Oil and Gas

Due to the growing energy demand, cost pressures and environmental sensitivities in the oil and gas industry, this industry has become a highly competitive market.

The oil and gas industry consists of different sectors with different requirements such as production and storage, distribution and transmission and processing of natural gas, as well as a series of general and joint activities in the production and out of oil and gas production, each of which has several challenges. You can overcome these challenges by using industrial automation equipment and instruments.

Iran Electric Sensor Company with more than a few decades of experience in consulting and supplying automation products and precision instruments required by various industries in the country, including the oil and gas industry, is proud to work with prominent brands such as …. ., And …. in solving the above challenges.

The oil and gas industry generally faces the following general challenges:

1. Measuring:

Due to the high financial value of gas transported in large volumes and between two places with long distances (sometimes two different countries) accurate and timely measurement is very important. Sensors and other products and services to measure reliable gas flow It is very convenient.

2. Measuring and evaluating:

Our sensors provide reliable information flow to factory operators, enabling them to control and monitor every part of the process and ensure its accuracy.

3. Quality control:

Throughout the value chain, the quality of raw materials as well as the flow of products must be continuously evaluated. Our solutions use industrial automation equipment and precision instruments to ensure that the required quality level of raw materials, semi-finished products and final products is achieved, and by measuring the total flow composition, the amount of unwanted by-products or before commercial use at all levels. Recognizes.

4. Supervision of publication:

Nowadays, monitoring the emission of pollutants and other substances in the environment is more difficult and more controlled and investigated. Our sensors are good solutions for monitoring the emission of particles and gases, and you can safely trust them.

5. Safety and protection:

The safety and protection of industrial sites and their assets, as well as personnel, is always a top priority. The demand for safety in the oil and gas industry is very high because a catastrophic situation can arise at any time. We provide solutions to identify and prevent explosion hazards and to monitor toxic or corrosive substances in the emission process and vents.

Natural gas is produced from conventional underground or submarine reservoirs, from conventional and unconventional sources associated with hydrocarbon reservoirs such as coal deposits. With new methods such as breaking, gas stored in rock formations is released under high pressure extraction, and floating production storage and loading units or floating power plants have replaced traditional offshore production platforms.

Natural gas, after initial collection and refining, is transported or stored to higher products for use as fuel or further processing.

This process of natural gas production and storage usually faces the following challenges, which we will briefly state its solution:

1. Gas production from coal fissures:

Most of the gas is extracted from unconventional sources such as petroleum ore or coal cracks in distributed wells in a large area. Measuring the volume of each well is critical to maintaining reservoir integrity, managing proper production, and monitoring system equilibrium. To do this, we propose meters that can be embedded near the well and can reliably measure this gas from the source.

2. Measuring flames:

Flammable chimneys exist almost as part of the waste system as a controlled valve for high volumes of combustible gases. The nature, pressure, flow, volume and composition of the gas in a flame chimney can vary considerably over a short period of time. Our ultrasonic gas flow meters are very suitable for accurate process control and measurement.

3. Two-way computational measurement in storage facilities:

Excess inventories extracted for use in seasons when demand peaks and market conditions become more favorable are stored in large wells. Due to the two-way nature of storage (injection and harvesting), ultrasonic gas flow meters, which are inherently two-way and non-mechanical, are an excellent solution.

Oil and gas reservoirs are usually far from consumer markets and require sophisticated transportation systems to distribute and transport. In addition to the accurate transmission of very accurate measurements of volume and quality and the necessary calculations in this value chain, it is very important that it be done immediately.

1. Accurate calculations:

After production and processing, natural gas is transported to the market and sold through high pressure pipelines. Due to the high volume and pressure of the pipes, a small error in the calculation of the transferred volume can cause huge losses to both parties. Therefore, we recommend gas flow meters for fast, accurate and reliable calculations.

2. Measuring at refrigeration temperature:

Natural gas is delivered to consumers through pipelines or through terminals to local distributions at metering stations in urban terminals. In this place, gases are smelled and pressures are adjusted to reach the final consumers. You can use the ultrasonic gas flow meter to perform uninterrupted calculations, non-mechanical measurements, the possibility of installation in almost any piping configuration.

3. Measuring ultrasonic current in distribution networks:

The quick-change module allows you to easily replace magnetic sensors in hydraulic cylinders. As the sensor unit is completely replaced, the hydraulic circuit remains closed. This minimizes the risk of leakage and prevents soil from entering the hydraulic system.

Unprocessed natural gas is usually composed of different percentages of hydrocarbons, sulfur compounds, mercury, water, oxygen and nitrogen. Natural gas refineries must deliver dry and clean natural gas to customers. During this processing, suitable commercial products such as methane, ethane, liquefied petroleum gas, natural gas liquids are produced. This process usually faces the following challenges, the macro solution of which is described below.

1. Enrichment of air oxygen in Klaus process:

Klaus plants process acidic gas from crude natural gas. Acidic gas in these plants undergoes a thermal phase which in hydrogen sulfide is partially burned with sulfur dioxide to form sulfur and primary water. In the next catalytic steps, hydrogen sulfide and sulfur dioxide are converted to sulfur at low temperatures. The challenge for these plants is to enrich the oxygen supply to the air in the class furnace, which allows it to produce acidic gas with less energy and hydrogen in the flue gas treatment. We recommend the use of a robust and reliable oxygen analyzer that monitors the level of oxygen in the combustion air after oxygen injection.

2. Control of natural gas liquefaction process:

If unprocessed natural gas contains high hydrocarbon fractions, liquefied petroleum gas can be recovered as a commercial compound using freezing fractionation processes. If the concentrated liquid contains impurities of sulfur compounds known as mercaptans, it must be sweetened, and in this process the acidic components are extracted with excess air and oxidized to form alkyl disulfides. Our solution to make the desalination process as good as possible is to use gas analyzers to measure the level of oxygen in the excess air in the disulfide separator tank to monitor the oxidation process.

3. Control of Singas production:

Natural gas is often used as the raw material for chemical processes. Syngas is a mixture of H2 and CO produced from methane in a steam modifier. Singas can then be used as the raw material for subsequent processes to produce a variety of suitable commercial products such as methanol, ammonia, LPG and other petrochemicals. To perform the reliable production process of Singas, process gas analyzers are used to monitor the efficiency of methane conversion.

Outside the processing units, there is additional infrastructure and ancillary facilities inside and outside the power site, process heating, gas compression and gas and water purification, etc. for refineries or municipal terminals. These cases also have several challenges such as the following:

1. Monitoring the release of boilers and gas turbines:

Process units of boilers, thermal oxidizers or waste gas burners, compressor stations and other ancillary facilities are considered in the environmental impact assessment. The quantity and type of components monitored and permitted emission limits depend on environmental policy and permits. The choice of a continuous emission monitoring and monitoring solution depends on many parameters, including the type of fuel and its process. You can easily solve these problems with our portfolio of automation products and precision tools.

2. Supervise the processes of inactivation or cover:

Most raw materials and products of the oil and gas industry are flammable due to the presence of oxygen. Explosive atmospheres must be avoided to avoid explosion hazards. This is done by inactivating or covering pipes and storage tanks with inert gases such as nitrogen or CO2. Our laser oxygen transmitter minimizes the consumption of inert gases in a neutralization ring by monitoring the amount of residual oxygen, by sampling and maintaining low gas.

3. Organic residues in treated water or wastewater

In the oil and gas industry, contamination of process water, surface water and wastewater with hydrocarbon compounds is a constant risk. Therefore, the concentration of organic compounds in the water from cooling and heating systems, boilers and water treatment plants is constantly monitored using total organic carbon decomposition systems. We propose solutions for measuring this carbon at the required time and with low maintenance based on UV oxidation or heat that can be used in hazardous areas.
