Reconstruction of the desulphurisation equipment in Unipetrol
Client: UNIPETROL RPA, s.r.o.
Project duration: 30 months
Reconstruction and modification of the existing desulphurisation equipment of the K13 through K20 boilers on the premises of the refinery in Litvínov. The simultaneous desulphurisation method consisting in controlled injecting of dry powder sorbent into the existing semi-dry desulphurization absorber was selected. It reduces SO2 emissions below 130 mg/Nm3, which is an emission limit in force from 2020. The project also included the construction of a new reagent storage silo having the capacity of 800 m3, installation of two compressors and two independent lines for the controlled reagent injection, replacement of circuit breakers, and extension of the existing control system.
