Is Sour water flammable?
This material is generally not flammable; however, it may contain hydrogen sulfide which is extremely flammable, or crude oil, condensate or natural gas, all of which are flammable.
What is the density of sour water?
Upper Flammability Limit: Not available. Vapor Pressure: Not available. Vapor Density: Not available. Relative Density: 1 to 1.2 (Water = 1) Solubilities: Not available.
What is sour crude and its hazards?
Crude oil (sour) is extremely flammable and can cause eye, skin, gastrointestinal, and respiratory irritation. Inhalation may cause dizziness, nausea, or headache. More serious health effects can occur if crude oil is inhaled or swallowed. Crude oil (sour) may contain variable amounts of benzene and N-Hexane.
Is produced water flammable?
This material is nonflammable. It may contain crude oil, condensate, or natural gas, all of which are flammable. This material should not present a serious problem under anticipated conditions. Contain spill and cleanup as soon as possible.
At what level is H2S flammable?
The explosive range of hydrogen sulfide in air is 4.5 to 45.5 percent. This range is much higher than the PEL.
What is sour water?
Sour Water is the wastewater that is produced from atmospheric and vacuum crude columns at refineries. Hydrogen sulfide and ammonia are typical components in sour water that need to be removed before the water can be reused elsewhere in the plant.
What is considered sour water?
Sour water is produced in refinery process units, as water is used for steam stripping and quenching. Sour water is contaminated mostly with ammonia (NH3) and hydrogen sulfide (H2S), which must be removed before the water is recycled back into the process.
How much H2S are in sour crude?
Most rail, truck and pipeline facilities are now requiring low H2S content in crude oil and condensate. Some institutions and companies have implemented policies to turn away crude oil with more than 5 ppm H2S content.
What’s the difference between sweet crude and sour crude?
Crude oil is defined as “sour” if its sulfur content exceeds 0.5%, or if it does not meet the required thresholds for hydrogen sulfide and carbon dioxide levels. Sweet crude, on the other hand, is defined by the New York Mercantile Exchange (NYMEX) as petroleum with sulfur levels below 0.42%.
Is oily water flammable?
The flammability of a crude oil sample containing water depends on the concentration of water in the mixture. Reasonably, a mixture having high water content is expected to not be flammable, but there is no clear cut value or range to support this claim so far.
What is the maximum safe exposure to hydrogen sulfide?
OSHA: The legal airborne permissible exposure limit (PEL) is 20 ppm not to be exceeded at any time, and 50 ppm as a maximum peak, not to be exceeded during any 10-minute work period. NIOSH: The recommended airborne exposure limit (REL) is 10 ppm, which should not be exceeded during any 10-minute work period.
What is the flash point of H2S?
Hydrogen sulfide
| Names | |
|---|---|
| Flash point | −82.4 °C (−116.3 °F; 190.8 K) |
| Autoignition temperature | 232 °C (450 °F; 505 K) |
| Explosive limits | 4.3–46% |
| Lethal dose or concentration (LD, LC): |
How do you remove H2S from sour water?
It is a colorless, flammable, and corrosive gas, being extremely toxic to living organisms. In petroleum and gas refineries, H2S is typically removed from sour water by steam stripping in packed or tray columns.
What is sour water treatment?
Sour water stripping is used to remove ammonia (NH3) and hydrogen sulfide (H2S) from sour water streams coming from many unit operations to condition it for discharge or reuse within the refinery.
What is sour water used for?
What’S the difference between sweet crude and sour crude?
