A Steam Jet Thermocompressor is an energy saving device that compresses low pressure steam, often waste steam, to a higher usable pressure. It offers an advantage over mechanical compressors/blowers due to its smaller size while handling a very large vapour volume under vacuum conditions. Due to its size and absence of mechanical parts, it requires a very low capital investment and offers a very long maintenance free service with operational safety.

Chem Process’ Forced Circulation Evaporators are normally used for liquids which are prone to fouling, scaling, crystallizing or for those which are inversely soluble or while concentrating thermally de-gradable materials. Here high re-circulation rate allows high liquor velocities through the tubes which help to minimize the buildup of deposits or crystals along the heating surface. The universal type, preferably used for concentration of solutions containing encrusting substances, hardening agents and un-dissolved solids, and for viscose solutions; also suitable for evaporative crystallization.

Steam Jet-Liquid Jet Ejector Combination Systems are ideal to handle small quantities of non-condensable gases and large quantities of condensable vapors on intermittent or batch processes. Low level mounted and energy conserving with effective scrubbing of outlet gases, offers the advantage over other systems in producing vacuum and simultaneously scrubbing entrained gases before discharging to the atmosphere, making it an ideal selection for contaminated and/or corrosive applications. They are available in multi-element form as a central vacuum source on multi-purpose process applications.

Liquid Jet Ejectors are specially designed to operate using water, solvent or any other clear liquid and generate vacuum corresponding to the vapor pressure of the liquid. They are very useful for applications when expensive process fluid is to be recovered. They are most suitable for low non-condensable and high condensable loads in applications like distillation and evaporation. External heat exchanger can be provided to maintain liquid temperature in accordance with vacuum requirement. For higher vacuum, liquid jet ejector can be utilized along with a steam jet ejector combination system. The whole system can be supplied as a pre-assembled skid mounted unit for quick installation.

The Falling Film Evaporators can be operated with a low temperature difference and since the product residence time is very less, they are best suited for liquids which are temperature sensitive, have a high rate of specific heat transfer, particularly for non-crystalline solutions. Having low liquid holding volumes, the falling film evaporators are very easy to operate, clean and are extremely sturdy, thus the most frequently used types

Chem Process’ Rising Film Evaporators operate on a “Thermo-Siphon” principle. Feed product enters the bottom of the heating tubes and as it heats, steam begins to form. The upward force of this steam produced during the boiling causes liquid and vapors to flow upwards in parallel flow. At the same time the production of vapor increases and the product is pressed as a thin film on the walls of the tubes, and the liquid rises upwards

Our Adiabatic Vacuum Continuous Crystallizers operate on the principle of ‘adiabatic boiling’ wherein the feed liquor is exposed to high vacuum resulting in evaporation and cooling of the liquor.

Chem Process’ Spray Evaporator Crystallizer is a direct contact heat and mass transfer system which works similar to the principle of the induced draft cooling tower. These are for specific purpose sort of crystallization units and stand apart due to their unique operational philosophy, often referred as the granulation and prilling process. These type of crystallizers are generally utilized in the fertilizer segments where the most important aspect of this process is to lower the moisture content and improve the flow-ability of the very fine submicron particles.
