The invention discloses a method for preparing sulphuric acid by economically recovering sulfur dioxide in low-concentration or noncontinuous flue gas, which comprises that: the flue gas containing the sulfur dioxide is subjected to purification, dust and impurity removal, temperature reduction, and acid mist removal, and then divided into two paths; one path of the flue gas is sent to a desulfurization working section, high-purity SO2 gas generated after absorption and desorption of the flue gas is evenly mixed into the other path of flue gas which is not subjected to desulfurization, the SO2 concentration of the mixed flue gas is improved to be more than 5 percent, and the mixed flue gas enters a single-conversion single-absorption acid preparation working section; and tail gas after acid preparation enters the desulfurization working section again for desulfurization, and is discharged after the SO2 content is far lower than the discharge standard. The process changes smelter off-gas which cannot meet the requirement of preparing acid by a contact method originally into the flue gas which can prepare the acid normally, and does not need desulfurizing all the flue gas, so the method greatly reduces energy consumption, running cost and investment, and the discharge amount of SO2 is far lower than that of a conventional flow so as to solve a difficult environmental protection problem for partial non-ferrous metallurgical plants and accord with the policy of national energy saving, energy consumption and pollution reduction.

The invention relates to an oil-field largest swept volume chemical-flooding oil production method, which is applied to the technical field of oil production in oil fields. The method is applicable to all reservoirs which can be exploited by water flooding but are not exploited by water flooding. When oil is exploited, the self energy of the strata of a reservoir is first utilized to carry out flowing production or swabbing production; when an oil field adopting flowing production or swabbing production reaches the economic benefit limit of production, flowing production or swabbing production is ended, subsequent water-flooding production is not carried out any more, but chemical flooding injecting surfactant as main agent is directly adopted to intensify oil production. The method has the following advantages that: at the moment, the swept volume of the displacement of the chemical displacing fluid is the largest, which is best favorable for the exertion of the oil-washing effect ofthe surfactant, and thereby the yield of oil production can be increased to the max.
