Evaporation Plant - Type of Construction, Arrangement, Operating Mode - Criteria for Selection

While designing the Evaporation Plant, numerous and contradictory requirements have to be taken into consideration. These determine the type of construction chosen and the final arrangement, the resulting process and the economic data. The most important criteria to be considered are:

• Capacity and operational data including quantities, concentrations, temperatures, annual operating hours, change of product, controls, automation, etc.

• Capital and other financial costs

• Choice of material of construction and surface finishes

• Product characteristics including heat sensitivity, viscosity and flow properties, tendency to foaming, fouling and precipitation, boiling behavior, etc.

• Personnel costs for operation and maintenance

• Site conditions such as available space, climate for outdoor sites, connections for energy and product, service platforms, etc.

• Required operating media such as steam, cooling water, electric power, cleaning agents, spare parts, etc.

• Standards and conditions for manufacture, transport, acceptance, etc.

• Legal regulations covering safety, prevention of accidents, sound emissions, environmental protection, etc.

Chem Evaporation Plants are custom designed by highly qualified and experienced design engineers to suit the individual client's requirements, and they have thorough knowledge and skill of the evaporator technology and the problems that can occur. Chem Evaporation Plants have been installed for various applications at more than 100 sites and are performing effectively as per the requirements and design. The above mentioned criteria along with others depending upon the specific project are taken into consideration during the requirement analysis and design stage. Reliability, ease of operation and maintenance are given specific importance for each Evaporation Plant Solution given to the client.

Additional Equipments

• Evaporation Plants are designed as multiple effect systems with vapour recompression. The basic components of these systems are individual evaporation units with interconnecting piping, pumps and other associated equipment. Such additional equipment is necessary for the proper operation - if not provided the required operating conditions, capacity and consumption data cannot be achieved.

• The most important data are pre-heating of the product to be evaporated, condensing of residual vapours and deaeration

• Additional equipment such as heaters, holding vessels, degassers and flash coolers may be required if the properties of the product to be evaporated are to be influenced, stabilized or altered

Sometimes rectification columns for the separation of complex mixtures or aroma recovery or washing columns for the scrubbing of vapours may be required

Supplementary equipment such as cleaning systems, measurement, control and safety equipment, thermal and acoustic insulations are required for reliable, trouble-free operations. Chem designs, manufactures and supplies turnkey plants for various process solutions. Immense experience and expert knowledge of the performance of each individual component enables us to choose the right equipment for each task - this achieves the duty for the entire plant to be satisfied.
