Flue gas mainly consists of N2 and CO2 and is applied in petroleum industry as a kind of displacement agents. In this paper, flue gas was introduced into the thermal recovery process of thick heavy oil reservoir. First, the PVT experiments under different conditions were carried out to research the dissolution of flue gas in crude oil. Then, a series of 3D physical simulations were performed to study the oil displacement characteristics of flue gas coupled with steam flooding in a thick reservoir with consideration of the important production parameters including oil production, oil-to-steam ratio (OSR), water cut, and oil recovery in both the steam-flooding process and the process of steam flooding coupled with flue gas. Finally, the enhanced oil recovery mechanisms of flue gas coupled with steam flooding for thick heavy oil reservoirs were summarized on the basis of the experimental results. This study provided a reference that the reasonable use of flue gas can improve recovery of thick heavy oil reservoirs while reducing greenhouse gas emissions.

“…In order to limit the consumption of fresh water, it is advantageous to use condensation systems for cooling down the flue gases coming from the combustion of lignite due to high moisture content. As shown in [1,2,3,4], the use of condensing heat exchangers enables recovery of a large flux of waste heat and reduces the emission of the pollutants. In Poland, the first condensing heat exchanger for recovery of waste heat from flue gases was built in the Białystok S.A. combined heat and power plant in 2015.…”

The paper presents studies on the impact of the process of condensation of water vapour on the process of cleaning of flue gases from acidic compounds. The measurements were carried out on a pilot-scale plant for waste heat recovery from flue gases, taking into account the process of condensation of the water vapour contained in them. The plant was connected to a lignite-fired power unit with a capacity of 360 MW located at PGE GiEK S.A., Bełchatów Power Plant Branch. The impact of the condensation of water vapour on the reduction of sulphur, chlorine and fluorine forming acidic compounds was examined. The studies show that the condensation process is conducive to removal of acidic compounds from flue gases.

“…The recovery of water vapour in flue gas is not only beneficial to the recovery of latent heat of flue gas, but also can save industrial water and reduce production cost [2]. The removal of dust in the flue gas will also significantly alleviate the increasingly severe fog and haze [3] .…”

Abstract. Industrial combustion flue gas contains fine dust, water vapor, in order to remove micro dust, and to recover water vapor at the same time. we have put forward a research on the technology of recovering water vapor and dust removal by using a cyclone separator for the first time. By studying the pressure drop, the separation efficiency and the efficiency of recovering condensed water of the flue gas, we can get the optimum technological parameters for the actual working conditions. The results show that the pressure drop increases with the increase of inlet velocity and temperature, and the rate of increase is increasing. When under the same cooling water flow rate, the dust separation efficiency increases first and then decrease with the inlet velocity increase. When the inlet velocity is near the 50 m 3 /h, the separation efficiency reaches the maximum, 96%. The amount of vapor recovery increases with the increase of cooling medium flow rate in 15 minutes. When at the same cooling medium flow rate, the recovery increases first and then decrease with the inlet velocity increase, and reaches the maximum when the inlet velocity is 60-80 m 3 /h.
