At MCC zeolite is used as a desiccant, so the composition of the spent zeolite, unlike the
original, will be characterized by a high content of water. Spent zeolites are solid pellets
from gray to brown, not flammable and not toxic. Possibly deposited in the open air. Spent
molecular sieves (zeolites waste) are absent in the existing list of toxic waste to be taken
into account. Spent zeolites should be stored in landfills to recycling. One way of disposal is
to use them as a component of building material, for which the company needs to conduct
laboratory tests and certification for its quality.
Multimodal zeolite and coal waste
In some molecular sieve adsorbers loading is carried out in layers with other fillers,
resulting in the discharge of a mixture of spent adsorbents.
Multimodal departure of the zeolite, and coal produced in swing absorbers (PSA)
ethylene plant. The processed mixture of zeolite and coal will be a solid waste black and
gray. Their properties will be blend of non-toxic, a fire hazard.
Possible storage in landfills to recycling. Method of disposal is determined by the
company after the laboratory studies and a certificate for its quality.
The spent silica gel
Formed by replacing the silica gel in the adsorber polyethylene plant.
For the year produced a few tons of spent silica gel. Material differs from the original
high moisture content. Non-toxic, no fire hazard. Adverse impact has the dust. Discharging
through a special hose in a container with a lid.
A mixture of silica and zeolite
Is formed by replacing the desiccant in the adsorbers polyethylene plant. As a filler
used silica - 66.7%, and molecular sieves - 33,3%. Silica gel is a white granular powder,
odorless density of 640 kg/m3. The molecular sieves used different types of zeolites.
Zeolites are white, gray or yellowish-brown balls, odorless density of 750 kg/m3.
The spent adsorbent is removed for disposal or storage. One way of disposal is to use
it as a component of a building material for which the company needs to conduct laboratory
tests and certification for its use. It is also possible disposal option.
Spent Alumina
Formed in plastic adsorbers installation in the absorption of chelates of activated
alumina. Spent alumina will be a spherical granules white or grayish-white color. As part
may be small amounts of substances adsorbed from the air. Non-toxic, no fire hazard.
Unloading is carried out through a special hose in a container with a lid.
Plastic Waste
Presented in the form of plastic chips, or film. Plastic chips are formed in some areas
of the polyethylene plant. Consists of 91 wt. % Polyethylene and 9 wt. % Water. The
process of collecting periodic.
