Make more profit by improving your electrical power quality

Make more profit by improving your electrical power quality

  Electricity is the main driving force of industries today. The reason behind it is electricity can be easily converted to other forms of energy, regardless of the industrial types electricity is used all over the world in industrial sectors. Poor power quality in the industry will cost money in the form of equipment damage, production loss, raw material loss, greater down time and goodwill loss. To survive the today’s global competitive market productivity is the key.  Thinking about the basic inputs to production—time, labor, and materials it is very much clear that there isn’t much room for optimization. Power efficiency is definitely the sector where industry can focus to mitigate losses such as down time, production loss and equipment damage. There is a wise saying “If you can measure it, you can manage it”. So it’s time to break down “Power Quality” term to its sub-sectors for better understanding so that you can measure each of the problematic parameters in your facility...

How to get Environmental Clearance Certificate in Bangladesh

How to get Environmental Clearance Certificate in Bangladesh

  Environment, is a term that encompasses all living and non-living things occurring naturally on Earth or some region thereof. Environment plays an important role in the healthy living of human beings. Humanity's entire life support system depends on the well-being of all the environmental factors. But, there is drastic environmental change due to industrialization and excessive pollution. So, we must ensure sustainable development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Keeping this in mind, Ministry of Environment and Forest of Government of the People’s Republic of Bangladesh made few rules which is known as Environment Conservation rules which classifies industries in four categories in consideration of their site and impact on the environment. All of existing industrial units and projects and proposed units and projects must get Environment clearance certificate to continue business in Bangladesh. There are so many advantages of having that certificate like, It meets the legal...

Save Energy through Lighting System

Save Energy through Lighting System

  We are living in a world where energy, in a medium of fuel, is very much limited and the bad news is we have already consumed a bigger portion of it. With the help of new technologies and inventions day by day, the world is moving towards the renewable energy from non-renewable energy.Hence, we have to use the non-renewable energy intelligently to take the maximum output from this limited resource. Nowadays by dint of media revolution and awareness, most of the people are familiar with the term “energy saving” or “electricity saving” but they don’t have the proper knowledge and skill about it. One of the reasons is most of them are a non-technical person or being in another technical field which is not relevant to the energy saving concept. Whenever it comes to the question of energy saving our subconscious mind tells “it is a big issue and I have no role on it”, “Energy savings can only be done...

Air conditioning system efficiency – Part 2

Air conditioning system efficiency – Part 2

  In previous article, we discussed about the importance of energy efficient cooling system. We mentioned about energy saving measures that can be applied in a chiller plant and discussed some of them briefly. Today we will continue our discussion on measures to save energy from a chiller plant and also for individual AC unit. Condenser and evaporator heat transfer efficiency The heat transfer efficiency of evaporator, condenser and condenser heat rejection equipment decreases as a result of fouling. This leads to reduced capacity and increased energy consumption. So, measures should be taken to maintain heat transfer efficiency by improving maintenance performance to reduce fouling. Condenser tube watersides, evaporator tube watersides need to clean on a regular basis. Cooling water need to be tested and treated on a continuous basis. On a wet cooling system, bleed rate need to be adjusted to maintain proper water conditions with minimum water consumption. Where possible, automatic monitoring and cleaning system can be installed to reduce the...

Air conditioning system efficiency – Part 1

Air conditioning system efficiency – Part 1

  Air-conditioning systems used in industrial, commercial and institutional buildings can account for a large fraction of the total electricity consumed. In Bangladesh where the climate is warm and humid for 9-10 months in a year, cooling and dehumidifying may account for more than 50 percent of a facility’s energy cost. Therefore, it is important to understand how cooling systems work so that they can be installed and operated as efficiently as possible. Many improved technology made it possible to build new facilities with improved energy efficiency. There are also many techniques available to improve the efficiency of existing air-conditioning system. These range from simple adjustments which pay back quickly to expensive retrofitting. Air conditioning system can be divided into two groups: Central air conditioning system (chiller) and individual AC unit. Measures to save energy in air conditioning system include but not limited to: Selection of best system from various options Chiller efficiency and life cycle cost Optimum operating temperature Sizing...

Risk Quantification – A Scenario Based Approach Utilized in Natural Gas,LPG and Petrochemical Industries

Risk Quantification – A Scenario Based Approach Utilized in Natural Gas,LPG and Petrochemical Industries

Syed Quarishy, Technical Safety and Risk Management Consultant   Risk is often defined as a function of the likelihood that a specified undesired event will occur and the severity of the consequences of the event. Risk is derived from the product of likelihood and potential consequence. Risk in general is a measure of potential economic loss or human injury in terms of the probability of the loss or injury occurring and magnitude of the loss or injury if it occurs. Risk thus comprises of two variables: magnitude of consequences and the probability of occurrence. Quantitative Risk Assessment (QRA) is a dominant analysis tool used for risk management and safety improvement. It provides a rational basis for evaluating process safety with respect to its theoretical and practical limitations. QRA should be used when the available input data are sufficient enough to ensure that valid and robust results will be obtained. To provide results consistent with good industry practice Risk Management Guidelines are often used to...
