Abstract: A system for optimizing start-up of an amine regeneration system comprising a rich/lean heat exchanger, a still, a reflux condenser, a reflux accumulator, a pump, a reboiler, and a reflux accumulator fill line assembly.

Abstract: A method and apparatus for producing an inert gas is described. Firstly, capture the exhaust from a gas fired internal combustion engine located on the site of an intended application. Secondly, pass the exhaust stream through at least one catalytic converter. Thirdly, cool the exhaust stream passing from the catalytic converter to a temperature that will not harm a gas compressor. Fourthly, pass the exhaust stream into the gas compressor and apply the compressed exhaust stream exiting the compressor directly to the intended application.

Abstract: A closed loop controller and method of operation are provided which allow for configuring the controller with two switches. In one mode of operation, the two switches (22) and (24) are manipulated to increase and decrease the integral time value and the proportional gain, respectively, of the controller (10). In another mode of operation, the first switch (22) is manipulated to select among a plurality of configuration parameters and the second switch (24) is manipulated to select the desired value of the selected parameter. Level shifting circuitry (14) is also provided to permit remote operation of the controller (10) using a modem.
