Which gases require toxic and flammable gas detectors?
Thread Content
The design specifications for the detection and alarm of flammable and toxic gases in the petrochemical industry only list a portion of them. What kinds of gases are generally required to have gas detectors installed? Are there any specific standards, such as regarding boiling points? The process usually focuses on the hazards associated with the medium in question, but many of these mediums are liquids with boiling points of over 100 degrees or even 200 degrees – is it then necessary to use gas detectors? A confused beginner seeking help……
I have the latest version from 2009; I’ll send it to you via email
By the way, what’s your email address?
The flammable and toxic gas alarms I have installed include those for hydrogen and chlorine (used in ion-exchange membrane caustic production)
It depends on the relevant regulations from 2009! It is said that there are new regulations for design now
What poses a problem for me are the toxic substances; under normal processing conditions they are in liquid form, with boiling points around 100 degrees or even higher. However, some of them have a low flash point. In such cases, is it necessary to install gas detectors?
For the ion-exchange membrane caustic soda project, both hydrogen and chlorine need to be monitored. The other details are not clear; the friend mentioned above has the relevant guidelines. Send it to the email liveyousee@126.com
Chlorine, ammonia, gas, CO, hydrogen sulfide, etc. are acceptable.
It probably depends on the medium classification as well, there are categories like Class A, etc
The specifications have been sent to your email; please check it.
The toxic gases listed in the standard \"SH 3063 Design Code for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Enterprises\" include carbon monoxide, vinyl chloride, hydrogen sulfide, chlorine, hydrogen cyanide, acrylonitrile, and ethylene oxide. These gases require the installation of toxic gas alarms.
