The propylene oxide production unit

​

Project power: 2 700 t/y of propylene oxide

Customer: KARPATNAFTOCHIM LTD

Technology developer: LLC "Manufactiuring Group" Techinservice "

Сhief designer: LLC "Manufacturing Group"Techinservice"

General contractor: PJSC «Grebinki a Machine-Building Factory»

Implementation period: November 2018 - March 2019

 

Description of the project:

​

The project is based on the technology of the LLC "Production Group" Techinservice " which developed in 2017  its own process of production propylene oxide from propylene and hydrogen peroxide by epoxidation using a TS-1 catalyst of its own production.  This technology, called HPPOa differs from existing world analogues by using a catalyst the production process of which is differe by use of solid fumed silica as a source of silicon ions and using acetonitrile as a propylene solvent.  The technology of HPPOa has successfully passed the laboratory stage and is at the stage of industrial implementation.  Techinservice  has begun designing a unit with a capacity of 2 700 tons per year, and also began to develop and manufacture the equipment of this project.  The installation is scheduled on March 2018.

The deoxygenating hydrogenation block

 

Customer: KARPATNAFTOCHIM LTD

Technology developer: LLC "Manufacturing Group" Techinservice "

Project documentation development contractor: LLC "Manufacturing Group" Techinservice "

Implementation period: April - September 2018

​

Description of the project:

​

The project contemplatesthe installation of hydrogen deoxygenation block on the existing line of hydrogen produced by chlorine and caustic soda by the membrane method (CACS MM)  KARPATNAFTOCHIM LTD.  The block is intended for removal of an admixture of oxygen contained in water which was received at the installation of CACS MM catalything  in the reactor.  As a catalyst in the project it was used the spherical palladium catalyst on the gamma-alumina carrier from ANCO CATALYST LTD .  The unit's productivity is estimated at 400 kg / h of hydrogen.  The residual oxygen content after purging in the unit of antioxidation does not exceed 5 ppm.

​

The project was successfully implemented and fully digitalized and put into operation in September 2018.
