Ethylene must be Pure and Dry
Ethylene must be Pure and Dry Ethylene must be pure and dry… but ironically, unsaturating olefin/paraffin molecules, is a watery, steamy business! Unfortunately, massive petrochemical molecules don’t just conveniently fall apart into useful bits and pieces. It requires a significant energy investment in terms of live-steam at 750-950°

Cracking Fossil Fuels: The Role of Molecular Sieves
Cracking Fossil Fuels: The Role of Molecular Sieves Separating (cracking) useful olefins or alkynes from paraffins is the key to profitability in this industry; however, it is constrained by the immense costs. The single most produced organic chemical worldwide is ethylene, at more than 150,000,000 metric tonnes per year. We have

Fracking Gas: The Role of Molecular Sieves
Fracking Gas: The Role of Molecular Sieves For humans, dehydration is a very bad thing, but for Natural Gas (methane), nothing could be better! Natural Gas cannot be overloaded with water vapor because that adds unnecessary weight (mass) and takes up volume, which decreases the efficiency of our transportation methods.

The Role of Coadsorption
The Role of Coadsorption Molecular Sieve Manufacturing All Type A molecular sieve originates as Type 4A zeolite crystals. These 4A zeolite crystals can be treated to an ion exchange to create 3A or 5A molecular sieve. To create Type 3A zeolite, larger potassium ions exchange for smaller sodium ions within
