Abstract

Natural gas condensate is a liquid phase that is present in natural gas wells. From these wells, condensates are sent to oil refineries for it to be processed into marketable petroleum products. However, before being transported to the refineries, the condensate need to be stabilized beforehand since it contains light components that could flash off in low pressure conditions. This paper aims to find the suitable conditions to stabilise a feed of “Summer Rich” condensate to maximum Reid Vapour Pressures (RVPs) of 10 psia and 12 psia for summer and winter conditions respectively. A simulation of the process has been conducted by using Aspen HYSYS (ver. 2006) software. It was found that at a column pressure of 8.5 barg and reboiler temperature of 180°C, the condensate is successfully stabilised to an RVP of 8.778 psia. The effects of four parameters, i.e. feed flow rate, feed temperature, feed pressure and reboiler temperature towards the product RVP and sulphur content are also studied. The increase in feed flow rate causes an increase in the product RVP and sulphur content. On the other hand, increasing feed temperature and reboiler temperature causes the product RVP and sulphur content to decrease. The increase in feed pressure initially causes the product RVP to increase but after reaching a certain point, the RVP starts to decrease. Besides that, the increase in feed pressure does not give a major impact on the sulphur content.
