KHU™ modular upgrader · For producers, refiners and EPCs

Upgrade heavy crude where it’s produced.

Kalvera’s patented KHU™ process upgrades extra-heavy crude at the field, in modular units built and tested in the United States. The upgraded barrel can replace imported diluent, so producers move more crude with less diluent, simpler logistics and better project economics.

Problem

Heavy crude can need up to ~40% diluent just to reach a pipeline.

Solution

KHU™ upgrades it at the field, and the upgraded barrel can become the diluent.

Opportunity

Modular units bring upgrading to stranded heavy barrels and refinery residue, train by train.

02The heavy-oil challengeDetail B · Feedstock

An enormous resource, held back by its own weight.

Extra-heavy crude is one of the world’s largest energy resources. But at ambient temperature it barely flows.

To move it by pipeline, producers blend in lighter hydrocarbons, called diluents. In some applications diluent approaches 40% of the transported blend, and every barrel of it has to be bought, delivered and moved.

General notes
  1. Viscosity

    Hard to produce, hard to move. Extra-heavy crude resists flow at ambient temperatures.

  2. Diluent dependence

    Diluent is often imported, and it can be costly, unreliable or hard to secure in sufficient volume.

  3. Centralized capital

    Conventional upgrading, such as delayed coking, means large, capital-intensive facilities far from remote fields.

03Our technologyDetail C · Ref. Fig. 1–2

A different approach to upgrading.

Specialized catalysts and a purpose-built reactor convert extra-heavy crude into lighter, more marketable streams. The upgraded product can serve as the blending component itself, reducing or even eliminating externally sourced diluent.

05Two marketsDetail E

One process, two markets.

For producers

Extra-heavy crude upgrading

Upgrade at or near the field to cut diluent requirements, improve transportation economics and make marginal production attractive.

Heavy Crude
For refiners

Refinery residual processing

Turn selected residual streams into higher-value products such as base-oil precursors.
