Basic Description: iron oxide desulfurizer [1] based on iron oxide as the main active component, adding other accelerators from the processing of highly efficient gas purifying agent. Between 20 ° C to 100 ° C, the hydrogen sulphide has a high removal performance, and also have a certain thiols, organic sulfur, and most of the nitrogen oxides removal effect. Properties and Uses: iron oxide sorbent its sulfur content, low prices, welcomed by users regeneration air at room temperature. But there are inadequacies intensity difference, case gouache, desulfurization accuracy is not high (1 ppm), and its industrial application. In response to these circumstances, our technical staff after several years of painstaking research, development HYF series of new iron oxide sorbent, which is characterized by: 1, desulfurization high precision: the imports H2SI1000ppm, export H2S 0.05ppm than ordinary Fe2O3 desulfurization accuracy ( 1ppm) 20 times; 2, the reaction speed: 1000-20000h-1 space velocity 3-6 times higher than the average Fe2O3; 3 work (Penetrativity) sulfur capacity: 1 and 2 under the conditions of time sexual fine O2 H2S removal sulfur content of 15-20%, which is 3-6 times of ordinary Fe2O3 desulfurizer. 4, good strength, good water resistance. Boiled 2h or powder soak for 30 days, the same intensity. 5, a temperature range of 5 to 90 ° C wide, can be applied in no O2 or high CO2 conditions. Anaerobic fine H2S removal sulfur contents of 12-15%. Fine off the desulfurizer for gas, water gas, semi-water gas, air gas, coke oven gas, the shift gas CO2 angry, food CO2, steel mills feed gas, methane gas, petrochemical and other gas H2S, with hydrolysis The 504 catalyst supporting the use of H2S + CO2 ≤ 0.06ppm, to make up for the lack of activated carbon fine desulfurizer, iron oxide sorbent new technology more widely used. Edit this paragraph reaction principle desulfurization and regeneration reaction principle is as follows: 2Fe (OH) 3 XH2O +3 H2S-Fe2S3 · XH2O +6 H2O (desulfurization) Fe2O3 XH2O +3 H2S = Fe2S3 · XH2O +3 H2O (desulfurization) Fe2S3 = 2FeS + S above reaction (mostly decomposition) Fe2O3 · xH2O + O2 = Fe2S3 · XH2O +3 S (reproduction) 2FeS + O2 + XH2O = Fe2O3 · XH2O +2 S (reproduction), such as the gas source O2/H2S greater than 3, the desulfurization and regeneration reaction can be carried out simultaneously, showed a higher sulfur capacity, or after a certain time after desulfurization need to pass air fresheners.

Edit this paragraph iron oxide sorbent Instructions 1, the filling Desulfurizer filled with good or bad directly affect the results, you must pay sufficient attention to, throughout the desulfurizer loading process should be the person responsible, and note the following: 1) in the desulfurization tower grid The grate plate laying Layer 2 mesh less than 8-10 mesh stainless steel mesh. (2) on the fence, and then laying a layer of 20-30mm, Φ20-30mm thick broken coke block. (3) the transport, loading and unloading will generate dust, sifting before filling. (4) the use of a special filling tool, the discharge pipe should be able to rotate freely, so that the material can be uniformly packed around the reactor, non-desulfurizing agent poured from the middle to prevent loading coloring. (5) desulfurizer with suction during use of sulfur content increases with increasing intensity, and therefore should be layered filling in the desulfurization tower. Each floor filled with a high degree of desulfurization agent crossed the installation of foot, installed flat, fitted uniform. (6) the filling process, is strictly prohibited directly stampede sulfur agent, wooden pad on the material layer, re-entering the Grilled materials and check the filling. (7) desulfurization entrance of the feed gas, should be installed on the grid the grate plate or broken coke block to prevent disperse the desulfurizer. The desulfurization tower 2, using (1) ships having specialized heating energy consumption, but must be insulated to the desulfurization apparatus in an outdoor winter, so that the gas is subcooled, reduced water activity and bed desulfurizer and degraded operation. (2) desulfurization before trying to remove the tar and water droplets. (3) The desulfurizer to replace all paragraph by paragraph, replace, according to the direction of air flow. (4) Timing emissions the desulfurization tower water separator and the bottom of the desulfurization tower stagnant water, non-gas with liquid into the desulfurization tower. (5) The operation should be stable, use should be reasonable, in order to play its excellent performance. , Transportation (1) desulfurization agent in the transport to gently put, avoid knocks and bumps, so as to avoid damage. (2) desulfurization agent in the custody period, to prevent suction of ridicule and chemical pollution. Edit this paragraph desulfurizer regeneration desulfurization tower gas exports exceed 1 ppm H2S or usage requirements indicators, and the sulfur capacity has not been to the specified target, the regeneration of the desulfurization agent. 1, the regeneration method: can be divided into continuous regeneration and intermittent renewable. When a raw gas O2/H2S (molar ratio) of up to 3 hours, continuous reproduction can be realized without special reproduction operation. Such as low oxygen content of the raw gas, the continuous reproduction can not be achieved when the intermittent regeneration, the intermittent regeneration is generally in the following ways: (1) an inert gas with air recycled; (2) an inert gas with air recycling; (3) through natural air fresheners; (4) forced through the air regeneration; 2, the regeneration process control the sharpness of the bed 30 to 70 ° C, the maximum can not exceed 90 ° C, the temperature control method for adjusting the oxygen content. The naturally through air fresheners, mainly for the smaller amount, to suck less sulfur occasions, the temperature control is mainly used to adjust the oxygen content, the temperature soared intake valve should be closed immediately. 3, the regeneration time required to vary depending on how much of the sulfur absorption amount. Sulfur absorption and regeneration process; less sulfur absorption, short regeneration process. 4, the frequency of regeneration is generally 2-3 times. 5, the end of the regeneration flag: When the bed temperature does not rise, the import and export of the oxygen content is basically the same to the end of the regeneration.
