In general, the typical sources of waste sludge oil sands are as follows: 1) Waste sludge oil sands produced by crude oil tank cleaning 2) Waste sludge oil sands of refineries 3) Drilling waste oil sands. What are the characteristics and hazards of these oil sands?

 

(1) Characteristics of oil sludge:

Its physicochemical properties are very complex, generally containing aged crude oil, waxy, asphaltenes, colloids and solid suspended solids, bacteria, parasites, salts, acid gases, corrosion products; a small amount of mechanical impurities, heavy metals and salts; Benzene, phenols, strontium, barium and other odorous toxic substances and a small amount of radioactive elements. Water treatment agents such as flocculants, corrosion inhibitors, scale inhibitors and fungicides are added in the production process; as well as oil-containing weak acid low-temperature binders, polyacrylamide sulfides and sulfonated mud systems, etc., which are extremely difficult to separate and treat.

(2) Hazardous performance:

When the volatile components enter the sky, the total hydrocarbon concentration of the air quality exceeds the standard; after entering the soil, it will cause damage to the microbial and soil plant ecosystems; after entering the water body, it will destroy the surface water and groundwater ecosystem; the harmful substances in the crude oil have Mutagenicity and carcinogenicity can cause serious damage to human health.

 

Oil sand separation system

GN solid control cooperated with professional customers and launched the skid-mounted oil sand separation system to solve the problem of oil sand separation. The separation solid control system is a more advanced, stable and reliable, safe and environmentally friendly treatment method, which can fully meet the requirements of field environmental operation conditions; the social value of the environmental protection industry, the economic value of resource recycling and reuse, and the market application prospects. Looking at it, it has great practical significance!

The main equipment involves centrifuges, Shale Shakers, chemical dosing equipment

The GN solid-control oil-based cuttings disposal system consists of a collection and transmission device, a drying treatment device, a centrifugal separation device and other auxiliary devices. The system as a whole has sufficient rigidity and stability, and the system equipment runs reliably. The processing system is composed of the GNLW453C-VFD large-speed high-speed centrifuge and the GNCD930D high-speed cuttings dryer.

The main principle of action:

1. The cuttings removed by the solid-phase control equipment such as the vibrating screen, desilting and de-sluicing device, centrifuge, etc. of the drilling machine solid control system are collected by the collecting and conveying device and transported to the screw conveyor of the dryer feeding.

 

2. The cuttings are sent to the dryer in a spiral to carry out solid-liquid separation and drying, and the liquid is discharged into the drain tank of the dryer. The solid phase is spirally conveyed to the cuttings box through the discharge port. When the liquid level of the draining tank of the dryer reaches the warning position, the centrifugal separation device is automatically started to carry out the fine recycling treatment of the aunt.

 

3. The solids discharged from the centrifuge are collected through the outer discharge of the slag discharge tank, and the clean mud discharged by the centrifuge is discharged into the clear liquid recovery bin. When the liquid phase in the recovery bin reaches the warning position, the drilling is continued through the external transportation of the conveying device. jobs.

The GN solid-controlled oil-based cuttings non-landing treatment system has the following advantages:

1. The overall armoring design of the system is convenient for installation and transportation. The armoring can be hoisted and transported without disassembly.
2. The working speed of the dryer can reach 900~1200r/min. 3. The working speed of the centrifuge is 3000r/min, and the length-to-diameter ratio of the conversion is 3.42. The oil industry has a large aspect ratio design.
3. The system can realize the automatic automatic operation without liquid automatic discharge. The personnel only need to pay attention to the working state of the dryer and the centrifuge.

5, can adapt to 50% solid content, 2.2g / cm3 high density above the oil-based cuttings processing, and can reach continuous 24 hours continuous working state.
