Selection of optimal modes of obtaining broad fractions of light hydrocarbons from oil-associated gas at oil production sites

goals of the proper extraction of hydrocarbons from oil-associated
gas (OAG). Despite the potential of a proper OAG utilization, oil
companies often struggle with an increase in the overall gas cost
and possible unprofitability of its treatment though conventional
methods (Igitkhanyan et al., 2014). These cost-related issues have
been mentioned before by authors like Braginskii and Chernavskiito
(2011) and Arutyunov et al. (2017). This paper introduces a novel
method for OAG separation and the subsequent obtention of the
Broad Fraction of Light Hydrocarbons (BFLH) that relies on
compression followed by the cooling. The proposal is implemented
on a mobile laboratory unit developed to define power expenditures
and optimize the modes of obtaining broad fractions of
hydrocarbons from OAG at oil fields with low gas factor and
caloricity due to high nitrogen content. The experiments of the
paper contributed validating the proposed method and the mobile
unit, and this, among others, by determining optimal modes for the
obtention of the BFLH from AOG with different initial
compositions of hydrocarbons components and harmful admixtures,
and also by determining concrete values for the dependence of the
OAG compression pressure on temperature.
