Static mixers for mineral extraction processes

There are many chemical processes in which concentrated sulfuric acid (H2SO4) must be diluted to the required concentration. Applications can be found in the chemical industry, in scrubbers, but also in the in-situ extraction of minerals.

Safe mixer with good temperature control

Diluting concentrated sulfuric acid is an exothermic reaction. Because the injection point of a PRIMIX static mixer is positioned directly in front of the first mixing element and due to the flow profile of the mixing elements an immediate and full mixing takes place no hotspots will occur. This totally avoids overheating and possible damage to the plant. The design of the PRIMIX static mixer is precisely matched to the expected (and maximum) temperature increases, creating a very reliable process. As the diluted sulfuric acid concentration is very homogeneous at the outlet side of the mixer, downstream installations are not locally exposed to different concentrations of sulfuric acid. This will contribute to improved safety and durability of the entire system.

Cost efficient static mixer - materials

The PRIMIX static mixer for sulfuric acid applications is made from PTFE-coated carbon steel or stainless steel. This material and due to the unique construction shape the PRIMIX mixer provides a very good resistance to the corrosive action of highly concentrated sulfuric acid. No expensive materials, such as Hastelloy^® C276  are required, which ensures that the mixer is very cost efficient. Since the injector is an integral part of the mixer it can immediately be used in the installation.

In-line dilution - dimensioned to the process

The static mixers for sulfuric acid are completely tailored to your process and available from large (500 mm) to small diameters (up to 25 mm). PRIMIX also supplies static mixers to dilute acids in Pilot Plant facilities. These mixers are often executed in Hastelloy^® C276 and can be supplied depending to the process as small as 4 mm in diameter. These mixers are fully scalable to future process plants.

Globally proven

The PRIMIX concentrated sulfuric acid diluting mixer has been used in hundreds of installations worldwide and has certainly proven to be reliable and safe operation over the years. A lifetime of over 10 years certainly no exception!

Due to rising fuel prices and more strict environmental rules, biofuels are increasingly popular. This increases the demand for equipment that can produce high-quality biofuels such as biodiesel.

Biodiesel production - solution for consistent mixing and temperature control

PRIMIX manufactures static mixers / heat exchangers that are tailored for biodiesel production. Not only do they provide a consistent mix of the diesel, vegetable oils and the catalyst, but they also provide an optimal control of the process temperature.

Additional advantages of the PRIMIX static mixer / heat exchanger;  

• In-line mixing in a continuous process
• Option for multiple injectors (Interference oils and catalyst)
• Easy to build into existing pipe
• Short installation length
• ATEX Ex II 2DG certified (option)
• No mechanical or electrical components
• Very homogeneous temperature distribution within the process
• Explosive and potentially toxic process media are reliably mixed and heat-treated
• Proven track record in bio fuels, tank farm mixers and ULSD production

Partly because of the operational benefits, the number of systems used in the biofuel industry grows steadily. To further inform the industry PRIMIX has released a case study sheet for this specific application. Download the data sheet on the following page: Static mixers for biodiesel production.

Recently, PRIMIX has acquired an Achilles FPAL registration next to their JQS registration.

The JQS and FPAL registration are filled under registration number 300 072 376.

Achilles FPAL/ JQS identifies, evaluates and qualifies suppliers on behalf of large purchasing organizations in the oil and gas industry. The proven pre-qualification system FPAL and JQS enables the procurement departments in the oil and gas sector to assess and qualify suppliers and thus minimize the risk in their supply chain. It also allows the 'best practice' across the industry.

PRIMIX enhances confidence as a reliable supplier of static mixers and heat exchangers

In response to the successful registration, Robert Jan Wakkers, Commercial Director of PRIMIX, said: "The energy that we have been put into obtaining the registration is more than worth it. With this registration our accurate and open way of working is once more proven and established. For our customers in the oil and gas industry it is easier to assess PRIMIX having the confidence that they are dealing with a qualified and reliable partner. We are convinced that this certification will contribute to our continued global growth and that confidence in the PRIMIX static mixers and heat exchangers will be further enhanced."

The certificates can be viewed on our download page. More about the PRIMIX solutions for the oil and gas industry can be read on the page industries: Static Mixers for the petrochemical, oil and gas industry
