Supply of Sulphonated Asphalt
Reference: SSG1718P17/05 7/14/2016, Location: Asia
Category: Corrosion Products/Services
Scope of Work
The company invites bids for the supply of Qty= 4000 BAG, Sulphonated Ashphalt:
- Description of the product and use:
A partially water soluble sodium salt of sulphonated ashphalt used for shale / clay inhibition and to prevent sloughing of problematic splinttery shales.
- Specifications are as follows:
1. Physical properties: The material, as received, should be a free flowing brown to black coloured powder, free from lump and other foreign matter.
2. Moisture content, measured by drying: 10.00 at 105 +/- 2 degC, % by mass, maximum.
3. Soluble matter content, % by mass
(i) In distilled water: 65 - 70
(ii) In dimethyl chloride: 30 - 35
4. PH of 2% (w/v) solution in distilled water a: 8.5 26 +/- 2 degC, minimum
5. Qualitative test for presence of sulphonate group.: Positive
6. Barium chloride test: Mix 1% (w/v) of the sample in distilled water and stir in multimixer for 10 minutes to this add 150 ml distilled water and 0.5 gm barium chloride (LR grade) and again stir for 10 minutes in multi mixer. Pour the content to a beaker and observe after 30 minutes. No formation and setting of black coloured precipitates should take place.
7. Performance Test:
A. Lubricity test : Prepare a 7.5% (w/v) bentonite suspension in distilled water using OIL approved bentonite and stir the suspension for 15 minutes in multimixer so that no lumps are left after the stirring period. Age the suspension for 72 hrs at 90 +/- 2 degC. After the lapse of the aging period, cool the suspension and stir for 15 minutes in multimixer. Adjust apparent viscosity for the suspension to 15 cp by dilution with distilled water, if distilled water, if necessary. Treat the suspension with 2.0% (w/v) sulphonated ashphalt sample and stir for 30 minutes in multimixer for lubricity test. Determine lubricity co-efficient using a standard mud lubricity tester.
Lubricity co-efficient should not be more than 0.30
