How to purify the tank bottom sludge with pyrolysis method?

Tank bottom sludge typically consists of a mixture of hydrocarbons, water, sand, rust, and other contaminants that accumulate at the bottom of oil storage tanks over time. Purifying tank bottom sludge using pyrolysis is an effective treatment method that can convert tank bottom sludge into valuable fuel oil, solid carbon, and gas. Here is how to operate a pyrolysis unit to recover this type of sludge.

Process of DOING tank bottom sludge pyrolysis machine

1. Pre-treatment of tank bottom sludge

Dewatering: Reduce the moisture content in the tank bottom sludge through mechanical means such as centrifugation or filtration.

Size Reduction: If necessary, break down larger pieces of solid material within the tank bottom sludge to increase the surface area exposed to heat.

2. Pyrolysis Process

The core of the purification process involves heating the tank bottom sludge in the absence of oxygen (or with limited oxygen) to decompose it into different fractions:

Heating: The waste tank bottom sludge is fed into a pyrolysis reactor where it is heated to temperatures typically ranging from 400°C to 600°C. This temperature range facilitates the breakdown of complex hydrocarbon chains into simpler molecules.

Pyrolysis Oil: Liquid fraction containing various hydrocarbons, which can be further refined or used as fuel for heavy oil generators, boiler heating, gypsum plants, glass plants, brick plants, steel plants, cement plants.

Char/Carbon Residue: Solid residue left after pyrolysis, which may contain metals and other non-combustible materials. This residue can sometimes be reused in construction or must be disposed of appropriately.

Gas: Non-condensable gases produced during pyrolysis, often used to power the pyrolysis reactor itself or for other energy needs.
