According
to TPC, at the PBL section of the ABS unit of the facility, after the reaction,
the unreacted monomers of butadiene are recovered. Based on the unit’s design,
the recovered monomers are transferred to the TK-403 tank which can cause
explosion and environmental hazards.
Considering
the necessity of identifying and managing the costs associated with the waste
of valuable products of the company and minimizing flaring as one of the
environmental projects of TPC, a project aimed at reusing the recovered
monomers of butadiene has been defined and reviewing the processes at the olefin
and BD units was put on the company’s agenda.
By completion
of the project, the recovered butadiene is sent to the TK-804 reservoir as
feedstock for the BD unit. This could be translated into production of roughly 1000kg
of butadiene per day.
