AI Technical Summary

Technical Problem

Solid particles in heavy oil hydrotreating reactors can clog the catalyst bed, leading to reduced reaction efficiency, frequent shutdowns for cleaning, and disruption to normal operation.

Method used

A fouling device, including a liquid storage pan and a fouling distributor, is installed in the hydrogenation reactor to prolong the time for the liquid phase to enter the catalyst bed, allowing solid particles to settle. Through the deflection and dispersion structure of the gas-liquid mixture, a multi-stage deposition zone is formed, reducing the amount of solid particles entering the catalyst bed.

Benefits of technology

It effectively reduces the frequency of reactor shutdown and cleaning, extends the cleaning time by more than 65%, reduces the impact of gas-liquid mixing flow on the internal structure of the reactor, and improves the diffusion range and mass transfer effect of heavy oil.

Abstract

一种重油加氢反应器用积垢装置及加氢反应器,属于化工设备领域,包括处于加氢反应器内入口扩散器和分配盘之间的蓄液盘,在蓄液盘上分布若干积垢分流器,每一个积垢分流器包括一根贯通蓄液盘的导液管,气液混合物进入导液管并冲击在下溅液机构上分散后汇聚到分配盘上;上折流板的上表面形成第一积垢区,分配盘上分布的气液分配机构顶部接近下溅液机构,以使气液分配机构的顶部形成第二积垢区;本发明能够延长液相进入催化剂床层的时间,从而使其中的固体颗粒物产生沉降,大幅度降低进入催化剂床层的固体颗粒物,有效降低了反应器的停机清理频率,经过实验验证,在同等工况下,能够延长反应器清理时间65%以上。
