The present invention relates to a process and an apparatus for utilizing fossil energy with low carbon emissions, which belongs to a technical field of clean energy and climate mitigation. The present invention is applicable for utilizing fossil, biomass and other carbon-containing fuels in coastal and marine areas to produce clean energy with low carbon emissions to atmosphere and low cost. The process comprises the main steps of carrying out the oxygen enriched combustion and using seawater to scrub the flue gas once to realize carbon capture, and the scrubbing water is recovered to a water quality in accordance with legal requirements and then is discharged into the ocean to realize carbon storage of ocean natural alkalinity, so that the resources of carbon sink and carbon pool in natural ocean are used to reduce greenhouse gases in the atmosphere in a safe and environment-friendly form.

A process is described, as well as a plant, for treating a raw vent gas (4,4′) containing bitumen vapours and released by a piece of equipment (1) of a polymer-bitumen membranes production line, in which operations are carried out involving a filler powder (3), such as an operation of mixing the filler powder (3) with the bitumen (2), during which the raw vent gas (4,4′) is changed from a substantially powder-free raw vent gas (4), into a raw vent gas (4′) containing the filler powder (3). The process includes steps of first conveying the raw vent gas (4,4) into a gas-washing device (20) along with a solution (9) of a surfactant; contacting the raw vent gas (4,4) with the solution (9) and removing the powder from the powder-containing gas (4′), releasing a purified vent gas (5) that is substantially free from the filler powder; conveying the purified vent gas (5) into a boiler (40) and burning the bitumen vapours. In a preferred exemplary embodiment, it is conveyed in the gas-washing device only the powder-containing gas (4′) produced during the operations of the piece of equipment (1) that involve the filler powder (3), while in the remainder steps the substantially powder-free raw vent gas (4) is directly conveyed into the boiler (40) by a direct vent line (50) that can be automatically selected. In a preferred exemplary embodiment, the gas-washing device comprises a tank (25) configured to form inside a predetermined head of the washing solution (9) and having an inlet port for the raw vent gas arranged below the liquid head. The process prevents the powder from quickly reaching the boiler (40) making the burner and the heat-exchange surfaces ineffective.
