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.
Extend heat exchanger lifecycle with hyper-duplex stainless steel
Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.
Improve the operation of fired heaters
Fired heaters or “process furnaces” are used extensively by the refining and petrochemical industries. These heat transfer units generate the much needed process energy through the combustio..
Determine the design metal temperature for a secondary reformer
An air-burning system should be designed so that there is no maintenance required between scheduled shutdowns every two years. To achieve this, a metal temperature study should be carried out for the design of the pressure parts and for the refractory design.
Optimize online monitoring of base oil
Latter-model vehicles and new automotive engine designs now require higher-quality lubrication oils, such as Groups II and III. Demand for Group II/III base oils is increasing. To capitalize on the gr..
Shale oil characterization optimizes refining process
The abundance of shale oils is an unexpected gift for US refiners. These new crude oils have different characteristics from conventional oils that will affect refining processes and the operation of p..
Update on the catalytic cracking process and standpipes—Part 1
The fluid catalytic cracking (FCC) process is a well-established technology used by complex refineries. It is a key profit center, as the FCC unit (FCCU) has the flexibility to produce transportation ..
HP Editorial Comment: Downstream has good news for 2015
The outlook is optimistic for downstream companies. Independent refiners are positive on present and future demand for transportation fuels.
HP Boxscore Construction Analysis: How low oil prices are affecting new project announcements
Beginning in July 2014, the world began to witness a widespread fall in crude oil prices. With the decrease in global crude oil prices, what has this meant for new project announcements in the downstream sector?
HP Global: Latin America’s refinery product demand is decelerating
The trajectory of refined product balances in Latin America and the Caribbean is changing. With demand growth slowing and throughput expected to rise by 2020, the region’s combined deficits for p..
