Common use of Distillation Clause in Contracts

Distillation. The heavy duty gas turbine is not sensitive to the distillation characteristics of the fuel per se. Extremely volatile fuels such as naphthas require the use of a start-up fuel (light distillate) due to the low temperature at which they vaporize, giving the possibility of combustible vapors in the fuel lines. Very high end-point fuels, approximately 1000(Degree)F (538(Degree)C), can have excessive traces of vanadium which have distilled over. For this reason pure distillate usually would have a maximum end point specification. (This is also prevented by setting a maximum vanadium level.)
