The total flow of water ( W) is the sum of W1 and W2. If playback doesnt begin shortly, try restarting your device. In the evaporator, water ( W2) is evaporated, leading to the crystallization of solids ( crystal) and concurrent formation of a saturated mother liquor ( ML) flow. Multiple Effect Evaporator - Mass and Enthalpy Balance. Degree of the mix, pressure across as a limitation and the fluid properties including flow rate, density, and viscosity. The crystal mass flow indicates the part of the solute that has been turned into solid crystals. The number of elements to be mixed at any particular time is considered a function of the particular customers’ need and the system specification requirements. Static mixers that are best suited for specified application can be selected based on the process unit operation that is practised. Pumps and or blower are used to deliver the various components in their ration to be mixed. Static mixers homogenize fluids with no moving parts. There were no previously unidentified potential hazardous events with significant off-site impact determined.Mixers are used for continuous processes where they stir two or more components to achieve the desired product with the required distribution of the makeup components. The actions recorded during the study were mostly in the design or “improved operability and maintainability” categories. Significant issues identified were then recorded in the HAZOP study notes taken during the study process for inclusion in the final version of the updated procedures for the facility. During the study, the safety management system and existing site operating procedures were discussed and included as potential causes for hazardous events and significant operability problems. Therefore, the hazards were generally well-known as well as the required control measures to reduce risk to within limits or acceptable levels as a requirement are made. The group at large had a significant amount of information prior to and experience in the design and operation of mixing section of the plants. Engineering line diagram, control system and equipment design have been updated to reflect the outcome of the HAZOP exercise.
