Course Description
In this course, Alkylation and Desulfurization, you will learn about the chemical process of alkylation used in the oil industry. You will learn about the types of catalysts for the reaction and their temperature requirements. We will discuss isobutane, the raw material used in refinery alkylation processes, as well as olefin for raw materials.
We will discuss the variables that control an alkylation process, which are the isobutane to olefins ratio, the reaction temperature, the acid to hydrocarbon ratio, and the acid concentration. You will learn about the hydrofluoric acid process and the sulfuric acid alkylation process, as well as their related control valve guidelines. We will also explore the concept of hydrotreating to remove pollutants that can have negative effects on equipment, catalysts, and the finished product’s overall quality. Finally, you will learn about desulfurization in the refining process.
What You'll Learn
- Explain the chemical process of alkylation used in the oil industry
- Identify the catalysts used for the alkylation reaction and their temperature requirements
- Describe the variables controlling the alkylation process, including the isobutane to olefins ratio, reaction temperature, acid to hydrocarbon ratio, and acid concentration
- Compare the hydrofluoric acid process and the sulfuric acid alkylation process along with their control valve guidelines
- Explain hydrotreating to remove pollutants affecting equipment, catalysts, and product quality
- Describe the desulfurization process in refining, including sulfur recovery and sulfur facilities
Key Takeaways
- Alkylation is a chemical process used in the oil industry that relies on catalysts with specific temperature requirements.
- Isobutane is the raw material used in refinery alkylation processes, alongside olefins as raw materials.
- The alkylation process is controlled by four variables: the isobutane to olefins ratio, the reaction temperature, the acid to hydrocarbon ratio, and the acid concentration.
- Refinery alkylation can use either the hydrofluoric acid process or the sulfuric acid alkylation process, each with its own control valve guidelines.
- Hydrotreating removes pollutants that can negatively affect equipment, catalysts, and the finished product's overall quality, supporting desulfurization in refining.
