摘要： A method and assembly for separating contaminants from liquids, such as condensates, or vapors at an evaporation plant. The contaminants are separated from liquids by stripping when bringing a contaminant-enriched liquid into direct contact with a vapor by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus reducing the contaminant-content of the sprayed liquid and producing a cleaner liquid. The contaminants are enriched in the vapor. From vapors contaminants are separated by absorption when bringing a contaminant-enriched vapor into direct contact with a cleaner liquid by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus increasing the contaminant-content of the liquid, but producing a cleaned vapor.

摘要： A circular utilization method in pulping and papermaking processes with straw Primary pulp is obtained by digesting straw raw material according to the ammonium sulfite method. Concentrated black liquor is extruded from the primary pulp; paper pulp and diluted black liquor. The concentrated black liquor and the diluted black liquor are mixed, and a contaminated condensate is obtained. A residual concentrate or the concentrated black liquor is used for preparing a fertilizer. The contaminated condensate is mixed with one or more of the waste material obtained from stock preparation, a crop byproduct or organic waste, and substrate or fertilizer is obtained by fermenting the nitrogen source of the contaminated condensate or ammonium sulfite, or using the contaminated condensate for desulfurizing flue gas. Ammonia and flue gas are reacted to obtain the ammonium sulfite as a digestion agent; and water from recycling is used in corresponding phases of the pulping process.

摘要： By the utilization of a jet ejector (such as a thermocompresser) in a cellulose chemical pulp mill, it is possible to effectively increase the utilization of steam. The volume of steam from a flash tank which flashes black liquor from a pulp digester may be increased (e.g. at least about 10%), while the volume and temperature of the liquor discharged from the flash tank are decreased and its concentration increased, by operatively connecting the jet ejector to the steam discharge from a flash tank. The jet ejector is supplied with higher pressure steam from another source which can result in a low pressure or partial vacuum condition in the flash tank. The flash tank may be a single flash tank or one of a series of flash tanks, and an ejector can be associated with at least another flash tank in the series. The hot spent cooking liquor from the digester can be cooled in a heat exchanger (for example in indirect heat exchange relationship with a fresh cooking liquor) prior to introduction in to the flash tank or series of flash tanks. Alternatively a jet ejector may be used to increase the pressure of a low pressure steam flow in a pulp mill to make it suitable for alternative uses.

摘要： An apparatus and method for sulfur recovery uses a scrubber tower with a plurality of vertically spaced scrubber trays in the tower. Sulfide-lean liquor is supplied to each of the trays and an acid gas is supplied to the tower below the trays. A downcomer extends in the tower and through the trays for accumulating liquid from the trays and moving the liquid to the bottom of the tower. The sulfide-lean liquor and acid gas are selected to form a sulfite-rich or sulfide-rich liquor in each of the trays which are brought to the bottom of the tower through the downcomer for removal from the tower.
