My First Webinar: Sustained Heat Transfer Fluid Performance

Last time, I had an opportunity to participate in a free webinar held by Chemical Engineering Online. Topic of the webinar was how to sustained heat transfer performance.

I was eager to participate in this webinar because of three reasons. First, the webinar was practical. Second, speaker of webinar was from Therminol, which is one of heat transfer fluid. Third, I indirectly was heat transfer fluid user for two projects. So that, I need to understand about this topic if there is application opportunity in the future.

The first project I used heat transfer fluid was in Rosin Plant and Its Derivatives in Pemalang. The heat transfer fluid was used as heating medium in reactors. The second project was in Senoro Gas Development Project in Central Sulawesi. There are acid gas removal, dehydration unit, and stabilizer that need heat transfer fluid as heating medium. Read More

Sizing of Expansion Tank for Hot Oil System

I want to share my experience about sizing of expansion tank especially for thermal oil heater. It is quite simple actually. I will give you an example.

Function of Expansion Tank

The functions of expansion tank are:

  • Serves as the safe outlet for the increase in thermal fluid volume due to thermal expansion
  • Provides a mechanism for venting water, incondensibles, degradation by products and entrained air during start-up and operation

Sizing Expansion Tank

Hot oil system with expansion tank

When selecting an expansion tank, the system volume (including the initial fill) of the expansion tank, the operating temperature and the fluid’s coefficient of thermal expansion should all be considered. Because thermal oils expand at different rates, the expansion tank capacity always should be verified against the oil properties prior to filling the system. Read More

Thermal Oil Heater

My current job is to select vendor who will supply thermal oil heater. It is pretty hard work for me because I did not involve in thermal oil heater design since the beginning. Unlike water treatment plant which I deeply learnt since the beginning, I even don’t have any idea about thermal oil heater, so I need to learn harder. Since I am not a fast learner, I write this post as the methode (which I like the most) for me to understand what thermal oil heater is and how to select appropriate thermal oil heater. Read More
