Sulfur Removal

CLS has been removing complex S compounds from hydrogen/hydrocarbon streams for over 15 years specializing in   removal of mercaptanic, thiophenic and benzothiophenic species. 

The net effect of zeolitic sulfur guards from CLS Industrial Purification is a higher capacity and smaller mass transfer zones, leading to longer cycle lengths.

Each year, regulations are introduced, increasing the standards and tightening sulfur specifications in distillates. Meeting these regulations and protecting operating units make sulfur guards a vital necessity in today's refining environment.

Benefits:

1. Performance independent of moisture content of gas.
2. Can perform at ambient temperature not dependent on lattice diffusion
3. Steam out during purging means no requirements for hot nitrogen
4. Faster purging times.
5. Free flowing spent material - much faster change out times.
6. Encapsulation of contaminants.
7. Spent product can be disposed of as Class 2 Non – Hazardous waste.
8. High activity means small mass transfer zone (mtz) leading to high bed utilization

Upstream

After 15 successful years of reinventing Cl removal and S removal in oil refineries, CLS has focused its R&D efforts on solving contaminant problems plaguing the upstream industry. Mercury is rapidly becoming a huge problem.

Mercury occurs naturally in natural gas and oil, it’s highly toxic representing to health and also the environment, known to be a cause of catastrophic equipment failure through Liquid Metal Embrittlement (LME) or amalgam corrosion.

Mercury removal is a necessity when natural gas is either processed or liquefied in a gas processing or LNG plant. 

Treatment using CLS N CAP technology Hg guard absorbent provides the most robust and efficient mercury removal solution that reduces toxicity while protecting plant and equipment. 

With oil shedding its normal cyclic pricing schedule in favor of a first ever enduring low price, oil companies are taking a very serious look at costs when assessing the next major play. The same cost urgency also applies to producing fields that now demand a practical, efficient, and cost effective method for removal of Hg and H2S. 

CLS has now applied its Vari-Zeo technology - tried and tested downstream - to these efforts. In combination with noble metals, CLS has created a very cost effective material which can remove increased levels of contaminants, with a smaller mass transfer zone (mtz), not susceptible to liquid carryover, and able to be steamed at discharge. Once again, CLS is reinventing the way contaminants are removed.
