Shell Cansolv – Gas absorption solutions articles

The CANSOLV® System scrubbing technology is the leading regenerable SO2 scrubbing process. It uses an aqueous amine solvent in a conventional amine treater process flowsheet configuration to achieve high-efficiency removal of SO2 from a large variety of gas streams. The technology is applicable to petroleum refining,

Significant progress has been made in the last 25 years in the control of emissions resulting from the burning of sulfur bearing fuels and from other industrial processes. The dominant desulfurization technology today is limestone or lime-based scrubbing in various forms. While in general reliable and, in some forms, capable of high SO2 removal efficiency, they produce large quantities of low value waste products, are relatively expensive to build and operate and are difficult to retrofit i

Three reference plants utilizing the CANSOLV® System aqueous diamine based regenerable SO2 scrubbing technology are now operating in regular commercial production. A unit in Europe is treating the tailgas from an incinerator burning a combination of Claus sulfur recovery unit tailgas and a sulfur and chlorine containi

This is a TWST Interview with Colin Ryan, CFO of Cansolv Technologies Inc.
SECTOR – POLLUTION & TREATMENT CONTROLS(WAR614) TWST: Could you begin by giving us a brief overview of Cansolv Technologies?

Mr. Ryan: Cansolv Technologies Inc. was founded in 1997 by a group of entrepreneurial technology developers from Union Carbide (now Dow Corporation). This team had worked together in the late 1980s and early 1990s developing CANSOLV SO2 Scrubbing, a chemistry-enabled proc

Over the past five years, the CANSOLV® system SO2 scrubbing technology has moved from the status of an emerging technology to that of a commercially realized and technically proven process for economical and highly selective regener

The tail gas from a single absorption sulfuric acid plant typically contains 2000-3000 ppmv of unreacted SO2. Emission regulations for new plants in most jurisdictions today require cleanup of this stream prior to discharge into the atmosphere and many grandfathered units are being required to decrease emission levels. The current paradigm is to add a second stage of conversion, which reduces the SO2 concentration to 100-500 ppmv. Studies indicate that the CANSOLV“ System SO2 scrubbing te
