1 The flexibility of using the same process scheme for any make-up gas
任意補充氣采用相同工藝方案的靈活性
2 Use of COG in an ENERGIRON plant
ENERGIRON直接還原廠使用焦爐煤在氣
3 EXPERIENCE WITH COG FOR DIRECT REDUCTION
使用COG進行直接還原的經(jīng)驗
EXPERIENCE WITH USE OF COG IN ENERGIEON PROCESS
ENERGIRON工藝中使用COG的經(jīng)驗
The patented scheme by TENOVA has been tested under the following scenarios:
① Pilot plant tests; campaigns in 1978-1982, 1997.
②Laboratory tests at AHMSA BF, Mexico to prove destruction of BTX with hot DRI in 1980's.
③Tests carried out at Zdz, Poland in a joint effort between ArcelorMittal and Tenova HYL in 2008. As results of the tests of BTX in the COG, 95-980% of BTX was gasified for various concentrations: -0.5-0.7 g/Nm3; 4.0 g/Nm3 and 20.0 g/Nm3.
④Successful results confirmed the technical feasibility of the ENERGIRON ZR patented scheme for use of COG.
該專利方案由特諾恩在如下情況下己完成測試:
①試驗工廠測試;分別于1978-1982, 1997
②實驗室測試:于20世紀80年代在墨西哥AHMSA BF,熱態(tài)DRI,驗證苯的裂解
③于2008年,由特諾恩和阿賽洛米塔爾共同在波蘭Zdz進行測試,COG中如下不同濃度的苯的裂解,95-98%的苯被氣化:0.5-0.7 a/Nm3: 4.0 a/Nm3 and 20.0 a/Nm3
④成功的試驗結(jié)果確認了ENERGIRONZR專利方案使用COG的技術(shù)可行性。
4 TYPICAL PROCESS PARAMETERS WITH COG/NG
使用COG/NG的典型工藝參數(shù)
5 CO2 proven Absorption system when using NG or COG
使用NG或COG時成熟的CO2吸收系統(tǒng)
CO2 ABSORPTION SYSTEM
CO2吸收系統(tǒng)
1) In a DRP, CO2 emissions are related to iron ore reduction and carbon content of the fuel used (Coal, NG, etc).
2)ENERGIRON DR process intrinsically includes a CO2 absorption system for selective elimination of C02.
1) 在直接還原廠,二氧化碳排放是與鐵礦還原和所使用的燃料(煤、天然氣等)的碳含量息息相關的。
2)ENERGIRON直接還原工藝獨有的二氧化碳吸收系統(tǒng)可以選擇性的脫除二氧化碳。
