New design features enhance separation performance

The Shell Schoepentoeter™ is a vane-type inlet device for feeding high momentum gas-liquid mixtures into separators or distillation columns. The Schoepentoeter has two main functions: separating the liquid from the vapor and evenly distributing the vapor in the gas compartment of the vessel. While Schoepentoeters have been recognized as the primary choice of radial inlet device in many separator vessels, performance in distillation columns has been challenged by proponents ...

RVP in process: ensure safety, comply with specifications, optimize profits

Pipeline operators, offshore platforms, terminals, fuel depots or oil tankers detect the vapor pressure, before transporting crude oil or other petrochemical products such as Gasoline or LPG for subsequent processing. It is absolutely necessary to know the vapor pressure of the transported substance to prevent costly damage done to the transportation or storage system.   Apart from the costs a failure might cause, environmental regulations limit maximum vapor pressure ...

Safeguard packed column efficiency with proper liquid distribution

Initial liquid distribution directly affects the efficiency of structured and random packing beds. As such, some form of flow test should be conducted to validate distributor performance prior to column startup. Steady state water flow testing is the most common method of testing distributors. It can be conducted in the shop or in the field to verify the design, manufacture and installation. Three Common Types of Liquid Distributor Flow Tests • Liquid Range Test with ...

Improved technology for carbon capture & storage saves capital cost

Total man-made carbon dioxide (CO2) emissions in the world today amount to approximately 30 Gigatons per year, with fossil fuel-based power stations contributing in excess of 30% of this total. Carbon Capture is an energy intensive process, buy Sulzer’s specialized technology allows the operator to minimize capital expenditures and at the same time, minimize power output losses that can result from poor designs. High Efficiency Mass Transfer Products Reduce Capital Costs ...

Opportunity or Annoyance?

Price differentials between conventional and opportunity crudes compel refiners to process increasing percentages of lower valued opportunity crude. However, as many refiners have learned the hard way, opportunity crudes are tied to unique processing challenges. Furthermore, existing crude unit configurations may limit high profit opportunity crude to a disappointingly small proportion of the total unit blend. Processing a changing slate of opportunity crudes of varying compositions ...

Tracerco Diagnostics™ Distribution and Residence Time Studies

What type of studies does Tracerco provide for reactors and what do they reveal? A Tracerco Diagnostics™ Distribution or Residence Time study provides crucial information to measure reactor performance. They provide valuable information about the residence time and distribution of solids, vapour or liquid at specific operational conditions. Results from the study can assist plant personnel to accurately diagnose integrity problems with internals and determine uniformity of distribution ...

Optimise crude processing with the Profiler™

The Challenge: Refiners aim to optimise feedstock blends to improve margins, but variability can bring significant operational challenges during the process. One critical need is the efficient removal of solids, salts and water from crude feedstock. It is essential that washing of the crude is effective at removing high levels of these, and the oilcan be efficiently separated prior to crude distillation. Efficient separation needs accurate and reliable interface control to manage ...

ISOMALK - moving forward ahead of global trends

Changes in trends in the world and regional markets of motor fuels are sometimes completely unpredictable. A few years ago, it seemed that the development of massive «dieselization» trend, so dominant in the EU, would lead to a drop in demand for gasoline. It seemed that diesel engines solved both the problem of reducing CO2 emissions and increasing efficiency, making the diesel fuels the trade-off solution that would allow the world's motor vehicle to survive quite well ...

Interface measurement in desalters

Interface measurements in desalters are often regarded as not being very critical, even though every drop of oil, to be refined, passes through the desalter. As refineries try to maximize their margins, so-called opportunity crudes are often used. These crude oils generally contain increased levels of sulphur, oil sands, bitumen, heavy oils and oils with high TAN. This can lead to problems with the proper operation of the desalter. In addition, refineries are increasingly confronted ...

Top of Side Entry? Your Choice

The capacity of LNG plants has significantly increased over the years and geopolitical conflicts will likely push the market to new Liquefaction facilities, carriers, LNG terminals and regasification units. Valves are a critical component at each stage. Valve performance and reliability are vital to the whole process. The unique design, high quality manufacturing and material selection of Zwick Armaturen makes them ideal for LNG installations and other Cryogenic applications.

Structured grid packing

Structured grid packings have traditionally been used for high severity services. Grids have a high open area, relatively low surface area, and a robust construction to withstand process upsets and to resist fouling. There are two main types of grids, categorized by structure - conventional grid and corrugated, high-efficiency grid. Developed first, conventional grids have a structure made from vertical members and angled flaps. The simple construct is fouling resistant, but has ...
