English term or phrase: Reactor bed blinding
By removing catalyst fines from slurry oil, or main column bottoms, product fuel oils can be upgraded, or feedstock can be provided for production of carbon black or other products.
The installed particulate filter elements (typically 5 to 20 micron mesh stainless steel) will address the fouling caused by catalyst particles from the reactor.
The operating conditions dictate the type, number, selectivity and cleaning mechanism/process of the filter elements.
The solid (particle) characteristics and quantity may result in several filtration and cleaning challenges.
Feed Filter
The feed filter is a process critical particulate filter, typically located between the process unit feed pumps and the first stage heat exchangers to address the fouling and reactor plugging problems.
The capacity and type of hydrocarbon dictate the type of filter element, the selectivity and cleaning mechanism.
» Typical feedstocks are residual oil, gas oil, de-asphalted oil, middle distillate (VGO, HVGO, HGO, LGO etc.) and naphtha.
» Particle filtration upgrades the feedstocks for further processing elsewhere in the plant.
» Typically 20 to 80 micron wedge wire or mesh stainless steel filter elements are installed.
Operational problems
» Heat exchanger fouling
» Reactor bed blinding
» Hydrogen contamination
» Final product contamination
These operational problems degrade hydrocracking or hydrotreating performance and can lead to off-spec product, premature unit shutdown and significant increased operating cost for the process unit.

Защита, с помощью которой ваш реактор будет работать без перебоев

Засорение слоя катализатора может быть вызвано рядом факторов.

Адаптация необходима при обнаружении таких возмущений, как проскок каталитических ядов, перегрев и спекание катализаторов в реакторах, изменение условий теплообмена в теплоиспользующей аппаратуре.

Подобно железу, соли натрия вызывают засорение слоя катализатора и закупорку пор.
