Along with industrial development especially in oil and gas sector, growth of gas flaring as a side effect of the process is also increased, this has led to problems to global climate changes due to CO2 emissions. The reduction of associated gas flaring should be done because it still has added value by applying the right technology. The paper presents a techno-economic assessment of small-scale associated gas flaring on a flow station platform to find the best recovery option. The proposed recovery options are power generation, mini LNG and mini GTL. An assessment is carried out by process simulation of the options and cash flow method. The results show that first option provides 13 million kWh/year of electricity and second option gives 20 tpd of LNG, last option produces 80 bpd of synthetic crude. Power generation requires lowest CAPEX and provides highest IRR 30.12% with NPV 4.2 million USD. Power generation option becomes the best recovery option for the small-scale associated gas flaring utilization.
