The design requirement of solids control equipment

In the solids control system design, there are some requirements:

For mud tanks, the effective volume is at least 75% of dimension size.

1). The mud tank should carry capacity of biggest drilling fluid circulation capacity in the drilling process.

2). The mud tank's overall strength should meet the requirement of lifting, transport and density is 2.5 g/ cm3 drilling mud.

3). In the mud tank, between each tank should have connection pipes which contain valves, and upper the mud tank should have overflow mouth.

4). Each cabins should have sand cleaning gates, the gates' down side should on the same level of tank bottom or lower than tank bottom.

5). All the seal parts should resistant to oil, acid, and H2S.

According to SY/T6223-2005, the equipment's choosen as following,

1). Shale shaker's treating capacity should be 100% to 125% of drilling pump's max. flow rate.

2). Degasser: The treating capacity should be 100%-125% of drilling pump's max. flow rate.

3). Desander and Desilter: The treating capacity should be 100% to 125% of drilling pump's max. 
flow rate. And the match Centrifugal pump and motors should meet this capacity requirement.

4). Decanter centrifuge: The capacity of centrifuge usually be 5%-10% of drilling pump's max flow rate.
