Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Use modeling to evaluate processing solutions for heavy oils
To optimize processing and reduce design and operating costs, refiners should consider using accurate simulation models that are specifically tailored for heavy crudes.
Catalyst systems offer flexibility for hydroprocessing applications
Refinersa re strongly motivated to evaluate and select premier catalyst systems for the production of both diesel products from their hydrocracking and diesel treating units.
Improved oxidation process increases sulfur recovery with Claus unit
Since its development in 1936, the “modified Claus” technology has been the preferred process used by refineries and gas processing plants for the recovery of sulfur from acid-gas streams. M..
Update: Russia’s capacity and modernization program
Since 2008, Russian regulations regarding the crude oil and refining industry have changed substantially. At present, Russia has 22 large refineries, each with an individual throughput capacity exceed..
Novel use of sulfiding agent prevents refinery shutdown
When an insufficient supply of acid gas threatened to shut down operations at a US refinery, quick thinking, along with the novel use of a sulfiding agent and a strong supply chain made all the difference.
Consider accurate feed characterization with improved simulation methods
Assay definition is crucial for accurate process simulations. The performance of process simulators depends on the feed definition to the processing unit. Modern analytical laboratories can offer comp..
Optimize slop-wax bed height in the vacuum unit
The vacuum distillation (VD) unit in the petroleum refinery separates the heavier fraction of crude oil from the atmospheric distillation unit (ADU) into light vacuum gasoil (LVGO) and heavy VGO (HVGO..
HP Boxscore Construction Analysis: Brazil plans major refinery expansions
Brazil is the largest producer of liquid fuels in South America. However, the country still lacks the installed refining capacity to meet domestic demand for transportation fuels. For this reason, Brazil has a number of refining projects planned and underway.
HP Viewpoint: Renewables from the refiners’ viewpoint
Recently, I had the opportunity to testify before the US Senate Committee on Energy and Natural Resources, representing our company and our industry that employs approximately 108,000 American workers..
