Solve Wax formation (deposition) at 3-Phase Separator during Pigging Operation

[gocnhinkysudaukhi]

Hi everyone,

i have a question and need help all of people who know about.

The question is about methods to solve (handle) wax deposition from a pipeline route to 3 phase Separator during pigging operation.

The problem mentions to wax deposition sending to Separator will fill in and block outlet lines of Oil & Water consequence Level High up and Shutdown system. is it correct?

So how to solve the wax capacity in the case. I would like to hear the Methodology & Experience in actual operation (i.e reference document source & real evidence), if any



i read some information such as

[link Point to another website Only the registered members can access]
to Removal of wax deposits within a wellbore is accomplished by:

Cutting
Drilling
Chemical dissolution
Melting—the use of hot oil, hot water, or steam
However, it's general concept and it's not focus on the case which i mention above hence i really wanna know how to do in fact.


Appreciate your help!

Hi gocnhinkysudaukhi .

i'm not yet hear about cased that wax oil flowing into 3 phase separator and make high level so it have to shut down system.

as I know , there are 3 type of oil ;
1. aromatic
2. asphalt
3. paraffin--
the paraffin oil have same characteristic with wax oil.
the paraffin oil make it hard to flowing and it have high pour point. As my experience in oil production chemical , we inject chemical pour point depressant on upstream to lowering the pour point of oil. so it can flowing in low environment temperature.
if condition oil have been stuck in pipe , usually we used paraffin solvent chemical to solve the stuck oil in pipe so oil could be flowing again.


i hope it could help you.

Hi draky,
i forward your advice to process / pipeline engineer and double check with operator in offshore. They are happy with that ^^

Thanks a lot!
