... that the 1D simulations reproduce the maldistribution of the liquid content of two parallel flowlines. Based on the simulations, an explanation is proposed for the occurrence of the unequal split. INTRODUCTION The sizing of a gas-condensate flowline is mainly driven by two constraints. The first constraint...
