Acid Gas Removal

Refining: Alkylation—What’s a refiner to do?

Pawloski, J., Veolia Water Americas

Within the refining industry, gasoline production and alkylation capacity are running at near all-time highs.

Case histories of amine plant equipment corrosion problems–Part 1

Daughtry, J., Teletzke, E., INEOS Oxide GAS/ SPEC Technology Group

Lost production from corrosion costs the oil and gas industry more than $1 B/yr.1

Optimizing the dehydration process with advanced process simulation

Dyment, J., Aspen Technology

In the operation of natural gas pipelines, a blockage or leak can cause expensive production losses, damage equipment and pose safety hazards.

Heavy crude oil processing design and reliability

Martin, G., Liu, Z., Wang, S., GTC Technology US LLC

Revamping refineries to process heavier crude slates goes well beyond the requirements to meet equipment performance dictated by a shift in the quantity of lighter product yields to heavier products.

Process safety incidents involving simultaneous operations

Baybutt, P., Primatech, Inc.

Some process safety incidents occur as the result of simultaneous or sequential occurrences of operations or activities that interfere or clash with each other.

Turn to open-path laser detectors for HF gas safety

Dean, K., MSA Senscient

Process engineers at a refinery in one of the Rocky Mountain states were concerned about detecting the potential accidental release of hydrogen fluoride (HF) gas at their plant as part of a recent series of upgrades to the facility.

HF alkylation conversion is finally within reach—Part 1

Because of its clean-fuel properties (paraffinic, high octane, low vapor pressure and very low sulfur), alkylate is considered one of the most desired components in the gasoline pool.

Installation of liquid sulfur degassing processes in existing SRUs

Van Grinsven, R., Van Son, M., Jacobs Comprimo Sulfur Solutions

Over the last 35 yr, more companies worldwide have installed liquid sulfur degassing processes in their sulfur recovery units (SRUs) to minimize the dangers of the release of hydrogen sulfide from the produced elemental sulfur.

Put acid gas hydrocarbons in their place with staged regeneration

Bela, F., WorleyParsons

Common organic contaminants of Claus sulfur recovery unit (SRU) acid gas (AG) feed include: heavy hydrocarbons, in general; benzene, toluene, ethylbenzene and xylene (BTEX), in particular; and methanol (CH3OH).

Handling mercaptans in gas processing plants

Mokhatab, S., Consultant; Northrop, P. S., ExxonMobil Upstream Research Co.

With the continued development of sour gas fields around the world, the removal of mercaptans from gaseous and liquid hydrocarbon streams is becoming a challenge for today’s gas processing plants.
