The process is referred to as a  (SAAU) or a , (HFAU). However, oil refinery employees may simply refer to the unit as the Alkyl or Alky unit. The product is called alkylate and is composed of a mixture of high-octane, branched-chain paraffinic hydrocarbons (mostly isopentane and isooctane). Alkylate is a premium gasoline blending stock because it has exceptional antiknock properties and is clean burning. Alkylate is also a key component of avgas. The octane number of the alkylate depends mainly upon the kind of olefins used and upon operating conditions. ### ALKYLATION - SULFURIC ![](https://info.techstar.com/hubfs/image-png-Oct-15-2021-08-20-13-15-PM.png) ### ALKYLATION - HF ![](https://info.techstar.com/hubfs/image-png-Oct-15-2021-08-24-09-95-PM.png) TechStar Analyzer Solutions can assist your Alkylation Units with: - **Used to control the proper Iso-Butane to Olefin ratio in the reactor** - **Control recycle impurities to maintain the proper Iso-Butane to Olefin ratio in the reactor** - **Control RVP when Alkylate is being blended with Gasoline** - **Reduce product Impurities** - **Reflux control** - **Prevent carry-over and loss** - **Measuring O2 in furnace** - **Combustion Control** - **Safety** - **Corrosion Protection** #### SOLUTIONS: ### PROCESS GAS CHROMATOGRAPH [![Yokogawa GC8000](https://info.techstar.com/hs-fs/hubfs/2O6A9242.jpg?upscale=true&upscale=true&width=159&name=2O6A9242.jpg)](https://info.techstar.com/yokogawa-gc8000)Over the past 60 years, GC products from Yokogawa have continued to evolve to meet the ever-changing needs of the process industry. Engineered with reliable electronics and intelligently designed columns & valves, the GC8000 improves ease of maintenance while reducing operating costs.
