Solvent Recovery System for Processing Industry

Solvent recovery systems are widely used in recycling and waste reduction in the packaging industry. To distil the liquid and remove the solvent from the water, a solvent recovery system uses a heating part and a condensation component. A vacuum unit can be used in solvent recovery systems, allowing the device to run at temperatures below the boiling point of the solvent. Alaqua Inc is a supplier of processing equipment as well as a service provider for all kinds of processing equipment. A distillation procedure  is used to recycle solvents that involve the following steps:

  • On a batch or continuous basis, a distillation vessel conducts waste solvent solution.
  • By conductive thermal transfer, a heated jacket injects heat into the waste solvent.
  • The vessel may be worked under a vacuum, lowering the solvent’s boiling point.
  • The surplus fluid transforms from a liquid to a vapour as it exceeds its boiling point.
  • A condenser with both a condensing and a sub-cooling portion collects the sterile solvent vapour. The solution is converted back to a liquid in the condenser and cooled to room temperature.
  • The pollutants do not go into a vapour phase and instead remain in the drain port to be discharged.

Benefits of Solvent Recovery Systems

Some of the major benefits of Solvent Recovery Systems are as follows:

  • Allowing producers to reuse recovered chemicals reduces raw material and solvent costs, as well as chemical transportation and storage costs.
  • Since fewer solvents and additives are disposed of, there are fewer EPA monitoring standards and risks.
  • Continued production quality with the use of reclaimed chemicals, which are just as available and efficient as fresh chemicals once they’ve been restored.


Solvent Recovery at Pharmaceutical and Chemical Production Plants

When assessing a pharmaceutical, chemical, petrochemical, or medical device manufacturing facility’s overall performance and profitability, the recovery and reuse of solvents used in processing processes is a critical factor. Organic solvent recovery and reuse have two advantages: it eliminates waste and lowers chemical prices. One of the most popular techniques used in a solvent recovery application is distillation.

The concentration/recovery of residual medicinal substance from the column discharge stream comes second to the recovery of solvents with distillation technology. The traditional approach for facilitating higher recovery rates of the medicinal product is to use evaporation technology after the column.

How Solvents are Recycled and recovered?

Contaminated solvents or mixtures of chemical compounds are heated using heat transfer media (thermal oil, hot water, steam) and brought to a boil using AlaquaInc Environmental’s solvent recycling equipment. The gases that originate from the distillation process are then liquefied and cooled in the cooler by condensation.

Thermal decomposition can occur during the distillation of critical chemical materials. The gentle method of vacuum distillation, which is done at low pressure, is used to avoid this, as well as to minimise energy demand (and thereby lower running costs) (vacuum).

The boiling point of the liquids to be isolated is lowered as a result of the vacuum, as is the likelihood of foaming, and the components evaporate at a much lower temperature than at standard pressure.

Different Utilizations of Spray Dryers – Alaqua Inc

cooling crystallizers

The spray dryer is a processing device used for drying the substances while utilizing a spray. The spray dryer mixes a heated gas with an atomized (sprayed) liquid stream within a vessel (drying chamber) to achieve evaporation and produce a free-flowing dry powder with a controlled average particle size that can further be converted into solid form as well. We are a spray dryer supplier based in the USA, along with spray dryers we also supply other processing equipment worldwide.

Some major components of spray dryer unit operation include a method for atomizing a solution or slurry; a source of hot air or an air/gas heater such as a waste flue gas; for achieving the heat and mass transfer a gas/spray mixing chamber with adequate residence time and droplet trajectory distance; a resource for recovering the solids from the gas stream; a fan to induce the required air/gas through the spray drying system. The surface area per unit weight is generated by the atomization of the liquid feed which is also a unique feature of the spray dryers.

To understand the process of spray drying, it is majorly conducted in four separate stages: the atomization of the feed; spray-air contact; drying; separation of the dried product from the drying air.

Major utilization of spray dryers are for food processing and pharmaceutical industries, as well as for ceramic materials,  creating paint pigments, catalyst supports, and also for the use with microalgae. Spray drying is also very commonly used for the technical processes to dry organic or aqueous solutions, suspension, dispersion, and emulsion in industrial chemistry and the food industry.

Spray drying is one of the oldest equipment or technique that has been evolved and developed over several decades from the 1870s to the 1900s period. The first spray dryer used the nozzle atomizers with rotary atomizers that were introduced several years later. The first major commercial use of the spray dryer was milk drying. It gained its popularity during the second world war to decrease the weight of transportation of food and other materials.

The spray dryer is most commonly used in the pharmaceutical industries for medicines and food industries to dry the liquid into a powder form and then convert that powder into a solid form if required. It is widely used in the food industry for dairy products and the dairy industries have very wide use of spray dryers to dry milk, cheese, and various other dairy products. Milk is concentrated in the falling film evaporator before spraying as the amount of liquid that an evaporator can evaporate is 1/10 than the amount of liquid a spray dryer can dry. Spray Dryers are also used for egg products, food and plant products such as instant coffee powders, edible plant protein, fruits and vegetable products, carbohydrate and similar products, yeast products, cellulose products, slaughterhouse products, fish products, pharmaceutical products, etc. The spray dryer is used in all these industries for drying the liquid into a powder or solid form. for more details please visit our Site - https://www.alaquainc.com/

heat exchanger optimization design can be understood at three levels ?

The heat exchanger is a device used to transfer the heat from one medium to another. The heat exchangers are not only used to heat but majorly are used for cooling the substances and are used by the processing industries to transfer the heat. The exchanger separates the substances by a solid wall so that they can be prevented from mixing. It is majorly used by the wastewater treatment industry, refrigeration systems, wine-brewery industries, and petroleum industries.

The main features of heat exchangers are flow configuration, construction method, heat transfer mechanism. We are the heat exchanger equipment supplier to meet the different processing industrial requirements. We make sure to meet the industrial requirements for all the machinery, whether it’s an evaporator, crystallizer, or any other processing machinery. We are capable of providing the utmost trustable heat exchanger available as we are the heat exchanger maker and hence are the most suitable option to meet our customer’s processing requirements.

The heat exchanger optimization design can be understood at three levels are first, to identify the heat exchanger that can meet the process specifications at the lowest primary cost; secondly, to identify the heat exchanger that operates with satisfactory over the lifetime of a plant with process specifications; and, thirdly, to identify heat exchanger and auxiliary elements to meet process specification with the minimum total amount for the process that includes utility cost and lost production.

Meeting process specification means that the heat exchanger should be capable of desired changes if required so in the thermal conditions of the process streams within the acceptable pressure drops. It should be able to bear any kind of mechanical pressure of transport, manufacturing, installation, operating under normal and powerful conditions that could be emergency forced to shut down and during maintenance, and should be capable of lesser effects during fouling and corrosion. It should be sufficiently flexible to make required changes in process conditions in service stream temperatures such as normal fouling transients, diurnal and seasonal changes. The heat exchanger must be able to support with minimum downtime during cleaning, repair, or replacement of short-lived substances such as tubes and gaskets. Considering all these points, the heat exchanger should be as less costly as possible.

In retrofit applications, the heat exchanger might need to meet certain special requirements such as weight, diameter, length, or inventory standards. There could be certain special requirements during manufacturing or the capacity and experience of the maintenance and operating personnel.
