Product overview
The system based on the comprehensive test and analysis of property
and components of oily sludge, design the airtight oily sludge
extraction separation scheme, including the extraction and
separation units, etc., with Dean - Stark extraction method to
determine the oil content, moisture content and sand ratio of the
oily sludge, determine the best process parameters, operating
parameters and equipment structure parameters, in order to realize
for the recycling of the oil sludge sand. Overcome existing
problems in the existing technology including the huge energy
consumption, low resource recovery rate, easy to cause the
secondary pollution, lack of both economic and environmental
protection and effective processing technology and so on.
Technical route
The separation system consists of pipeline system, power system
(petroleum pump), measuring system (electromagnetic flowmeter,
pressure gauge), PLC control system and the separation system
(separator, buffer tank) five parts. Mixed liquid flow into the
separator for liquid-liquid and solid-liquid separation by its
pressure drop. After separation the crude oil through the oil
outlet into the buffer tank separator, then by the crude oil pump
back to the crude oil pipeline. The purified water isolated from
the separator, by the outlet of the separator to raw water
treatment system. The device has many advantages including the high
oil recovery rate, simple process, short flow, low processing
costs, etc., lead to the oil and solid components of the oil sludge
recycling. Not only protect the environment, reduce the labor
burden, avoid water and soil secondary pollution, has good sludge
processing effect, small investment, cover small area, but also can
be assembled into portable processing device, with high
flexibility, long service life and has a great economic and social
significance.
Industrial design
In oil and gas production, oil and gas well sand production will
continue to deposit in the bottom, the sediment accumulation for a
long time can drown blocking layer of oil and gas, reduce or stop
the oil and gas well production, so the well-flushing sand washing
operation is an important work in oil and gas production process.
In the well sand washing process, the flushing medium (flushing
fluid) injected by the pump injection equipment through borehole,
using the high-speed flow of liquid scatter bottom sand plug, by
virtue of the carrying capacity of the returned flow loop bring
scattered sand out of the ground, for the effective use of flushing
fluid, oil and mud sand need to be separated from flushing fluid
timely, flushing fluid recycle after separation. The system core
equipment is mainly composed of 2 ~ 8 vortex tubes in diameter of
*0 ~ **0 mm, the separation device can maintain high separation
efficiency in the range of rated flow + / - *0%.
Based on different solid-liquid separation processing need, can use
different combination process. Design selection process adopts
recycling sand removal and oil removal two-stage treatment scheme.
This plan is suitable for oily, processing to circulating fluid
purification of oil-water separation, recovery of flushing fluid
can be used to the next flushing process nearby, flushing fluid can
be repeated used.

Product advantage
Multidimensional gradient field coalescence liquid-solid
hydrocyclone separation system has simple process, small equipment
volume, high separation efficiency, airtight process, less flushing
fluid loss and so on many advantages. Can be skid-mounted or
integrated into the single equipment, the process of actual
operation can be attached and fixed to the existing wells washing
equipment. It's can make full use of the fluid pressure of the well
mouth and don't need the additional power plant be in the process
of working. After the separation, the flushing fluid can be reused,
processed sump oil and clay sand can be recycled and disposal
respectively, greatly reduce secondary pollution to the
environment.
