It is attempt in pulverized coal injection (PCI) in blast furnace tuyeres to increase the injection rate without increasing the amount of unburned char inside the stack of the blast furnace. The unburned char can cause problems in the blast furnace operation, such as reduced permeability, undesirable gas/temperature distribution, excessive coke erosion and significant char carryover. In the nea...

As the main anthropogenic greenhouse gas that contributes most to global warming, CO2 plays an important role in climate changes in Central Asia. Due to the lack of studies of near-surface CO2 in this region, we first confirmed the applicability of the near-surface Greenhouse Gases Observing Satellite (GOSAT) CO2 data in Central Asia using atmospheric CO2 concentration data from nine ground-bas...

Carbon dioxide (CO2) injection has been used as a commercial process for enhanced oil recovery (EOR) since the 1970’s. Because the cost of oil recovered is closely linked to the purchase cost of the CO2 injected, considerable reservoir engineering design effort has gone into reducing the total amount of CO2 required to recover each barrel of oil. If, on the other hand, the objective of the CO2 ...

Controlled source electromagnetic transmitters create highly geometric coupled electric and magnetic vector fields that propagate in a way that is dependent on both the orientation of the transmitter and electrical conductivity distribution. There may be a good case for using cross well controlled source electromagnetic methods for monitoring injection of CO2 into deep saline or brackish sandst...

The injection of carbon dioxide (CO2) in deep, unmineable coalbeds is a very attractive option for geologic CO2 storage: the CO2 is stored and at the same time the recovery of coalbed methane (CBM) is enhanced. The revenue of methane (CH4) production can offset the expenditures of the storage operation. Coalbeds form complex gas reservoirs characterized by their dual porosity: they contain both...

Proper handling of produced sour gas is a big challenge for operating companies due to the serious environmental and technical problems caused by H2S. Among various processing methods, reinjection into reservoirs cost-effective environmentally-friendly technique that not only enhances oil recovery but also allows underground storage The high safety requirements working with toxic H2 S have supp...
