What if I need less than 5,000 gallons? Can you help?
What type of odorant blends can be used in injection systems?
Any odorant blend can used since it is being injected directly into the gas flow. Differences in component vapor pressures do not affect performance
What type of odorant blends can be used in evaporative systems?
Single component odorants, e.g., THT, or blends where components have similar vapor pressures, e.g., all mercaptan blends or blends with TBM and MES, can be used in evaporative systems. Do not use mercaptan/DMS or mercaptan/THT blends. The components in these blends have widely differing vapor pressures, which results in inconsistent odorization of your gas.
What type of packages does Odor-Tech offer?
Odor-Tech can supply you bulk needs using our diverse fleet of trailers, from a remote 100 gallon storage tank to a high volume 10,000 gallon tank. Our partner Bayou Engineering offers various cylinders, pails, and drums to meet your needs.
Am I using the odorant blend best suited to my needs?
Please see Skunk Tip on Blend Rationalization to answer this question.
If I change my blend, will I experience any compatibility problems mixing the new blend with the blend currently in my storage tank ?
No. All blend components are soluble in each other.
Will they react?
No. Mixing will not diminish their effectiveness as odorants. There will be no reaction!
Will a different blend be compatible with the materials of construction used in my storage tanks and injection equipment?
Yes. The same materials of construction are recommended for all odorant blends.
We are installing a new odorant storage tank at one of our stations and our old tank is half full of odorant. Can you help?
Yes! During an odorant delivery to a number of your stations, we can transfer the odorant from the old tank to the new tank on site or to another tank off site if the old tank is not being replaced.
What is a "closed loop" delivery? Are there any advantages over the traditional flare delivery ?
In a flared delivery, a liquid hose is connected to a liquid line on the tank, which is preferably fitted with a dip-tube. The vapor line on the tank which is connected to the flare is opened to vent off any pressure. Pressure is applied to the odorant trailer and the liquid valves are opened to allow flow to the storage tank. The displaced vapors from the tank are vented to the flare until the delivery is complete. These vapors burn in the flare and are emitted as sulfur dioxide, which raises environmental issues. Additionally, if the tank has a faulty level gauge, it is possible to overfill the tank with odorant, which will cause overflow through the flare resulting in odorant spillage. This is an environmental problem and also results in false leak complaints.
In a "closed loop" delivery, a vapor hose is connected to a vapor line on the tank in addition to the liquid hose. This is done through the truck manifold which is connected to a compressor, which pulls pressure off the tank and supplies it to the trailer to allow flow by differential pressure. This allows the delivery to take place without venting to the flare. Also, when performed correctly, a closed loop delivery removes the chance of tank overfill, and the overall result is a safer, “odor free” delivery.
We have installed a new storage tank. What do we need to do prior to receiving our first odorant delivery?
- The first thing to do is to ensure that the tank and fittings have been properly installed according the design blue-print, ensuring safe storage of your odorant.
- Ensure that the tank is clean and dry. Water in the tank can find its way into your injection lines and in winter conditions can freeze, stopping odorant flow to your gas. Pressure test the tank and check for any leaks at flange connections, valves etc.
- Finally, purge the tank with nitrogen or gas to remove any oxygen. Odorant vapors and oxygen can form explosive mixtures.
What is the maximum volume or weight that can be delivered in a tank truck?
Depending on the blend density, 5,500-6,000 gallons can be delivered by one truck. Of course multiple truck deliveries are available.
What if I need less than 5,000 gallons? Can you help?
Of course. Our odorants team will work with you to ensure efficient and timely delivery of any size order.
