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 all, I am seeking information about gasoline stability related to the existence of gum and olefin. My refinery has to deal with a condition where it has to blend a small amount of untreated delayed coker naphtha to the gasoline product. Even though we can minimize the proportion, still...

Dear Aaronb82, You could see in the appendix of this following reference from Pall for the method: http://www.pall.com/pdf/GDS120.pdf Once I was informed by an MDEA manufacturer that they use these following numbers to interpret the result of such analysis and determine the severity of...

Dear Jason and Dosto, Thanks for this great discussion. I have also found a good reference in this link : ipec.utulsa.edu/Conf2006/Papers/Braden_92.pdf Have a nice day, guys.

thread483-123687 My refinery haven't had experience to process crude oil with high mercury content before, but I'm sure that it will be a possibility in the near future that must be anticipated. What I would like to know is about the mercury in the waste water. Which waste water stream that...

dh328, Thanks for your helpful response. You said that the alarm setting could depend on the function of the heater. Could you please share further information about that statement? Have a good day.

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...

CJKruger and Domz, Big thanks for your helpful response. Cheers

BenThayer and dCasto, Thanks for the enlightenment! @ dcasto: It's correct. The propane vapor from the MDEA cooler then goes to an Economizer (a vertical vessel) where the vapor from its top then routed to the Refrigerant Compressor Interstage

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)...
