Installation for the Capture of light Fractions of Hydrocarbons and oil Products

As you know, oil is a complex mixture of a very large number of individual hydrocarbon components. During evaporation, the lighter fractions, such as methane, propane, ethane, butane, isobutane, etc. are lost in the initial stage. They are called VOCs — volatile organic compounds.

Losses of petroleum products (gasoline, fuel) that occur during their transportation, storage, reception and dispensing can conditionally be divided into natural, operational and emergency.

The advantages of using ULFU systems

• almost completely eliminate the loss of light fractions of hydrocarbons from tanks;
• significantly reduce the fire and explosion hazard of objects;
• to improve the condition of the air basin in the area of the tank farm and oil loading systems (gasoline, fuel);
• reduce harmful emissions into the atmosphere and improve the environmental situation;
• preserve the properties of petroleum products (gasoline, fuel);
• get extra profit.

Complete set of the unit for trapping light fractions UULFU

• skid on which all equipment is installed;
• column and downpipe into the atmosphere;
• refilled activated carbon and glycol.

Hardware Description

• electrical equipment - all instrumentation, safety devices and motors are explosion-proof.

Scope of supply for each installation of ULFU

• compressors using propylene and ethylene as a cooler;
• air-cooled condenser for cooling cycles with propylene;
• 3-stage hydrocarbon condenser with coils from finned tubes of the first stage;
• pressure tanks for the cooling cycle including the receiver, expansion tank and suction tanks / accumulators;
• hydrocarbon reservoir and pump;
• programmable logic controller with IP45 for remote installation;
• initial cooler and grease;
• description of the logical control system (electronic version of the PLC circuit diagram);
• spare parts for commissioning.

Operational restrictions

• ambient temperature in the shade: -20 ° C to 40 ° C;
• air supply for instrumentation: 6 bar g., -40 ° C dew point;
• site classification: Zone 1, Group IIA / B, T3;
• electrical power: 415V, 3 Ph, 50 Hz, 3 phase + neutral + ground.

Operation if these restrictions are not observed may require modifications.

The cooling and defrosting pipe must be made of copper. Brass check valves, according to the refrigeration industry standard. Hydrocarbon piping (excluding cooler) of 316SS with all flanges in accordance with ANSI B16.5, class 150 #. Pipes of 316SS with fittings can be used for hydrocarbon piping of 20 NB or less.
