Abstract: An ammonia production process comprises steam hydrocarbon primary reforming, air secondary reforming, carbon monoxide shift, carbon oxides removal, ammonia synthesis and discarding of non-reactive gases and is made more economical in energy consumption by using excess air in secondary reforming and treating the synthesis gas to separate a hydrogen-enriched stream and returning that stream to the synthesis. Preferably the synthesis gas after carbon oxides removal is compressed if at all by no more than 50% and consequently the process can be carried out in a plant having a gas circulator but no compressor. Preferably synthesis is at a pressure in the range 40-80 bar abs. and at an outlet temperature in the range 350-430° C over a catalyst containing iron, cobalt and promoting compounds. Recovery of the hydrogen-enriched stream is preferably from a side stream of synthesis gas.

Abstract: An improved process for the separate recovery of substantially pure ammonia and substantially pure carbon dioxide from mixtures containing ammonia and carbon dioxide, and possibly water, such as are obtained as by-products in the manufacture of melamine from urea or the synthesis of urea from ammonia and carbon dioxide. The by-product mixture is introduced into a process loup having an ammonia separation zone (1) with a NH 3 - rectifying column (3), a carbon dioxide separation zone (2) with a CO 2 - rectifying column (18). and a desorption zone (3) where virtually all NH 3  and C0 2  are removed in desorber (10), the zone to which the mixture is initially fed being dependent upon its composition. The separation is effected by maintaining a system pressure differential between the ammonia and carbon dioxide separation zones, or adding diluting water to the carbon dioxide separation zone. The efficiency of the separation is enhanced by introducing an ammonia containing gaseous phase into the bottom of the carbon dioxide separation zone.

Abstract: An operational amplifier (33) is continuously switched back-and-forth between an auto-zero mode of operation and an accurate amplification mode of operation. During the auto-zero mode of operation, the junction between an offset voltage compensation (eg., auto-zero) capacitor (35) and the noninverting input of the operational amplifier (33) is referenced to the input signal voltage via a bootstrap amplifier (31), rather than being tied to ground. Further, during the auto-zero mode of operation, the other end of the auto-zero capacitor (35) is referenced to the output of the operational amplifier (33), which is also connected to the inverting input of the operational amplifier. As a result, the auto-zero capacitor (35) is charged to a voltage level equal to the input offset voltage of the operational amplifier, but in polarity opposition thereto. During the accurate amplification mode of operation, the input signal is applied to the noninverting input of the operational amplifier (33) via the auto-zero capacitor (35). As a result, the charge on the auto-zero capacitor cancels the input offset voltage of the amplifier whereby the output of the operational amplifier (33) is accurately related to the voltage of the input signal by the gain of the operational amplifier. Because the auto-zero capacitor (35) is referenced to the input signal voltage during the auto-zero mode of operation, rather than being tied to ground, voltage swings at the output of the operational amplifier (33) and across the various switch elements (37, 39, 41) are kept low. As a result, the auto-zero amplifier circuit is operable over a wide dynamic range.
