What is the comparison between quench heat exchangers for ethylene cracking at home and abroad?
Thread Content
Dear experts, what is the current comparison of quench heat exchangers used for ethylene cracking at home and abroad? As far as I know, the structural types currently in use in China include: Schmidt-type rapid cooling heat exchangers, linear rapid cooling heat exchangers, and thin tube sheet rapid cooling heat exchangers. Are the structural forms used domestically and abroad the same as those in China? Are the other relevant designs and operating parameters the same?
Schmidt-type rapid cooling heat exchanger? ? ?
I am unable to determine the exact source, but in my research I often encountered references to Smith-type rapid cooling heat exchangers, also known as double-tube rapid cooling heat exchangers. It might be called the Schmidt style because the inventor’s name was Schmidt, or because the company that first produced it was named Schmidt, and it was a foreign company.
