Discussions took place to add a smell, which would be suitable and meet the Gas Acts requirements. Additionally, many of the coal gas pipes were reused which retained the distinct coal gas odour. This meant the reformed gas also retained the familiar warning smell the public were accustomed to for a limited amount of time.

MercapMan is here to educate the industry and public on the importance of odorizing natural gas. Suse September 10, Almost every kid in town — gone. David Grimes February 15, Phil October 25, JIM March 27, Kelly April 5, I was wondering the same thing and cannot find an answer anywhere. Scarlet Rose July 29, Senator April 25, Charles Grider September 16, The impetus behind odorizing natural gas goes back to one of the worst tragedies in U.
In , in London, Texas, natural gas ignited and blew up a school, killing nearly children and teachers. Following the accident, Texas and other states adopted standards to regulate the odorization of natural gas.
The natural gas industry goes through great efforts to safely deliver this fuel from the wellhead to the burner. Today, federal regulations mandate the odorization of natural gas.
Pictured is a portable odorant injection system with odorizer, tank, and containment — from GPL Odorizers. When introducing trace amounts of organic sulfur compounds into portions of gas transmission and gas distribution lines, the gas smells. How much odorant is added to the gas? According to experts in the field, combusting the odorized gas does not create any severe sulfur content or toxicity problems.
Also, odorants are considered nontoxic at the minuscule concentrations that an end-user may encounter. The instrumentation accurately doses natural gas streams throughout various production phases, transmission, and distribution with odorants belonging to a group of organosulfur compounds. It is these compounds that give natural gas its distinct odor, as mandated in federal safety guidelines. Are you interested in odorant injection systems?
Ask Here! I am happy that you simply shared this useful info with us. Please stay us up to date like this. Tetrahydrothiophene THT , an organic sulfur compound with an intense odor, is used as the odorant. Not only is the OD the largest odorizing system ever produced by LEWA, but it is also currently the largest of its kind in Germany.
The following properties make the OD an optimal solution for the application at the hub of the gas network:. Natural gas odorization is an important safety measure, not just for gas purchasers and customers.
Formerly used city or cokery gases had a strong intrinsic odor and rarely required odorization. Meanwhile, the commonly used natural gas is cleaned and almost odorless. In order to be able to immediately detect leakage in the gas network, the natural gas odorization is mandatory as a safety measure. The gases added during the odorization generate specific warning odors.
The odorants used in the odorization of natural gas must fulfill special safety requirements. Their odor must be perceptible even at a high dilution, and unmistakably induce the association with gas leakage.
The odorant must therefore smell unpleasant and distinctive. In Germany, volatile organic sulfur compounds are frequently used as odorant. Their typical savor is evocative of the smell of rotten eggs. Frequently, also mercaptan mixtures are in use. There are also odorants free of sulfur. Unlike the odorization with the sulfur-containing substances THT or Mercaptan, sulfur-free odorants have the advantage that no additional sulfur oxides are formed during the combustion of natural gas.
The equipment used to infuse the odorant into the gas stream is a natural gas odorizer. Odorizers are designed based on one of two principles, either chemical vaporization or chemical injection. The vaporization equipment includes wick-type odorizers and bypass odorizers along with some other less popular variations.
As your partner in odorization, we pride ourselves in the ability to troubleshoot, repair, or complete preventative maintenance on all Odorization equipment. We're not around right now. But you can send us an email and we'll get back to you, asap. About Odorization What is natural gas odorization?
