Применение гидрокрекинга вакуумного остатка в кипящем слое на предприятии «ЛУКОЙЛ Нефтохим Бургас»

Abstract

This paper summarises the experience gained over seven years of operating the H-Oil hydrocracking technology with an ebullated vacuum residue bed. Four factors have been identified as major contributors to improved H-Oil performance: feedstock quality; catalyst condition; hydrocracking unconverted vacuum residue loading and utilisation. The optimum combination of all these factors made it possible to achieve a vacuum residue conversion rate of about 90%. It remains a challenge to find the correct use of the unconverted vacuum residue produced at higher conversion rates.
