Mainly the data related with the process is described fully. 4.1
Material Handled It is the feeding fluid to the bag filter. If there are multiple materials, their analytical method is needed. Each the component of raw materials is expressed as %WT or % VOL. If the space is not enough, mark the Remark No. at the blank and describe at the below remarks space.
4.2
Density (Bulk/Real) For transportation of raw material, generally bulk density is needed. But the bag filter is to separate the mixed particles, the bulk and real density both are specified.
4.3
Viscosity In case of attachable materials, they are classified. But for reference, it is specified.
4.4
Temperature It means the temperature feeding to the bag filter. If materials are not handled at the prior process, it can be specified as ambient temperature.
4.5
Moisture Content It means the fluid's containing moisture contents, is necessary to the filter design.
4.6
Particle Content

It means the particle contents in feeding fluid to bag filters. As it is related with the design, it should be specified. 4.7
Particle Size Distribution If there are various sizes in the feeding fluid, its distribution is specified by size. If the particle distribution is uneven, it is noted as %WT or %VOL. In that case, remarks no is noted and it is noted below remark space in detail.
4.8
Angle of Repose It means the angle of the repose, used hopper volume design mainly. It is necessary or referable according to the kinds of the equipments. Here, it is to be used to the hopper design at the bottom of the casing in the back filter.
4.9
Particle Size (to be removed) It means the size to be eliminated. Must consider the environmental regulation.
4.10
Dust loading (to be removed) It means the dust contents filtered in the bag filter. So it can be contents in the fluid.
4.11
Pressure Drop (Max. available) It is about 100 mmH2O at the operating condition because of pressure drop at the filter.
4.12
Flow rate

It means the ability and capacity of handling; the capacity is showed at the normal and design item on the data sheet. The normal item must be described. Design capacity can be the rated capacity in the equipment detail design and motor power calculation to vender. 4.13
Suction and Discharge Pressure They are the inlet and outlet pressures of the bag filter respectively. The discharge pressure is normally ATM.
4.14
Operating Type Operating type is composed of continuous or intermittent and auto start/stop or manual start/stop as showed on the data sheet. If the special operating type, it is noted on the remark space. Whether start/stop type is automatic or manual, it is necessary to confirm the supply of start/stop push button box. For all equipments at the start of project, it is necessary that the determination between form each vendor and from instrument engineering team. If automatic, it is necessary to confirm the needs of remote switch on the local push button box. If continuous on-off operation, it is noted in the remarks space. (For example, on-off cycle time: 3min.)
4.15
Operating Time It is expressed as operating cycle, means the operating time per day. It is related with the plant operating time of client. If 2-shift, it is 16Hr/day. If 3-shift, it is 24Hr/day.
4.16
Material Properties It means the chemical and physical properties of the transported

material as an engineering view. It is good to select the related property on the data sheet. If there is need to express the power of property, select it and it is reasonable to mark the high or severe at the blank. If multiple properties, select and mark multiple options. If no listed properties, select other option, and describe it. 4.17
Installation It means the construction location of equipments on the lay out, either indoor or outdoor. If extra condition like under roof, make a note.
5. CONSTRUCTIONS It shows the equipment structure and specification. Only process options are marked, the others are marked by vendor. 5.1
Design Pressure and Temperature Because the bag filter only removing the dust equipped on the hopper is contacted with atm., design pressure is not considerable. But if it is equipped in the process, the temperature and pressure are to be considered.
5.2
Corrosion Allowance The casing of the bag filter is mainly carbon steel, so corrosive allowance should be considered.
5.3
Thickness It means the thickness of casing fixed up by vendor.

5.4
Connections The type and size of the connections between suction and discharge of body are specified.
5.5
Filtering Area It means the surface area of filter where the fluid goes through, and based on vendor standard.
5.6
Filter If the type of filter options is fixed, the others of filter options are specified by vendor.
5.7
Bag Cleaning Method If the filter is operated for a long time, the dust is attached to the filter surface. So, after the power is removed, the filter can be used continuously. If continuous operation, the air jet pulse type is applicable, and if intermittent operation, the motor shaking type is applicable.
5.8
Dust Removal Method It means the method the remove the dust pile up at the bottom of the filter.
5.9
Cycle Time It means the air pulse cycle or shaking cycle, and is fixed up by vendor.

Insulation If necessary, fix up the whether insulation is needed or not.
5.11
Overall Size and Weight It is informed by vendor.
6
MATERIALS It is general that the materials are fixed according to the properties of the raw material and the operating purpose. The material contacted with raw material on process should be specified. After at least, the material of the filter and casing are fixed up, the others are fixed up by vendor. The selection of the materials is fixed by referring the material properties on operating condition.
7
DRIVER If normal, supplied-by/mounted-by is fixed by vendor. Because the things with drivers are fixed by other detail associating teams, the driver needs not to be fixed by process engineering team. So no. needs no. marks.
8
ACCESSORIES Because the supply scope of accessories is related with the supply scope of the equipments and fixed up according to operation/system. it can fixed up at the process data description possibly. They are specified if fully explainable as process requirements and special requirements. So, it is possible that the detail associated teams select them. 8.1
