First Class Design for Protection of the Environment.


Rameshni & Associates Technology & Engineering (RATE) offers Licensing technologies in sulphur technologies and tail gas treating for upstream, to midstream and downstream, oil and gas business, mining and smelters and gasification with full performance guarantees. RATE offers valid patented technologies that are granted to RATE by USA Patents and Trade Mark Office.
RATE provides PDP (Process Design Package) or BEDP (Basic Engineering Design Package) for all licensed technologies.

The licensed technologies apply to the new units or the existing units for the capacity expansion; reduce emissions, increasing the recovery or any other major improvements.

Licensing RATE Technologies includes for sulphur technologies, tail gas treating, degassing and gas processing, AGRU, dehydration, hydrocarbon dew point, NGL, LPG, condensate recovery and SWS’s, caustic scrubbing, and mercaptan removals.

  • Full performance guarantees for overall recovery
  • Full performance guarantees for required emissions
  • Full performance guarantees for Design Capacity and normal operation
  • Full performance guarantees for Turndown
  • Full performance guarantees for all products, like treated gas/sales gas, Degassed liquid sulphur
