Regeneration Molecular Sieve, Activated Alumina, and Silica Gel can all be regenerated, meaning they can be treated to remove what has been adsorbed, so that the product can be used repeatedly. Both heat and/or vacuum can be utilized to bring molecular sieve to a state of being regenerated. Refer

Petrochemicals, Ethane, & Ethylene: Partners in the Plastic Parade Ethane is extracted from Natural Gas, comprising from 1-6% of its volume. The majority of the remainder is methane. Ethane is also a by-product of the Petrochemical refining industry. Its primary use is as a feedstock to manufacture ethylene. Ethylene (aka
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 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
