|Conversion of Light Naphtha to LPG and High Octane Gasoline||
The concept of molecular level cracking and rejoining of light paraffins has been realized through the development of a novel zeolite based catalyst which selectively converts C5, C6 range naphtha to LPG and high-octane/ low benzene gasoline/ aromatics with very low dry gas yield.
|Lube Oil Base Stock(LOBS) through NMP Extraction||The process is used to remove aromatic components present in the feeds (Lube Distillate and De-asphalted Oil). Aromatic compounds have low viscosity index and is detrimental for production of lube oil base stocks.|
|Delayed coking of Petroleum Residual Fractions||Unique design of furnace heater by which temperature can be increased rapidly without deposition of coke inside the heater. It has best energy integration between coking section and gas recovery. Coke produced in this technology is of metallurgical grade. Process conditions are optimized for maximum production of lighter fractions. Coker fractionators are designed to give quality distillate required for downstream hydrocracker.
|Sulpholane Extraction Technology for Production of Food Grade Hexane||This echnology can accept feed with any benzene content and is economical as compared with hydrogenation.|
| Modified Gur Bhatti
|| The modified Gur Bhatti lowers the emissions (Smoke level) and increases production capacity by 15% when compared to the conventional Bhatti. The improved Gur Bhatti has less fuel consumption (25% less than conventional Bhatti) therefore, it has lower carbon footprints. Also, the higher temperature under boiling pans and increased plant life indicate improved fuel combustion and furnace design.
|Bimetallic Pt-Re Reforming catalyst|| Bimetallic Reforming catalyst is used for Petroleum Refining/Petrochemical Industry, for production of motor gasoline blending stock, for production of aromatic rich concentrate of benzene, toluene and xylenes. The catalyst is cheaper than imported catalyst and has better activity, selectivity, stability and regenerability.
|Sulfolane Extraction Technology for Production of pure Benzene and Toluene
||This technology is used to recover high-purity benzene and toluene products from aromatic rich streams like reformate or hydrotreated pyrolysis gasoline (HPG). The aromatics rich extract from the Sulfolane unit is clay treated to remove traces of olefins and individual benzene and toluene products are recovered by simple fractionation of BT mixture.|
| Up gradation of FCC Recycle Oil through Solvent Extraction
||This process is a combination of two processes namely Solvent Extraction and Fluid Catalytic Cracking (FCC). In this process, the bottom of FCC unit i.e. Clarified Oil is solvent extracted. The paraffinic rich raffinate is used as a feed for FCC. This generates additional feed for FCC unit. This addition clean FCC feed gives improved distillate yield and removes polyaromatics (precursors for coke) from FCC feed. The process lowers the coke build up on the catalyst also.|
| Vis breaking of Petroleum Residual Fractions (Soaker with internals)
|| Novelty of this technology is the design of the soaker internals and its arrangement inside the reactor. The fuel oil produced is of better quality in terms of stability. Lighter transportation fuels are produced in higher quantity. Due to lower severity of the process, handling of plant is safe and easy and hence longer time-on-stream is achieved. No major change of hardware is required to implement this very low cost technology.
| Simultaneous Production of US Grade Gasoline and Pure Benzene from FCC Naphtha
|| This technology serves a dual role of recovering high purity benzene (>97 wt. % pure) and producing environmental friendly gasoline (Bz. < 0.4 wt. %) from FCC C6 heart cut stream using extractive distillation without the requirement of a prior-hydrogenation or pre-processing step to saturate di-olefins in feedstock and reduce impurities.
| Production of Paraffin and Microcrystalline Waxes
||Wax De-oiling Technology is used to produce petroleum waxes from petroleum streams. This technology is for production of ‘Paraffin Wax’ and ‘Microcrystalline Wax (MCW)’ from petroleum streams. The key feature of the technology are use of single solvent, lower solvent-to-feed ratio, multi-stage dilution pattern to achieve maximum gains, cost competitive, energy efficient process with tailor made know-how /continuous process back-up.|
| Sweetening catalyst for Refinery Streams
|The process for converting thiols into less deleterious disulfides is termed as sweetening. CSIR-IIP in collaboration with BPCL has developed a sweetening catalyst trade named Thoxcat ES™ which is very effective for LPG sweetening process. The technology has been licensed for commercial production to Lona Industries, Mumbai
