A method for purging a polymer product of volatiles, the method comprising: producing a polymer product in a reactor; transferring the polymer product from the reactor to at least one purge bin; injecting a purge gas into the at least one purge bin to create a purged polymer product; discharging the purged polymer product from the at least one purge bin; determining a correlation relationship between purge efficiency, X o / X i, and (S ∗ P ∗ M) / G for one or more species of volatile purged from the polymer product, wherein: X o is the concentration in ppmw of the volatile species in the discharged purged polymer product, determined according to the example part of the description; X i is the concentration in mol% of the volatile species in a gas phase of the reactor upstream of the purge bin; S is the production rate in (kg polymer per hour of the reactor)/453.59 [corresponding to Klb polymer per hour of the reactor]; P is the absolute pressure in kPa/6.89 [corresponding to psia] within the purge bin; M is the molecular weight of the purge gas in g/mol [corresponding to lb/lb mol]; and G is the mass flow rate in (g purge gas per hour)/453.59 [corresponding to lb purge gas per hour] in the purge bin and adjusting at least one of the parameters S, P, M, or G to improve purge efficiency. producing a polymer product in a reactor; transferring the polymer product from the reactor to at least one purge bin; injecting a purge gas into the at least one purge bin to create a purged polymer product; discharging the purged polymer product from the at least one purge bin; determining a correlation relationship between purge efficiency, X o / X i, and (S ∗ P ∗ M) / G for one or more species of volatile purged from the polymer product, wherein: X o is the concentration in ppmw of the volatile species in the discharged purged polymer product, determined according to the example part of the description; X i is the concentration in mol% of the volatile species in a gas phase of the reactor upstream of the purge bin; S is the production rate in (kg polymer per hour of the reactor)/453.59 [corresponding to Klb polymer per hour of the reactor]; P is the absolute pressure in kPa/6.89 [corresponding to psia] within the purge bin; M is the molecular weight of the purge gas in g/mol [corresponding to lb/lb mol]; and G is the mass flow rate in (g purge gas per hour)/453.59 [corresponding to lb purge gas per hour] in the purge bin and adjusting at least one of the parameters S, P, M, or G to improve purge efficiency.
