Purification solutions
Trusted leader in purification solutions for gas processing
We provide absorbents and technologies used for the purification of natural gas, hydrocarbon gas, liquefied natural gas,and sustainable feedstocks. Our absorbents are used to remove impurities from gas during processing. Johnson Matthey's PURASPEC™ absorbents are designed to remove traces of contaminants from natural gas, hydrocarbon gases and liquids. The absorbents target and remove impurities – such as mercury, arsine, hydrogen sulphide and carbonyl sulphide – to non-detectable levels. As well as the absorbents themselves, we provide a technology package complete with detailed engineering, piping and instrumentation specifications.
PURASPEC: impurity absorbent solutions
Johnson Matthey’s PURASPEC absorbents offer high-capacity, cost-effective solutions that extend bed life and reduce the need for frequent replacements. These robust, low-emission solutions are designed to remove impurities like sulphur compounds, mercury, and halides from hydrocarbon gases and liquids. Widely used for natural gas processing, and increasingly for sustainable feedstocks, PURASPEC enables reliable, efficient operation while minimising downtime and costs.
The PURASPEC made-to-measure process delivers a wide range of operating benefits including: environmentally friendly reprocessing, high operating flexibility, low pressure drop design, and easy retrofitting.
PURAVOC: cost-effective purification by catalytic oxidation
Our PURAVOC™ technology provides a catalytic oxidation solution to remove a broad variety of volatile organic compounds (VOCs), oxygen, hydrogen and carbon monoxide from various gas stream sources. PURAVOC catalysts can be used in traditional chemical processes and emerging sustainable fuels and energy applications.
PURAVOC offers a range of platinum group metal (PGM) fixed bed catalysts, utilising our 200+ years expertise in PGM chemistry. They are specially designed to oxidise individual or complex gas impurities to very low levels, at low temperatures compared to thermal processing and with minimal intervention. As a result, PURAVOC can achieve long and dependable bed life at reduced operational expenditure, making this a very economical solution.

Sulphur removal absorbents
Our PURASPEC™ absorbents are proven over the last four decades to be a simple and effective solution to remove sulfur to very low concentrations within the gas processing, refining and petrochemical markets. These are also finding home in emerging sustainability and decarbonisation driven technologies such as renewable and recyclable feeds, and CCUS.

Arsine removal absorbents
Our PURASPEC™ absorbents have proven over the last two decades to be highly effective and selective for the removal of arsine from light liquid hydrocarbon streams. These streams commonly originate from cracking of heavy hydrocarbon streams such as FCC or olefin steam cracking.
