Solid wastes generated by process industries usually include chemical residues, precipitated sludge of various kinds, spent catalysts and various other waste products resulting from the specific production cycle. Treatment technologies vary from incineration to composting, while a partial recovery is usually possible for heavy metals. A significant effort is presently under way at the R&D centres to improve the recovery and reuse of solid wastes.

Waste water treatment systems serve the twofold purpose of complying with the local environmental regulations concerning wastewater and recovering the highest possible amount of treated water. There are several processes that can be used to treat wastewater, depending on the type and extent of contamination and the quality targets of the effluent and recycled water. Based on our in-depth knowledge of industrial processes and familiarity with the various types of treatment processes, at Energeco we can identify the optimum solution for any wastewater problem.

The flare's purpose is  to burn all flammable gases released from pressure vessels, thus avoiding their release into the atmosphere. However, a flare is only the terminal section of a blow-down system, which must be designed for the reasonably predictable worst-case emissions scenario. The emissions, thermal radiation, odours and noise associated with flaring should also be taken into account and minimized. Furthermore, several studies indicate that, in certain circumstances, flares did not burn waste gas as efficiently as previously believed.

The last phase of the production cycle frequently involves the market placing of the products: in this case, a finishing process is usually required. This may involve weighing, filling, capping, labelling, palletizing, etc. Typical example, in the case of oil products, are LPG bottling, lube oil blending and packaging, asphalt drum filling etc. Several filling methods are available based on weight, level, volume or flow control: each method has its specific advantages and disadvantages, depending on product characteristics such as hazard, viscosity, density, temperature, etc.

Product storage and shipment are the final stages of the production cycle. Products are generally shipped by means of trucks, barges, rail or dedicated pipelines, according to product characteristics and site location. Solid products may be stored outdoors in open yards or inside warehouses and filled in bags, or reclaimed and shipped in bulk.

Storage Systems for Chemical, Pharmaceutical, Food Industry and, in general, for non-Oil&Gas Plants, often involve the use of a range of special construction materials, such as Stainless Steel, special alloys, HDPE, fibreglass or epoxy-coated or glass-lined tanks, of special pumps such as magnetic driven pumps, as well as tailored control systems.

Refinery storage systems involve, in particular, large-scale crude oil tanks and a considerable number of both intermediate and final product tanks. Economy and safety aspects require an optimized design, and a proper and accurate implementation of subject alarm and emergency systems. The expansion or change of use of some tanks should be considered and the  original design principles taken into account.

Any industrial plant requires the storage of large quantities of raw materials, for processing, and final products, for shipping. Furthermore, it is also necessary to store intermediate products from front-end process units, to be utilized as feed for the next units. Quantities are always significant, especially in the case of oil refineries, where the storage of strategic stocks should be taken into account according to local regulations.
