Osaka Plant. Since then, TOYO has received orders for the basic design and EPC for OCT plants in Japan, South Korea, Indonesia and other countries in Asia. Integration of CDIsis technology with OCT process allows an economical and cost effective solution to enhance propylene production. Skeletal Isomerization Reaction C5s OCT Available C4s from steam cracker is being reduced due to the increasing demand of butadiene and the decreasing amount of liquid feed cracking. Based on these backgrounds, CDIsis technology was developed by Lummus to convert isobutene to normal butenes. CDIsis technology can maximize a utilization of isobutene in mixed C4 feedstock via OCT process. HOME Our Business Petrochemical OCT (Olefins Conversion Technology) Introduction. Olefin Conversion Technology (OCT) of Lummus is one of the on-purpose technologies, which has emerged as a low-capital and low-energy propylene production route.
It helps to lower the investment cost and reduce utility consumption in the OCT process. Because metathesis reaction is an energy neutral reaction, utility consumption is significantly reduced. The major utility requirement is limited to fuel gas for controlling reactor inlet temperature and steam and cooling water for distillation.
