Hydrogen Peroxide and butane interaction

[rb extractors]

So I'm not sure how to broach this and need some clarification on things.

There is someone selling used alcatels that had been formerly used to purge concentrated hydrogen peroxide. Something like 50% or higher strength.

The thing is, these pumps can't be resold unless they are rebuilt and gone through some specific cleaning process, which they aren't.

I know some of you don't vent your exhaust outside but still might be just using a mister and feeling safe, but anything pulled out of your slabs is exhausting through your pump.

I also don't know if butane vapors might interact in a bad way with the hydrogen residue. My pump wholesaler seemed pretty concerned about this. The only reason he figured it out was that someone brought one of these pumps in to be worked on.

Before I out this guy, I'd love to have much smarter people and less sleep deprived thank I to weigh in on this to determine if anything needs to be said.

Sorry if I rambled...3 hours sleep :/

file:///C:/Users/Katy%20Manning/AppData/Local/Microsoft/Windows/Temporary%20Inte... 4/10/2014
(redness), swelling, and the formation of papules and vesicles (blisters).
Ingestion: Causes gastrointestinal irritation with nausea, vomiting and diarrhea. Causes
gastrointestinal tract burns. May cause vascular collapse and damage. May cause damage to the
red blood cells. May cause difficulty in swallowing, stomach distension, possible cerebral swelling
and death. Ingestion may result in irritation of the esophagus, bleeding of the stomach and ulcer
formation.
Inhalation: Causes chemical burns to the respiratory tract. May cause ulceration of nasal tissue,
insomnia, nervous tremors with numb extremities, chemical pneumonia, unconsciousness, and
death. At high concentrations, respiratory effects may include acute lung damage and delayed
pulmonary edema.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Laboratory experiments
have resulted in mutagenic effects. Repeated contact may cause corneal damage.
Section 4 - First Aid Measures
Eyes: Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive
irrigation with water is required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush skin with plenty of soap and water for at
least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Destroy contaminated shoes.
Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or
water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Wash mouth out with water. Vomiting may occur spontaneously. If vomiting occurs and the
victim is conscious, give water to further dilute the chemical.
Inhalation: Get medical aid immediately. Remove from exposure to fresh air immediately. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has
ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag
and a mask.
Notes to Physician: Treat symptomatically and supportively. Attempts at evacuating the
stomach via emesis induction or gastric lavage should be avoided. In the event of severe
distension of the stomach or esophagus due to gas formation, insertion of a gastric tube may be
required. To treat corneal damage, careful ophthalmologic evaluation is recommended and the
possibility of local corticosteroid therapy should be considered.
Section 5 - Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressuredemand,
MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can
cause environmental damage. Dike and collect water used to fight fire. Strong oxidizer. Contact
with combustible materials may cause a fire. During a fire, irritating and highly toxic gases may
be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed
containers cool. Substance is noncombustible. Use water with caution and in flooding amounts.
Vapors may be heavier than air. They can spread along the ground and collect in low or confined
areas. Some oxidizers may react explosively with hydrocarbons(fuel). May decompose
explosively when heated or involved in a fire. May accelerate burning if involved in a fire.
Extinguishing Media: Use water only! Do NOT use carbon dioxide. Do NOT use dry chemical.
Do NOT get water inside containers. Contact professional fire-fighters immediately. Cool
containers with flooding quantities of water until well after fire is out. For large fires, flood fire
area with large quantities of water, while knocking down vapors with water fog.

[Rickys bong]

Hydrogen peroxide? you sure about that? H2O2 isn't a gas... Minor amounts of H2O2 vapor would simply decompose the oil and not stay dissolved. Hydrogen gas dissolved in pump oil alone won't react with butane.

Maybe it was something else? (please don't paste MSDS sheets...)

If it's some nasty shit like hydrogen sulphide the pumps would smell so bad you wouldn't want them anyway...

 

[Gray Wolf]

I wouldn't mix H2O2 and the hydrocarbons, but as Rickys b points out, unreacted H2O2 vapors would be scarce, if at all after an oil change.

 

[C'Ya]

H2O2 can be used to remove mercaptans from hydrocarbons, But I am unsure if it will remove terps from a pump in same manner.
here's a link regarding the merc removal if interested in reading.
http://www.h2o2.com/industrial/applications.aspx?pid=110&name=Mercaptan-Control

 

[C'Ya]

oh sorry didn't read your first post correctly thought it was regarding cleaning pump with h2o2 my bad

 

[C'Ya]

From tests I did do the h202 broke down the mercs in propane and resulted in some oxygen being released with the propane during the oxidizing processes of breaking down the mercs leaving behind water with only a slight hint of mercs. Cleaned gas sample was mild smell like when burping tank of air.
Not sure if that helps answer your question

 

[rb extractors]

I would have thought it would dissipate, but apparently not

 

[C'Ya]

Like GW and Ricky pointed out a oil change or two should remove the h2o2 or h2o that condensed in the oil, the released gases from the oxidizing stage should dissipate, main reason I'd suggest to disassemble is to remove any oxides that build up on the internal parts and if you've ever pulled water into a rotary vane vac pump it makes it knock bad, so I'd want to make sure no damage was done from water left behind in the oil
