Many industries worldwide use chemicals to perform a wide variety of tasks. In fact, chemical consumers range from a typical homekeeper who purchases basic cleaning supplies to multi-national energy producers who require customized chemicals for the various stages of energy production.Hydraulic control valves Historically, these larger chemical users have purchased chemicals in bulk. Thus, the chemical companies that supply these industries with chemicals have made the various chemical blends in large batches.

These larger chemical users often desire thousands of different blended chemicals. For example, oil refineries use custom-blended corrosion inhibitors in their processing plants to provide maximum corrosion protection for prolonging the life of the processing plants. Therefore, a chemical company may be required to stock hundreds of different intermediate chemicals, concentrates, or solvents, in order to produce these blended chemicals.

A typical device for blending chemicals includes a large vat capable of holding in excess of ten thousand pounds of chemicals. Water Pump Control ValvesLarge agitators are placed inside the vat to mix the chemicals that are added to the vat. A plurality of lines feed chemicals into the vat. One end of a line is coupled to the vat, and the other end of the line is coupled to a container holding a chemical to be added to the mix. Pumps, coupled to the lines, draw the chemicals through the lines from the containers to the vat. The amount of chemicals added to the vat is controlled by mass flow meters, which are connected to the lines, or by determining the weight of the chemicals added to the vat.

Once the large batch of chemicals has been thoroughly mixed in the vat, a sample is removed and taken to a laboratory for testing. The testing may vary depending on the type of blended chemical desired. However, typical testing may include measuring the density of the blended chemical or taking the FTIR fingerprint of the chemical. If the blended chemical passes the test, it is packaged into appropriate containers and shipped to the customer. If not, the blended chemical must be further tested to determine the percentages of the individual chemicals which comprise the blended chemical.API CAST STEEL VALVES Then, it must be determined how the blended chemical can be reworked in order to produce the desired blend. Finally, the proper amounts of additional chemicals must be added to the blend to achieve the desired blend. Once reworked, the blended chemical may be packaged and shipped to the customer.
