Two basis types of synthesis gas obtainment units are found in the major part of domestic ammonia production plants. One of the systems includes primary reformer, secondary reformer and a heat recovery subsystem (ZAT, ZCh Police, ZAW, Puławy II). The other one consists of natural gas cracker and heat recovery subsytem (ZAK, Puławy I). The main controllable parameter at the inlet of the above mentioned units is C/H2O ratio. Entire cost of the synthesis gas obtainment is also influenced by prices of the raw materials (natural gas, steam, oxygen), as well as by the equipment design. Following computer implementation, mathematical models of the above mentioned equipment arising from our own investigations have been included to the "TAWAS" package [1], which enabled to analyse performance of the sections by computer simulation. The results obtained have provided both the guidelines to offers for modernization of the synthesis gas obtainment sections and the data to operate the existing.
