    Abstract: A tangible, non-transitory computer readable medium includes computer instructions stored thereon, the computer instructions, when executed by a processor, cause the processor to retrieve model inputs indicative of mechanical systems data, economic data, contractual data, regulatory data, or any combination thereof, associated with at least one compression system. Furthermore, the instructions cause the processor to retrieve a model that derives an operation schedule for the at least one compression system based on the model inputs. Then the instructions cause the processor to derive an operation schedule for the at least one compression system based on the model inputs and the model, and apply the operation schedule to the at least one gas compression system.

    Abstract: A system includes a nitrogen oxide reduction catalyst fluidly coupled to an exhaust conduit of an engine system. The nitrogen oxide reduction catalyst is configured to reduce nitrogen oxides in an engine exhaust. The system also includes an ammonia oxidation catalyst fluidly coupled to the exhaust conduit downstream of the nitrogen oxide reduction catalyst and configured to reduce ammonia in the engine exhaust. Further, the system includes a reductant injection control system configured to control an injection of reductant into the exhaust conduit, determine a first nitrogen oxide conversion rate of the nitrogen oxide reduction catalyst, determine an ammonia storage value of the nitrogen oxide reduction catalyst, and determine a first temperature of the engine exhaust upstream of the ammonia oxidation catalyst. The reductant injection control system is also configured to increase or decrease the injection of reductant based on the first nitrogen oxide conversion, the ammonia storage value, and the first temperature.

    Abstract: A system includes a controller programmed to monitor an oxidation state of a three-way catalyst (TWC) assembly coupled to a combustion engine. The controller is programmed to receive signals representative of oxygen (O2) concentration in a fluid both upstream of an inlet and downstream of an outlet of the TWC assembly, to receive a signal representative of the measured O2 storage of the TWC assembly from at least one radio frequency (RF) probe disposed within the TWC assembly, to utilize a model to generate an estimated O2 storage of the TWC assembly based at least on the O2 concentration in the fluid both upstream and downstream of the TWC assembly, to compare the estimated O2 storage to the measured O2 storage, and to output a control action for the TWC assembly based at least on the comparison of the estimated O2 storage to the measured O2 storage.

    Abstract: A system includes an exhaust aftertreatment system configured to treat emissions from a combustion engine. The exhaust aftertreatment system includes a selective catalytic reduction (SCR) catalyst assembly and at least one radio frequency (RF) probe disposed within the SCR catalyst assembly. A controller is coupled to the exhaust aftertreatment system and utilizes an NH3 storage estimate measured by the at least one RF probe and an NH3 storage estimate determined by an NH3 storage estimate model to output a control action for a reductant injection system. The NH3 storage estimate model utilizes measured concentrations of nitrogen oxides (NOx) in the fluid upstream or downstream of the SCR catalyst and/or measured concentrations of NH3 in the fluid upstream or downstream of the SCR catalyst, and the NH3 storage measurement from the at least one RF probe to determine the NH3 storage estimate.
