(Conference object; Peer reviewed, 2015-11-25)Deep geologic injections and storage of Carbon dioxide (CO2) for enhanced oil recovery (EOR) are an upcoming combination due to the potential for increased oil production from depleted oilfields at the same time reducing ... -
Simulation of Condensation in Biogas containing Ammonia
(Peer reviewed; Journal article, 2021)Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ... -
Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS
(Journal article; Peer reviewed, 2018)Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ... -
Simulation of dew points in raw biogas using PR and SRK equations of state :
(Peer reviewed; Journal article, 2019)Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ... -
Simulation of enhanced oil recovery with CO2 injection
(Journal article; Peer reviewed, 2019)One of the goals of the Paris Agreement is to reduce the CO2 emission to the atmosphere. This paper deals with CO2-EOR, which is a good option for utilizing and storing CO2. Four cases were simulated using the commercial ... -
