Corrosion-Resistant NMp Recovery Systems for Safe And Efficient Solvent Recapture

NMp recovery systems are HVAC systems that remove N-Methyl-2-pyrrolidone (NMp) and other volatile organic compounds (VOCs) and hazardous air pollutants (HAps) from battery manufacturing process exhausts. The systems are made of corrosion-resistant materials, such as stainless steel, and achieve stable performance. They are also designed with a fault-handling device that will not produce backflow or suffocation.

NMp is a solvent used in a variety of industries and applications, such as paint and coating removal, petrochemical processing, engineering plastics coatings, agricultural chemicals, electronic cleaning, and industrial/domestic cleaning. In the battery industry, NMp is used to dissolve nickel, manganese, and cobalt (NMC) powder. Once the NMp powder has been released onto the electrode plates, the material is cooled, condensed, and collected as a waste by-product. Battery manufacturers may use 10,000–20,000 gallons of NMp per month.

NMp solvent recovery systems have the following operating principles:

  • Solvent recovery: Condenses the solvent into a liquid after emission by the coating machine
  • Air purification: Limits the quantities and concentrations of solvent emitted into the atmosphere
  • Distillation: Makes the solvent reusable in the production process

Non-Corrosive Recovery Systems for N-Methyl-2-Pyrrolidone (NMp)

NMp (N-methyl-2-pyrrolidone) recovery systems typically use three phases:

  • Adsorbing: The NMp is captured
  • Desorbing: The NMp is heated and released
  • Condensation and collection: The NMp is cooled, liquified, and collected in a tank for re-use

Liquid NMp recovery can use fractional distillation, which separates NMp from impurities at lower-than-boiling point temperatures. Multi-stage distillation can achieve recovery rates of up to 95% and purity levels of 99%.

Other NMp recovery systems include:

  • Butadiene extraction technology: The vapor leaving the degassing column is cooled, compressed, and sent back to the extractive distillation section.
  • pervaporation: Can effectively remove moisture and methylamine from NMp

NMp recycling systems are often made of stainless steel and other corrosion-resistant materials to achieve stable performance.

NMp is used to dissolve nickel, manganese, and cobalt (NMC) powder. Battery manufacturers may use 10,000–20,000 gallons of NMp per month.

People May Ask

Which Polymers Are The Most Contaminating?

The top-ranking polymers of concern are determined to be PUR, PVC, PAN, ABS, PMMA, SAN, TPU, UP, PET, PS, and HDPE (descending order).

What Threats Do NMP Poses?

The eyes, skin, nose, and throat get irritated with excessive NMP exposure. It can also have an impact on the brain or central nervous system, creating symptoms of intoxication comparable to those brought on by consuming alcohol. NMP absorbs quickly via the skin.

How Does PVDF Become Hydrophobic?

The naturally hydrophobic Polyvinylidene Fluoride (PVDF) membrane has drawn a lot of interest because of its exceptional qualities, which include high thermal stability, excellent mechanical strength, and chemical resistance. As a result, it has good resistance to organic solvents, corrosion, and other things.

Why Is PVDF An Effective Binder?

Due to its good electrochemical stability, wettability with the electrolytes, and appropriate adhesive strength between electrode laminates and current collectors, polyvinylidene fluoride (PVDF) is frequently used as the binder in commercial LIBs.

What Is The PVDF Coating Substitute?

By providing extensive surface coverage by the binding agent to graphite, WL outperforms PVdF and significantly lowers irreversible electrolyte decomposition (EI production) on the material.

Is It Unlawful to Eject Recovered Refrigerant?

The EPA forbids the use of used refrigerant in appliances unless it has been recycled by a reclaimer who has received certification from the agency. Contact an EPA-certified reclaimer or your local refrigerant distributor if you have used refrigerant that you do not need for your own appliance.

What Are The Two Methods for Recovering Refrigerants?

Although less effective than liquid recovery, vapor recovery is still the most used technique. It implies a refrigerant transfer in the vapor state. Recovery procedures for liquids and vapors are fairly similar. The refrigerant's state and how much of it is on the refrigerant recovery unit are the only differences.

What Is The Best Method of Recovery?

Some of the most well-liked athletic recovery techniques include hydrotherapy, active recovery, stretching, compression clothing, rest, and nutrition.

Which of The Four Recovery Types Are They?

Health is the process of overcoming or managing disease and maintaining physical and mental well-being. A table and a safe place to call home. Purpose: engaging daily activities, a stable employment, a good school, volunteer work, and a supportive family. Community is a relational and social network that offers love, support, and hope.

In the hopes that others would see, I gave this five stars. I purchased them and got them three days ago. was eager to give it a shot since my bonus mother claimed that consuming electrolytes gave her energy. I chose this brand, and after drinking it the first day, I had a terrible headache that night (I don't usually get migraines). I didn't think much of it, figuring it might be something else. I drank it again yesterday afternoon, and by then, my heart was racing so much that I was irritated and had to keep taking deep breaths to get rid of the overwhelming feeling of anxiousness I was experiencing in my chest. This had only happened once before, and it was after I had taken some horrible preworkout beverage! Even now, I didn't believe the drink was to blame! "That drink is the only new thing you took!" my spouse pointed out. But since it contains electrolytes, I thought, "No way!" Yesterday, I had a mild headache as well, but the extreme worry and agitation I was experiencing was insane! I therefore made this drink in 60 ounces of water today and drank it all day.


Though my wife doesn't think the same, I adore its flavor. Works wonders for replenishing fluids and provides relief from summertime headaches for me. Many times, taking one or two of these before bed or while drinking has prevented (or at least significantly reduced) hangovers. I always have a supply of these golf and hockey bags at home and in the trailer!

These liquid IV packets are amazing. Early in January, I was sick with the flu and, try as I might, I was unable to hold down water. These taste amazing and kept me well-hydrated. They're also very beneficial if you intend to go out to a bar or club. These are ideal for hydrating after a night out or the morning after when you're not feeling well because we've all overdone it. Simple to operate. Just split apart the small packets, mix them into a bottle or glass of water, and sip. To be honest, these are a little bit sweet, so you might want to try something else if you're searching for something that isn't too sweet, but for me, these have worked great.
