It include: feasibility studies for energy saving and purity improvements of final products; column simulations and design; pilot plant testing; plant optimization; installation or supervision; start-up work; staff training; guaranty service.

Distillation Colum Revamping

Reduce your column high at 2.0 times and energy consumption at 30 % with Maleta Trays. Distillation Column Revamping

➤ Modern requirements to the distillation process are more stringent energy consumption and the quality of the final products. Many of existing distillation column being revamped to more efficiency that gives opportunities to have energy saving, improvement of product quality and increase of product yield.  Some of columns should be absolutely revamped for new one and some of them can be change column internals. In case of revamping column internals/trays we can use existing installation, heat exchangers, condensers, reboilers, tanks, pumps and others instrumentation. Column revamps need individual approach and should goes step-by-step.

➤ Maleta cyclic distillation LLC is propose to revamping your column internals to high efficiency Maleta trays. As results you will have: reduce column high at 1.5 … 2.0 times; reduce energy consumption at 20… 30 %; improvement of product quality; increase of product yield. Innovation design of trays provides simpler and faster revamping and more stability operation. 

 
➤ Our services are included: plant audit, simulation and optimization; pilot plant testing feasibility studies; individual solutions; process integration; design and manufacturing of Maleta distillation trays; installation; start-up; staff training; guarantied and post-guaranteed service.

Thank you for visiting our booth and lecture at ACHEMA 2015

✹ From 15-th to 19-th June 2015 - Frankfurt am Main, Germany our company pass exhibition stand at Groups Research and Innovation at ACHEMA 2015.

➽ It was our pleasure and honor and we enjoyed many inspiring conversations. We have been impressed by the number of visitors and the great interest in our cyclic distillation technology, especially for operation principle and technological benefits of our system. By Dr. Bogdan Maleta held a lecture at section Energy Efficient Processes - “Open new opportunities of distillation columns through cyclic distillation technology”. 

➽ At our booth at ACHEMA 2015 we presented cyclic distillation column (cold stand) that have has 5 distillation trays. It was demonstrated key technological benefits of our cyclic distillation like: reduction of the residence time of liquid in the column; the uniform arrangement of liquid on the tray; ability to control the amount of liquid on the tray; placement any type of packing between trays for rise mass transfer efficiency. 

➽ Partition bubbling layer on height; the pressure drop in the column does not depend from change liquid load in the column, since the amount of liquid on the trays is constant; and others.  If you have further questions or you wish more information about our technology and services, please feel free to

Maleta cyclic distillation LLC has presentation stand at the ACHEMA 2015 - Hall 9.2 Stand D76

From 15-th to 19-th June 2015 - Frankfurt am Main, Germany our company at Exhibition Groups Research and Innovation has presentation stand with cyclic distillation column.  We invitation you visit our stand and get acquainted with all benefits of Cyclic Distillation Technology: lower investment cost; lower hot energy consumption; lower electricity energy consumption; improvement of product quality; increase of product yield.

Pilot Plant Testing of Distillation Process

Our industry-pilot distillation system is available for testing feed stocks in temperature range from 50°C to 320°C in vacuum, atmosphere and pressure for absorption, distillation and reactive distillation. On the basis of these tests we get the full scale design, products quality and yield.  All these results are guarantees for a future successful project implementation.  As results of co-operation with our team you will get most efficiency and profitable solution for your project. 

Our pilot distillation column has 21 trays with column diameter 325mm. Power 60 KW. The pressure range is 5kPa - 1MPa. Liquid flow range is 0.2 – 1 m3/hr. Operation modes are: stripping column; stripping column without selection of the bottom liquid; rectification part of column; rectification column at infinite reflux Ratio (R=∞). 

The high level of competition in business gives a high rate of improvement of production processes with a constant increasing of the quality of the products and reducing of their costs. The leadership position in the market could be provided by permanent scientific research development.

Turning the Fuel Grade Ethanol into Food Grade Ethanol via Cyclic Distillation Columns

Today for fuel grade ethanol plant with big capacity there is a cost effective solution - the part of plant capacity converted to production of ethanol food grade. For fuel grade ethanol plant that uses as raw materials wheat/corn our company proposes technology solution in turning the fuel grade ethanol into food grade ethanol. We are doing audit of existing fuel grade ethanol plant and adapted our technology to the current production and customer requirements. To turning the fuel grade ethanol production into food grade ethanol is necessary adding additional distillation columns in distillation department.

Cyclic Distillation Columns

For cleaning ethanol from impurities we will use innovation technology of cyclic distillation. This innovation confirms by patens of USA, Europe, Russia and others countries. Mass transfer efficiency of cyclic distillation in 2…3 time height that classical distillation. The number of distillation tray in 2…3 less that classical.

Maleta cyclic distillation LLC has great experience in production high quality ethanol food grade. The main indicators of quality are organoleptic and physical chemical properties. In production high quality ethanol food grade we use many of know-how and highly effective distillation columns.

Distillation Trays + Structured Packing Enable to Partition Bubbling Layer on Height and Increase Efficiency

Tray column and  packed column widespread use in chemical, petrochemical and other industries to separate liquid mixtures. Today, high efficiency of mass transfer is one of key factors influencing the choice of column type. Our company proposes additional increasing mass transfer efficiency by placement structured packing between distillation trays.

Most efficient using of the structured packing is achieved in a flooded her condition, in the mode of emulsification. In this case, increases the mass transfer area and the volumetric mass transfer coefficient is 2-3 times. Cyclic distillation technology is able to raise efficiency of mass transfer due to the location structured packing between the Maleta trays. For cyclic distillation there is no fluid motion at the tray, as result we have effect of partitioning the bubble layer by height.

Technological advantages: 

·        Possibility to set structured packing between the trays (including a fluidized  layer);

·        The increase in the volume mass transfer coefficient is 2-3 times;

·        Partition bubbling layer on height. 

Cyclic distillation technology gives opportunities to combine all the advantages of tray and  packed column.
