1.jpgSailing graduated with a bachelor's degree in nuclear power engineering and a master's degree in thermal engineering. He has been engaged in chemical process and power engineering design for more than 30 years. He is familiar with coal chemical industry, petrochemical industry, fine chemical industry and power plant process. He is good at process system flow simulation, system energy optimization and pinch design, process calculation and structural design of various heat exchange equipment.

Experts have a question. The desulfurization system of the hydrogenation unit was temporarily shut down at 11 o'clock, and the outlet flow rate of the reciprocating circulating hydrogen compressor increased from 7.8w to 8.7w. So will the hydrogen sulfide content in the circulating hydrogen affect the measurement of the outlet orifice flow meter? No. So what causes the traffic to increase so much?
Hello, I would like to ask a question about HTRI. The superheated water vapor condenses on the shell side and the water circulates on the tube side. It is a high and low pressure heater commonly used in power plants. When designing HTRI, should the material on the shell side choose water from the database, or should I enter the corresponding physical property parameters myself (the phase change 1-0 has been entered in the initial interface). I found that similar heaters usually have cross-flow, rather than simple downstream or counter-flow. In this case, how should the hand-calculated △t be calculated?
https://bbs.hcbbs.com/thread-2101430-1-1.html I would like to ask a question, teacher, put the liquid nitrogen in a closed container (fully filled) at normal temperature and pressure and then heat it. Which specific heat is Q=cm△T? Is the heat transfer along the isochoric line on the pressure-enthalpy diagram?

Is there any heat exchanger manufacturer with contact information? My contact information Hebei Huafeng QQ79781876
Find various types of serpentine tube heat exchangers (economizers) that belong to cross flow. How to look up the logarithmic mean temperature difference correction coefficient of this heat exchanger in a table. for example: The smoke temperature is 130℃, dropped to 60℃, the water inlet temperature is 45℃, raised to 90℃, how to correct this logarithmic average temperature difference?:):) Please tell me
