Applications of hydrogen! ! ?

Experts, I’m curious about how your company handles hydrogen If we simply empty it like we do, it’s indeed a waste, but we can’t find a suitable processing method. Is there any good technique that could solve this problem? 3Q Last edited by limingshuguang on 2007-12-20 12:16 ] # ， ， &
The hydrogen in our company is used to produce hydrochloric acid and PVC.
The hydrogen in our company is used to produce hydrochloric acid and PVC.
When released into the atmosphere as well, considering the high costs of collection devices and such, it is not cost-effective to recycle hydrogen in this case
We mainly produce HCl and PVC as well
Two treatment methods: First, use a pipeline to connect to a self-owned power plant； II. Production of hydrochloric acid.
Generally, if it’s not useful, it’s just left unused; of course, it depends on whether there are any downstream products and what they are. It’s different in the case of trichlorosilane
Synthesize hydrochloric acid, use as fuel, and vent
Our company deals in hydrochloric acid, materials used for polyvinyl chloride synthesis, hydrogen peroxide, and sapphires
Here we produce hydrochloric acid for use in SBR hydrogenation processes downstream; the pressure levels are 0.1 and 0.5 MPA respectively. Different requirements for water content
If a large amount of steam is required, an exhaust gas boiler can also be added
Direct venting is an option; considering the boiler is also possible. Last edited by limingshuguang on 2007-12-21 13:12.]
The few options available at the moment are: producing HCl, hydrochloric acid, and venting it. Personally, I think venting it is a waste; hydrogen is a very good fuel that should be utilized
It’s a shame. We have been looking for hydrogen. It is relatively good for producing m-phenylenediamine. With Wanhua, the largest domestic user of aniline, having completed and put into operation its 360,000-ton aniline plant in Ningbo, there will be an even greater surplus of aniline in the domestic market. However, in China, only two or three companies are currently producing phthalic aniline. According to reliable sources, one of these companies is about to relocate, and once it does so, it will no longer be able to produce phthalic aniline. At present, the profit margin on this compound is as high as 7,000–9,000 yuan per ton, so starting production of phthalic aniline is a very good option.
Yes, it’s either used to produce HCl or released into the atmosphere – it depends on what is being produced
Hydrogen peroxide can be considered, especially with hydrogen from ion-exchange membrane caustic soda as the best raw material.
If the company has no downstream products that use hydrogen and does not produce hydrochloric acid, it is more economical to discharge it. However, it is recommended that companies develop on their own or in collaboration with other companies products that utilize hydrogen as a raw material, such as hydrogen peroxide and aniline, among others.
It can be sent to the boiler; back in the fertilizer factory, the gas produced was used as fuel in the boilers. The main component of this gas is hydrogen, and an excess amount of hydrogen can also be fed into the boilers, which helps to save energy and reduce consumption.
