Trimethylaluminum, also known as TEAL in the petrochemical industry, catalyzes olefin monomers or alkenes polymerization. This organoaluminum compound acts as a cocatalyst in Ziegler-Natta polymerization to produce polyethylene and other polyolefins. TEAL is crucial in the production of the following:
Due to its high reactivity and volatility, TEAL applications demand very safe and accurate dosing. It is pyrophoric, meaning it causes spontaneous ignition when it comes in contact with air and water. For this reason, Milton Roy dosing pumps, with their specific zero leak design can handle highly reactive and corrosive substances and hence play an important role in critical TEAL applications.
Milton Roy is an industry-leading producer of chemical dosing pumps and a major supplier of the petrochemical industry worldwide. Let’s understand the TEAL applications and the role of Milton Roy pumps in these processes in detail.
TEAL is highly reactive, which is why it's used as a catalyst for polymerization reactions in the petrochemical sector. It’s used to make various commonly used products, such as your regular plastic bags, plastic for toys and automotive parts, etc.
It’s also a reducing agent of choice for producing aluminum alkyls, ketones, and aldehydes.
It also removes sulfur through hydrodesulfurization (HDS) and other impurities in petroleum fractions while refining crude oil. TEAL and sulfur compounds in the petroleum fractions react to produce aluminum sulfide solids. These solids can be easily removed to give refined products, such as diesel and gasoline.
Since TEAL has a very low flashpoint, it combusts when it comes in contact with air and water. Therefore, this reactive nature demands careful handling and appropriate chemical dosing pumps.
When choosing TEAL pumping equipment, you must select a chemical dosing pump designed to:
To ensure the dosing pump can withstand dangerous chemicals and offer a long lifespan, it’s recommended to be built with:
The chemical dosing pump you choose must comply with the American Petroleum Institute (API) 675 standards for the polymerization process.
Milton Roy dosing pumps built for the petrochemical industry are designed with highly reactive and corrosive materials like TEAL in mind. Milton Roy pumps come with essential features for TEAL applications, such as:
Here are the two most popular Milton Roy pumps suitable for critical TEAL applications in polymerization reactors, refining processes, and chemical synthesis:
PRIMEROYAL metering pumps provide extremely precise dosing control with a steady-state accuracy of +/-1% and a nominal flow rate range of 10 to 100%. This series is particularly suited to injecting many different corrosive and reactive fluids, such as TEAL and sulfuric acid, and is particularly useful in the petrochemical industry.
2. MILROYAL Series Pumps
The MILROYAL® series metering pumps are the most reliable, industrial-duty metering pumps for critical processes in industries such as oil and gas, chemical, and petrochemical processing. These pumps offer leak-free performance at pressures up to 1380 bar. Few models of Milroyal are Dynamic Stiffness Diaphragm (DSD) Technology enabled for consistent performance even at lower injection rates.
