What is a demulsifier?

It’s a substance that dissolves emulsions (that is, to separate the two phases). Whether an emulsion is water-in-oil or oil-in-water determines the sort of demulsifier that should be used. Demulsifiers are used to treat generated hydrocarbons and in the chemical analysis of oil and synthetic muds. Why are demulsifiers important? They are frequently employed in […]

Pour Point Depressants – keeping the oil flowing

Charles Wemyss, Litre Meter’s CEO and pour point expert explains why measuring pour point depressants (PPD) can keep oil flowing. What is Pour Point? First off, what is pour point? It’s the lowest temperature at which liquid is still pourable. There is an ASTM test (D-97) which defines the pour point as when the oil […]

What’s the best chemical injection flow meter?

Litre Meter VFF rotary piston positive displacement flowmeters have proven to be the foremost solution for chemical injection flow metering applications. They are able to handle the wide range of flows at pressures from a few bar up to 10,000 and 20,000 psi (690, 1,380 bar) and higher. The FlowPod instrument has been developed after feedback […]

Chemical Injection Flow Meters

Chemical injection is the process designed to assist in the production of oil where various chemicals are injected into the crude oil to provide a degree of protection.  For example; a scale inhibitor will prevent the build-up of scale on the pipes and fittings used to transport the oil on its journey to the refinery.  […]

Flow meters for Sodium Hypochlorite – Hazardous Area, too

Chemical Injection process: Sodium hypochlorite We look at the chemical injection process of injecting sodium hypochlorite into sea water, in a variety of settings. Sodium hypochlorite is a green/yellow liquid with the characteristic smell of chlorine. It was first used as a bleaching agent and was then discovered to be effective in controlling wound infections. Subsequently, it is […]
