Chloride absorbent

Chloride in feedstocks can pose a serious threat to ammonia and hydrogen plant productivity if allowed to poison downstream catalysts or harm equipment. Our HTG-10 chloride absorbent eliminates this risk and safeguards your operations.

Ideally positioned between your hydrogenation catalyst and your zinc oxide sulfur absorbent, the HTG-10 effectively absorbs any inorganic chloride your feedstocks might contain, thanks to its high-capacity potassium active sites and special alumina carrier.

Chloride removal across wide temperature range

An optimized chemical and structural design makes the HTG-10 uniquely capable of removing chloride under a wide range of operating temperatures. Compounding the advantages of potassium active sites and the alumina carrier, the HTG-10 features an optimized pore system that can handle approximately 10% more chloride per cubic meter of reactor volume compared to its predecessor – while also removing other halogens, such as fluorides, bromides and iodides.

Flexible and easy-to-use

The HTG-10 normally operates in conjunction with and under the same operating conditions as your desulfurization catalysts, with operating temperatures dictated by your hydrogenation catalyst (normally between 300 and 400°C).

As a plug-and-play absorbent, the HTG-10 does not require any special procedures during loading or start-up.

Maximum utilization

Thanks to its steep absorption front, the HTG-10 ensures maximum utilization of the absorbent and reactor volume – and the full benefit of effective chloride removal. 

Uniform absorption of chloride, thanks to an even distribution of active sites throughout the spherical pellet, is another feature of HTG-10 that ensures full absorbent utilization. The spherical shape of HTG-10 has the additional advantage of maximizing packing density and mechanical strength, resulting in long-lasting and superior chloride removal per unit volume of the reactor.
