids and bases, as well as in electrochemical processes, polymer compounds containing nitrogen, oxygen, and sulfur, such as thiophenes, pyridines, and oxyacids, are removed in their entirety as compounds. High oil loss? Low product yield. Hydrorefining converts the aforementioned compounds into low-molecular-weight hydrocarbons as well as water, hydrogen sulfide, and ammonia; the low-molecular-weight hydrocarbons remain in the oil as products, while ammonia, hydrogen sulfide, and water can be separated and removed from the product, thus resulting in a high yield.
Advantages: (1) High yield of hydrogenated refined liquid; (3) Lower power consumption compared to electrochemical refining, as hydrogenation converts the aforementioned compounds into low-molecular-weight hydrocarbons as well as water, hydrogen sulfide, and ammonia.
High liquid recovery, no acid or alkali discharge, low power consumption
