FCC gasoline selective hydro-desulfurization
High-pressure reactors and high-pressure heat exchangers can be designed independently and quickly according to the requirements of plant;
Technologies of naphtha and diesel hydrofining
The process is advanced, reliable, economical, reasonable, lower consumption shorter construction period. The scheme of mixing hydrogen in advance can improve heat exchanger efficiency and mitigate coking degree.
Technologies of FCC diesel oil hydro-upgrading
Typical process is advanced, reliable, economical, reasonable and low consumption, and has low pressure stream as a by-product. The reacting section adopts hot high pressure separator process to save energy and the area of exchanger. The internal components of reactor are optimized to reduce the temperature difference in bed layer radial. Plant is highly automated, easily operated.
Technologies of wax oil hydro-desulfurization
The process is advanced, reliable, economical, reasonable, lower consumption shorter construction period. The scheme of mixing hydrogen in advance can improve heat exchanger efficiency and mitigate coking degree. The internal components of reactor are optimized to reduce the temperature difference in bed layer radial. Plant is highly automated, easily operated.
Technologies of lubricating oil hydrogenation
The process is advanced, reliable, economical, reasonable, lower consumption shorter construction period. The scheme of mixing hydrogen in advance can improve heat exchanger efficiency and mitigate coking degree. The internal components of reactor are optimized to reduce the temperature difference in bed layer radial. Plant is highly automated, easily operated.
Technologies of residual oil hydro-desulfurization
Double series are set in reaction section. Every series can be operated alone. The reactor is single bed and bed distributor has good performance. The hydraulic recovery turbine is set between hot high pressure separator and hot low pressure separator. Fractionation section uses single fractionating column.
Technologies of wax oil hydrocracking
The reaction section uses one segment tandem technology, combining operation of tail oil full cycle maximum increase yield diesel scheme and tail oil lateral whip as lubricating oil hydrogenation. The device runs flexibly and heat exchange process is optimized and the overall energy consumption is less.
Technologies of solvent oil hydrogenation
The reaction section uses one segment tandem technology and deeply de-aromatic technology to produce low aromatic environmental solvent oil. Fractionation section use steam stripping and twin towers narrow fractionation process, reduces investment, energy consumption and layout compared with other fractionation scheme under the precondition of meeting fractionation precision.
