Abstract: The present disclosure provides a system and method for odorizing natural gas flowing through a distribution pipeline. The system includes a bypass line adjacent to a distribution pipeline, wherein bypass gas flows through the bypass line and an odorant tank connected to the bypass line, and into the distribution pipeline; a high-flow control valve and a low-flow control valve in the bypass line, wherein bypass gas flows through the odorant tank into the distribution pipeline when the high-flow control valve or the low-flow control valve is open; and a programmable logic controller connected to the high-flow and low flow control valve; wherein the programmable logic controller opens the high-flow or low-flow control valve for a predetermined dwell time proportional to an amount of bypass gas needed to odorize gas in the distribution pipeline each time that a preselected quantity of gas flows through the distribution pipeline.

Abstract: When odorant injection systems are inactive, they may accumulate unwanted vapors in the pump mechanism and associated tubing. In order to restart the odorant injection system, it is best to purge the unwanted vapors from the odorant pumps. The present pump purge system facilitates purging of unwanted vapors from odorant injection systems in an environmentally friendly fashion. The pump purge system purifies these vapors before they are vented to atmosphere. In addition, the pump purge system accumulates liquid odorant which is a byproduct of the purging process and stores it in a tank to reduce the likelihood of improper disposal. As an option, the pump purge system may also include a liquid odorant recapture system. The liquid odorant recapture system uses high pressure gas to return accumulated liquid odorant to the odorant injection system to be reused. This liquid odorant recovery system ensures environmentally responsible behavior.

Abstract: A combination backpack and granular material dispenser that includes an upper compartment, a lower compartment extending downwardly from the upper compartment, at least one carrying strap, a valve assembly, and a valve assembly actuator. In use, the present invention enables a user to stow equipment and personal items in the upper compartment while stowing and dispensing a granular material from the lower compartment. The lower compartment is collapsible into and expansible from the upper compartment.

Abstract: The apparatus and method for venting and depressurization of an odorant injection system may be used on special LNG tankers that have onboard gasification equipment, on land or elsewhere. Odorant injection systems may operate at high pressures on an intermittent basis. On some occasions, the odorant is drained from a pressurized system and disposed of in inappropriate ways. The present invention depressurizes an odorant injection system and transfers the unwanted liquid odorant back into an odorant tank where it can be reused when the odorant injection system is restarted.
