Computer modeling has been used to provide more detailed information about the alternative catalyst-free methane-oxygen reformer for a small scale gas-to-liquid module. The basic input data include 3-MPa process pressure, oxygen as oxidizer, and oxidizer/fuel equivalence ratio about 3 to provide H 2 to CO ratio ≥1.7 needed for further direct liquefaction via Fisher-Tropsch processing. As a result, a reasonable temperature level of the reformer walls has been achieved that makes possible its engineering as the next step.

“…The combustor of a 25 MW power gas turbine engine has a cannular design (Fig. 4) in which dry combustion of a lean partially premixed mixture is carried out [29,30]. The main element of this chamber is a burner consisting of two radial swirlers, one for each of the two channels, behind which the annular mixing chambers are located.…”

In this paper, we consider the issue of thermo-chemical heat recovery of waste heat from gas turbine engines for the steam conversion of associated gas for offshore vessels. Current trends in the development of offshore infrastructure are identified, and the composition of power plants for mobile offshore drilling units and FPSO vessels is analyzed. We present the results of a comparison of power-to-volume ratio, power-to-weight ratio and efficiency for diesel and gas turbine power modules of various capacities. Mathematical modeling methods are used to analyze the parameters of an alternative gas turbine unit based on steam conversion of the associated gas, and the estimated efficiency of the energy module is shown to be 50%. In the modeling of the burning processes, the UGT 25000 serial low emission combustor is considered, and a detailed analysis of the processes in the combustor is presented, based on the application of a 35-reaction chemical mechanism. We confirm the possibility of efficient combustion of associated gas steam conversion products with different compositions, and establish that stable operation of the gas turbine combustor is possible when using fuels with low calorific values in the range 7–8 MJ/kg. It is found that the emissions of NOx and CO during operation of a gas turbine engine on the associated gas conversion products are within acceptable limits.

Investigations of the working processes in a gas turbine low-emission combustor operating on the synthesis gas, in which the principle of RQL (Rich-Burn, Quick-Mix, and Lean-Burn) combustion technology is realized, have been performed. Selected concept of a gas turbine combustor can provide higher performance and lower emission of nitrogen oxides and demonstrates satisfactory major key parameters. Obtained results and recommendations can be used for the gas turbine combustor operation modes modeling, geometry optimization, and prospective power generation units design and engineering.
