GEM has been performing high-quality, professional vapor, odor, and emissions control since 1994.
Our staff is trained and experienced in applying cutting-edge treatment technologies to ensure our clients’ emissions challenges are met while we focus on safety and compliance. Whether it’s vapor combustion, liquid vapor scrubbing or carbon absorption, GEM has the appropriate solution.
Tank & Pipeline Degassing
GEM offers mobile vapor control and degassing through a variety of proven technologies. Our staff prioritizes safety, compliance, and meeting our clients’ emissions challenges. GEM’s diverse fleet of equipment ensures that we can meet each customer’s unique project needs.
GEM’s Mobile Vapor Combustion Units range in size from 1.5 MM BTU to 42 MM BTU and can handle various vapor flow rates up to 3,000 SCFM. By offering the broadest range of vapor combustor sizes, GEM has the ability to handle low-flow passive vapor control needs or specialty high-flow vapor destruction, typical for large product or crude tanks.
Vapor Scrubbing & Odor Control
Similarly, GEM’s combination of carbon with liquid scrubbing is often the most cost-effective approach for controlling vapors generated by sludge processing operations, barges, tankers, and API separators.
GEM provides liquid scrubbing solutions to enhance carbon vapor control systems. GEM utilizes specialized chemistry to control VOCs, proprietary caustic solution to scrub H2S, and acid to remove ammonia from vapor streams. Our in-house equipment has flow capacity of up to 500 SCFM. We offer single vessel, combination vessel, and a number of specialty packed scrubbers.
Loading Rack Vapor Control
GEM’s high-capacity vapor combustion equipment is ideal as a substitute vapor control system when service is needed at a gasoline or product terminal loading rack. Our extensive experience with petroleum terminals has positioned GEM as the go-to service provider in emergency situations where customers can’t afford to slow product flow. By owning and operating the largest fleet of mobile vapor combustors available, GEM has the capacity to control small to high vapor flow applications.
Marine Vapor Control Services
GEM has applied our extensive experience in vapor combustion to controlling the vapor emissions from product or crude oil marine loading activity. With the high-flow capacity of our thermal units, our marine loading clients are able to obtain the necessary flow rates needed to meet the shipment demands of their customers. In combination with a GEM Dock Safety Skid (DSS), our systems are Coast Guard Compliant per 33 CFR 154 Subpart E and provided with a facility CE certification. GEM Marine Vapor Control Systems have served customers on all coasts, as well as on the major inland waterways throughout the U.S., and we are experienced working with the U.S. Coast Guard to help obtain the necessary permits required for safe loading operations.
Because we recognize the importance of equipment reliability, we prioritize preventive and scheduled maintenance and will dispatch our technical personnel from any of our service locations at a moment’s notice to minimize downtime
Barge & Ship Degassing
Our vapor combustion equipment is used for the degassing of barges or ships that transport volatile products throughout our inland waterway systems or over oceans. We routinely clear vapors from compartments after product stripping, prior to entry for safe cleaning, or for safe transport to loading destination. Our vapor control systems comply with applicable U.S. Coast Guard regulations.
Turnaround and MSS Support Services
We integrate the details of large, complex shutdowns that must be completed safely, on schedule, and on budget. Our proven success record includes numerous refinery-wide shutdowns throughout the U.S. Specific project management methodologies reduce variation and increase efficiencies. We continually measure and analyze our customers’ KPIs for process improvement. Our thermal technologies enable refinery or chemical plants to clear tanks, units, or vessels in a fraction of the time it typically would take using traditional methodologies. Our specialty vapor control equipment can meet Class 1 Division Il requirements, allowing us to perform work in the most sensitive areas of our customers’ plants.
In addition, GEM has developed a wide variety of vapor control solutions to assist customers with Maintenance Startup & Shutdown (MSS) permit compliance. Our comprehensive emission management program offers multiple customized options to meet individual facility needs. Evergreen’s equipment is designed to control vapors from a variety of sources, including tanks, vessels, pipelines, vacuum trucks & air movers, sumps, frac tanks, and process units. GEM’s Vapor Control Systems are designed to meet all TCEQ/BACT requirements.
