Definitions

  • U.S. Patent No. 4,1 12,052 describes the use of hindered amines for nearly complete removal of acid gases such as CO 2 and H 2 S.
  • U.S. Patents Nos. 4,405,581 ; 4,405,583; 4,405,585 and 4,471 ,138 disclose the use of severely sterically hindered amine compounds for the selective removal of H 2 S in the presence of CO 2 . Compared to aqueous MDEA, severely sterically hindered amines lead to much higher selectivity at high H 2 S loadings.
  • the hindered amine ethers are used in the form of aqueous solutions, typically from about 0.1 to 5M concentration in order to secure adequate loading; variations both within this range and outside it may be made according to individual processing requirements, e.g., concentration of gas species in total gas flow, size of unit, etc. In most cases, the rich solution will have an amine concentration of 0.05 to 2.5 M.
  • Conditions in the separation unit will be typical of those used in conventional amine gas purification processes, for example, in temperature swing operation, sorption temperatures are typically in the range of 30-50°C, more usually 40-50°C and desorption temperatures typically at 60 to 140°C, e.g., 100- 125°C.
  • pressure swing operation the sorption and desorption pressures are usually set by the pressure of the incoming feed stream and perhaps also by any requirement for the product stream.
  • This mixture can be prepared in the one-step synthesis, by the catalytic tertiary-butylamination of the corresponding polyalkenyl ether glycol, for example, by the catalytic tertiary-butylamination of triethylene glycol.
  • This mixture is one of the preferred absorbents for use in offshore gas processing.
  • the acute aquatic toxicity predictions in Table 4 indicate absorbents A, B, E and F exhibit toxicity to at least one aquatic organism in the 10-100 mg/l range . Fish appear to be consistently less sensitive than daphnids or algae.
