Process Electric Heaters are designed for heating flowing liquids and gases. It can heat air, nitrogen, steam, water, oil, and chemicals. It consists of a tubular flanged immersion heater mounted in heating chamber. The chamber is equipped with flanged inlet and outlet connections, mounting studs, high temperature insulation and an aluminum jacket.

Process flow diagram is a diagram, which is commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Typically, process flow diagrams of a single unit process will include the following process piping, major equipment items, control valves and other major valves, connections with other systems, major bypass and recirculation streams.

Process flow sheet is a deinking technology that is utilized in the production of newsprint from recycled fibres is well established. Major factors that influence this technology development and process design include: product quality requirements, resource availability, wastepaper characteristics, percent of recycled fibre in furnish and environmental regulations. This sheet provides details on the devices to be used, operating temperatures and pressures at key locations, compositions of flow streams, utilities, feed and product stream details, and other important data.
