  "heading": "In order to improve the general environmental performance of the combustion of gaseous and/or liquid fuels on offshore platforms, BAT is to use one or a combination of the techniques given below.",
  "text": "Techniques\nDescription\nApplicability\na.\nProcess optimisation\nOptimise the process in order to minimise the mechanical power requirements\nGenerally applicable\nb.\nControl pressure losses\nOptimise and maintain inlet and exhaust systems in a way that keeps the pressure losses as low as possible\nc.\nLoad control\nOperate multiple generator or compressor sets at load points which minimise emissions\nd.\nMinimise the ‘spinning reserve’\nWhen running with spinning reserve for operational reliability reasons, the number of additional turbines is minimised, except in exceptional circumstances\ne.\nFuel choice\nProvide a fuel gas supply from a point in the topside oil and gas process which offers a minimum range of fuel gas combustion parameters, e.g. calorific value, and minimum concentrations of sulphurous compounds to minimise SO2 formation. For liquid distillate fuels, preference is given to low-sulphur fuels\nf.\nInjection timing\nOptimise injection timing in engines\ng.\nHeat recovery\nUtilisation of gas turbine/engine exhaust heat for platform heating purposes\nGenerally applicable to new combustion plants.\nIn existing combustion plants, the applicability may be restricted by the level of heat demand and the combustion plant layout (space)\nh.\nPower integration of multiple gas fields/oilfields\nUse of a central power source to supply a number of participating platforms located at different gas fields/oilfields\nThe applicability may be limited depending on the location of the different gas fields/oilfields and on the organisation of the different participating platforms, including alignment of time schedules regarding planning, start-up and cessation of production",
