Chemical

Agricultural & BioChemicals

Fertilizers, fungicides, herbicides, pesticides, and fumigants are all used in the agricultural process. Their production and application can use pressure switches in hydraulic application and environmental regulation to ensure safety. Their storage can often best be monitored with a liquid level. Whitman switches are incredibly useful for these applications.

Petrochemical

Different from regular Oil and Gas, petrochemicals are a result of a complex refinement process and used in a variety of non-energy related applications. Oil refineries produce olefins and aromatics by fluid catalytic cracking (FCC) of petroleum fractions. The modern FCC units are all continuous processes which operate 24 hours a day for as long as 3 to 5 years between scheduled shutdowns for routine maintenance. Whitman temperature switches, pressure gauges, and pressure switches are all useful in this application.
