First Class Design for Protection of the Environmen


Rameshni & Associates Technology & Engineering (RATE) has the unrivalled ability to address all sulphur removal and handling issues across all industry sectors including gasification in power plants.
FUTURE. RATE has recently patented a new process for integrating sulphur recovery methods in power plants titled as INTEGRATED SULPHUR RECOVERY METHODS IN POWER PLANTS. The new innovation has superior advantages in the operating and the capital cost saving over the conventional methods with less process units, and less equipment. The acid gas removal is eliminated, instead SO2 recovery takes place for both acid gas removal and tail gas treating. In addition the new technology is integrated with the carbon capture and CO2 removal.

Gasification of coal and other heavy feedstocks will become a larger scale source of Claus sulphur in future. Gasification is currently playing an important role in meeting energy needs in the U.S. and around the world. Typical raw materials for gasification include coal, petroleum based materials (crude oil, high-sulphur fuel oil, petroleum coke, and other refinery residuals), gases, or materials that would otherwise be disposed of as waste. The feedstock is fed to the gasifier with steam and oxygen at high temperature and pressure in a reducing (oxygen-deprived) atmosphere to generate the syngas. Now, driven market an increasing power and chemicals, which necessitate removal of sulphur from SYNGAS prior to chemicals and power production. The main route from coal to chemicals is to fertilizer, coal to liquid, carbon capture and power generation and several others. RATE offers full performance guarantees for the offered technologies.
