Nitrogen Oxides (NOx) and Dioxin removal contained in flue-gas leaving combustion processes, to meet the most stringent environment regulations concerning atmospheric pollution. The De NOx…
Catalytic purification of Claus tail gas or lean H2S waste gas for an overall sulfur recovery ranging from 99% to 99.9%. Different versions of the…
A low-pressure drop, high-sulfur recovery efficiency process to recover sulfur components from tail gas of sulfur plants. The SCOT process is insensitive to variations in…
Purification of sulfur recovery unit (SRU) tail gas for incineration. Resulf, Resulf-10 and Resulf-MM units are easily retrofitted to existing SRU complexes. They feature a…
Wet-scrubbing process purifies Claus tail gas for total sulfur recovery ranging from 99.8% to 99.9+%. Description: The optimum Claus tail-gas treatment converts sulfur species to…
Claus tail-gas treatment with total sulfur recoveries up to 99.9+%. Liquid-phase conversion of H2S and SO2 into liquid elemental sulfur (S). Claus tail gas is…
Purify tail gas from sulfur recovery units (such as Claus units) and other gas streams containing low concentrations of SO2. The type of process to…
AMMOGEN provides gaseous ammonia to fossil-fuel-burning plants to operate pollutioncontrol systems such as DeNOx/DeSOx SCR, SNCR and flue-gas treatment units. This process produces gaseous ammonia…
Treat any gas for dehydration, hydrate protection, dew-point control and acid-gas removal, using a single, low-freezing point solvent—methanol. Ifpexol is a two-step process; each step…
