Odorize Gas - GPL Odorizers 10000 Odorant Injection System

GPL 10000

The GPL 10000 odorizer is an eco-friendly odorant injection system used to odorize gas. The odorizer meets the demands of nearly all pipeline applications and ideal for high-volume and high-pressure applications. The 10000 is ideal for high-volume and high-pressure applications. With a 100:1 turndown ratio, the system injects precise quantities (0.2% accuracy) of liquid odorant across the entire operating range, in both continuous and batch modes.

About GPL Odorizers

GPL Odorizers (formerly Sentry Equipment and Zeck Systems) manufactures environmentally-friendly odorant injection systems for natural gas and other gases.

Odorize Gas Differently

The GPL 10000 is electrically driven and hydraulically isolated. Pipeline gas does not actuate the injector, meaning our odorizers do not vent gas to the atmosphere, making this system environmentally friendly. Additionally, since GPL odorizers are self-contained and do not discharge gas, there is improved safety, pipeline gas is saved, and subsequently, odor at the unit is reduced. As a result, there is a reduction in leak call complaints.

The GPL Odorizers also have fewer moving parts than the leading competitive odorization systems, meaning less maintenance over the unit’s life.

Features & Benefits

What makes GPL 10000 Unique?

odorant injection system enclosureWhat makes the GPL 10000 unique is its dual stroke electrohydraulic pump. A variable speed electric servo motor drives a stochastic mechanism that converts the motor's rotary motion into linear double stroke motion. This provides the force to drive two independent metal Bellows Pump modules. The dual stroke sends the hydraulic fluid into one of the pump modules, compressing the bellows to discharge a fixed volume of the odorant. Simultaneously, hydraulic fluid is withdrawn from the opposite pump module, expanding that bellows and drawing in new odorant for the next injection stroke. This action provides nearly continuous injection flow, a feature not offered by single pump injectors. As the pipeline flow rate varies, the pump motor speed is adjusted to change the time per stroke while maintaining a continuous flow of odorant in the process. Since the motor has the maximum rate of 25 revolutions per minute, fluid flashing, due to acceleration induced pressure drop, is virtually eliminated. Additionally, the Bellows Pump's hydraulic section is completely isolated from the odorant section, and there are no seals or diaphragms to replace in the odorant section of the pumping circuit. The only replacement items are the hydraulic piston seals that have been engineered for high cycle life. When piston seal replacement is required, the drive system is easily isolated from the pump modules by closing the isolation ball valve located on each hydraulic line. The piston seals are captured within cartridge assemblies to allow for quick and easy replacement. The GPL 10000 odorizer uses the state of the art technology for accurate, repeatable, and low maintenance odorant injection.
