CONDOR – Applications
Chemical thermodynamics began to be applied to industrial chemistry in the late 19th and early 20th centuries. The Bosch-Haber ammonia synthesis is the outstanding example of such applications and led to the Nobel Prize in Chemistry for Haber in 1919 and for Bosch in 1933. Haber’s book Thermodynamics of Technical Gas Reactions, first published in Munich in 1905 and later published in English in 1908 with some additional material, describes how chemical thermodynamics began to be applied to industry, although his seminal work on ammonia synthesis was done later and is not described in detail in this book. However, Haber’s work on ammonia synthesis is described in a chapter by Topham (1985) and in lesser detail in his 1919 Nobel Prize lecture.
Below are several examples showing applications of the CONDOR code to various problems in industrial chemistry.

Prior to the exploitation of natural gas, fuel gases were manufactured by blowing air-steam mixtures through a bed of hot coke. This gas is known as producer gas. The example below compares the composition of a typical producer gas to that predicted by the CONDOR code. The air-steam mixture (82.55 % air, 17.45 % steam) is blown through hot coke (assumed to be pure graphite) at 700 ºC and 1 atmosphere pressure. The gas compositions are given in volume percent.
