Gas-to-Liquids Solution

  STG+ Product Brochure.pdf

Jereh Group, an international, integrated oil and gas company specializing in Oil and Gas EPC services, oilfield technology services and equipment manufacturing, and Primus Green Energy, a gas-to-liquids (GTL) technology and solutions company that transforms natural gas and other hydrocarbon gases into gasoline, methanol and diluent, teamed up to jointly deploy a range of flexible, robust and modular GTL systems to our global customers for gas monetization.

What Are The Challenges For Gas Utilization?
1. Associated gas flaring, waste of valuable resources and a critical threat to the environment
2. Stranded gas at wellsite due to the lack of pipeline infrastructure
3. Syngas from underutilized reformer or gasifier
The Jereh-Primus team offers a range of flexible and robust GTL systems to meet the increased demand for gas monetization. Our advanced solutions are available on a single-vendor EPC basis for all scales.

The Jereh-Primus GTL solution is unmatched in the industry for simplicity and profitability thanks to its:
  • Flexible feed gas requirements
  • Proven GTL technology
  • Modular design and fabrication
  • Standard package for quick delivery
  • Global sales, execution, and post-project support
  • Integrated EPC solution

How The STG+™ Gasoline Process Works
The Primus Gas-to-Liquids process takes place in a continuous gas-phase closed loop, with no intermediate condensation steps.

    Gas-to-Gasoline Process
  • Steam Methane Reforming - Natural gas or other hydrocarbon gas reacts with steam at a high temperature and pressure to produce syngas (CO and H2).
  • Syngas-to-Gasoline - A series of catalytic fixed-bed reactors convert the syngas into gasoline and water via methanol and dimethyl-ether intermediates.
  • Liquid/Gas Separation - The products are cooled and condensed. The gasoline product is sent to storage; the water is reused to make steam for the reformer; and the unconverted gas is recycled, with a portion being used to fuel the system.

  • Gas-to-Methanol Process
  • Steam Methane Reforming – Natural or other hydrocarbon gas reacts with steam at a high temperature and pressure to produce syngas (CO and H2).
  • Syngas to Methanol Reaction – Syngas reacts in a catalytic fixed bed reactor that converts the syngas to methanol.
  • Distillation/ Separation – The water/methanol mixture is separated from other gases, and then fed to a distillation column system that is designed to meet the user’s methanol purity requirements. On-spec methanol is collected from the top of the column, water is reused to make steam for the reformer and off-gas is recycled as feed or fuel to the reformer.

Best In Class GTL Solution
Compared to other GTL technologies, our STG+™ solution has the following advantages:
  • Low cost modular design
  • Cost effective at gas flows as small as 4 MMSCFD (100,000 Nm3/d)
  • Single finished product stream
  • 100% standard components
  • Long catalyst lifetime
  • Accepts CO2 in feed gas, up to 25%
  • Accepts variety of feed gas types (wellhead, pipeline, wet, dry,…)
  • Incorporates syngas directly from steam methane reformer, no shift reactor is needed
  • No gas pretreatment needed
  • No product post-treatment needed
  • No wastewater or other waste streams
  • No intermediate condensation steps - Entire process takes place in a gas-phase continuous loop
