are usually integrated into a plant containing an amine unit to handle these emissions: • Sulfur recovery units, such as a Claus or catalytic Redox unit for processing the acid gas stream. The sulfur is either sold if recovered in pure form, sent for further processing, or landfilled.

Rectisol Units. A Rectisol Unit is a gas cleaning step downstream of a gasification unit. Certain acidic components like carbon dioxide and hydrogen sulphide are generated during gasification. The Rectisol unit eliminates these acidic components. Air Liquide Engineering & Construction India is a centre of excellence in Rectisol Technology.

The raw gas entering the Rectisol unit is first washed by a mixture of water and hydrocarbons and is thus cleansed of the crude naphtha, ammonia, and HCN and also of any ash remnants that could have abrasive effects in the subsequent process. The gas is then washed with cold methanol to remove H2S, COS and lower thiols.

• Rectisol Unit Water - phthalate esters, phenols, aromatic hydrocarbons, Cd, Cu, Fe, Hg, Ni, P, S, Se, and Zn. The TWOS values for the compressor condensates and Rectisol unit samples turn out to be relatively low because of the small flow rates for these two …

unit sizes, energy use, capital and operating costs, and labor requirements, were developed. Finally, Nexant performed an analysis to determine how changes in syngas flowrates and compositions would impact the designs, for future reference as the plant size changes. The technologies chosen for both cases did not differ considerably.

COAL TO OLEFINS (October 2011) As demand for oil and natural gas outpaces discoveries of new reserves, coal will regain its importance as a source of energy and as a chemical feedstock. At current production levels, proven coal reserves are estimated to last over a century, with recoverable reserves in around 70 countries.

The Rectisol unit accounted for the most emissions, 60.1% of the total, with a CO 2 concentration of 88.1%. Boiler flue gas accounted for 36.4% of total emissions, but the CO 2 concentration was as low as 6.0%. Because the two sources accounted for 96.5% of total emissions, they were the main focus of …

1 A COMPARISON OF PHYSICAL SOLVENTS FOR ACID GAS REMOVAL INTRODUCTION Physical solvents such as DEPG (Selexol™ or Coastal AGR®), NMP or N-Methyl-2- Pyrrolidone (Purisol®), Methanol (Rectisol®), Propylene Carbonate (Fluor Solvent™), and others are becoming increasingly popular as gas treating solvents, especially for coal gasification applications.

Hydrogen is a key raw material for many chemical processes and a clean fuel for various power generation strategies. Coal-to-hydrogen (CTH) conversion is an alternative way to pro

RECTISOL ® can purify synthesis gas down to 0,1 vppm total sulphur (including COS) and CO2 in ppm range.. The main advantages of the process are the rather low utility consumption figures, the use of a cheap and easily available solvent and the flexibility in process configuration.

2 from a Rectisol® unit was transported to the CBM eld and injected into the coalbed, which produced methane. The methane was sent back to the CTO plant to replace the fuel coal in the boilers. Thus, CO 2 emission reduc-tions were derived from both CO 2 sequestration and switching fuels. A CTO plant in Baotou City, Inner Mongolia Autonomous

Synthetic Natural Gas (SNG): Technology, Environmental Implications, and Economics Climate Change Policy Partnership 3 Abstract Increasing demand for natural gas and high natural gas prices in the recent past has led many to pursue unconventional methods of natural gas

Sour natural gas compositions can vary over a wide concentration of H 2 S and CO 2 and a wide concentration of hydrocarbon components. If the H 2 S content exceeds the sales gas specification limit, the excess H 2 S must be separated from the sour gas. The removal of H …

Coffeyville Block Flow Diagram Air Separation Unit Ammonia Synthesis N 2

The Selexol process is similar to the Rectisol process, which uses refrigerated methanol as the solvent. The Selexol solvent is a mixture of the dimethyl ethers of polyethylene glycol. Selexol is a physical solvent, unlike amine based acid gas removal solvents that rely on a chemical reaction with the acid gases. Since no chemical reactions are ...

Rectisol®, independently developed by Linde and Lurgi, is a physical acid gas removal process using an organic solvent (typically methanol) at subzero temperatures, and characteristic of physical acid gas removal (AGR) processes, it can purify synthesis gas down to 0.1 ppm total sulfur, including hydrogen sulfide (H2S) and carbonyl sulfide (COS), and carbon dioxide (CO2) in the ppm range.

While Rectisol is more costly, it is preferred for treating coal-based syngas because it allows for very deep sulfur removal (<0.1 ppmv H 2 S plus COS), and also because it can remove HCN, NH 3, and many metallic trace contaminants (including iron- and nickel-carbonyls, and mercury) to provide additional catalyst protection.

similar) or Rectisol unit with large solvent circulation and large energy consumption is required to enrich the acid gas. The new innovation is a process for recovering sulphur from the syngas streams from the power plants where the sulphur recovery is followed by the SO2 recovery unit and the gas turbines or boilers in either sequence.

Rectisol is the trade name for an acid gas removal process that uses methanol as a solvent to separate acid gases such as hydrogen sulfide and carbon dioxide from valuable feed gas streams. By doing so, the feed gas is made more suitable for combustion and/or further processing.
