FEATURED PROJECTS

DexPro™ provided a compact dehydration skid, engineering, procurement and start-up assistance for the installation of a DexPro™ dehydration unit at Kinder Morgan’s Doe Canyon facility near Cortez, Colorado.

CUSTOM MADE INNOVATION

We customized the dehydration unit for Kinder Morgan’s exact needs with the following design specifications:

• Compact design to fit dehydration skid into existing building
• 30 MMSCF/d Inlet Design Capacity

COLLABORATIVE SOLUTION

DexPro™ worked with Kinder Morgan’s engineering and operation team to provide a customized package to address the capacity maximization challenges the client was facing. The end result was a design that added value with an optimal footprint, and increased production. Operators were trained on-site to run the system.

ALTERNATIVE SOLUTION

In a report about the DexPro™  installation, the Client’s consultant said DexPro™ “should be considered as an alternative to glycol dehydration in future Kinder Morgan CO₂ developments.” We are proud of this recommendation from one of the premier oil and gas companies in the world.

DexPro’s dehydration unit helped Tabula Rasa Energy implement CO2 injection into an existing waterflood scheme in the East Seminole Field. CO2 is delivered to the East Seminole Field via pipeline and is injected into selected zones for enhanced oil recovery. CO2 recovered from the oil production is dried with the DexPro™ dehydration unit and re-injected. Recovered hydrocarbons are sent to the inlet separator for recovery with the oil.

DexPro™ provided a dehydration unit, engineering, procurement, and construction support for Tabula Rasa’s East Seminole Field in Gain County, Texas.

LONG LASTING RELIABILITY

Tabula Rasa has used the dehydration unit without incident since 2015. Operators have little to no maintenance requirements to keep the DexPro™ skid in operation.

The DexPro™ dehydration unit has the following specifications:

• 30 MMSCF/d Inlet Design Capacity
• Design Conditions: 645 psig @ 150°F (66°C) Main Process
• High Pressure Recycle System 2150 psig @ 150°F (66°C)
• Hydrocarbon Liquid Recovery as Sales Oil

EASY EXPANSION

DexPro’s dehydration unit was designed for the full capacity of 5 injection compressors and installed with the first 2 injection compressors.  As gas production increased, the third compressor was installed without requiring any adjustments to the DexPro™ Dehydration unit.

EXACTING DETAIL

DexPro™ worked with Tabula Rasa’s engineering team to design and deliver a customized dehydration solution to fit their exact specifications required at site for dehydration.

DexPro™ provided a dehydration unit, engineering, procurement, construction support, and start-up assistance at Occidental Petroleum Corporation’s North Hobbs facility located in Hobbs, New Mexico, USA. Occidental chose the DexPro™ dehydration solution to expand the EOR Re-Injection Compression Facility’s solution gas handling with the added benefit of recovering hydrocarbon liquids from the EOR CO2 stream.

CUSTOMIZED SOLUTIONS

DexPro™ provided Occidental with a custom designed solution to their dehydration needs. The unit was designed for 135 MMSCF/d Inlet Design Capacity with a compact modular design to reduce shipping costs.

EXPANDED CAPACITY

In order to expand EOR solution gas handling capacity, DexPro™ provided an enhanced dehydration process, which has the additional capability of recovering heavier hydrocarbon components present in the EOR recycle streams. This creates a revenue stream, whereas a typical glycol dehydration system only generates an expense.

Occidental chose the DexPro™ dehydration solution to expand the EOR Re-Injection Compression Facility’s solution gas handling with the added benefit of recovering hydrocarbon liquids from the EOR CO2 stream.

CUSTOMIZED DEHYDRATION SOLUTION FOR EOR

DexPro™ provided Occidental with a custom designed solution to their dehydration needs. The unit was designed for 120 MMSCF/d Inlet Design Capacity with a compact modular design to reduce shipping costs.

DexPro™ provided engineering, procurement, construction support, and start-up assistance for the installation of six DexPro™ dehydration units at Chevron’s Gorgon Facility on Barrow Island, Western Australia.

During preparations for the initial injection pipeline start-up, it was determined that there were vulnerabilities within the CO₂ system to off-design conditions which posed a risk of water condensation with associated rapid corrosion risk within the CO₂ injection system’s carbon steel pipeline and piping.

To enable start-up of the CO₂ injection system with minimal deviation from the intended start-up dates and to avoid risking the integrity of the carbon steel system, it was determined that it was necessary to reduce the water dewpoint of the CO₂ being fed forward from the Gorgon facility compression system. The DexPro™ process was applied to remediate the high water content issue.

REDUCING ENVIRONMENTAL IMPACT

Maintaining the environmental integrity of the area was of the utmost importance because Barrow Island is a designated A-class nature reserve for the purpose of conservation of flora and fauna. The marine environment around Barrow Island is also part of the Montebello-Barrow Island marine conservation reserves, which comprises a wide variety of habitats and extremely high marine biodiversity.

The Gorgon facility processes 2.6 BCF/d and 200,000 bbl/d of condensate and is configured with three processing trains. Each train has a dedicated Acid Gas Removal Unit (ARGU), with a dedicated CO2 Injection Unit comprising two 50% CO2 Injection Compressors. The acid gas discharge from the CO2 compression trains is co-mingled and routed via a common header along the main pipe rack to the 4.35 mile (7 km) CO2 pipeline to multiple injection wells at three drill centres.

The DexPro™ dehydration units — with each of the six units capable of 46 MMSCF/d Inlet Design Capacity — allowed the facility to transition from venting CO2 to injecting CO2.

ENVIRONMENTAL RESPONSIBILITY

With the focus on environmental protection, DexPro’s dehydration system was a good fit, as it has almost no emissions or waste products that are associated with other dehydration systems.

STARTUP ASSISTANCE

DexPro™ worked with Chevron’s design team to incorporate the DexPro™  dehydration units into the existing facility and the operations team to start-up and control the equipment.
