What are the latest standards for qualifying gas replacement? Is the detonation test still being used?
I think it’s not necessary in many cases; for example, after the coke oven stops heating, gas can be supplied again by using steam to purge it, and gas can be introduced as long as white vapor appears at the vent pipe.
The view expressed above is a common illegal practice in the modern chemical industry; for safety reasons, it is best to conduct blasting tests.
Yes, this method is still widely used in coking plants; it is simple, fast, and effective. However, there is also a quantitative method that is widely used, namely oxygen content analysis; a level of oxygen content below 2% is considered acceptable. This method is just more complex and requires more time. Of course, there are also advanced methods available that are both quick and quantitative, though the investment is slightly higher; one can use imported (for example, German) portable gas composition analyzers that provide results immediately.
I don’t know if it’s used elsewhere, but I’ve always used this method here
I’ve been using this one as well; it’s the safest option
Simple and practical; not used by large companies in general, gas chromatography analysis is employed
