20090010834 | Process for the Thermal Reduction of Sulfur Dioxide to Sulfur - Processes for the thermal reduction of sulfur dioxide to elemental sulfur are described and disclosed. The processes described include three general reaction sections, including the reaction furnace portion where the SO | 01-08-2009 |
20100178236 | Sulfur Collection Systems and Processes with Integrated Degassing - Systems and methods for the collection of liquid sulfur with integrated degassing are described, wherein the system and methods include the use of one or more liquid jet pumps or eductors employing a pumped liquid sulfur recycle stream as motive fluid to boost sulfur rundown pressure. The new invention eliminates piping constraints inherent with conventional gravity flow, thus permitting location of the sulfur collection vessel above ground and remote from the sulfur recovery unit. In addition, the described methods provide entrainment and enough agitation in the liquid sulfur such that simultaneously degassing occurs within the sulfur collection piping and associated systems described herein. The instant systems and methods are integrated with the degassing system, meaning that the sulfur will be initially degassed during the collection process, and then further degassing occurs by the methods described herein. | 07-15-2010 |
20120308474 | Process for The Production of Sulfur from Sulfur Dioxide with Tail Gas Recycle - The reduction of the gas stream containing sulfur dioxide to elemental sulfur is carried out by reacting a reducing gas, such as natural gas, methanol or a mixture of hydrogen and carbon monoxide, with recycled sulfur and recycled tail gas to produce a stream containing hydrogen sulfide that may be reacted with the gas stream that contains sulfur dioxide. Gas streams with a molar concentration of sulfur dioxide from 1 to 100% may be processed to achieve nearly 100% sulfur recovery efficiency. | 12-06-2012 |
