![]() This is an excellent piece of equipment that nearly perfects the efficiency of gas cleaning, even separating iron sufides, parrafins, and glycols from the gas stream. The filter elements in this single-stage type unit can be cleaned by back-flowing while the vessel is in full service. Also, odorants are considered nontoxic at the minuscule concentrations that an end-user may encounter.The KingTool Automatic Self-Cleaning Reverse Flow Mist Coalescer with Integral Slug Interceptor removes entrained solids and liquids from gas by means of dry-type molded fiberglass filter elements. According to experts in the field, combusting the odorized gas does not create any severe sulfur content or toxicity problems. Given that the lower explosive limit for natural gas is approximately 5%, the gas must be detected by smell when the gas reaches around 1% of gas in the air. How much odorant is added to the gas? The regulations state that distribution lines of any combustible gas contain a natural odorant, “so that at a concentration in air of one-fifth of the lower explosive limit, the gas is readily detectable by a person with a normal sense of smell.” A combustible gas in Class 3 or Class 4 locations must meet odorization levels, with some exceptions spelled out in the regulations for transmission lines. When introducing trace amounts of organic sulfur compounds into portions of gas transmission and gas distribution lines, the gas smells. Pictured is a portable odorant injection system with odorizer, tank, and containment – from GPL Odorizers. ![]() Today, federal regulations mandate the odorization of natural gas. The natural gas industry goes through great efforts to safely deliver this fuel from the wellhead to the burner. Following the accident, Texas and other states adopted standards to regulate the odorization of natural gas. In 1937, in London, Texas, natural gas ignited and blew up a school, killing nearly 300 children and teachers. The impetus behind odorizing natural gas goes back to one of the worst tragedies in U.S. One of the processes in natural gas transmission and distribution is gas odorization, which adds an odorant to natural gas so people can smell it. Being an extremely volatile hydrocarbon and not easy to recognize – it makes a dangerous combination. Contrary to what most people believe, natural gas in its natural state is tough to detect, given that it is odorless. While most people associate natural gas with a rotten egg smell, what causes the strong odor is natural gas odorant. This technique occurs for safety reasons. Odorization is the process of introducing an odorant into a gas stream to make the gas detectable through smell. ![]()
