moisture absorbing agent

Introduction

Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. The pore size 13X molecular sieve is about 10 Å . It can absorb any molecular smaller than 10 Å , mainly used as catalyze carrier, co-absorption of CO2 and H2O, H2O and H2S, as desiccant for medical and air compressor system, and can also be adjusted to fit other various applications.

Application

Molecular Sieve 13X is mainly used for refinement since it implements simultaneous absorption for bi-molecule and tri-molecule and can be applied for liquefied and gaseous materials on the whole. Main absorbing target are carbon dioxide, sulfuretted hydrogen and mercaptan including water and it can absorb all the material whose molecular diameter is less than 10A.

It absorbs,in sequence of absorption rate, SF6, CHCL3, CHBr3, CHI3, N-C3F8, CCL4, N-C4F10, N-C7H16, CBr4, C6H6, B5H10, (CH3)3N, C(CH4)4, (C2H5)3N, C(CH3)C3CL, C(CH3)3Br, and C(CH3)3CH.The main uses are as follows.

1) Air refining (removing CO2 and H2O).

2) Removal of mercaptans and hydrogen sulphide from natural gas using patented  Zeochem technology.

3) Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc).

4) Oxygen PSA (Pressure Swing Adsorption) process.

5) Special double glass (removing solvent and grease).

Technical specification

Regeneration

1.Removing the moisture

You May use the dry gas like nitrogen, the air, the hydrogen, the saturated hydrocarbon and heat the gas up to 150-320 °C. Firstly you need let the hot gas purge through the molecular sieve bed with the pressure of 0.3-05kg/m2 for 3 to 4 hours. Then change to dry cold gas for 2-3 hours, at last you need isolate the molecular sieve from air and cool it to room temperature.

2.Removing the organics

You can use the water vapor to take the place of organics, then use the method 1.

You can also use the hot water vapor or inner gas pass through the molecular sieve under the temperature of 200-350°C (couldn’t use the gas which will explore when to mix with the adsorbed organics).

3.Removing the gas

You can reduce the pressure to regenerated the molecular sieve.
