(Plastemart) -- South Korea's SK
Energy has begun test runs on a steam cracker at its Ulsan complex that utilizes
experimental technology, as per Platts. The cracker uses naphtha as the primary
raw material, but is also able to use diesel or kerosene as secondary
feedstocks.
Besides a wider choice in feedstocks, a special feature of the process is
the high ratio of propylene yield compared with ethylene, about 1:1.
Mechanical completion of the cracker, which is able to produce 20,000 tpa
each of ethylene and propylene, was completed in August and feedstock was first
fed into the unit on October 25.
The cracker will be operational for a year before a decision is made on
further investment on a commercial-scale plant using the same technology.
