20120023905 | SYSTEM, METHOD, AND APPARATUS TO ENGAGE ALTERNATE REDUCTANT IN A NOX REDUCTION SYSTEM - An exhaust aftertreatment process including providing a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an internal combustion engine; determining that a temperature of the exhaust stream is not within an NH | 02-02-2012 |
20120023906 | SYSTEM AND APPARATUS FOR ENHANCING EXHAUST AFTERTREATMENT STARTUP EMISSIONS CONTROL - An aftertreatment system including a method which provides a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an engine; determines that an ammonia pre-load condition for the SCR catalyst is present; determines a first amount of ammonia pre-load in response to the ammonia pre-load condition; injects an amount of ammonia or urea into the exhaust stream in response to the first amount of ammonia; and adsorbs a second amount of ammonia onto the SCR catalyst in response to injecting an amount of ammonia or urea, where the second amount of ammonia is either the injected amount of ammonia or an amount of ammonia resulting from hydrolysis from the injected amount of urea. | 02-02-2012 |
20120245737 | REAL-TIME CONTROL METHOD AND GAS PURIFICATION SYSTEM FOR SOLVENT BASED CAPTURE SYSTEMS - Gas purification systems generally include an analyzing unit including a plurality of sensors and/or probes for continuously analyzing a solvent cyclic capacity in real time, the plurality of sensors and/or probes in fluid communication with rich amine and lean amine solution carrying conduits and the water wash conduits; and a system control unit configured to receive outputs from the analyzing unit for monitoring and controlling the solvent cyclic capacity in real time. Also disclosed are computer implemented methods for providing the real time control. | 09-27-2012 |
20130101486 | ON-LINE MONITORING AND CONTROLLING OF SULFUR COMPOUNDS IN POWER GENERATION FACILITIES FOR CARBON DIOXIDE CAPTURE PROCESSES AND ARTICLES COMPRISING THE SAME - An online monitoring and controlling system is used for monitoring and controlling sulfur content in heat stable salts or in a flue gas stream. The system comprises valves, sensors and analyzers that are operated by a valve flow and control system that regulates the valves to redirect flow of the heat stable salt or the flue gas stream to reduce the sulfur to below a desirable value. The valve and flow control system is automated and uses a feedback loop to control the sulfur content. | 04-25-2013 |
