Environmental Improvement Plan (EIP)

Our Environmental Permits

Our policy is to do better in the standards set by the national environmental regulations covering the operation of our plants. In doing so, our policy is to measure, manage and minimize the environmental impact of our operations. Our environmental performance initiatives include:

Environmental Improvement Plan (EIP)

Orpic has an overriding commitment to environmental responsibility and this has always been one of our foremost priorities.

A number of key projects were identified in 2011 to eliminate or reduce negative impacts on the environment. An Environmental Improvement Plan was developed in co-operation with the Suhar Environmental Unit (SEU) branch of the Ministry of Environmental and Climate Affairs (MECA).

19 Projects were identified at an estimated cost of USD 50 million, of which 65% have been completed to date. The 19 projects have been grouped under five of key adverse environmental impacts, namely:

  • Waste Water Treatment and Odour Nuisance
  • Flare Emissions Reduction
  • SOx Emissions Reduction
  • Fugitive Emissions Reduction through LDAR (Leak Detection and Repair) Program
  • Industrial Waste Management

Environmental improvements in 2013:



As part of the EIP our Gas Flaring has reduced by 60% since 2010

Another EIP adverse impact area, SOx emissions, has been reduced by 80% since 2012

We opened an Industrial Waste Storage Facility within our Suhar complex

The following measures are also under the level set by MECA:

Measurement and monitoring

For all the stationary sources in all our plants we monitor Sox, Nox PM10 & CO

For the ambient air quantity we monitor PM10, NOx, Sox, CO, O3, Hydrocarbons, Methane, Non methane hydrocarbons

We measure the ambient air quality for various contaminants on a frequent basis

As part of this process we meet regularly with the Ministry of Environment and Climate Affairs (MECA) and its Suhar Environmental Unit (SEU), usually between 1-4 times a month.

Products

In support of the national objective to provide clean fuels in Oman, our refineries started producing environment-friendly unleaded motor gasoline in 2001 and eco-friendly ultra-low sulphur diesel in 2004.

Liquid effluents

Our waste water treatment facilities are designed to meet marine discharge standards (MD159/2005), in some of these facilities; we reused the treated effluent for irrigation purposes.

Our Sour Water Stripping Units ensure the removal of pollutants such as hydrogen sulphur and ammonia, to make the water suitable for re-use in the refining process.

Any liquid effluent is checked for compliance against pollution parameters as stipulated by the Ministry of Environment and Climate Affairs before it is discharged.

The waste water is treated and meets to a large extent the standards imposed by MECA

The following measures are also under the level set by MECA:

  • Chemical Oxygen Demand (COD)
  • Biological Oxygen Demand (BOD)
  • Total Suspended Solids (TSS)
  • Oils and Phenols




Gaseous emissions

We use low sulphur, hydrogen-rich fuel in furnaces to reduce emissions.

We have in place continuous ambient air monitoring to check and ensure good air quality around the refineries and plants.

We have installed low NOx (oxide of nitrogen) burners in our new heaters to reduce emissions.

Our steam-assisted smokeless flare ensures the safe disposal of gases from or plants during emergency situations.

Solid waste

Precious metal bearing catalysts are sent for metal recovery for re-use.

Spent alumina (RFCC spent catalyst) is exported for re-use in other industries.
