What is acid gas treatment?
Acid gas treatment and removal technologies separate sour gases—highly corrosive CO 2 and often deadly H 2 S acid gases—from saleable natural gas streams in a process known as gas sweetening. Once removed, the CO 2 and H 2 S are usually vented in low concentrations, flared, and then reinjected or otherwise properly disposed of. Larger concentrations of CO 2 are recovered and repurposed for enhanced oil recovery applications.

What is sour gas?
Sour gas is natural gas that contains hydrogen sulfide (H 2 S). A natural gas is “sour” when the H 2 S content of the gas mixture exceeds the limit imposed by the purchaser of the gas, usually a transmission company or the end user. Generally, the limit for H 2 S content is one grain of H2S per 100 scf of sales gas.

What are the requirements for sales gas?
Specifications for sales gas describe the required physical properties of the gas such that it can be transported under high pressure through long distance pipelines at ground temperature without forming liquids, which could cause corrosion, hydrates , or liquid slugs into downstream equipment. Limits on the content of certain nonhydrocarbon compounds are also specified. While the specific limits for each item might vary among transmission companies or customers, the overall specifications for sales gas generally include:
Can natural gas contain CO2?
Virtually all sour natural gases also contain CO 2, but the converse is not true: many natural gas mixtures can contain CO 2 without any H 2 S. CO 2 and H 2 S are called “acid gases,” or collectively “acid gas,” as both gases are slightly soluble in water and form a mildly acidic solution. Most regenerative processes used for H 2 S removal from natural gas also remove CO 2. If a natural gas contains amounts of CO2 in excess of the sales gas limit, but no H 2 S, there are specific processes available for CO 2 removal.

What are polysulfide ions?
Polysulfide ions can also manage the impact of cyanide ions in the scrubbing agent solvent to control the negative effects of cyanide in acid gas treatment processes. The introduction of elemental sulfur to generate polysulfide ions can prevent hydrogen embrittlement in the upper parts of a regeneration tower. The HCN amine salt partially decomposes in the upper section of the regenerator to give HCN, which produces H+ ions. H + ions penetrate the metal structure and are converted to a larger H 2 molecule, causing a tremendous force inside the metal that causes it to split. The polysulfide ions, however, can be used to convert cyanide ions to the more benign thiocyanate ions and a polysulfide ion with one less sulfur atom [ 39 ]:
What is CDR in methanol?
QAFAC methanol plant with an example of process integration, where CO 2 from the flue gas from the reformer is captured and fed to the methanol reactor, CDR refers to Carbon Dioxide Recovery [ 11 ].
How does flue gas react with amine?
The flue gas is contacted with the absorption liquid in a contactor, in which the CO 2 is absorbed into the liquid and reacts with the amine. Subsequent heating of the liquid absorbent releases CO 2. The chemical reaction is selective, in that only acid gases react, whereas others do not.
How is crude oil treated?
Crude oil and natural gas are desulfurized in oil and gas refineries using hydro-, oxidative, adsorptive and bio-catalytic desulfurization and amine extraction processes. These processes generate acid gas waste streams with varying compositions that are further treated to recover elemental sulfur/and or thermal energy. Compared to other process types, such as H 2S scavengers, liquid redox, Selectox and biological processes, the Claus process is most mature technology for the recovery of energy and elemental sulfur. Most often a combination of acid gas treatment processes is required to achieve very high conversion efficiency of four nines (nearly 99.99%). However, desired sulfur recovery capacity is the most important criterion in the selection of most cost effective acid gas treatment technology. It is recommended to deploy scavengers for systems when the sulfur recovery capacity desired is less than 0.0023 kg/s. For sulfur recovery capacity greater than 0.24 kg/s, Selectox and recycled Selectox processes or amine gas sweetening units in conjunction with catalytic Claus type reactors and tail-gas systems are recommended. For anything in between, liquid redox or direct oxidation processes are considered.
How is crude oil desulfurized?
Crude oil and natural gas are desulfurized in oil and gas refineries using hydro-, oxidative, adsorptive and bio-catalytic desulfurization and amine extraction processes. These processes generate acid gas waste streams with varying compositions that are further treated to recover elemental sulfur/and or thermal energy.
How many chapters are there in PCC?

What are the impurities in a Claus reactor?
The roles of different impurities (CO 2, CH 4, NH 3, C 3 H 8 and BTX) in sulfur recovery chemistry in the thermal stage of Claus reactors have been discussed. These impurities significantly alter the chemical kinetics of H 2 S combustion, reducing process efficiency and performance and increasing operational cost. The formation of sulfurous compounds (COS and CS 2) with different compositions of acid gas under high Claus reactor condition was also presented, and reactor conditions that promote destruction of acid gas and associated impurities, as well as mitigate/promote COS and CS 2 production with respect to different compositions of acid gas, were evaluated. Some of the important reaction pathways for acid gas treatment in Claus reactors were also provided.
How to know if a lubricant agent is working?
Lab testing for lubricity - the only way to know, with certainty, if a lubricity agent was really doing what it's supposed to, would be to submit a treat fuel sample to a lab for an ASTM lubricity test. The HFRR would tell you with certainty if the additive was improving fuel lubricity or not.
Why do you need fuel detergents?

How do you know if something works?
If you can know for sure if something works, you can be a lot more confident in any decision you might make regarding it . In order to know if something "works", you have to know what constitutes success. You have to know what you're looking for.
Why is knowing what to look for important?
Again, knowing what to look for is essential to reaching the right conclusions and making the right decision.
Does fuel lubrication affect fuel pump wear?
Decrease in injector and fuel pump wear - if you knew that fuel lubricity is directly related to wear in injectors and fuel pumps (which it is), then you would want to pay attention over time to the rates at which you had to replace those items.
Does lubricant improve mileage?
Fuel mileage improvement - lubricity doesn't have anything meaningful to do with mileage. So someone who used a lubricity additive and then judged it by tracking their rate of fuel use, that wouldn't tell them any meaningful. And if they made a judgement, for or against, based on some MPG improvement or lack thereof, they'd be making conclusions based on faulty assumptions and they wouldn't actually know what they think they know.
