The Management of Waste

 
The wastes are products at all stages of the production of oil and gas. An effective program of waste management:
• identifies and characterizes all the waste products
• follows the waste from their generation until their elimination
• identifies the waste to problem
• reduces the production of waste and find innovative solutions to manage the waste in a way more efficient and profitable
• minimizes the potential for impacts on the environment or the health and safety or the waste management practices inappropriate.
The Potential Problems
The wastes which are not stored, treated and disposed of in accordance with regulatory requirements and practices of industrial standard acceptable could:
• Cause a contamination of soil and groundwater
• represent a risk to the health and safety of workers
• Having for result a significant responsibility for the company and its senior executives and employees
• Increase significantly the costs of operations, waste treatment and disposal and for the restoration of the site.
The Practices This section describes:
• The methods of controlling the production of waste(c-to-d, reduce, reuse, recycle and recover) .
• The general steps for the management of waste (c-to-d, of the characterisation until the elimination)
• The practices for the handling and disposal of the specific waste streams
The Control of production of waste
The most effective way to control the waste is to avoid their production in the first place. Strategy is the most widely accepted to control the waste is to reduce, reuse, recycle or retrieve the products before they become waste
Reduce
Acquire, chemicals in bulk in order to reduce the waste of container and the frequency of spills. Use the storage in bulk in order to eliminate the waste of container and reduce the risk of a spill of the multiple containers of treatment.
Select drilling technology available the more efficiently to reduce the requirements for fuels, lubricants and spare parts that could become waste (ex, a equipment turning point with minimum requirements of lubrication (lubricant)).
Prevent leaks and spills in order protect the soil from any contamination. Ensure that the storage facilities are equipped with an adequate protection against alteration due to the climatic conditions in order to reduce the losses (ex, alteration, leakage) which requires (request) a cleaning and a elimination.
Train (cause) and motivate employees to practice the reduction of waste. Also provide the recommendations of employment and training to employees to ensure the optimal use of chemicals.
If that is possible, use the non-hazardous materials in place of the hazardous materials. To review also the need for each product used to ensure that it is not simply added to the production of waste. Improve the practices for receipt, storage and handling of materials (materials) in order to reduce the losses.
Take the provisions for analysis in a laboratory of the oils of emptying of compressor and gear to determine if a oil change is required. Take into consideration the use a minimum of toilet washing encased with tanks of retention in order to reduce the consumption of water and the size of the tank.
Re-use
Make sure you have obtained the approvals (permissions) appropriate before re-use any material (material) or hydrocarbons. The examples of what can be re-used include:
• The waste oil and lubricating oils of the box to speed after having been recycled
• containers (ex, the barrels and buckets), which can be rendered (returned) to suppliers
• The oily rags, which can be cleaned
• The filters reusable
• The spent acid, which can be used to neutralize the caustic waste
Recycle 
waste that cannot be reduced or reused. Recycle the lubricating oils, the glycol, solvents, chemicals inuses, batteries, paper, metal, plastic containers and glass.
Take into consideration the storage facility in bulk to pick up sufficient volumes of waste in order to perform batch transfers for recycling facilities (ex, the lubricating oil). Evaluate the waste stream in order to identify the sources of fuel or the basic products or raw materials for use by other operators or industries (ex, paraffin wax).
Participate in the great efforts of industrial recycling which indicate the flow of industrial waste to companies interested in acquiring the waste.
Restore (recover)
restore wastes that contain substances that can be reused, for example:
• Separate and recover the oil from water from the washing
• Filter the lubricating oil and lubricating oils of the spiral in order to extend the period of their reuse
• Incorporate the reduction measures and restraint of the spill in the design of all the facilities for loading and unloading of liquids (ex, the box of purge on connections outside of the truck)
The General Management of Waste 
which follows is the recommendations of a identification, treatment, storage, transportation and disposal effective waste.
The characterization of waste
The characterization of waste involves the evaluation and documentation of the physical properties, chemical and toxicological characteristics of waste.
In order to determine the characteristics, take into consideration how the waste is generated and, if it is necessary, obtain a sample and perform its analysis in a laboratory. In order to reduce the costs of analysis:
• Focus the analysis on the properties of a potential concern regarding the waste tested
• Run or lead a program of tests detailed if the characteristics of the wastes are not well defined
• We must not mix the waste once they are characterized
The classification of waste
before to eliminate the products of waste, it is classifying them according to their physical and chemical characteristics. The following recommendations will help you to classify the waste flows from an oil field.
The identification of waste
 identify the waste as being:
• Of hazardous waste or non-hazardous from an oil field
• a dangerous goods
• a chemical product commercial deters
. The commercial goods dangerous which are separated from the waste are considered hazardous wastes of the oilfield if they demonstrate always of dangerous properties (ex, flammability, toxicity or corrosion).
• The container (containing) empty that previously contained of commercial chemicals.
• a mixture of waste classes. Classify a load of waste mixtures as being the most hazardous wastes if the individual quantities are not known.
The Hazardous Waste from an oil field
waste could have a variety of properties with consequences varied concerning security and the environment. The following properties have been identified as creative of special concerns:
• The flammability
• The potential for spontaneous combustion
• The incompatibility of water
• The potential for oxidation
• The toxicity
• corrosion
• The contents diphenyl polyvinyl • The toxicity lixiviante
The mixed wastes Unusual and the Unknown waste
if the wastes are an unusual mix and the dangerous properties cannot be predicted with certainty, analysis the waste as follows.
• Determine if the dangers manifested all hazardous properties. • If the wastes are not found in any of the lists mentioned above, or if the dangerous properties are otherwise unknown, analyze a representative sample of the waste the properties which could be reasonably expected to be found. • Determine if the waste surplus the criteria cited in Table 2 of the Users Guide to Alberta for managers of waste (the Protection of The Environment of Alberta
1995).
Once the waste material has been sampled and analyzed, we must not mix up the waste with the other materials that change or alter the specific properties for which the waste material has undergone an analysis.
Measure the volume of waste use of counters, the gauges of tanks or ladders to toggle (balance tilting) when it is possible to measure the volume of waste. Estimate the volumes, based on the size of the container or containing waste.
Use a centrifuge to determine the proportion of the hydrocarbon, strong products and water when the mixtures are eliminated. Declare all the waste from an oil field in tonnes or cubic meters.
The Storage and Handling of waste
The waste from an oil field stored, are non-hazardous or hazardous, in one of three locations:
• In a storage area at the level of the installation of gas and oil approved by the regulatory body appropriate
• At the level of the installation of waste storage site (autonomous) operated by an oil and gas company for the collection of its own waste.
• At the level of the transfer station operated by an independent company as a third party collector of waste.
