Tar plus alkali
Thread Content
Coal tar processing involves numerous adjustments, which have an impact on production, including operations, equipment, and products. It seems like less alkali is being added now; I want to add more
Add alkali again? New devices don’t add it anymore
Claimed to be world-class, textbook-level craftsmanship, with no compromises. It won’t work in actual operation; why do you want to add more?
Jiajia is healthier, but be careful with the amount.
Are you referring to adding sodium carbonate? Current manufacturing processes do not involve the use of alkali; indeed, old processes and equipment that do not use alkali suffer from severe corrosion. It depends on the requirements of your end-users for the product; mainly, it’s about the sodium ion content in asphalt and carbon black oil.
The design also features a alkali-free process, but the equipment still cannot withstand it during operation. Worse still, it blocks the gas phase pipe, affecting operational stability
Corrosion is necessary; after adding alkali, the levels of sodium ions in your asphalt, carbon black oil will definitely exceed the limits. If the gas-phase pipes get blocked, it’s necessary to blow them out more often – don’t wait until they are completely blocked before taking action
With less alkali added, equipment corrosion accelerates, especially severe corrosion occurs on trays and the tubes of tubular furnaces； A large amount of alkali leads to an increase in moisture and sodium ions; excessive sodium content results in the formation of sodium-asphalt, which is detrimental to the quality of modified asphalt, medium-temperature asphalt, and carbon black oil. The new standard for modified asphalt, YB/T5194-2015, now sets requirements regarding sodium ions.
Which pipeline do you mean by the blocked weather tube? Besides, the weathering tube has nothing to do with whether alkali is added or not, right?
What you say makes sense; a clogged gas line definitely has nothing to do with adding alkali.
