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 ...

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 ...

Vapor pressure testing for petroleum, LPG, crude oil and Chemicals

Vapor pressure is an important physical property of volatile liquids especially of spark-ignition engine fuels. It provides an indication of how a fuel will perform under different operating conditions. For example, vapor pressure is a factor in determining, whether a fuel will cause vapor locks at high ambient temperature or at high altitude, or will provide easy starting at low ambient temperatures. Petroleum product specifications are regulated by various governmental agencies. ...

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 ...

Why produce diesel from the vacuum unit?

Look ahead five years. The economy is likely to keep tightening and the rush to control pollution will inevitably be accompanied by demands for greater energy conservation. Consequence? A growing market for diesel which yields more energy per unit volume. Yet many continue to believe that producing diesel from the vacuum unit is poor design—that it should be produced only from the atmospheric column. Hence many refiners feed 20-30% diesel boiling range material to their ...
