Usually the pyrolysis gas contains 400 to 700 PPm moisture that will be frozen in cryogenic separation, and at a high pressure and low temperature, the white crystal of hydrocarbon mixture will be generated from water and low carbon paraffin hydrocarbon (e.g. CH4, C2H6 and C3H8, etc.). In addition, the crystal of ice and hydrocarbon mixture will also lead to the blocking of pipeline or equipment, resulting in the shutoff of the system. In such a case, the petroleum pyrolysis gas must be deeply dehydrated and dried prior to the cryogenic separation so that the moisture in pyrolysis gas could be reduced to less than 5 PPm (i.e. its dew point is lower than TMP -60 ). Now, the best deep drying adsorbent that is commonly used and generally recognized at home and abroad is 3A zeolite molecular sieve. Since it adsorbs only the moisture present in pyrolysis gas and not the larger hydrocarbon molecules (e.g. C2H6, C2H4,C3H8 and C3H6 etc.), it can prevent the coking of olefin compound within the pore canal of molecular sieve and prolong the service life of adsorbent.
The pore size of 3A molecular sieve is 3A.It does not adsorb any molecular larger than 3A.According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses, ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.
