Why does using Hengye Molecular Sieve for Ethanol Dehydration matter?
Quality Ask to see our Certificates of Analysis from recent production lots, which supplement our provided specification sheets.
Working Capacity A 1% difference in operating efficiency – working capacity could represent a one million gallon yield difference each year. At $2/gallon, that’s 2 million dollars per year!
Durability Molecular Sieve, in this application, should last 7 years. Inferior durability, crush strength, and attrition will reduce the service life of the Molecular Sieve.
Efficiency The Hengye Inc., team will calculate the efficiency of your system upon request and explain the various physical attributes of Molecular Sieve to assist in your decision making.
Technical Support A top priority at Hengye Inc. is to give our customers end-to-end Technical Support over the long term so that customers have the right product for the task at hand.
Cost Savings With large amounts of product in your ethanol dehydration system, it’s easy to understand how small differences in temperature or a miscalculation from product quality can lead to significant losses or gains in profitability and at Hengye Inc. we will support you every step of the way.
Molecular Sieve is widely used in the biofuel industry for removing water from ethanol in the generation process. Ethadry, a Hengye Inc. product, has been designed specifically for use in ethanol production, and can improve an ethanol dehydration unit’s dynamic adsorption capacity of water, raise ethanol output, all while reducing by-products.
Through distillation alone, ethanol can only to dehydrated to around 95% to 97% purity, with the remaining water unable to be removed due to the formation of an azeotrope, leaving the ethanol unsuitable as fuel. To achieve fuel purity ethanol, pressure swing adsorption (PSA) technology along with the use of Molecular Sieve is applied, and anhydrous ethanol with the volume fraction of 99.5% to 99.98% (v/v) can be achieved.
