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

    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
    Meltingthe 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!

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

    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!
