Overview of N-Methyl-2-Pyrrolidone (NMp) Recovery Systems

N-Methyl-2-pyrrolidone (NMp) Recovery Systems are specialized HVAC systems designed to remove NMp and other volatile organic compounds (VOCs) as well as hazardous air pollutants (HAps) from industrial process exhaust streams, particularly in battery manufacturing.

NMp is an organic solvent widely used in various industries, including:

  • Battery production: As a solvent for lithium-ion battery cathode materials
  • Hydrocarbon extraction: For lube oil extraction and petrochemical processing
  • Pharmaceuticals: As a drug solubilizer and penetration enhancer
  • Electronics: In formulations for active pharmaceutical ingredients, drug delivery systems, etc.

NMp recovery systems allow manufacturers to meet emission regulations while also enabling the reuse of this valuable solvent, optimizing production costs. The recovery process typically involves extracting and purifying NMp from gas phase streams through techniques like flash evaporation, distillation, and gas stripping. Solvent dehydration is also often employed to prevent water buildup in the recovered NMp.

By implementing these NMp recovery technologies, industrial facilities can minimize waste generation and drive sustainability through the recirculation of this versatile organic compound. The recovered NMp can then be reintegrated back into manufacturing processes, creating a more closed-loop and cost-effective operation.

How N-Methyl-2-Pyrrolidone Recovery Systems Work

N-Methyl-2-pyrrolidone (NMp) recovery systems use three main process steps to extract and purify NMp from industrial gas streams:

1. Adsorption

Exhaust air from lithium-ion battery manufacturing is passed through a zeolite wheel, which captures the NMp emissions at room temperature.

2. Desorption

The zeolite is rotated to the Desorption airflow, where it is heated to 300-400°F, releasing the NMp solvent into a small volume, concentrated air stream.

3. Distillation

The solvents are separated into their components at lower-than-boiling point temperatures, with waste removed and clean solvent left.

The NMp recovery process can enable the reuse of NMp and minimize waste generation. Up to 95 percent of the used NMp can be recovered.

NMp is an organic compound that is a colorless liquid, though impure samples can appear yellow. It is miscible with water and with most common organic solvents. It is used in the petrochemical, polymer, and battery industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials.

What Is The Only Substance That Is Completely Recyclable?

Cans made of aluminum are among the most recyclable materials because they are 100% recyclable and may be processed repeatedly.2. Recycled aluminum cans require 95% less energy to make new ones than new cans do.

Why Is It Necessary to Activate PVDF?

It is significant. In contrast to nitrocellulose membranes that are hydrophilic, PVDF is quite hydrophobic. In fact, the membrane is so hydrophobic that an aqueous buffer, such as a transfer buffer, will not be able to pass through it. Protein cannot transfer and attach to the membrane without activation.

What Is The Most Typical Solvent Used in The Oil Extraction Process?

n-hexaneOil was extracted from oil seeds using the traditional process of solvent extraction. In olvent extraction, n-hexane was used as an olvent due to its strong electivity to olvent, high imple recovery, non-polar nature, and low latent heat of vaporization (330 kJ/kg).

What Does PMMA Dissolve in?

PMMA was dissolved in a solution of MIBK-xylene and chloroform called xylene.

Which Carcinogen Am I Exposed to?

One of the most potent plant carcinogens is cyclin (methylazoxymethanol-glucoside; International Agency for Research on Cancer, 1976; Magee et al., 1976). The palm-like cycad tree belonging to the family Cycadaceae contains this molecule as well as at least one similar glucoide (macrozamin).

Can I Legally Purchase Medicine from Canada?

The FDA permits customers to purchase medications from Canadian online pharmacies and have them shipped to the United States in accordance with the same rules that govern carrying medications across international borders. This indicates that you will require a legitimate prescription from a qualified healthcare professional and that the medication must be authorized for use in the U.S.

The New FDA Injection Weight Limit Is What?

Tirzepatide mimics GLP-1 and GIP, two hormones that are naturally produced in the stomach. When a person is full, a hormone signals to the brain to increase hunger. Wegovy and Ozempic solely attack GLP-1. In a clinical experiment conducted in 2021, patients who took Ozempic lost about 15% of their body weight.

How Long Till Quviviq Starts to Work?

When will it start to work? Within 30 minutes, Quviviq began to assist you fall asleep. Remember that taking Quviviq with food or immediately after eating may cause the medication's effects to last longer than an hour. In the first week of the Quviviq clinical trial, some participants reported sleeping better.

How Can Methanol Solvent Be Eliminated?

According to the invention, methanol can be eliminated by mixing water with the ohexane and methanol solution. This method is simple to use and labor- and time-saving, uses inexpensive deionized water, and uses a mild treatment process without creating any danger.

What Is The Basic Principle of Extraction?

Hexane is a widely used solvent for extraction since it has a low volatile organic content, is safe to use with high-quality products, and emits no unpleasant fumes or odors. All of this made hexane seem like a safe, fast, and simple solvent to use for extraction, especially given its low boiling point.

The way this CloudMassage feels and functions on my legs and feet astounds me. My legs have been hurting, swelling, and feeling uncomfortable for years. I've spent the last thirty years sitting in a wheelchair, which has contributed to this in part. I'm unable to stand or limber. My legs and feet hurt and swell a lot as a result of my limited mobility. In addition to having diabetes, I also exhibit symptoms of diabetic neuropathy, which hurts and keeps me up at night. I required assistance in decreasing the swelling in my feet and legs as well as improving my blood flow circulation. In an attempt to get relief, I have seen many doctors as well as homeopathic, holistic, physical therapists, and other medical specialists. I was told to do more exercise, elevate my legs, move more, and do other things that I was unable to do due to my other health conditions, degree of discomfort, lack of time, and financial constraints. I've spent a lot of time and money on this, but up until now, I haven't discovered a workable answer. I conducted independent research to find my answer. As I looked into solutions to the issues that

My feet have been bothering me a lot lately, and I have Type 2 diabetes. It started off as merely a tingling feeling but has since progressed to agony. Today, I used this for thirty minutes after opening the box. The outcomes were outstanding! I could literally feel the soles of my feet getting itchy. I haven't experienced this feeling in years, but after using some capsaicin cream, the itching disappeared. I've been exercising to reverse neuropathy, as I discovered through study, but this therapy enhances it beautifully by strengthening the muscles following action and supplying them with oxygen. Feels fantastic both during and after. It has numerous settings that allow a variety of massage types, with controls to adjust pressure, speed, and intensity. Strongly advised for the enjoyment and relaxation, especially for those without diabetes.


Well, my feet have never been good. I had to accept using orthotics and having few shoe selections that could accommodate them. I purchased this earlier in the year. I used it religiously at first, and up until August, I wore my Birkenstock sandals. I next purchased some Ariat boots. They don't allow orthotics, but because I didn't seem to require them, I didn't give it much thought. After I purchased Carhartt boots, I didn't appear to experience any discomfort from not wearing orthotics. My feet didn't start aching again until I was walking around barefoot during this snowstorm. Oh yeah, I took this bad guy out. It delves deeply. It pierces my arches in a way that hurts incredibly well. I simply place my feet strategically before beginning the cycles if I want to apply additional pressure to a particular area of my feet, such my heel or ball. Even though I dislike heat, this does get HOT when the heat is turned on. I can run the machine through approximately three cycles without using the heat setting before it becomes too warm and needs a break. To obtain that p, the compression is FANTASTIC.
