SOCRATE – PROCESS ANALYZERS BUSINESS UNIT:
SULPHUR RECOVERY UNIT

Sulfur recovery units (S.R.U.) are essential since the discharge of sulphur compounds to the atmosphere is severely restricted by environmental regulations. Typical  hydrocracking brings a lot of sulphur compounds in the outlet sour gas. These gases are processed  by amine plants providing acid gas (AG) and sour water stripping gas (SWS), very rich of H2S (up to 90%) and NH3 (up to 50%). Sulphur in this dangerous gases must and can be recovered for environmental purposes and interesting profitable solid sulphur reselling activity.

CALORIMETRY

Control system philosophy of fired heaters varies
depends on the requirements and design of the heater or boiler. However, in all cases the thermal load of the furnace and the air/fuel ratio are two critical parameters that must be monitored and controlled.
Depending on the control system design the Wobbe Index, the heating value and gas density may be required as input(s).

COMBUSTION EFFICIENCY

Control system philosophy of fired heaters varies depends on the requirements and design of the heater or boiler. However, in all cases the thermal load of the furnace and the air/fuel ratio are two critical parameters that must be monitored and controlled.
Depending on the control system design the Wobbe Index, the heating value and gas density may be required as input(s).

SOCRATE – PROCESS ANALYZERS BUSINESS UNIT:
NATURAL GAS

The most common measure to be applied on Natural gas is flow, achievable by means of orifice fittings, turbines or ultrasonic meters. But SOCRATE applies also other measures that for different reasons can be interesting for quality determination:

  • Calorific Value
  • Water Dew Point
  • Hydrocarbon Dew Point
  • Hydrogen Sulfide (H2S)
  • Total Sulphur
  • Specific Gravity

NATURAL GAS IN ITALY

Natural gas network configuration in Italy is a good testing area for Natural Gas analytical application since it is fed by many different gas sources, with different gas quality and with a very capillary distribution network like nowhere in the world. Thanks to the peculiarity of this gas network SOCRATE has gained very important experience in the field of
natural gas analysis

  • Russia
  • Norway
  • Algeria
  • Libya
  • LNG
  • Internal production (wells)
  • Storage (natural caves/ empty wells)

PROCESS ANALYZERS BUSINESS UNIT:
CALORIFIC VALUE

Calorific value is the amount of heat produced by the complete combustion of a material or fuel measured in units of energy per amount of material (Kj/Sm3). Combining this data with the volumetric flow we can obtain the actual flow of
energy.

PROCESS ANALYZERS BUSINESS UNIT:
WATER DEW POINT

The water dew point is the temperature below which the water vapor in a volume of humid air at a
given constant barometric pressure will condense into liquid water at the same rate at  which it evaporates.
Condensed water is called dew when it forms on a solid surface.

PROCESS ANALYZERS BUSINESS UNIT:
HYDROCARBONS DEW POINT

The hydrocarbon dew point is the temperature (at a given pressure) at which the hydrocarbon components of any hydrocarbon-rich gas mixture, such as natural gas, will start to condense out of the gaseous phase. The hydrocarbon dew point is a function of the gas composition as well as the pressure.

PROCESS ANALYZERS BUSINESS UNIT:
HYDROGEN SULFIDE

Sulphur can be present in Natural gas at different concentration and in different ways, but the most important in terms of quantity and care is Hydrogen Sulfide (H2S) H2S is toxic and becomes harmful above 20ppm.
Hydrogen sulfide reacts with metal ions to form metal sulfides.
It is highly recommended to use process analyzers to measure H2S concentration. Monitoring done in laboratory is dangerous for the operator, is not continuous, (high concentration events could be not seen); Sulphur concentration in the grab bottle can decrease or change due to reaction with internal walls (metal surface) and due to condensation of heaviest components.

PROCESS ANALYZERS BUSINESS UNIT:
SPECIFIC GRAVITY

Specific gravity is the ratio of the density of a substance compared to the density (mass of the same unit volume) of a reference  substance. Temperature and pressure must be specified for both the sample and the reference.

PROCESS ANALYZERS BUSINESS UNIT:
TOTAL SULFUR

Even if elemental sulfur is non-toxic itscompounds such as carbon disulfide, hydrogen sulfide and sulfur dioxide are toxic. The sulfur contamination of a gas or a liquid has to be measured in order to determine the sulfur compounds
that will be produced as the effect of the process.

A sulfur online analyzer determines the total sulfur content of liquid or gas phase samples to ensure process optimization and maximum uptime. It replaces labor- intensive laboratory grab samples with online analysis for rapid determination of sulfur contamination.

PROCESS ANALYZERS BUSINESS UNIT:
TUNABLE LASER DIODE ANALYZERS

Tunable laser diode analyzers are used for continuous emission monitoring and process control across a wide range of industrial applications e.g. in steel, aluminium and other non-ferrous metal, chemical, petroleum and cement production, power generation and waste incineration.

PROCESS ANALYZERS BUSINESS UNIT:
GASCHROMATOGRAPHS

Gas chromatography is a type of chromatography used in analytical chemistry in order to separate and analyze compounds that can be vaporized without decomposition. Its typical uses include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such
components can also be determined). In some situations gas chromatography may help in identifying a compound.

PROCESS ANALYZERS BUSINESS UNIT:
MASS SPECTROMETERS

Mass spectrometry is an analytical chemistry technique that helps identify the amount and type of chemicals present in a sample by measuring the mass-to-charge ratio and abundance of gas-phase ions. Mass spectrometry works by ionizing chemical compounds to generate charged molecules or molecule fragments and measuring their mass-to-charge ratios.

PROCESS ANALYZERS BUSINESS UNIT:
RAMAN SPECTROMETERS

Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system.

Our solution provides rapid, accurate and stable monitoring of physical properties and chemical composition of liquids, emulsions, slurries and solids.

PROCESS ANALYZERS BUSINESS UNIT:
ASTM ON-LINE ANALYZERS

ASTM standards are those developed in cooperation with ASTM (American Society for Testing and Materials) International.

ASTM International has no role in requiring or enforcing compliance with its standards. The standards, however, may become mandatory when referenced by an external contract, corporation, or government.

• Flash point (ASTM D92, 93, IP34, 170)
• Freeze point (ASTM D8326)
• Cloud point (ASTM D2500, 5771, 5772, 5773)
• Cold Filter Plugging Point (ASTM D6371)
• Vapor Pressure Analyzer (ASTM D6377, 6378, 6897)
• Color analyzer (ASTM D156, 1209, 1500, 1544,…)
• Opacity analyzer ASTM D1209 – ISO 6271)
• Distillation analyzer (ASTM D86)
• Viscosity analyzer (ASTM D445)

PROCESS ANALYZERS BUSINESS UNIT:
BLENDING AND FTIR APPLICATIONS

The product properties are monitored in real time at the mixer during the blending, but this require an analyzer with the following characteristics:
• The analyzer shall guarantee that the gasoline will meet specificific requirements in terms of quality and physical properties with high accuracy.
• The on line analyzer shall provide analysis in real time to allow eventual on line recipies correction.
• The online analyzer shall meet at least the ASTM requirements for accuracy and auto validation.

PROCESS ANALYZERS BUSINESS UNIT:
INTEGRATION AND SAMPLING SYSTEM

 A good analyzer with a bad sampling system will result in a bad analysis system.
An analyzer shall operate in the correct ambient conditions.

A good sampling system matches process with analyzer keeping in consideration
what needed to guarantee sample at the analyzer representative to the actual process.

Sample composition, sample phase, process pressure and temperature, dewpoint,
density, and more, are considered to evaluate the kind of sampling system to:

FAST LOOP CALCULATION

Lag time must be calculated and minimized to guarantee representative sample to analyzer, considering pressure, temperature viscosity, density and distances, as well as sample flow to the fast loop.

PHASE CALCULATION

To guarantee sample characteristics it is necessary calculate the phase curve depending on sample compo- sition.

Avoiding liquid in sampling system is mandatory to guarantee a correct sampling condition.
