First Class Design for Protection of the Environment
TAIL GAS TREATING SYSTEM- TGTU
Rameshni & Associates Technology & Engineering (RATE) offers Licensing technologies in sulphur technologies and tail gas treating for upstream, to midstream and downstream with full performance guarantees. RATE offers valid patented technologies that are grantedto RATE by USA Patents and Trade Mark Office.
The SO2 reduction can be implemented incremental at each facility over the years to reduce the SO2 emission to less than 10 ppmv.
No pre-investment would be required, the budget can be allocated only on the current emission.

TAIL GAS HYDROLYSIS REACTOR
TG-MAX is the patented technology by RATE
To Meet overall recovery of SRU & TGU to 99.99% or SO2 emission less than 50 ppmv.
the pit vent is recycled to the sulphur recovery reaction furnace.
RATE COS / CS2 hydrolysis reactor in the Tail Gas Unit (TGU), is an additional reactor after hydrogenation reactor to maximize the hydrolysis of COS and CS2 and to minimize the SO2 emission.
The advantage is to eliminate the caustic scrubber after the incineration.
CATALYTIC TAIL GAS INCINERATION MAX (CTI-MAX)
CTI-MAX is another catalytic tail gas incineration compromising of using TGU low temperature catalyst and selective direct oxidation catalyst.
The existing sulphur recoveries are 3 stage Claus, and 3-stage Claus with direct oxidation similar to SMAX. Adding CTI-MAX and to produce ammonium sulfate type product is attractive because the product can be sold. Both ammonia and SO2 will not be wasted.
RATE licenses 2-stage sour water stripper with high purity ammonia as well as CTI-MAX.
