C1 heavy fuel oil

The C1 heavy heating oil is obtained from vacuum residues, discoloured products, vacuum fractions from DRW (fractional distillation) and HOG (hydrodesulphurisation) processes, clarified oil from FKK (catalytic cracking installation), phurphurol extract, waste liquid distillation residues, post-pyrolysis oil, phenol and cumene tar. To achieve the required viscosity of the liquid, fractions of fuel oil from the processes are used as a thinner.

The product sulphur content is limited to 1%, by weight.
Heavy heating oil '1' is used as a fuel for firing central heating boilers, steam boilers, industrial furnaces and for technological purposes.
