The reaction with Samascav and H2S is instant once contact is made. RSH reaction time can take longer depending on the RSH species. Typically, the treatment time required is more a function of the efficiency of the application and nature of the asset that is being treated.
All sulphur compounds react with Samascav.
4000 mg/L (combined H2S & RSH) in liquid phase was tested and was successful. No upper limit has been established.
The product is 100% miscible with water and this is a SINGLE PHASE system only. In liquid hydrocarbon applications, the sulphates, which are created by Samascav, stay in the water phase and are separated from hydrocarbons during normal separation.
Samascav will slightly increase the pH of the water; therefore, analysis has to be carried out to determine the effect of this increase in pH, particularly where there are high levels or suspended solids or calcium carbonates in the produced water.
NONE. - No potential scaling in ordinary environments. The increase of SO4-2 in the water phase will depend on the mole-mole equilibrium between quantity of H2S / RSH and Samascav. Cations such as Barium, phosphorous and others associated SO4-2 deposits once it has reached maximum solubility. Excess Samascav will not cause any deposits.
No, enclosed system; hence no Oxygen ingress.
? It does not decompose thermally within the operating temperature range up to 300 Deg. C
Yes - the amount of increase is directly related to the amount of H2S / RSH treated by the chemical.
No special mixing tooling required with water but for optimal results, it is recommended to always inject at the inlet of the inline / transfer pump. In gas lines, inject with sprayer nozzle under positive pressure. For heavy crudes and HSFO, it is recommended to inject as early as possible or at pump inlet to ensure efficient mixing.
There is complete separation from the hydrocarbon phase, and the speed of the separation can be adjusted by adjusting the specific gravity of the chemical.
