PURASPEC CLEAR Chloride guards

Chlorides in a refinery. Where does it come from? Chlorides are introduced into the refinery flowsheet in several ways. Some crude sources can bring both inorganic and organic chloride content. Desalter processes and chemical additives are used to remove chlorides and prevent corrosion and fouling caused by these chlorides. The other major source is from the Catalytic Reforming Unit (CRU). This unit upgrades straight run naphtha value for use in the gasoline pool or as petrochemical ...

THIOLEX™ caustic extraction of acid gas

THIOLEX™ technology was rst licensed in 1980 and to date Merichem has granted 224 unit operating licenses world-wide. The non-dispersive FIBER FILM® Contactor achieves reduced capital expenditure and less plant space requirements compared to most treating alternatives, making THIOLEX™ the technology-of-choice. Each treating system is custom-designed to meet customer requirements, then engineered and fabricated to the customer's specifications. Whether your ...

ThruPipe™ flaring piping systems

ThruPipe™ Scan. What does it do? A ThruPipe™ scan of a pipe is a non invasive method to examine the contents of a pipe and identify any localised fouling and blockage in the line. The power of the ThruPipe™ technology is that the scanning is done online, so real time information is obtained about how the flow through the pipe is performing at that instant. The scan “sees through” the pipe wall so a determination of what is happening inside without the need to shut down ...

Tracerco PhaseFinder™

What type of services does Tracerco provide for desalters and what does it reveal? A Tracerco PhaseFinder™ scan of a desalter measures interface levels through the vessel wall between liquid and solids, or between two different types of liquids. A PhaseFinder™ scan of desalter vessels will yield a lot of information about where the various layers of material are located, and the quality of interface between oil and water. A tracer study can be used to measure the oil and ...

Tray designs for extreme fouling applications

Today refiners experience a lot of problems with processing of opportunity or heavy crudes. Such crudes have very high sulfur content and require the addition of amine scavengers before desalting. These amines decompose in the heater and create ammonium chlorides in the presence of water in the top of the crude tower. Dissolved salts start to precipitate and crystallize when the solution becomes saturated and water is vaporized. Such fouling starts to grow below and above trays ...

Why do many crude/vacuum units perform poorly?

In many cases it’s because the original design was based more on virtual than actual reality. There is no question: computer simulations have a key role to play but it’s equally true that process design needs to be based on what works in the field and not on the ideals of the process simulator. Nor should the designer simply base the equipment selection on vendor-stated performance. The design engineer needs to have actual refinery process engineering experience, not ...

Xtend by XRG - A better technology for heat transfer

Fired Heater Fouling Costs Millions. A typical 100,000 barrel per day refinery loses $3-7 million annually because of fouling in fired heaters. Fouling overheats tubes, increases firing rate, reduces yields, and causes lost onstream days. Shutting down a crude, vacuum, or coker heater is extremely costly both in labor and throughput. To combat these issues, XRG Technologies developed Xtend - a tube-insert to reduce fouling and increase heat transfer. Xtend - A Better Technology ...
