SOLIDS CONTROL POEM

I am in the business of solids control equipment and solids control system.

Although equipment is cold, I’d like to bring life to the equipment as I am a vividly woman with a lot of hobbies, music, dance, swimming, tennis, etc.

Sometimes, I share some poem with foreigner, except for trading, I’d like to share Chinese culture with customers in different industries, oil and gas drilling, horizontal directional drilling, TBM, CBM drilling, etc.

POEM NAME:
The Charms of Niannu

POET: Shushi (Year 1083, when he was in 46, he wrote this poet. And he is the famous poet in our history for his bold and his heroic style)

*****
The waves of the mighty river flowing eastward
Have swept away the brilliant figures of a thousand generations.
West of the old fortress,
So people say, is Lord Zhou’s Red Cliff in the time of the Three Kingdoms.
The tumbling rocks thrust into the air;
The roaring surges dash upon the shore,
Rolling into a thousand drifts of snow.
The River and the mountains make a vivid picture—
What a host of heroes once were!

And I recall the young Lord then,
Newly married to the fair younger Qiao,
His valorous features shown forth;
With a feather fan and a silken cap
Amid talking and laughing he put his enemy’s ships to ashes and smoke.
While my thoughts wander in the country of old,
Romantic persons might smile at my early grey hair.
Ah, life is but like a dream;
With a cup of wine, let me yet pour a libation to the moon on the river.

Dewatering unit

Brightway Dewatering Unit includes a contained automatic flocculation unit with pumps, polymer preparation tank and mixing system. Dewatering system uses coagulant and flocculants chemicals including Poly Aluminum Chloride( PAC) and Poly Electrolyte(Polymer) to coagulate and flocculate the solids in the fluid and make the slurry in a condition that centrifuge can separate the solids from the mixture more convenient. Cuttings generated in the dewatering system are discharged by the centrifuge in the corral; liquid is discharge straight to one of the buffer tanks.

The Dewatering suction lines could be connected to middle mud pit and all ES tanks.

The gathered waste water in the waste pit or the amount of the mud which the mud engineer wants to dump ( usually at the end of drilling sections) should be transferred to the ES tanks or the mud pit and from there could be processed by dewatering system.
The overall objective of dewatering systems is to process drilling waste. Typical applications are:
 Reduction of the liquid waste volume generated
 Recycling back into the active fluids system
 Disposal
 Release in an environmentally safe and cost effective manner.

The main aim is to reduce well costs, either through a reduction in fluid volume used during the well, and /or through a reduction in disposal costs.
Dewatering systems have become major factors towards “closing the loop” in the dry location or zero discharge concept. The displaced or excess drilling mud along with the excess location liquids produced on the dry or zero discharge location are channeled to the collection pit and placed in the storage system. The dewatering system is utilized to process the liquid waste from the active mud and the storage system. The cleaned effluent from the dewatering system can then be :
1) Returned to the active mud system
2) Returned to the drill water tanks for use as dilution
3) Treated further to acceptable regulatory standards for release to the environment

SEPARATION PLANT COMPARISON BETWEEN BRIGHWAY BWTBM425 AND ITE TSP300-2

Long time not update the Blog regularly, need to catch up, : )

Today we compare the separation plant between Brightway BWTBM425 and ITE TSP300-2.

Let’s see ITE TSP300-2 firstly, and I like ITE description about their separation plant, quite brief and fresh.

The ITE TSP300-2 is a compact separation plant and specially designed for processing of slurries and removal of drilled solids from the slurry circuit in tunneling, horizontal drillings or deep hole drilling applications.
The TSP300-2 is composed of two 4-panel vibration screening machines, two 15” hydro-vacuum-cycones, one 20’ process tank with one integrated centrifugal feed pump, one control cabinet and accessories.
Adjustable discharge chutes, fold-away platform and pluggable railing for safe working and good access provide a plug-and-play solution. Assembly time is therefore reduced to a minimum. Feeding of shakers and cyclones is accomplished by an integrated fixed piping and wiring system in a minimal footprint.
Instead of a collection of equipment from various sources, the ITE TSP300-2 is a field-proven network of separation components specifically designed to function as a single unit. During each separation stage, a maximum of solids particles are remove from the slurry. The modular system guarantees continuous and fast advance rates, reducing downtimes of a minimum. The innovative screening technology combined with hydrocylones constitutes a complete recycling concept, providing optional removal of critical fine particles down to 45 microns and guaranteeing the constant slurry properties.
The vibration screening machines can be equipped with a wide range of different ITE hookstrip and panel screens which are available from 4mm mesh width down to 45um.
