Coking presents problems for Neste Oil's diesel line

Neste Oil restarted the new diesel line (PL4) at its Porvoo refinery
as planned during the last week of May, following the completion of
repair work after a fire at the beginning of April. A coking problem
has been observed on the line, however, which requires throughput to
be reduced temporarily and the line to be fed with
lighter-than-planned feedstock.
