TRIPOLYTA is holding talks with Mitsui & Co for its propane dehydrogenation unit, and with Toman and Tonen Corp for a 120 000 tonne/year n-butanol project.
The Indonesian company said talks with Mitsui & Co are preliminary, but it expects to be a major shareholder in the propane dehydrogenation project. However, the project will not proceed if a long-term propane supply is not secured. Instead it may consider taking part in an olefins facility.
The feasibility study for the 350-500 000 tonne/year facility will be completed by end-March. ABB Lummus and UOP technologies are being considered.
The project would require propane feedstock of 430-615 000 tonne/year. TriPolyta thinks that for the US$250-300m unit to be economically feasible, there must be an economic differential of US$200-250/tonne between propylene and propane stock prices.
TriPolyta believes commercial production can be ready in time to replace the reduction in minimum purchases of propylene under the current propylene supply agreement with Chandra Asri.
The butanol project involves relocating Tonen's existing plant from Kawasaki, Japan, to TriPolyta's site in Cilegon, West Java, as well as the addition of a second reactor. The feasibility study of the US$82m project is expected to be ready in Q2 or Q3 this year.
Tonen's existing butanol plant produces 59 500 tonne/year of n-butanol and 4400 tonne/year of isobutanol. The second reactor will lift capacity to 120 000 tonne/year of n-butanol and 9000 tonne/year of isobutanol. The project will require 83 000 tonne/year of propylene feedstock.
The butanol plant will feed the acrylic esters plant of TriPolyta's joint-venture, Nisshoku TriPolyta Acrylindo (see box).
