Dear All,

 

Do you know any method allowing neutralization of off-spec ethylene oxide in other way than reprocessing in EO plant?
Maybe there are any related regulations or standards.

 

Regards

Movers,

 

This is an excellent question for AI.  I asked Google AI, "what markets is common to purchase off-spec ethylene oxide?"  It said,

 

"Off-spec ethylene oxide (EO) is commonly purchased by industries that can tolerate lower purity levels for derivative production, including the manufacture of industrial surfactants, specialty detergents, and some agricultural chemical formulations. These markets often use lower-grade feedstock for non-sterile, high-volume applications like textile auxiliaries and pesticide solvents. 

 

Key markets that often utilize or can repurpose off-spec EO include:

• Industrial Surfactants & Detergents: Manufacturers producing surfactants for industrial cleaning or processing where high purity (common in personal care) is less critical.
• Agrochemical Formulations: Production of emulsifiers and solvents for pesticides, herbicides, and fertilizers.
• Textile Processing: Manufacturers of textile processing chemicals, such as surfactants used in dyeing and finishing.
• Polyethylene Glycol (PEG) Production: Lower-grade PEG used in industrial applications, such as lubricants or dispersants, rather than for pharmaceutical or cosmetic use.
• Adhesives & Resins: Production of specialized resins and adhesives where slight impurities do not affect performance. 

These industries often procure off-spec materials to reduce costs in high-volume, non-sensitive applications."

 

You should give AI a try.

Thanks for response.

 

Unfortunately my question was not precize. I am looking for method of neutralizing not very big amount of ethylene oxide (e.g. railway tanker) in emergency situation (off-spec, temperature excursion, etc..).

Hi,

The realistic way to solve your problem is to "dilute the off-spec product" in the on-spec stream. This is only a matter of time.

Ask your process guy to define the correct ratio with the support of the lab.

BTW we have no clue about how bad your product is!

Thanks.

 

The thing is that I trying to avoid reprocessing off-spec with on-spec material. In our situation such solution will require much investment costs.

Hi,

Based on experience, don't try to play with the chemistry, you will never get the product on spec with all the properties associated. This will be a waste of time and money.

I really don't understand your story about Capex.

As other said try to find a market where this product could be sold at a discounted price.

Latexman and I have a lot of experience with this kind of issues.
