Organic compounds, including asphaltenes, can cause severe fouling problems in crude unit operations as crude oil is processed into valuable products for road fuels, aviation fuels and chemical feedstock. As refiners look to improve operations, reduce costs, and increase efficiencies, they may process as many as twenty-five different crudes in a year to meet market demands.

Fouling of heat transfer surfaces, including crude hot preheat exchangers, as well as furnaces and coker heat transfer equipment can cause increased maintenance costs for cleaning equipment, and in severe cases unscheduled shutdown resulting in lost opportunity due to crude throughput loss.
Nelson Brothers manufactures a range of surfactant based dispersants that can be used in your antifoulant formulations. We can customize the size of the PIBSA molecule to meet your requirements and derivatize the PIBSA for specific applications such as asphaltene deposition or general organic deposition in crude unit hot preheat trains. Dispersants for other fouling problems in other processes heat transfer equipment are also available.
The company is the world’s best PIBSI Dispersant supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
This compound is made by reacting polyisobutylene (a polymer) with maleic anhydride to form polyisobutylene succinic anhydride. This anhydride is then reacted with a polyamine, typically an alkylene polyamine, to produce the succinimide dispersant.
The primary function of polyisobutylene succinimide dispersants is to prevent the agglomeration or clumping together of particles, ensuring that these particles remain finely dispersed within the fluid. This helps maintain fluid stability, improves cleanliness, and prevents the formation of deposits or sludge that could otherwise hinder the performance of lubricants or fuels in engines or machinery.
It’s a crucial component in many lubricant formulations to enhance the efficiency and longevity of engines by keeping the internal components clean and reducing wear and tear.
