We have 1 HPRT in Hydrocracker unit and 2 HPRT in VRDS unit. And they are mostly working well.
The one in HYC is ;
a. High Pressure separator liquid pressure recovery
turbine to pump charge to the unit.
And, the others in VRDS are ;
a. high pressure rich amine pressure recovey turbine
to pump lean which is used for H2S removal in
recycle gas.
b. high pressure reaction loop washing H.C pressure
recovey turbine to pump washing H.C from low pressure
