Dear all,
As a part of a program to minimize Crude Column overhead corrosion, we have a plan to improve wash water injection to the upstream of Crude Column Ovhd Condenser. Actually, such a practice have already been applied all this time, yet the wash water flow rate is considered as too low...
Good day,
I would like to know which blending correlation could be used for freezing point, smoke point, and flash point. Do they follow linear or non-linea blending correlation?. For smoke point, I think it should be linear since it represent aromatic content in jet fuel. But please correct...

Dear members,
I need information related to Tube Wall Temperature (TWT) or tube skin monitoring in Fired Heater operation. When we consider to set a high temperature alarm for the TWT in a fired heater, what temperature should (or commonly) be used as the setting? Currently, we are considering...
Dear members,
We operate a Propane Refrigerant Unit to provide chilling requirement for some chillers with various purposes. In those chillers (kettle type), shell side is continuously filled with propane in a certain level while the process fluid flows within the tube.
There are two different...

Hi, all.
Our LPG recovery plant operate a refrigeration unit which utilizes propane as the refrigerant. The propane refrigerant is used as cooling media in two HE, one of them is a Deethanizer Overhead Condenser where the deethanizer overhead vapor (consist of H2, C1, C2, C3, and a little iC4)...
