Liquid contamination also hinders the evaporative process. If water is a contaminant, even at 0. These odorizers also need to have their sight glass checked every month. While it is easy to refill the tank with the odorant, a significant amount of odorized gas releases into the atmosphere during each refill. As injection-type odorizers become more cost-effective to service smaller systems, the bypass odorizer will become obsolete.
Due to the disadvantages of the vaporization or evaporation odorization systems, manufacturers have introduced mutations. A couple worthy of mention:. One manufacturer created a design similar to the wick-odorizer with two pitot tubes instead of the wick. This model performed well in the summer months, though it failed in temperatures below freezing. The bypass odorizer was modified to permit tracking natural gas flow.
In this case, the higher pressure gas from a transmission line is used to introduce odorant vapors into a lower pressure distribution line.
By diverting non-odorized natural gas through an odorant tank, the saturated gas returns to a downstream distribution line. This style is suitable for lower volume applications, and while it is more expensive than the traditional bypass, it offers cost incentives versus feature-rich injection systems. In our next post, we share information on chemical odorant injection odorization. Natural gas odorization is the process of injecting an odorant into a gas stream by an odorizer or odorant injection equipment.
The purpose, of course, is to make the gas smell so that it can be detected, because, in its natural state, natural gas is odorless. The most common odorant added to propane is ethyl mercaptan. Natural gas is odorized with an odorant which is typically a blend of various organosulfur or non-sulfur compounds to make it smell like rotten eggs or hydrogen sulfide.
That nasty, rotten-egg smell commonly associated with natural gas is added to gas so that people can detect it and take the appropriate action, which may include leaving the area and calling I have a farm tap type gas well. Can I buy odorant for my wick type odorizer by itself, or do you buy the entire canister? In either case, do you sell these items?

By adding small volumes of liquid odorant into flowing gas, the gas becomes odorized. In this odorant injection style, a computer controller monitors the flow, which will vary the injection rate. Two standard vaporization systems are the wick-type and bypass-type. The wick-style system is one of the oldest types for low volume applications of less than SCFH. They are for camps, trailers, instrumentation leak detection, and domestic farm taps.
These small units are installed on a service line near the gas meter. A wick inserts into the odorant and becomes saturated, and the opposite end extends into the gas stream. The odorant draws up the wick and evaporates into the gas, creating the desired smell. The bypass unit is for a small or low-volume system.
In this process, part of the gas stream diverts to a tank containing liquid odorant. Most of these systems include wicks to increase vaporization.
