Residue Hydroconversion & Hydroprocessing

Hyvahl™

Hyvahl™ is a high-performance RDS process with a perfect commercial operation safety record. It has been employed both for improving residue quality for use as an FCC feed and for the production of Ultra Low Sulfur Fuel Oil (ULSFO) addressing thus IMO 2020 targets.

The residue and hydrogen are pre-heated and then fed into the reactor section. Upgrading begins with a Permutable guard-bed Reactor System (PRS) to eliminate undesirable metals through hydrodemetallization (HDM), followed by a transition section and the final hydrotreating section for HydroDeSulfurization (HDS), HydroDeNitrogenation (HDN) and CCR reduction through HyDrotreating (HDCCR).

Hyvahl™ technology features:

• Can process AR/VR blends or 100% VR with high metals content
• Attains the most stringent ULSFO specifications with sulfur content as low as 0.28 wt. % (Middle East crude) throughout long cycle lengths
• Typical conversions range from 15 to 25 wt. %
• Produces low sulfur diesel
• Produces an excellent RFCC feed

Furnaces

Furnace(s) is a key equipment considering the need for optimal operation of unit. Thanks to an extensive design experience with feedbacks from operators and a complete knowledge of this process, Heurtey Petrochem Solutions provides an unparalleled service such as these following features:

• High fuel efficiency (94%+) depending on fuel S level
• Fully Modularized
• Lowest Emission (95%+ reduction with emission reduction technology)
• Optimized Plot Plan

H-Oil®

Axens is the leader in the ebullated-bed market with more than 25 references all around the world.

With its extensive operating experience, H-Oil® is the most mature and reliable solution for residue upgrading. H-Oil® meets the challenge of converting heavy feedstock residues into essentially distillate products, ranging from vacuum gasoil (VGO) to naphtha. Such performances are achieved in the original ebullated-bed H-Oil® reactor, possibly in combination with other units.

The process utilizes an ebullated bed reactor with daily catalyst addition and withdrawal to not only achieve high desulfurization rates but also a wide conversion envelope, VR conversion ranges from 70 to 95wt%. Thanks to daily addition, no shutdown for catalyst replacement occurs. The H-Oil® unit has a stream factor superior than 96%. One of the main technology features is its flexibility both in terms of feedstock and product slate; commercial units have demonstrated significant flexibility in their conversion targets while processing a wide range of residual feed streams from paraffinic Russian Urals to heavy Canadian bitumen. PyOil from crude to Petrochemical scheme is nowadays co-process in the H-Oil® unit.

H-Oil® Suite

Relying on the proven reliability of the H-Oil® technology platform, the H-Oil® Suite aims at integrating the upgrading of residue in the refinery’s environment at best, while saving energy and optimizing the use of existing facilities.

In H-Oil®+, the “+” stands for an “additional feature” that works with the basic H-Oil® process technology. Several options are available to meet the refiners need for valuable additional conversion points while keeping costs to a reasonable level.

Those advanced options include:

• Low space velocity to achieve 90+% conversion while maintaining product stability
• Adding HCAT liquid catalyst precursor to the solid catalyst system to further increase the conversion envelope by increasing catalytic hydrogen transfer, available catalytic reactor volume, and therefore dramatically increasing product stability. HCAT liquid catalyst is supplied by HTI.
• Integrating H-Oil® in a residue conversion block including with SDA,Coker or Flexicoking units, reducing the production of and increasing the value of the rejected carbon molecules.
