ActiSorb GP 100 Series SULFUR REMOVAL The ActiSorb GP 100 series of catalysts and adsorbents are used for the purification of hydrocarbon gas streams that contain hydrogen sulfide (H 2 S), mercaptans (R-SH), and carbonyl sulfide (COS). These products deliver maximum activity and can be used under varied conditions. Optimum performance is influenced by sulfur concentration of the feed gas, flow rate, temperature, pressure, and water content of the gas stream. Benefits High pick-up capacity lowers operating cost Flaring is avoided so combustion pollutants such as SO 2 and CO 2 are not produced Enable compliance with gas pipeline specifications and regulations Free flowing at removal, so water blasting and subsequent waste water treatment are not required Excellent physical integrity to withstand upsets like water or liquid hydrocarbon carry-over Offers design flexibility, or use as drop-in replacement Superior crush strength with stable pressure drop over the operating cycle. PRODUCT ActiSorb GP 101 ActiSorb GP 102 ActiSorb GP 103 ActiSorb GP 104 ActiSorb GP 105 SIZE AND SHAPE 4, 8, 10 mm 3x4 mm Tablets 4.5 mm 4.8 mm 2.5 mm DESCRIPTION Formed from high-grade iron oxide by a proprietary method to provide a high surface area, this industry proven adsorbent is for the removal of H 2 S in natural gas with high CO and CO 2 gas streams. High capacity H 2 S adsorbent for severe operating conditions and where maximum sulfur adsorption is required. Formulation eliminates pressure drop increase, prevents agglomeration, and is non-hazardous. High capacity H 2 S adsorbent for severe operating conditions and where maximum sulfur adsorption is required. High activity zinc oxide is manufactured to produce a surface area in excess of 50 m 2 /g. Operates at ambient temperature, with increasing pick-up as temperature increases period. Copper-Zinc double promoted material that provides unique chemistry for sulfur adsorption at ambient temperatures.

ActiSorb GP 150 Series ORGANIC SULFUR ADSORBENTS Sulfur removal is an important and often necessary step in the gas processing to meet pipeline and export regulations. Many effective products are available to remove hydrogen sulfide (H 2 S) but few options to effectively remove organic sulfur molecules. ActiSorb GP 150 series was developed specifically to remove the more difficult compounds such as mercaptans and thiophenes. Several criteria should be considered when selecting a ActiSorb GP 150 series product. These include: Inlet H 2 S content Types of sulfur compounds found in the feed stream Operating temperatures and pressures Outlet sulfur requirement Desired change-out frequency Availability of hydrogen PRODUCT ActiSorb GP 151 SIZE AND SHAPE 1.6 mm Tablets ActiSorb GP 152 0.5-1.4, 1.7-4.8 mm Granules ActiSorb GP 153 ActiSorb GP 154 2.5, 4.8 mm 1.6 mm DESCRIPTION High activity catalyst developed to remove H 2 S, specifically mercaptans, disulfides, and thiophenes in gas or liquid phase streams. Low cost, regenerable solution provides effective removal of both mercaptans and H 2 S at ambient temperatures. Ideal for gas and hydrocarbon streams with low to moderate sulfur levels. Mixed metal oxide formulated to provide a wide range of sulfur adsorption options. Removes sulfur compounds, including THT, DMS, and mercaptans in natural gas, LPG, biogas, and CO 2 from gas stream under ambient conditions. 7
ActiSorb GP 200 Series COS HYDROLYSIS The removal of carbonyl sulfide from process feed streams such as natural gas, partial oxidation gases, liquid propylene and propane, and CO 2 is accomplished by several chemical reactions. Carbonyl Sulfide (COS) can be converted to hydrogen sulfide through hydrogenation via the following reaction: (1) COS + H 2 <-> CO + H 2 S For syngas from coal and heavy hydrocarbon gasification with high concentrations of H 2, CO, and H 2 S, the high COS equilibrium level makes hydrogenation impractical to achieve COS removal to low levels. One of the most efficient and economical methods is by hydrolysis to form hydrogen sulfide (H 2 S) over a suitable catalyst. This process can result in an essentially sulfur-free gas stream suitable for the synthesis of NH3, CH3OH, and synthesis gas. PRODUCT SIZE AND SHAPE ActiSorb GP 201 3.2 mm ActiSorb GP 202 ActiSorb GP 203 3.2 mm 3.2 mm DESCRIPTION Formulated to convert COS to H 2 S in low CO, HCN, CS 2 environments. The high selectivity ensures that process gases with can be treated economically. Formulated especially for the selective hydrolysis reaction of COS and CS 2 for use with gasification gases containing high CO as well as in natural gases and liquid hydrocarbons. It is manufactured to give the optimum combination of activity, selectivity, and long life. Highly selective catalyst towards COS and CS 2 with excellent poisoning resistance to HCN, and halogens (HCL, HF). Preferred for gas streams with low CO and H 2 S. Via hydrolysis, COS is transformed into H 2 S according to the following equation: (2) COS + H 2 O <-> CO 2 + H 2 S 8
ActiSorb GP 300 Series ARSINE REMOVAL Natural gas frequently contains arsine and other arsenic compounds, such as trimethyl arsine that is not effectively removed with a traditional CuO/ZnO type sorbent. As a result, Clariant supplies a series of adsorbents for the removal of arsenic and heavy metals from natural gas and liquid hydrocarbons streams. The choice of a specific adsorbent depends on the feed stream characteristics, type of impurity to be removed, and the process conditions. PRODUCT ActiSorb GP 301 SIZE AND SHAPE 1.5, 3.2 mm ActiSorb GP 302 6.4 x 3.2, 4.8 x 2.4 mm Tablets ActiSorb GP 303 1.5, 3.2 mm DESCRIPTION Recommended for the removal of As(R) 3 compounds such as arsine, trimethyl arsine, and triethyl arsine. Proven mixed metal oxide adsorbent with good capacity used in gas phase applications. Product purity achieved depends on operating conditions and can be below the detectable limits often 10 ppb. Uniquely formulated for arsine removal in liquid phase applications at ambient temperatures and all pressures. Depending on other contaminants in the stream, this product can achieve levels of less than 5 ppb. 9
ActiSorb GP 400 Series MERCURY REMOVAL For the application of natural gas purification, the mercury content of the gas may be reduced to less than 0.1 ppb (1 microgram/nm 3 ). Clariant s mercury adsorbents represent one of the most efficient and economic mercury purification systems available. We offer a range of carbon-based and metal oxide-based adsorbents that fit many operations depending on feedstock composition, process conditions, and application. The optimal performance balance based on adsorption efficiency, pressure drop, and economics is ensured by the appropriate choice of carbon based or mixed-metal, extrudates or granules.
