Sulfur Recovery

Atmospheric emission regulations have been tightened to specifications of less than 150 mg of SO₂/Nm³, while gas fields are being developed with increasingly high levels of H₂S. The H₂S present in acid gas streams can be valorized by oxidation to elemental sulfur through Sulfur Recovery Unit. In turn, elemental Sulfur is used in the fertilizer and rubber industries, and for the extraction of some metals (copper, nickel, uranium), mainly via its intermediate conversion into Sulfuric Acid (H₂SO₄).


Axens Offer

AdvaSulf™ portfolio provides reliable, flexible and low-cost solutions for Sulfur Recovery to meet the most stringent environmental standards, at minimized capital and operating costs. The portfolio covers a complete range of processes for any applications: gas plants, refineries, upgraders, biogas, shale gas, etc., in a wide range of single train capacities, from a few tons per day to more than 2,200 tons per day of sulfur produced.

Carbon Capture Technology Expo 2023

Carbon Capture Technology Expo Europe is dedicated to discussing the increasing role that Carbon Capture, Utilization & Storage (CCUS) will play in transition to a net-zero carbon economy.
The two-day event will bring together leading engineering firms, technology manufacturers and suppliers, energy firms, the oil and gas sector, heavy industry, chemical companies, various manufacturing organizations, research groups and NGOs, consultants, and government bodies to explore how we can rapidly accelerate the deployment and commercialization of carbon-removal technologies as a key solution on the pathway to net-zero carbon emissions.
