SIBUR to build methanol separating unit in Russia
Low methanol content is a requirement of many consumers. The new unit will be the next step in SIBUR’s ongoing goal to lower the content of methanol in the propane fraction, this time in a range not exceeding 50 parts per million, according to the company. Financial terms were not disclosed.
SIBUR has started the construction of unit for separating
methanol from propane fraction at Tobolsk-Neftekhim, the
Russian-based petrochemicals group said on
Low methanol content is a requirement of many consumers. The
new unit will be the next step in SIBURs ongoing goal to
lower the content of methanol in the propane fraction, this
time in a range not exceeding 50 parts per million, according
to the company.
At the beginning of 2011, Tobolsk-Neftekhim launched a new
purification unit lowering methanol content to a level of less
than 0.1%. In January 2012 another project was completed,
lowering methanol content to a summer
percentage of 0.015% and winter percentage of 0.035%.
The new propane gas purification unit will have a projected
capacity of up to 2.1 million tpy. The project documentation was developed
by SIBURs engineering centre NIPIgazpererabotka.
The project is based on SIBURs
proprietary simultaneous propane stream separation and
dehydration technology. The environmental impact will be
minimized through a closed-cycle operation with excess methanol sent to a plant synthesising
MTBE fuel additive, while excess water will be recycled,
according to company officials.
The project documentation was approved
by the Government Expert Review Board (Glavgosexpertiza). The
construction site has been prepared
and orders for long-lead equipment have been placed.
The construction works have entered the
preparation stage and are scheduled for completion in 2014.
