Product description
1.Describe:
The RIGCHINA Garrett Gas Train kit contains all hardware and reagents required to conduct the procedure according to API Recommended Practice 13B-1, ANSI/API 13B-1/ISO 10414-1. Two types of Draeger tubes are supplied to adequately span the range of hydrogen sulfide concentrations that may be found in water based drilling fluid filtrates and in oil based drilling fluids. CO2 Draeger tubes and 1 liter gas bags are supplied for determination of carbonate concentration. Inert carrier gases, both CO2 and NO2 are supplied for all tests. All items are securely packaged in a waterproof, high-impact plastic carrying case.
Hydrogen Sulfide Test Paper discs (supplied) can be used in the Garrett Gas Train to give a qualitative indication of the presence of sulfide. If the presence of sulfide is indicated by darkening of the paper disc, a Draeger tube should be used for quantitative analysis.
2.Sulfides
Soluble sulfides include H2S and the sulfide (S2-) and bisulfide (HS-) ions. Drilling fluid filtrate is acidified in a Garrett Gas Train, converting all sulfides to H2S which is evolved by bubbling an inert carrier gas through the sample. The gas train separates the gas from the liquid. The gas stream is passed through a Draeger tube which responds to H2S by darkening along its length. The darkened length is proportional to the total sulfide in the drilling fluid filtrate. The low-range Draeger tube, H2S 100/a, (0-120 ppm) turns from white to brownish-black. The high-range Draeger tube, H2S 0.2%/A, (60-4080 ppm) turns from pale blue to jet-black.
3.Carbonates
Total soluble carbonates include CO2 and the carbonate (CO32-) and bicarbonate (HCO3-) ions. Drilling fluid filtrate is acidified in a Garrett Gas Train, converting all carbonates to CO2, which is then evolved by bubbling an inert carrier gas through the sample. The gas train separates the gas from the liquid. The gas stream is collected in a 1 liter gas bag (to allow CO2 to mix uniformly) and subsequently drawn through a Draeger tube at a fixed flow rate. The Draeger tube responds to CO2 by progressively staining purple along its length. A reaction between CO2 and a hydrazine chemical causes a crystal violet indicator to turn purple. The stain length is proportional to the total carbonate concentration in the filtrate.
