People-Focused Work Areas Often Carry Greater Risk 

Oil and gas operations spread contaminants across a wide site, but the real exposure risk concentrates wherever workers actually spend time.

Fugitive emissions leak continuously from valves, seals, flanges, and pump packing throughout a facility, releasing a mix of VOCs including benzene, toluene, and other BTEX compounds. Sour gas streams and certain crude sources bring hydrogen sulfide into the mix, which is dangerous even at low concentrations. Loading, storage tanks, and process units add their own VOC releases during normal operation. And because outdoor air across the site carries these contaminants, the control rooms, offices, and other occupied buildings on-site need their intake air treated, or contaminants get pulled straight in with the ventilation.

Where Exposure Risk Actually Sits

  • Control rooms or occupied buildings pull in outside air without gas-phase treatment

  • Fugitive emission surveys have flagged leaks near occupied areas

  • Your site processes sour crude or sour gas streams

  • Staff have reported odor or irritation near tanks, units, or loading areas

  • A new control building or occupied structure is being sited near process equipment

  • Air intake for HVAC systems sits close to potential emission sources

Protecting Occupied Buildings From What's in the Outside Air

Electrocorp's gas-phase filtration is built to treat incoming air for control rooms, offices, and other occupied buildings on refinery and well sites, pulling out benzene and other VOCs along with hydrogen sulfide before they enter occupied space. This matters most where a building's air intake sits near process units, tanks, or loading areas that release fugitive emissions. Systems can be integrated into a building's air intake or added as a standalone unit for spaces without existing gas-phase treatment.

Frequently asked questions

Why does a control room need its own air treatment if it's a sealed building?

Even sealed buildings pull in outside air for ventilation, and if that air isn't treated, it carries in whatever's in the outdoor air nearby, including benzene and hydrogen sulfide from fugitive emissions.

Is hydrogen sulfide dangerous even at low concentrations?

Yes. Hydrogen sulfide is toxic at low levels and can cause respiratory issues at higher exposure, which is why sour gas and sour crude operations treat it as a serious ongoing hazard, not just an odor issue.

Can filtration replace personal gas monitors for site workers?

No. Personal and area gas detection remains essential for workers moving through the site. Building air filtration is a separate layer that protects people once they're inside an occupied structure.

Do fugitive emissions really add up to a measurable exposure risk?

Yes. Individual leaks from valves and seals are often small, but across a large facility they add up, which is why fugitive emission surveys and leak detection programs exist in the first place.

How do I know if our control room's intake air needs treatment?

An air quality survey near the intake location, checking for VOCs and hydrogen sulfide, tells you whether the incoming air needs gas-phase filtration before it reaches occupied space.
