Oil Gas and Petrochemical Industry

Alicat in Oil, Gas & Petrochem - why it fits, what hurdles it overcomes

Typical hurdles in Oil, Gas & Petrochem

Operation in hazardous zones, keeping analyzers and air‑monitoring skids stable in harsh outdoor environments, verifying operation quickly with less human intervention, and capturing rich diagnostics for maintenance and compliance. Alicat’s intrinsically safe portfolio is engineered precisely for this context.

IS Max™ & IS Pro™ (intrinsically safe) at a glance

  • Certification: ATEX / IECEx Zone 0 intrinsically safe (II 1G Ex ia IIC T4 Ga), with UKCA/CE, and NRTL/IECEx compliance—designed for Class I, Div 1 / Zone 0 environments where flammable gas may be continuously present.
  • Enclosure & longevity: IP66 case rated for dust tight, high impact, and water jet exposure—ideal for outdoor analyzer shelters and exposed monitoring skids.
  • Unified control & metering: IS Max can control on pressure while simultaneously measuring flow — simplifying GC sample handling and analyzer front ends (fewer components, simpler wiring/P&IDs).
  • Hazard area communications & data: Native Modbus / ASCII serial plus analog I/O deliver multivariate reporting (flow, pressure [absolute/gauge], temperature, barometric pressure, totals, alarms) for 24/7 remote verification, scripting and data logging—without opening the enclosure.
  • Analyzer & environmental monitoring benefits: Rapid, repeatable control improves gas calibration, blending, vent gas control, TDLA/FTIR/NDIR/O₂/H₂ analyzers and CEMS sampling—faster stabilization, fewer truck rolls, and better records for audits.
  • Valve usage insight for maintenance: Digital reporting includes setpoint/status and operating cycles, enabling preventive maintenance on valves and components before failure.
Alicat intrinsically safe meters
  • Low ΔP options for leak checks: Where quick integrity checks are needed, low pressure drop IS flow meters/controllers (e.g., ISMCW) improve sensitivity and speed for leak-testing and purge verification.

Quick wins in the field

  • Reduced human intervention: Multivariate telemetry + scriptable batching/totalizers = faster remote verification that skids are in spec, cutting site time.
  • Better control with fewer devices: Use an IS Max to control pressure while measuring flow — one device, two jobs; fewer fittings, lower leak risk, simpler hazardous area compliance.

Jordan Valve + LowFlow (Richards Industrials) — reliable regulation & precision control

Jordan Valve's range of self-operated and air-loaded pressure and temperature regulators are trusted throughout the oil, gas, and petrochemical sectors for their robust construction, consistent performance, and ease of maintenance. Their unique sliding gate seat technology minimises friction and wear, resulting in longer service life, tighter shutoff, and reduced maintenance costs compared to conventional globe valves. This makes them ideal for demanding applications such as fuel gas trains, steam tracing, pressure reduction, and back pressure control in both upstream and downstream operations.

For applications requiring precise control at very low flow rates, the LowFlow 708 series excels. With Cv values down to 1e-5 and a wide range of body and trim materials, LowFlow valves are perfect for pilot plants, analyser sample conditioning, catalyst dosing, and micro-reactor feeds. Their compact design, high turndown, and rapid response ensure stable process conditions even when handling aggressive or high-purity media.

Both Jordan and LowFlow valves are available with a variety of end connections, actuation options, and certifications to meet the stringent requirements of hazardous area installations and critical process environments. Our team can help you select and size the right valve for your specific application, ensuring reliable, efficient, and safe operation across your facility.

Jordan regulators used widely in OGP

These deliver robust, mechanical control where simplicity, quick response and plant class metallurgy are essential.

For micro/critical duties, LowFlow 708 brings fractional flow control with Cv down to 1e 5 and up to 4.0, multiple end connections, high temperature packing options, and fast trim changes—ideal for pilot plants, analyzer sample conditioning, catalyst/reactor dosing and hydrogen/natural gas micro feeds.

Benefits to highlight

  • Plant grade simplicity: Self operated and air loaded regulators reduce complexity and are field serviceable—good for remote sites.
  • Precision at low flows: LowFlow 708’s guided trim and rolling diaphragm deliver stable, high resolution control where small disturbances change results.

Equilibar® back pressure control — including the IC Industrial Collection

Equilibar's dome loaded, multi orifice architecture delivers frictionless, hysteresis free control across challenging regimes—gases, liquids, and mixed phases, from micro flows to high flows—ideal for pilot plants, reactor back pressure, tank blanketing, vapor/liquid separators, and flare/vent control.

Industrial high flow options (line sizes & Cv)

  • IC Industrial Collection (ASME B16.34 Class 150/300) — 1.5", 2", 3" sizes in CF3M/1.4409 stainless steel as standard; NPT, ANSI RF flanges and tri clamp, with Hastelloy/nickel alloy options. Built as plant class replacements where higher flow and robust compliance are needed.
  • BD Series — industrial service up to 4″ port sizes for larger headers and abatement duties.

Which form factor when?

IC offers a heavy duty, ASME compliant package for plant utilities and high flow processes; BD provides larger 1½″–4″ sizes for very high flows. Both employ Equilibar’s dome loaded multi orifice technology for precise, stable control across wide turndown and changing phases. Our application engineers can help choose the best fit.
