In order to meet the chemical and physical changes generated inside the closed circuits of industrial plants (i.e. boilers, furnaces, etc ...) the use of plants for dosing of chemical additives is necessary. In this regard, it is a series of components - tanks, injection and transfer pumps, mixers, valves, gauges, etc. - that managed with a logic indicated by the customer or developed by us, inject substances such as ammonia, hydrazine, phosphate, ... in the contemplated quantities and arrangements. At the same time we also produce plants for "Drinking Water", with items similar to those mentioned above, that, with the aid of special filters, purify water entering the system according to the specific. The industrial chemical processes can be represented in different ways, for example with a simple process diagram (where the equipment and the current main materials are represented) or with a Piping & Instrumentation Diagram (where all the equipment and control instrumentation are highlighted). The Process Flow Diagram, or PFD flow sheet is a diagram commonly used in chemical and process engineering to indicate the general pattern of plant processes and equipment. In this sense, the scheme of the process appears to be the first step in designing a plant, followed by the energy and mass balance to proceed with the mechanical scheme. The PFD shows the relationships among the main equipments (or drive) where the chemical process occurs, without taking into account several details, such as the piping detailed structure and many ancillary equipments. The purpose of the PFD is therefore to give an idea of the process that takes place in a plant or in a section of it, without claiming to be comprehensive.

Generally, a Process Flow Diagram related to a single chemical process may include:

• piping main lines
• major equipment
• control valves and other main valves
• connecting lines with other systems
• bypass and main recirculation lines
• stream identification and useful data for their characterization (temperature, pressure, flow, density, etc ...)
• number of pipe line
• control equipment (such as sensors and actuators)
• secondary bypass lines
• shutoff valves
• drain valves and drain lines
• safety valves and check valves
• flanges

We list below some of the most common types of equipment we manufacture.

• Chemical Dosing Skids
• Demineralization Skids - DEMI
• Water Treatment Plant
• Drinking Water System
• Air Extraction System
• Driven-Heating Fuels Plant
