Improve process analyzer performance in petrochemical operations by delivering stable flow and pressure where measurement accuracy, repeatability, and system reliability depend on tight control. Integrated proportional control, multivariate data collection, and 30 ms proportional valve response help engineers fine tune sample injection, carrier gas delivery, and backpressure control for more consistent measurements and fewer manual adjustments in the field. Alicat^® offers certified options for Class I Division 2 applications. For the most demanding environments, intrinsically safe instruments that meet the highest hazardous zone requirements in North America, Europe, and internationally, including Class I Division 1, ATEX Zone 0, and IECEx.

Flow and pressure instrument applications in oil & gas

Stabilize analyzer sampling in ethylene steam cracking

In ethylene steam cracking, stable sample conditioning helps keep gas chromatographs, oxygen analyzers, and Wobbe index analyzers delivering reliable data for furnace optimization, coking control, and safe operation. In this application, see how Alicat flow and pressure instruments simplify analyzer loops by combining measurement and control. Operators can maintain backpressure, stabilize split ratios, and reduce drift across multiple sampling points in hazardous areas.

Pressure vessels support critical storage, separation, and process functions across oil and gas operations, where poor pressure control can create safety risks, inefficiency, and downstream instability. This application shows how Alicat pressure controllers give engineers more stable, proportional control than traditional pneumatic systems. By helping maintain vessel pressure, IS‑Pro™ can improve downstream performance, with one simple installation in a Class I, Division 1 environment.
