We at Joule Processing pride ourselves on being at the forefront of process technologies, whose strengths include extensive process engineering capabilities with an intricate understanding of the relationship between processing metrics, producer interests and midstream solutions.

Our value proposition is the ability to combine these strengths with the ability to package high-performance technologies in a cost-effective manner with a speed-to-market approach. We review each application with its own merit and determine the best solution based on the parameters provided. We also look at each application as having variable conditions instead of a static analysis, leading us to the optimal solution.

In an effort to deepen the suite of technologies, Joule has strategically teamed with Fluor to offer premium solutions for the unconventional natural gas and liquid handling market.

Fluor

Fluor is a technology leader in the natural gas industry specializing in gas processing, gas treating, NGL recovery, nitrogen rejection, product fractionation, LNG, sulfur recovery, power generation, carbon capture and other technologies. After many years and just before the current market downturn, Fluor decided to re-enter the U.S. midstream market. Fluor has several patented and proven design innovations which yield high performance and operational flexibility at a lower cost than competing technologies, thereby answering the current demands of the midstream market.

Fluor’s Cryo-Gas℠ Patented Technologies

Fluor and Joule have worked hand-in-hand to productize and package Fluor’s Cryo-Gas℠ patented technologies, the industry’s most cost-competitive solutions for rich gas applications. Fluor and Joule are proud to offer the following technologies:

Deep Dewpointing Process (DDP)

  • DDP is a process module designed for rich, unconventional gas applications, with gas liquid contents from 6 to 12 GPM and feed pressure ranging from 500 psig to 950 psig. The process can recover up to 98% propane while fully rejecting ethane (as low as 1% ethane in NGL product).
  • The DDP standard design does not require the use of a turboexpander. The absence of turboexpander allows the process to operate at high turndown (4:1), while maintaining high recoveries over a wide range of inlet gas compositions.
  • The DDP can process heavier gases without encountering thermal stress problems common in brazed aluminum exchangers.
  • DDP has a lower pressure drop across the system compared to turboexpander technologies. The design lowers the residue HP requirements but increases refrigeration HP, which is electric. This difference gives the operator increased processing capacity and lower emissions regarding permits.
  • The refrigerant utilized in DDP process is propane, not a mixed refrigerant.
  • DDP has a modular, skid-mounted design for simple installation and mobility purposes.

The Fluor DDP can be operated in moderate ethane recovery, recovering 40 to 70% of ethane while maintaining high propane recovery, without additional equipment.

However, when high ethane recovery is required, Joule and Fluor can offer an integrated solution or one of the following true bolt-on solutions:

Enhanced Residue Gas Recycle (ERGR)

  • ERGR can recover up to 99% propane and over 95% ethane and installed for in a green or brown field application for richer gas.
  • The ERGR can be bolted on to the downstream side of a GSP or other turboexpander plants. When it is installed after a DDP operating in full ethane rejection, the ERGR produces a pure ethane product ready for delivery to on-spec markets.

Twin Reflux Absorption Process (TRAP)

  • TRAP is designed for high pressure, leaner gas with 2 to 5 GPM liquid content. Using turbo expansion to generate cooling and reduce power consumption, TRAP can recover up to 95% ethane and 99% propane.
  • TRAP is ideal for revamping existing, underperforming NGL plants for ethane recovery.

DDP-TRAP

  • With the addition of an expander, the ethane recovery of the DDP can be increased and converted to the TRAP process. The combination process can be installed in two phases, with the initial DDP phase operating in ethane rejection or partial rejection and the final TRAP phase recovering over 95% ethane while maintaining 99% propane recovery.
  • The turbo-expander can be installed at a later date when ethane demand increases.
