Boiler blowdown - Lenntech

Boiler blowdown wastewater treatment In any case, the temperature, the pH and level of dissolved solids at least of the blowdown water must be adjusted before going to sewers. In specific cases, it can also be interesting to reuse the blowdown waste water especially in some areas where water is scarce.

Temperature moderation with water of an oxygen enriched claus …

The reactor furnace effluent then passes through a circuitous heat exchange zone or waste heat boiler 24 wherein the combustion effluents are cooled against boiler feed …

New insights into Claus waste heat boilers

New insights into Claus waste . heat boilers. The real plant performance of a waste heat boiler depends on many factors besides heat transfer. The Claus waste heat boiler (WHB) is a critical piece of equipment in the sulphur recovery unit (SRU). As processors move towards higher sulphur feedstocks, more load is placed on the SRU, and WHB

Simulation of Claus unit performance - DigitalRefining

• With oxygen enriched air, furnace temperatures can become high enough to exceed the thermal limits of the furnace's refractory and of the material in the waste heat boiler, especially with regard to corrosion. In the original case, 28.5% enriched air resulted in a

@article{osti_6817940, title = {Recycling of waste heat boiler effluent to an oxygen-enriched claus reaction furnace}, author = {Pendergraft, P T and Bond, G M}, abstractNote = {A method of recovering sulfur from a feed gas stream containing hydrogen sulfide combusted with an oxygen-enriched gas in a Claus reaction furnace zone is described, comprising: dividing combustion effluent as it is

Claus waste heat boiler economics Part 1: process considerations

A process and system are set forth for improving an oxygen-enriched Claus plant by recycling effluent from the first condenser back to the reaction furnace to moderate oxygen induced high temperatures and thus allow additional oxygen-enrichment and attendant

Effect of O2 Concentration on the Reaction Furnace Temperature and Sulfur Recovery …

The effluent gas from the main burner (reaction furnace) passes through the first pass waste heat boiler (1 st pass WHB) to recover heat and produce high pressure steam [1,6]. The second pass of the waste heat boiler is where the redistribution of S 2 to S

Modeling reaction quench times in the waste heat boiler of a …

A portion of the effluent from the waste heat boiler 14 is recycled into the Claus reaction furnace 12 to moderate the temperatures therein as desired in the following manner. A valve or a T connector is connected to line 19 to pass a portion of the effluent through a line 42, a throttling valve 44, to a …

US Patent for Temperature moderation of an oxygen enriched …

In the waste heat boiler 24 the reaction effluents are converted from one form of sulfur species to another according to the following equations: S 2 → 1/3 S 6 S 2 → 1/4 S 8 The cooled effluent from the waste heat boiler in line 30 is at a temperature of 316 C (600

New insights into Claus waste heat boilers T he Claus waste heat boiler (WHB) is a critical piece of equipment in the sulphur recovery unit (SRU). As processors move towards higher sulphur feed-stocks, more load is placed on the SRU, and WHB failures are

Sulphidation corrosion in a claus waste heat boiler

Oxygen enrichment also can have a profound effect on heat flux and capsize a border-line issue into a catastrophic failure. Sulphidic corrosion is generally calculated based on the widely accepted Couper-Gorman curves1 which, at least for high heat fluxes, have been very closely confirmed by measurements made by Alberta Sulphur Research Limited (ASRL) for carbon steel.
