Acid Gas Removal
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
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
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
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.
Innovations
Power generation and heating, ventilation and air conditioning (HVAC) specialty rental company, Aggreko Plc., and sulfuric acid alkylation technology licensor, DuPont, have collaborated to provide Aggreko temperature control, including chiller systems, to STRATCO sulfuric acid alkylation customers.
Boost capacity of SRUs with mixing devices for oxygen enrichment
The requirement for additional sulfur recovery unit capacity in a refinery may stem from hydroprocessing operations; a refinery expansion project; a shift from lighter to heavier, sourer crudes to improve margins; or the need to remove extra sulfur content to meet tighter environmental regulations.
Improve refinery flexibility and responsiveness
The hydrocarbon processing industry (HPI) has changed significantly with an abundance of available discounted crude oils, a rise in markets served beyond the traditional local or regional demands, and a renewed focus on being both competitive and profitable while complying with ever-changing regulations.
Improve relief-device sizing under supercritical conditions
Properly sized relief devices under supercritical conditions are vital to processing natural gas and gas condensates into olefins. These processes operate near the critical locus of the process gases ..
Bolivia expands petrochemical capability with Bulo Bulo ammonia complex
The Bulo Bulo ammonia-urea facility will be Bolivia’s first petrochemical venture. This new facility is expected to produce sufficient urea/ammonia supplies for domestic demand and will provide surplus product for export.
How caustic stress leads to failures of incinerator caustic spray nozzles
Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.
