TL;DR: In this paper, the byproduct gas is heated to a temperature required for carbonization and reduction of briguette, it as a high-temperature gas is refed from the lower part of the shaft furnace 4 to the furnace, so that ferro coke having improved reduction efficiency can be produced continuously and energy is reduced.
Abstract: PURPOSE:To improve reduction efficiency extremely, and to obtain molded ferro coke from a mixture of coal and iron ore continuously, by circulating a by- product gas as a reducing agent through a furnace repeatedly. CONSTITUTION:The molding device 2 of a mixed raw material of coal and iron ore and the storage tank 3 of the molded raw material are set below the blending tank 1 of the raw material of coal and iron ore, having an outlet and inlet of a by-product gas. The by-product gas channel 6 which is opened to the top of the shaft furnace 4 having a communicating hole to the storage tank 3 of the molded raw material at the upper part and an outlet of red-hot coke at the bottom, partially communicated through the by-product gas heater 5 to the lower part of the shaft furnace 4, and partially communicated to the blending tank 1 of the raw material is set. The by-product gas is heated to a temperature required for carbonization and reduction of briguette, it as a high-temperature gas is refed from the lower part of the shaft furnace 4 to the furnace, so that ferro coke having improved reduction efficiency can be produced continuously and energy is reduced.

TL;DR: In this article, the utility model relates to a high-efficient desulfurization, denitration, dust removal and water conservation integration process system, which includes reaction storehouse and gas collection storehouse.
Abstract: The utility model relates to a high -efficient desulfurization, denitration, dust removal and water conservation integration process systems. This system including reacting the storehouse, sets up the aeration pipe in the reaction storehouse, reacts the storehouse and sprays the storehouse intercommunication, sprays above -mentioned gas collection storehouse, the defroster of setting gradually in storehouse, spray the storehouse through gas gas heater with advance the mouth and be connected, spray the storehouse and be connected through spraying back the liquid pipe and spraying the circulation oxidation pond, spray the circulation oxidation pond and link to each other through spraying the circulating pump and spraying the storehouse, reaction storehouse and gas collection storehouse are passed through uptake shaft and are communicate, the gas collection storehouse is connected through clear solution back flow and clear solution case. The utility model discloses having reduced desulfurizing tower entry gas temperature, having made the desulfurizing tower evaporation water yield reduce, exhaust gas temperature is low, and wet flue gas comdenstion water reduces, has practiced thrift the water consumption, to spray desulfurization process with tympanic bulla desulfurization process ingenious combination be in the same place. Desulfurization efficiency has reached more than 99%, and the flue gas sulfur content is less than 15 mgNm3.

TL;DR: In this article, a substantially mobile system for testing sour natural gas including vehicles allowing the equipment to be operated on surfaces such as the flat beds of trailers is presented, where equipment may be mounted within one or more support structures situated on a mobile vehicle, such as, for instance the flat bed of a trailer.
Abstract: The invention provides a method of testing sour natural gas by a) removing H2S from the gas stream, b) converting H2S to elemental sulfur, and c) recovering elemental sulfur. The invention also provides a substantially mobile system for testing sour natural gas including vehicles allowing the equipment to be operated on surfaces such as the flat beds of trailers. The system features equipment that may be mounted within one or more support structures situated on a mobile vehicle, such as, for instance the flat bed of a trailer. The one or more support structures hold each piece of equipment substantially fixed in place on the vehicles. Each surface such as the flat bed of a trailer may carry one, two or more pieces of equipment. The equipment may include, for instance, an air or oxygen compressor, a knockout vessel, a gas heater, an air heater, a cooler, a molten sulfur separator and a thermal oxidizer.

TL;DR: In this article, a steel ball recovery hopper was proposed to avoid the inconvenience that steel balls enter a flue at an outlet in a heat recovery device and are retained there when a dust removing operation is carried out by a shot cleaning without raising the construction cost of the heat recovery devices such as a gas heater.
Abstract: PROBLEM TO BE SOLVED: To provide a structure capable of avoiding an inconvenience that steel balls enter a flue at an outlet in a heat recovery device and are retained there when a dust removing operation is carried out by a shot cleaning without raising the construction cost of the heat recovery device such as a gas heater SOLUTION: A steel ball recovery hopper 18 having an inclined surface 17 with a downward grade from a lower end of an inlet 14a as an origin toward a downstream side of the flowing direction of exhaust gas GE is provided in a lower surface in the vicinity of the inelt 14a of an outlet flue 14 of a gas heater 2 as a heat recovery device A dust conveying line 19 branched from a part between a cut gate 8 and a dust separator 9 and extending upward is connected the lower end of the steel ball recovery hopper 18 Thus, steel balls 15 dropping on the steel ball recovery hopper 18 can be slid and dropped on the conveying line 19 and guided to the dust separator 9
