Improving sulphur recovery units - DigitalRefining

The incinerator combusts the tail gas stream from the SRU with sufficient oxygen, at the proper temperature, for a given residence time. Based on the tail gas composition from the SRUs and allowing for 10ppm of H2S in the incinerator tail gas, the incinerators at the Sinclair and Casper refineries were designed to be operated at 1250–1350°F

WHAT HAS YOUR SULPHUR PLANT DONE FOR YOU LATELY?

As shown in Figure 2, heat released in the process is recovered in the SRU waste heat boiler (WHB) as HP or MP steam, and in the sulphur condensers as LP or LLP steam. In addition to heat released by the Claus reaction, the incinerator produces heat via combustion of fuel gas to achieve temperatures hot enough to ensure complete oxidation of H. 2.

Rotary Kiln Incinerator - an overview | ScienceDirect Topics

Among the early waste-heat recovery incinerators were low-pressure boilers, high-pressure boilers, and water wall furnaces. Low-pressure boilers were the first to be developed and the majority of them had boilers located in the combustion chamber which lowered combustion efficiency as a result of excessive cooling of the furnace [49,58] .

Review of Techniques for Incineration of Sewage Sludge

The actual indirect drying operation is very much the same as the direct drying operation. Sludge is first premixed with previously dried solids (entering the dryer at about 50 percent moisture) and is dried to about 15 percent moisture. Steam generated in the incinerator waste heat boiler pro- vides the heat.

Downsizing a Claus Sulfur Recovery Unit

Waste Heat Boiler The boiler is a heat transfer device. There will be too much surface area within the boiler to maintain the original design outlet temperature. If the outlet temperature drops below the sulfur dew point of the boiler outlet stream, the sulfur will be condensed within the boiler. Some boilers have sulfur rundown legs and some
