Optimise your alkylation process and take control with the Profiler™ TGA

The Challenge. Alkylation processes present some of the more challenging applications for interface measurement and control in refinery operations. It is important for the operator to have confidence in the process to optimise alkylate production, while ensuring safe operation and environmental compliance.

In a settler, not knowing the levels of hydrocarbon, emulsion and alkylate with confidence can cause problems, including increased polymer formation and combined fluorides, as well as reduced alkylate production. Without knowing how much acid there is in the system, it cannot be determined how much is lost via depropaniser overhead, flaring sources and acid regenerator bottoms. Being able to see acid content can enable operators to establish if there is an acid loss problem, and help troubleshoot the source.

Poor interface and level control creates the need for operators to manually monitor the levels, and increases the probability of exposure to acid and leaks from manually operated try-cock valves. In addition to safety, there are process and environmental issues, such as carry-over and carry-under. Acid carry-over from the settler with hydrocarbons increases downstream failures such as corrosion in the depropaniser inlet, increased load on downstream acid recovery processes, increased acid consumption, and increased neutralisation caustic/potassium hydroxide consumption. Carry-under of hydrocarbons to the settler impacts I/O ratio and chemistry, leading to disrupted conditions and suboptimal yields.
