The Primus STG+™ Gas-to-Gasoline System

The Growing Demand for Gas Monezaon Technologies

NaturalNatural gas producon is on the rise in the United States and around the world. How-ever, as unconvenonal drilling techniques unlock vast reserves of hydrocarbon re-sources, natural gas is oen stranded at the wellsite because producers are unable to get it to market due to the lack of pipeline infrastructure. This problem is parcularly acute for associated gas, which is a byproduct of oil producon. In remote locaons, oilfield operators oen have had no choice but to flare associated gas, which is a waste of valuable resources and a crical threat to the environment due to the release of greenhousegreenhouse gases. Regulators around the world are now implemenng increasingly stringent restricons to curb gas flaring. As a result, the demand for gas monezaon technology is growing. Producers of associated gas seek new soluons that offer a mely and cost-effecve means of compliance, and owners of stranded gas reserves seek to moneze their assets even when pipeline infrastructure is limited.

Primus’ Gas-to-Liquids SolutionSimple. Robust. Economical.

As a global leader in gas-to-liquids (GTL) solutions, Primus offers a range of flexible, advanced GTL systems to meet the increased demand for gas monetization technologies.technologies. Our robust STG+™ units produce high-quality gasoline or diluent directly from a wide range of hydrocarbon gas feedstocks. Unlike large stick-built units, our modular units are uniquely designed to be cost-effective at all scales, starting as small as 4 mmscf/day of feed gas. Primus’ STG+™ system is unmatched in the industry for simplicity and profitability thanks to its flexible feed gas requirements, modular design and single finished liquid product. PrimusPrimus STG+™ units have been optimized for a number of critical applications, includ-ing flared gas utilization, monetization of stranded ethane, conversion of pipeline gas into valuable liquids, and monetization of excess syngas from underutilized reformers. Primus is committed to continually developing new solutions and applications – as well as to advancing our existing systems – in order to meet our customers’ unique business needs.

Flexible Feed Gas Requirements

Primus’ technology can accommodate a wide range of feed gas types:

• Associated gas • Pipeline natural gas • Dry or wet gas, no limits for C2,, C3, C4 • Ethane or mixed NGLs • Ethane or mixed NGLs • CO2 up to approximately 25% • Syngas

Attractive Economics• Cost effective at scales as small as 500 bpd • One of the best conversion yields in the GTL market• Lower capital and operating costs compared with alternative GTL technologies• Affordable, long-lifetime catalysts•• Minimal labor requirement – single operator during normal plant operation, remote operation available

Examples of Primus STG+™ System Applications

How it works

The Primus STG+™ Gas-to-Gasoline process is comprised of three steps:

1. Steam Methane Reforming - Natural gas or other hydrocarbon gas reacts with steam at a high temperature and pressure to produce syngas (CO and H2).

2.2. Syngas-to-Gasoline - A series of catalytic fixed-bed reactors convert the syngas into gas- oline and water via methanol and dimethyl- ether intermediates.

3.3. 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.

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

“The beauty of turning gas into gasoline is that there’s already a hundred million vehicles in the United States that can use it.” Forbes

High Quality Gasoline Zero Sulfur. Zero Benzene. The gasoline produced through Primus’ process has a unique zero-sulfur and zero- benzene profile and can be blended with refinery gasoline, sold directly into the wholesale market, or mixed with crude oil for simplified logistics at the wellhead. Primus’ gasoline meets most specifications globally without the need for additional refining. In without the need for additional refining. In the United States, Primus’ gasoline exceeds the requirements for RBOB grade gasoline and complies with other national grade specifications. For applications related to heavy oil produc-tion, the Primus system can produce on- spec diluent, offering producers a local, vertically integrated source of diluent.
