9. Can heavy metals or poisonous gases be formed in the Blue Tower and how would this be controlled?
No. Heavy metals can get into the process as a component of the input material only. There is no chance heavy metals are formed within the process. In special cases, if the input material is highly heavy metal laden, the pyrolysis char combustor may be designed and operated in a way that heavy metals are held firmly in the molten and afterwards solidified ash. The carbon monoxide gas is an essential product of every gasification plant. It is combustible and consequently, an energy carrier. It is an important component of the synthesis gas and hence of high value. Unfortunately, carbon monoxide (CO) is poisonous. Therefore, both at the Blue Tower and in subsequent applications, the product gas is handled in a way completely separated from the atmosphere and hence, no CO and other components of the product gas are set free. The same is true for hydrocarbon species formed during pyrolysis. They are destroyed to a far extent in the Blue Tower within the reformer by adding of vapor with high temperatures - up to 950 °C.
