Dear Experts,
I'd like to discuss about the choice of a very low capacity pump in the oil & gas sector.
The pump service is the circulation of Lean TEG: from the bottom of the Regenerator, but already cooled by 35°C below its boiling point. So, the NPSH is not a problem.
The head requested to...
Dear Experts,
I've tried to collect facts about the production of anode coke from Delayed Coking but the retrieved info are very confusing.
Could someone kindly comment on the following outcomes?
1) anode coke and calcined coke are the same material.
2) during the calcination process, the green...
I have an injection system for 2 gases.
aux line is 4" with design temperature of 100°C, operating pressure at 10 barg; main line is 24", Tdes = 300°C, Pop = 3 barg.
the mixing is realized with a special holed distributor at the end of the smaller line that enters in the main tube at 90°.
just...
Dear Refinery Experts,
What is the maximum capacity of a single-train CDU operating in a refinery?
And what is the relevant diameter of the topping tower?
I've read of a 325 kbd unit in Jamnagar but not sure it is a true figure and if it is the absolute maximum.
I'm generally interested in this...
Hi Experts.
In a previous thread (http://www.eng-tips.com/viewthread.cfm?qid=392521), Doug and Skip kindly helped me on a "copy & fill" problem.
Now I have a similar question relevant to the attached file...
Orange shaded cells in col A of the tab "ORI" contains data that I'd like to
1) move to...
Hi Experts.
Columns B and C of the attached file have "sparse data".
Would it be possible to fill - by a VBA macro - all the cells under a certain value with the same value?
For instance:
- B3, B4 -> TOYOTA (as B2)
- C9 - C15 -> MILANO (as C7)
Grateful for any help you can provide...
Dear Experts,
I'd like to obtain your valuable hints/comments on the following situation:
- there is an existing CS line currently managing hot /compressed / wet air;
- design conditions are as follows: temperature = 280 °C, pressure = 4.5 barg:
- oxygen content shall be increased up to a safe...
Dear Experts,
I'm working on a chemical process involving salty water, acetone and <3% of (heavy) vegetable oils and dissolved solids.
The process consists of a distillation under slight vacuum to recover acetone as distillate.
Vessels, heat exchangers, pumps, columns and ejectors are used at...
Dear Experts,
during a technical discussion about a refrigeration cycle with ammonia as refrigerant I've heard the following statement:
"We add 0,2%wt of water to circulating anydrous ammonia to avoid corrosion caused by hydrogen".
Is someone aware of / using this practice?
Could someone explain...
Dear Experts,
I need to define the basis of design for a vapor recovery unit that shall treat the vapors coming from an internal floating roof tank for the storage of benzene.
My assumptions are the following:
1) flowrates from the tank can be calculated following API 2000 rules.
2) yearly...
