Aluminum Smelter Industry by Limult

Aluminum smelting is the process of extracting aluminum from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.

Although abundant in the earth's crust, pure aluminum is virtually impossible to find. Until the development of the Hall-Héroult process, the available quantities of pure aluminum amounted to samples. The Hall-Héroult process enabled the mass production of aluminum. In 1888, Hall founded the first industrial smelting operation, and global production has grown ever since.

By eliminating the risk in hazardous waste materials, transforming it into valuable products with assured market offtakes, aluminum smelter waste materials such as spent potlining, butt shot-blast fines and high-sodium anode butts, can be considered as valuable mineral resources, if treated properly. If the hazards in the materials are removed while retaining the valuable chemicals and minerals, the materials can be used for beneficial energy savings and lower greenhouse gas emissions in cement manufacture.

Limult Group realises this value proposition by:

  • transforming hazardous waste materials into valuable products that are safe to handle and use in other industries
  • delivering products and technical support to established markets
  • providing certification for regulatory compliance and chain of custody control.

Limult provides a fully sustainable solution for SPL recovery and re-use with no residual waste material.

By maximizing the value of these materials, Limult provides the smelter with the lowest cost option for responsible management of residual materials.

Nigeria Industrial Revival By Limult

Nigeria presents considerable
potential to return high yields on investment in manufacturing segments. While
the discovery of hydrocarbons and rising crude prices created a dependence on
export receipts and tax revenues and marginalized industry’s development, the
crash of the global oil market in 2014 helped to refocus public policy on
economic diversification and non-oil industries. A series of recent policy
documents have set ambitious goals for sector development and outlined
discrete, actionable strategies to match those ends. Critically, the
administration has introduced a range of incentives to launch and broaden
activities in various manufacturing segments, including agro-processing,
biofuels, cement and automobiles. Although manufacturers have struggled
recently with currency volatility, a chronic foreign exchange (forex)
shortfall, and gaps in water, transport and electricity distribution systems,
these incentives, as well as a planned surge in public spending on
infrastructure, should help to accelerate investment and growth across a range
of industrial activities.

Limult Group has made so much
great impact in the revival of industrial development in Nigeria through the outstanding
services they provide in the Agro sector, oil and gas sector and in the
construction industry.

Thermal power Station Construction by Limult

Intelligent thermal power plant concept

With the upgrading of productivity, the complexity and dynamics of business activities and the ability to gradually exceed the capabilities of human analysis and optimization, it is necessary to rely on intelligent technology instead of humans for process management, data analysis, decision optimization, and the core goal is to achieve intelligent production activities. The high degree of unity allows the system to work together.

Intelligent thermal Power Plants value and Goals

 In this theoretical context, intelligent thermal power plants have the following three values and goals. First, intelligently realizes the potential hidden danger display of the device, enabling it to operate more efficiently and sustainably. Second, let the machine replace humans and assist the staff to carry out thermal power plant management and operation and maintenance. Third, the production and operation process of the power plant will be more transparent and synergistic, making the management process more flexible and effective. Focusing on the above objectives, the construction of intelligent power plants needs to focus on the three-dimensional dimensions of intelligent sensing, intelligent control and intelligent management.

The big data analysis generated by coal-fired power generation in
thermal power plants is used as a clue to deeply explore the value of data to
create more benefits. To this end, according to the latest definition of the
industry, it can be concluded that the intelligent thermal power plant is based
on modern digital information processing and communication technology, and
integrates technologies such as intelligent sensing, control, management and
execution to achieve synergy with the smart grid. A highly efficient, safe and
environmentally friendly thermal power plant.

At Limult we develop
new, unique construction methods for the installation of major equipment in
thermal power stations, namely boilers, turbines, and generators.

Hydro-Electric Power Station Construction by Limult

Hydroelectric power station

In hydroelectric power station the kinetic energy developed due to gravity in a falling water from higher to lower head is utilised to rotate a turbine to produce electricity. The potential energy stored in the water at upper water level will release as kinetic energy when it falls to the lower water level. This turbine rotates when the following water strikes the turbine blades. To achieve a head difference of water, hydroelectric electric power station are generally constructed in hilly areas. In the way of the river in hilly areas, an artificial dam is constructed to create required water head. From this dam water is allowed to fall toward downstream in a controlled way to turbine blades. As a result, the turbine rotates due to the water force applied to its blades and hence the alternator rotates since the turbine shaft is coupled with alternator shaft.

The main advantage

An electrical power plant does not require any fuel. It only requires water head which is naturally available after the construction of the required dam.

No fuel means no fuel cost, no combustion, no generation of flue gases, and no pollution in the atmosphere. Due to the absence of fuel combustion, the hydroelectric power plant itself is very neat and clean. In addition to that, it does not produce any pollution to the atmosphere. Also from constructional point of view, it is simpler than any thermal and nuclear power plant.
The constructional cost of a hydroelectric power plant maybe higher than that of other conventional thermal power plants because of construction of a huge dam across the flowing river. The engineering cost in addition to the constructional cost is also high in a hydroelectric power plant. Another disadvantage of this plant is that it cannot be constructed anywhere according to the load centres.
So, long transmission lines are required to transmit the generated power to the load centres.

Limult is a
leader in the design of hydroelectric power plants, with years of experience in
the design and development of these projects. Limult has participated in feasibility studies, preliminary and
tender design, procurement and/or the construction management for major

Electricity Generation in Nigeria by Limult

Nigeria is endowed with large oil,
gas, hydro and solar resources, and it has the potential to generate 12,522 MW
of electric power from existing plants. On most days, however, it is only able
to dispatch around 4,000 MW, which is insufficient for a country of over 195
million people. Power Africa technical support to distribution companies in
Nigeria helped them increase revenue by over $250 million - money that can be
reinvested into the distribution network, improving service and expanding
access. The Nigerian power sector experiences many broad challenges related to
electricity policy enforcement, regulatory uncertainty, gas supply,
transmission system constraints, and major power sector planning shortfalls
that have kept the sector from reaching commercial viability.

Electric Demand and Electrification rate

Nigeria has an electrification rate of 45% and despite this relatively low figure in conjunction with the significant issues undermining power supply in the country, demand for electricity keeps increasing. In 2015, power supply in Nigeria averaged 3.1 GW, which was estimated to be only a third of the country’s minimum demand, with many consumers forced to rely on privately owned generators.

Causes of Failure in the Electrical distribution In Nigeria

The factors include inconsistent and misguided power reform policies; inefficiency in power generation, transmission, distribution and consumption;
and the incompetent work force of the energy companies.

Having stated the above problems of electrical
distribution in Nigeria, Limult Group is presently leading the path of
sustainable and 24/7 uninterrupted power supply to the above mentioned problems
which are;

  • Solving barriers in the gas-to power value chain: this is done by launching a federal coordination mechanism covering gas supplies, generation, transmission and distribution.
  • Plan for renewable energy integration: complete development of the 14 planned solar plants.
  • Investing in new grid infrastructure to facilitate integration of intermitted source.
  •  Integrate mini-grids into DisCo networks to supply power to underserved areas.

Liquefied Natural Gas Plant by Limult

The earth has enormous quantities of
natural gas, but much of it is in areas far from where the gas is needed. To
move this cleaner-burning fuel across oceans, natural gas must be converted
into liquefied natural gas (LNG), a process called liquefaction.

What is LNG –
liquefied natural gas?

is natural gas that has been cooled to –260° F (–162° C), changing it from a
gas into a liquid that is 1/600th of its original volume. This reduction in volume enables the gas to be transported
economically over long distances.

Liquefaction plants

 LNG liquefaction plants are generally
classified as baseload or peak shaving, depending on their purpose and size.
The process for the liquefaction of natural gas is essentially the same as that
used in modern domestic refrigerators, but on a massive scale. A refrigerant
gas is compressed, cooled, condensed, and let down in pressure through a valve
that reduces its temperature by the Joule-Thomson effect. The refrigerant gas
is then used to cool the feed gas. The temperature of the feed gas is
eventually reduced to −161°C, the temperature at which methane, the main constituent
of natural gas, liquefies. At this temperature, all the other hydrocarbons in
the natural gas will also be in liquid form. In the LNG process, constituents
of the natural gas (propane, ethane, and methane) are typically used as
refrigerants either individually or as a mixture. Feed pretreatment and
refrigerant component recovery are normally included in the LNG liquefaction
facility. LPG and condensate may be recovered as byproducts.

How do we use

LNG is returned to a
gaseous state at LNG import and regasification terminals around the world. Once
it has been warmed to become natural gas, it is dispersed through pipelines for
use by homes and businesses. It can be used in a variety of ways: Residential
uses for natural gas include cooking, heating homes and generating electricity,
while commercial uses for natural gas include heating, generating electricity,
manufacturing products like fertilizers, paints and medicines, and occasionally
fueling commercial vehicles.
