Seawater flue gas desulfurization is a desulfurization process that utilizes the natural alkalinity of seawater to absorb SO2 in flue gas. Figure 1 is the typical schematic diagram of SWFGD system. In this process, the following main reactions occur in the contact of SO2 with seawater in the flue gas: SO2 (gas) + H2O → H2SO3 → H+ + HSO3-(1The flow chart of the general ZLD system is shown in Fig. 1.

Study on the pyrolysis treatment of HPF desulfurization wastewater
The maximum desulfurization wastewater treatment capacity of the 4.3 m single riser was 61.98 kg h −1. The spraying optimization conditions were: spraying position, 3 m from the water seal cap of the riser; spraying amount, 50–55 L h −1; spraying time, from 10 min after the coal loading to less than 20 h during the coking process. AnThe image below is a schematic depiction of the equipment and the process flow streams in a typical refinery HDS unit: The liquid feed (at the bottom left in the diagram) is pumped up to the required elevated pressure and is joined by a stream of hydrogen-rich recycle gas. The resulting liquid-gas mixture is preheated by flowing through a heatHydrodesulfurization IDC-Online
