CORROSION INHIBITOR FOR OIL & GAS LINES in Presence of H2S

Corrosion Inhibitionchemicals, which have been successfully used throughout the world over the years. They have been tailored to meet specific corrosion problems and are now applied to topside process streams, main export Oil & Gas pipelines containing H2S. Corrosion Inhibitors give excellent protection from corrosive processes and have been developed to be compatible with all other process chemicals. This product has been developed in our laboratories over a number of years by our team of corrosion experts using state of the art equipment. Corrosion Inhibitors are deployed depending on their function. From field experience, typical dose rates are generally in the region of 5 - 25ppm. These inhibitors are designed to have low viscosity for easy application.

Characteristic and Property

Physical Appearance:   The material shall be a free flowing homogenous liquid at 24 ± 2 °C, free from visible impurities
Viscosity of the Product at 300 rpm using a Fann VG Meter or Equivalent at 24 ± 2 °C, cP………200 (Maximum)
Corrosivity of the Neat Product, mpy………………………………………………………………………1.0 (Maximum)
Compatibility and Emulsification………………………………… The material shall be compatible with the Tendency of the Product with a mixture and shall not form emulsion.

Mixture of Untreated Crude Oil Mix (prepared by mixing 140 ml of Crude……………………………..The interface sludge pad thickness shall Oil with 60 ml of AR Grade Xylene not be more than 5% after five hours.
and Brine Corrodant at 24 ± 2 °C
Thermal Stability Test……………………………………………………….The Material shall be heated in a well sealed glass stoppered measuring cylinder at 80 ± 2 °C for 2 hours in a Laboratory Oven.
Neither precipitate nor heterogeneous layers shall be observed.

6.    Performance Tests :
A. Test Conditions: 
(I) Corrodant Media :
1% (w/v) Sodium Chloride (LR Grade) Solution (Aqueous) saturated with CO2 and deoxygenated with Sodium Sulphite at a rate of 8 ppm per ppm of Dissolved Oxygen in water. CO2 concentration to be 1250 ± 50 ppm at 24 ± 2 °C (II) Metal Coupons :
API - 5LX (30 mmx 25 mmx 3 —4 mm approximately). The surface finishing shall be 320 emery grit free from pits and scratches
(III) Test Temperature: 50 ± 2 °C.
(IV) Corrosion Inhibitor Dose (w/v) with respect to the Aqueous Brine Solution: 25 ppm.
(V) Exposure Period :
(a)    168 hours for Stagnant Test.
(b)    24 hours for Dynamic Test.

B. Performance Test Methods :
(a)    Stagnant (Static) Test.
(b)    Dynamic Wheel Test.

C. Performance Evaluation :
Calculate the Efficiency of the Inhibitor by comparing the Weight Loss of the Coupon in Inhibited System with that in Uninhibited System (Blank Test without Inhibitor addition) after tests under both Static and Dynamic Conditions and Visually examine the condition of the Coupons after each test. 
Inhibition efficiency of the corrosion inhibitor under static as well as dynamic test conditions should not be less than 80%.
The inhibited coupons shall be free from pits on visual inspection, under both test conditions.
Note:Detailed specifications which includes performance test are available on request.

 Advantages

Corrosion Inhibitors, when applied correctly, give excellent protection from corrosive processes including presence of H2S in Oil & Gas pipelines. It is extensively used in oil industry. It is designed to preferentially protect weld treatments from galvanic corrosion. The protection provided by the Corrosion Inhibitor Oil Line extends the life of pipelines and process vessels, thus saving on expensive downtime and materials during repair and replacement.

Toxicity and Handling

It can be stored in closed containers away from direct sunlight at ambient temperature. During handling, direct contact with human body is to be avoided. Safety goggles and gloves are recommended for safe handling.

Packaging and Storage

Products can be supplied in 210 liter drums and as per buyer requirement.
