Molecular Sieve

Molecular screening has established itself as a differentiated technology in the sugarcane and energy sector for the production of anhydrous ethanol, and JW stands out as a leader in this segment, with more than 25 installed plants, totaling a significant production of approximately 14,000,000 liters/day of anhydrous ethanol. Designing equipment that meets both ANP (Brazilian National Agency of Petroleum, Natural Gas and Biofuels) standards and export requirements, offering distinct advantages that increase operational efficiency.

Among the notable characteristics of these systems is the predominant use of low-pressure steam as a heat source, resulting in energy efficiency and reduced operating costs. Furthermore, the equipment exhibits low specific steam and water consumption, contributing to more sustainable and economical practices.

JW's molecular screening process is fully automated, providing simplified and efficient operation. This aspect highlights the company's commitment to offering advanced technological solutions that not only optimize production but also simplify daily operations.

JW offers differentiated Molecular Sieve models, each designed to meet specific requirements:

HLSM-CR Model: Routes the phlegm generated from the regeneration of zeolite vessels to the existing ethanol rectification column in the hydrated ethanol plant. This integrated approach demonstrates improved process efficiency.

HLSM-SR Model: Features its own recycle rectification column, using water vapor as a heat source. This model operates independently and can dehydrate ethanol during the off-season, providing operational flexibility.

HLSM-DE Model: Also features its own recycle rectification column, using anhydrous ethanol vapor as a heat source, reducing water vapor consumption. Like the previous model, it operates independently and can dehydrate ethanol during the off-season, offering improved energy efficiency.
