The majority of dividing wall column (DWC) applications in the refining industry consist of standalone columns, whether a retrofit or a grassroots column.
In the conventional development approach, a multi-stage process begins in the laboratory, moves to the pilot plant, and ends at the commercial unit, often before any financial benefits are realized.
In the petroleum refining industry, pH measurement and adjustment are extremely important.
This case study details the production of tetrahydrofuran (THF), with a purity of 99.96 wt% and water moisture of less than 200 parts per million (ppm).
Although the refining industry is expected to add more than 7 MMbpd of new distillation capacity by the early 2020s, the global refining industry will witness a boost in secondary processing capacity, as well.
According to multiple industry reports, crude oil consumption will continue to increase over the short term.
The cost-effective revamp experiences of carbon dioxide (CO2) removal systems in three different ammonia plants, and the resulting attractive payback of just a few months are detailed here.
Typically, opportunity crudes require more rigorous desalting to yield high-quality products due to high levels of naphthenic acids, basic sediment and water (BS&W) and filterable solids, among others.
In the past few decades, new technologies, including both carbon rejection methods and catalytic conversion methods, have emerged.
The production of liquefied natural gas (LNG) requires a number of stages to effectively purify the feed gas. These stages are essential to maintain continuous operation and to meet product specifications. Liquid and solid contamination issues are common in many feed gas purification operations and can cause severe problems with equipment fouling, leading to additional expenses in maintenance and equipment repair, reduced production capacity and even unscheduled shutdowns.
