Methods of Enhanced Oil Recovery (EOR) from an oil reservoir by COflooding are disclosed. One method comprises producing a well stream from the reservoir; separating the well stream into a liquid phase and a gas phase with a first gas/liquid separator, wherein the gas phase comprises both COgas and hydrocarbon gas; cooling the gas phase with a first cooler; compressing the gas phase using a first compressor into a compressed stream; mixing the compressed stream with an external source of COto form an injection stream; and injecting the injection stream into the reservoir. Systems for EOR from an oil reservoir by COflooding are also disclosed.

The present invention relates to a system for desorption of acid gas () from an acid gas rich absorption liquid having a steam part () and a process part (). The steam part () and the process part () are separated to prevent intermixing of fluids in the steam part with fluids in the process part. The system () comprises a desorption cylinder () which is adapted to rotate about a longitudinal axis of rotation A of the desorption cylinder (), and a stationary support stand () for supporting the desorption cylinder (), and means for rotating () the desorption cylinder. The steam part () and the process part () are integrated in the desorption cylinder () and steam is supplied to the steam part () and acid gas rich absorption liquid () is supplied to the process part (). The process part () comprises a desorption chamber () provided with a stripper unit () having an integrated reboiler () and the process part () is provided with means for discharging an acid gas lean absorption fluid () and having means for removing acid gas rich vapor (), and the steam part () is provided with means for discharging condensate (). The present invention also relates to a method for desorption of acid gas from an acid gas rich absorption liquid.

The invention relates to a continuous process for removal of acid gas, such as carbon dioxide (CO2) from a fluid stream, such as natural gas comprising mainly hydrocarbons, by means of a absorbent medium in a rotating absorption zone. Subsequently, the acid gas is desorbed in a rotating desorption zone from the absorbent medium to allow the absorbent medium to be recirculated and the acid gas is removed for storage or drying and processing. This process can be carried out continuously, as the absorption medium is re-used.

A gas-liquid separator includes a housing which encloses a separation chamber, an inlet port for feeding the multi-phase flow into the separation chamber, a liquid outlet port for discharging the liquid dominated flow from the separation chamber and a gas outlet port provided at a position above both the inlet port and the liquid outlet port for discharging the gas dominated flow from the separation chamber. Both the inlet port and the liquid outlet port are positioned adjacent to an elongated lower bottom wall of the housing and define a flow direction into the and out of the separation chamber approximately aligned along the bottom wall. The separation chamber extends above the bottom wall in between the inlet port and the liquid outlet port. The liquid outlet port is provided with a gas seal to prevent entrainment of free gas from the separation chamber into the liquid outlet port.
