Before and after the desulfurization process; total sulfur, pyritic sulfur, carbon content and calorific value were measured. The highest removal efficiencies of total sulfur and pyritic sulfur for Burdur coal obtained as 41% and 67%, for Tunçbilek coal obtained as 41% and 35%, and for Ermenek coal obtained as 47% and 41%, respectively.

Wet flue gas desulfurization is widely used in power plants because of its high desulfurization efficiency. The reason why it is difficult to predict sulfur dioxide removal efficiency in flue gas is that it is related to many factors. In this paper, the SO2 was removed by absorbing with ammonia solution in a packed tower. Experimental studies have shown that the operating conditions affecting ...

A process flow diagram for the HDS plant is shown in Fig. 1. Desulfurization reactions take place in fixed bed catalytic reactors (∆ R) where a minimum ratio H 2 /hydrocarbon must be ensured for catalyst maintenance reasons. Reactors are fed with a blend of fuels of different qualities. The hydrocarbon (HC) feed is mixed with the recycled H 2 stream (R) and with makeup H 2 from the network.

Inbed desulfurization involves the use of Cabased sorbent, which captures in situ the SO2 emitted during fluidized bed combustion. Although this high temperature desulfurization process is well proven, the reduction of sorbent consumption is required to minimize the costs for sorbent and residue management.

The coal hydrogen production process requires hightemperature steam as a reactant. Coalfired boilers are usually used to provide hightemperature steam. The ammoniabased desulphurization process is an effective technology to remove SO2 in the coalfired flue gas. However, the mass transfer coefficient of SO2 in such an engineered process is not readily available in the literature. In this ...
