Process for the regeneration of arsenic-contaminated sorbents

In the selective catalytic removal of nitrogen oxides from flue gases of slag-tap-fired furnaces, in particular those having ash recycling, the problem occurred that the catalysts based on titanium oxide were rapidly deactivated by arsenic compounds. The catalysts thus damaged previously had to be replaced by new ones. On the other hand, there is the possibility of removing in advance the arsenic compounds from the flue gas by a titanium oxide-based sorbent provided upstream of the catalyst. It is thus desirable to find a process for the regeneration of arsenic-laden sorbents. Arsenic-laden sorbents can be regenerated by washing with an inorganic or organic acid.

Method for regenerating and inerting the absorber units, the molecular sieve and further appliances in an installation for the dry recovery of solvents, and installation for implementing said method

In order to achieve rapid and safe regeneration and inerting of the adsorber units, the molecule sieve and further appliances forming part of an installation for the dry recovery of solvents from a gas stream, at the start of the initiation of regeneration a reduced pressure is generated by evacuation, and said reduced pressure is then cancelled out by adding an inert gas into the system. By repeating this process several times, rapid and extensive inerting of the installation is achieved. Finally, in order to regenerate the molecular sieve the heated gas stream used for this purpose after passing through the molecular sieve is discharged into the atmosphere, so as to preclude entirely the reentry of humidity into the installation. The regeneration of the molecular sieve, according to the invention, uses heated air as the heated gas stream. ...

PROCESS AND PLANT FOR REGENERATING ABSORBENTS USED FOR THE CAPTATION OF SULFUR DIOXIDE IN COMBUSTION FUMES

Fluid bed desulfurization

A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is than separated from a desulfurized effluent gas and regenerated by contact with an oxygen-containing gas in a transport riser. The regenerated sorbent is separated from an SO2 containing offgas and recycled to the desulfurization step. The degree of sorbent conversion in the desulfurization step is held at a low level and the sorbent regeneration rate is increased to avoid excessive temperature rise in the regeneration step. In such manner, sorbent cooling can be substantially eliminated. The regeneration riser preferably comprises a once-through lift riser to minimize the riser transport gas requirements to just oxidant gas or oxidant gas mixed with a reduced amount of diluent gas. A reduction in use of diluent gas give a relatively high offgas SO2 concentration of as much as 15 mole percent, suitable for sulfuric acid manufacture and/ or reduction to sulfur.

Method for recovering vivianite from sludge incineration ash

The present invention relates to a method for recovering vivianite from sludge incineration ash, comprising the following steps: (1) mixing sludge incineration ash with acid liquor, heating to leach phosphorus, and then performing filtering and separating to obtain leached filtrate and leached filter residues; (2) adjusting the pH value of the leached filtrate with alkali liquor, adding an adsorbent for phosphorus adsorption, and then performing filtering and separating to obtain adsorbed filtrate and adsorbed filter residues; (3) mixing the adsorbed filter residues with alkali liquor to perform phosphorus desorption, and then performing filtering and separating to obtain desorbed filtrate and desorbed filter residues; and (4) in an anaerobic environment, adding ferrous ions into the desorbed filtrate, adjusting the pH value of the desorbed filtrate to carry out reaction, then performing filtering and separating to obtain filter residues and filtrate, and washing and drying the filter residues to obtain vivianite. Compared with the prior art, the present invention eliminates the interferences of other elements in the sludge incineration ash, obtains a high-quality vivianite product, can alleviate the problem of phosphorus resource shortage, and is simple in technological process and convenient in operation.

A kind of method of phase transformation regulation and control recycle-water cationic heavy metal

本发明属于污水处理技术领域，公开了一种相变调控回收水中阳离子重金属的方法。将纳米吸附材料加入到含有阳离子重金属的污水中吸附后得到吸附有阳离子重金属的纳米吸附材料泥浆；然后将所得泥浆与水加入到反应器中，密闭及搅拌条件下通入CO 2 气体进行反应，使纳米吸附材料生成可溶性的碳酸氢盐由固相转移至溶液相，然后通过加热转化为固相的碳酸盐或碱式碳酸盐，经煅烧或干燥研磨，得到再生的纳米吸附材料。同时阳离子重金属与CO 2 及水存在的条件下反应生成不溶性沉淀。本发明的方法消耗物料为二氧化碳，不引入新的杂质，可实现阳离子重金属的富集回收和纳米吸附材料的再生回用。
