Hello,

 

Due to an emergency  blowdown of fuel gas from buffer tank to flare header, choking flow occurs at a 3" pipe line and valve.

Fuel gas is pretreated associated gas with 3700 ppmv water in it (potentially up to 18000 ppmv).

Fuel gas MW is 23 g/mol. It is used for fuel in GE 6B GTG.

Due to excessive cooling, condensation and methane-hydrate formation seems possible therefore heat tracing may be a remedy.

 

 

Before elaborating further on the definition of this problem I wonder if there is any reference (API, ASME etc) to heat tracing for such lines?

 

OR does anyone have such an experience in the field?

 

Regards,

 

ACA

 

PS: Fuel gas contains trace amounts of components of up to C10+
