Measuring the level of tower bottoms

The level measurement in the bottom of any distillation column is a critical measurement task in refineries. Tower internals damage due to the failure of level control technologies for residual bottoms is one of the most common issues in refineries. However, this is not the only way that reliable bottoms level measurements can save costs and increase efficiency in the refining process. In the atmospheric distillation process as well as in vacuum distillation, crude oil is separated ...

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 ...

LO-CAT® process for waste water treatment plants

In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOX emissions from the on-site combustion of the gas could be kept within acceptable regulatory limits, allowing the gas to be burned on-site to generate steam for ...

FracSENS LB 6770 Density Meter

The FracSENS LB 6770 nuclear density meter can connect directly to the control system. Without the transmitter unit, the outputted count rate can be used in the control system to calculate PPA, PPG, or SGU in both low and high pressure applications. The new scintillation technology ensures high sensitivity and allows drastic reduction of source activity compared to conventional ion chamber detectors. A maximum of 20 mCi has proven sufficinet for traditional fracturing applications. With ...

Caustic tower revamp

A customer contacted Sulzer to increase capacity while improving the CO2 removal in the existing CO2 absorption column of their ethylene plant. This was the third revamp for this particular column and continued improvements can be hard to find. A proper caustic tower design requires a proper understanding of CO2 absorption with caustic. CO2 + 2NaOH Na2CO3 + H2O Sulzer replaced the conventional random packing with NeXRing and modified the operating parameters to match the ...

Is pinch enough?

Back in the late 1970’s and early 1980’s when fuel gas prices were high, energy utilization assumed major importance. A new method of calculating heat exchanger networks was developed. It was called Pinch Technology. Today pinch has been rediscovered by engineers who have access to fast computer simulation models. But as occurs with any older method that is rediscovered by a newer generation, enthusiasm generated by the rediscovery tends to obscure the deficiencies ...
