On the processes and technologies for pentane desulfurization
Thread Content
The broad prospects for the advanced processing of C5 are becoming increasingly evident. However, the sulfur content in C5 products sometimes exceeds the allowable limits; it is difficult to remove, and the removal cost is high. I wonder if my colleagues have any advanced technologies; let’s discuss them together.
Ultra-deep desulfurization adsorbent for carbon-containing pentaconjugated diene feedstocks, as well as its preparation method and applications. Application number/patent number: 200810240549. The present invention relates to an ultra-deep desulfurization adsorbent for carbon-containing pentaconjugated diene feedstocks, as well as its preparation method and applications. The desulfurization adsorbent used is composed of elements selected from reduced group VIII transition metals with activated sulfur-containing molecules, reduced group IB transition metals, and an alumina carrier. This adsorbent can remove almost all sulfides from carbon pentadiene-conjugated diene feedstocks, yielding carbon pentadiene feedstocks with a sulfur content of less than 10 ng/μl.

The new desulfurizing agent developed by the Northwest Institute of Chemical Engineering was successfully applied in the C5 fraction hydrogenation project. The C5 fraction hydrogenation production unit, whose process design was carried out by the Sinopec Shanghai Research Institute and whose engineering design was done by the Sinopec Qilu Research Institute, was put into operation at Zhongyuan Ethylene on October 17, 2008. Using mixed C5 fractions derived as by-products from refinery operations and ethylene production as raw material, this unit is capable of supplying 30,000 tons per year of high-quality cracking feedstock to Zhongyuan Ethylene. The C5 fraction hydrogenation production unit, whose process design was carried out by the Sinopec Shanghai Petrochemical Research Institute and whose engineering design was done by the Sinopec Qilu Petrochemical Research Institute, was successfully commissioned at Zhongyuan Ethylene on October 17, 2008. Using mixed C5 fractions produced as a by-product of refinery operations and ethylene production as raw material, this unit is capable of supplying 30,000 tons per year of high-quality cracking feedstock to Zhongyuan Ethylene. It holds great practical significance for the rational utilization of by-product resources from C5 fractions in order to enhance the competitiveness of China’s petrochemical enterprises. The T320 room-temperature desulfurization agent developed by the Catalyst Company of the Northwest Chemical Industry Institute has been successfully applied in this production facility. Process conditions: room temperature, pressure: 0.28 MPa, space velocity of 900–1000 h-1, inlet H2S
Thank you for your detailed answer. I have come across this desulfurizing agent online, but I’m not sure about its actual performance in practice. What is the usage cost? Additionally, can this desulfurizer be regenerated? Thank you.
