Great video I have 2 dounts Is this process is same for all the types of pellets produced in industry ? What is the reference material to know different polymer production process
Hello it's fantastic presentation. In my country we got all raw material necessary. But there isn't company for polypropylene. Me I want to create with partnership.
This is great. May I know what is the chemical reaction happening in this polymerization? Probably chemical equation that shows how it converts from propylene to PP using this technology?
Ethane from natural gas Ethane can be converted to ethene (via dehydrogenation reaction) Ethene can be polymerized into ethylene, PP or anything you want. Here’s a good video that relates directly with your question: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C7EwPX7312k.html
Had to go through way too many videos to find this. They explain everything up to this step, and then just say it's refined into plastic pellets without elaborating at all. Thank you for explaining this so well!
This is only one type of gas phase polymerization technology for one type of polymer (polypropylene). Therefore, there are many polypropylene production processes that include but not limited to “ Novolen®, Unipol® (gas-phase processes), Borstar® and Spheripol® (liquid-phase processes).” For other polymers (and there are many, believe me!) there are multiple different technologies for each. These technologies differ in the investment/capital cost, operation cost and different grades produced within a polymer Grades portfolio. The reason for these different technologies for different polymers is companies usually, through IP laws, protect their technologies and only allow non-competitor companies in a market where a technology owner company sell/operate in, to use their technology by a practice called “technology licensing-out”. So another competitive company, after a series of economical, legal, marketing, and technical studies, invest in R&D to develop another technology to produce a same or a better product of a polymer. Btw, this’s the tip of the iceberg, because there are also within these technologies different catalysis systems or initiators that produce different grades, different polymer processing technologies (i.e. extrusion, injection molding, compression molding, and rotational molding technologies). I apologize for my bad English because I am not a native English speaker. Thank you OP and greetings from Saudi Arabia 🇸🇦.
@@inorite4553 Good for you, but the title is “how polymerization works...” so they generalized polypropylene gas phase process (i.e. Novolen process) on all polymer manufacturing processes. That’s why I wrote my comment I am tired of people not familiar with the industry telling about polymer manufacturing and how harmful is it.
@@mycosys nothing is black and white. It’s a good concept but needs limitations on what inventors/owners can claim in their IPs. They think they are circumventing legal loopholes by claiming everything from catalysts, reagents, and the whole processes (i.e. from raw material and until granular resin and wastes), which I am fine with until this point, but to claim products’ properties! This is a bit too much, if you ask me. Note/ I am far from being a legal expert in IP laws, I’m just voicing my concerns only when it comes to polymer manufacturing. Other than that I am novice in IP laws.
Adding water makes the powder a liquid substance. (like adding water to pancake mix so it can flow). This reduces the friction of the substance through all of the moving parts.
