Gas monitoring instruments and systems for nitric acid process

Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...

DETERMINATION OF FATTY ACID METHYL ESTER (FAME) CONTENT IN DIESEL FUEL OR DOMESTIC HEATING FUEL BY MID-IR SPECTROSCOPY

Presence of fatty acid methyl esters (FAME) in diesel fuel or domestic heating fuel (both hereinafter referred to as diesel fuel) is a signal of blending with biodiesel. The control of FAME content in diesel fuel is an essential and actual task because of the need of the right fuel identification and registration of possible FAME impact on engines and fuel systems. To control the compliance one of the most accurate, rapid and simple methods is EN 14078:2014. Lumex Instruments provides user-friendly analytical...

Industrial Solution for gasification & synthetic gas

Gasification and synthetic gas production from various waste products are becoming increasingly important energy recovery technologies. Often, the synthetic gas contains various hazardous contaminants including H2S, HCl and other acids, heavy metals, and tars. The gas requires cleaning before it is introduced in the engine or boiler. Most of these processes generate significant concentration of tars. The tars can vary from very low molecular weight to large and complex chains.

Anaerobic water purification systems for oil and gas

Gas Desulphurisation is notoriously difficult for small to medium sized sulphur sources and for ‘lean’ acid gases in particular. Most other solutions result in either high operational cost or in laborious operations. Or both… This is where THIOPAQ® Oil & Gas offers you a way out.

Continuous emissions monitoring for sulphuric acid production plants

The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.

Raw-gas monitoring for scrubber optimizing

The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.

Air filtration and gas purification solutions for preservation

The location of the files in an appropriate environment is a necessary condition to preserve them properly. There are numerous studies that identify environmental pollution as the main problem for the conservation of historical objects. Acid gases, such as sulfur, nitrogen and carbon oxides, are the most widespread form of pollution, and they acidify archival materials, accelerating deterioration. The powder has hygroscopic properties, which results in an increase in the humidity of the material, causing the...

Filtration for Flue Gas Analysis and CEMS

Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3,...

Salt Water Disposal - Operational improvements and savings

Adding Wilsa ElectroWaveTM technology to existing separation equipment at Salt Water Disposal Wells (SWD) or Salt Water Injection Wells (SWIW) has a profound impact on the amount of oil can be recovered without using chemicals. Additionally there is a host of operational improvements and savings that result from the Wilsa Effect. Oil free solids settle out faster for cleaner, clearer brine for injection. Cleaner brine means less injection pressure and fewer acid jobs in the formation. Pump packings last...
