Basic Maintenance Tips to Extend Lifespan of Medical Devices

Hospitals around the globe are having increase in patient inflow. Consequently, there is a rising need for maintaining hospital equipment and providing improved diagnostic facilities. There are various forms of maintenance used in medical facilities, this forms of maintenance falls under two types of maintenance which are; Preventive maintenance and corrective maintenance.

The purpose of preventive maintenance of medical devices is to care and service equipment, by providing systematic inspection, detection for the devices to function in its optimum operating condition, to avoid downtime while corrective maintenance is been achieved with immediate response given to a failed devices when detected. The device is immediately sent down for repairs to avoid more damages to the device.

However, for a piece of medical or diagnostic equipment to live through this period without malfunction, certain maintenance guidelines must be followed.

  • Coordinating service schedules

Numerous devices are been used in medical facilities, for maintenance of these devices to be properly achieved because not all medical assets have the same preventive maintenance needs.  , we have to draw out schedules for the devices, it could be every 3days it all depends to avoid sudden breakdown of devices.

  • Obtaining manufacturer support

There have been situations where medical technicians were not familiar or able to detect the cause or malfunctioning of a device, with this the need to obtain a manufacturer support is necessary to help you in getting your device back to a working condition.

Device data’s or warrant cards of the devices should be kept properly in other to gain access to the manufacturer for repair purpose.

  • Train and retain staffs

Training medical staffs on how to properly maintain medical devices is very key. A staff that is not trained on how to use or operate a medical device could either malfunction the equipment or not be able to use it the way it should.

  • Sterilize, disinfect  and turn off devices when not in use

Devices should properly be taken care off because they are used on patients to avoid transmitting diseases, sterilize and disinfect devices before and after use make sure device is turned off to prolong its life span.

OILFIELD DRILLING CHEMICALS

by

Oilfield drilling is a process of boring hole into to the earth crust for natural gas and oil. To do this, a long bit attached to a “drilling string” is used. The bit varies in diameter from five to 50 inches. After each section is drilled, a steel pipe slightly smaller than the hole diameter is dropped in and often cement is used to fill the gap.This “casing” with cement is used to give some structural integrity to the hole and to isolated high-pressure areas of rock that can explode if allowed to release.

The drilling process can be liken to using a power drill on a piece of wood. The most major difference is that the he hole is filled with “mud” which is often called “drilling mud”. Drilling mud is a mixture of fluids, solids and, chemicals  that lubricate the bit, whose function is to cut away from the drill face, provide a hydrostatic head that counters the pressure of gas or oil, and provide a physical and chemical means of stabilizing and protecting the rock formation that is being drilled.

Drilling muds can be used in a very wide variety of rock formations and conditions, their specific composition varies from site to site, and also with different depths in the same well. Since offshore oil and gas exploration began, many different types of substances have been, and are being, used in the formulation and modification of drilling muds which includes emulsifiers, lubricants, wetting agents, corrosion inhibitors, surfactants, detergent, caustic soda, salts, and organic polymers, (https://vaporblash.com/2019/12/11/oilfield-drilling-fluids-chemicals-market-2019-2026-forecast-oil-and-gas-shale-gas/ ) drilling muds also consist of gelling and deflocculating agents (bentonite clays) filtration control agents, pH and ion-control substances, barites, biocides, lubricants, defoaming agents, and trace elements of heavy metals (such as arsenic, barium, chromium, cadmium, lead, and mercury) which can be retained in the oilfield environment .

Functions of some of the chemicals listed;

  • Clay and stabilizer listed above, reacts with the wells or boreholes water phase of the drilling fluid to improve its stickiness, induce sloughing and increasing its swelling capacity. The stabilizer is designed in a way that it always adheres to the wall surfaces of boreholes and drill cuttings. With this, encapsulation process can effectively seal surfaces and prevent the reactions between the surfaces and the fluid to prevent  undue consequences such as swelling, sticking and sloughing. The aim of this is supposed to boost the stability of the borehole.Eg organophilic clay, bentonite etc.
  • Thinners are also referred to as deflocculants. They are thinning agents used to reduce the extent of viscosity or preventing flocculation. Thinners are often incorrectly referred to as dispersants. However, a thinner tend to come in form of low-molecular weight anionic polymer that functions to neutralize the positive charges accumulated on the clay edges. Good examples of thinners include lignosulfates, polyphosphates etc.
  • Drilling polymers has high molecular weight fluid with the ability to control the well’s fluid loss and to increase the viscosity. There are over four variants of this chemical which can include polyacrylate, Snergistic polymer, polyglycol, XCD polymer or partly hydrolyzed polyacrylamide.

CHEMICALS USED IN THE FLUSHING OF PIPELINES

by

A chemical flush is a process where pressure is applied to empty a pipeline using appropriate chemicals to suspend, disperse and remove accumulated materials. After this process, the pipelines are given a final flush with clean water and chemical inhibitors are added to protect the pipelines.

The reason why chemical flushing is been used today is to remove all dirts , debris, oil, grease, rust, scale, slug, that could be found or formed in the pipelines. These deposits or sometime called fouling, needs to be removed time to time to prevent damage and maintain efficiency of operation .During chemical flushing thin layer of surface of pipe wall will remove as well  as all the unnecessary contamination. Chemical cleaning is preferably used compared to the oil flushing because, chemical flushing will reduce the oil flushing cost in term of flushing time and number of oil flushing materials use such filter elements.

The usual chemical flushing involves

  • Liquid drain opener (alkaline) as first degreaser to remove grease, oils and fat, alkaline opener also dissolves organic residue and cleaning where harder deposits have occurred.
  •  Following this is the liquid drain opener (acid) as second, for neutralizing the caustic remaining on the surfaces of the plant or removing scale build-up. The acidic opener removes mineral deposits in the equipment (especially warm or hot fluid lines).
  •  Rust and scale remover which is used in all operations where rust should be removed and avoided to lengthen pipelines life, efficiency and improve looks of metal pipeline,
  • Neutralization as third stage, rinsing of the pipeline with demineralized water
  • Corrosion inhibitor as final stage. 

During this process temperature and chemical pH level must be carefully monitor and control in order to complete the process with high quality result. Small mistake will cause a lot of problem where the whole process may need to carry out again which not only cost money but time consuming.

Any pipeline, regardless of diameter, requires a large volume of chemicals to be filled and circulated with, to achieve desired results. Special attention has to be paid to the velocity and volume calculations during the pre-engineering phase.

DISPERSANT CHEMICAL

by

Dispersants are chemicals that are sprayed especially on a surface oil slick, to break down the oil into smaller droplets that are distributed or spread over a large volume of water which are more readily mix with the water. Dispersants do not reduce the amount of oil entering the environment, but push the effects of the spill underwater. Dispersant contain compounds such as surfactant that lowers the interfacial tension of molecules with both water-soluble and oil soluble component, which is been used in soap and detergent production.

Dispersant was used in an attempt to clean up the Exxon Valdez oil Spill in the year 1989, though its use was discontinued as there was not enough wave action to mix the dispersant with the oil in the water. Dispersant was also used on the Deepwater Horizon Spill at the Gulf of Mexico in 2010, recorded by The National Academies Press 

CLASSIFICATION OF DISPERSANT

Dispersant are classified according to their generation and types

  • The first generation of products, was similar to industrial cleaners and degreaser which contained components that where highly toxic to aquatic lives. First Generation Dispersants was introduced in the 1960’s and are no longer used in oil spill response
  • Second generation dispersants, also called Type I dispersants, were majorly designed to treat oil spills at the sea by spraying dispersant from a boat. They contain a hydrocarbon solvent with a low or no aromatic content and also 15 to 25% surfactant. These Generation dispersants are intended to be applied undiluted
  • Third generation dispersants contain a blend of two or more surfactants with glycol and light petroleum distillate solvents. The most common surfactants used are non-ionic and anionic. The concentration of surfactant with the solvent lies between 25% and 65% and tends to be higher than the second generation/ Type I products.

TYPES OF DISPERSANT

1) Conventional Type

The conventional type of dispersants are the mixture of non-aromatic hydrocarbons solvents & mostly used for shoreline clean up. They are used undiluted at the time of application, and the quantity of dosage of this type of dispersant is kept between the range of 30-100% / oil spill quantity.

2) Concentrate Type

A concentrated dispersant is more popular because it is much easier to handle and deal with concentrated products. This dispersant consists of the mixture of oxygenates like glycol and non-aromatic hydrocarbon.

They can be used after diluting, but the latest concentrated dispersants (3rd generation) can be used undiluted from the ship as well as from aircrafts. The dosage of concentrated dispersants drastically reduces to 5-15 % of dispersant/oil quantity

Other Application of Dispersant.

Surface coating

In order to provide optimal performance, pigment particles must act independently of each other in the coating film and therefore must remain well dispersed throughout manufacture, storage, application, and film formation. Unfortunately, colloidal dispersions such as the pigment dispersions in liquid coatings are naturally unstable, and they must be stabilized against the flocculation that might occur.

Bio-dispersing

Dispersants are used to prevent formation of biofouling in industrial processes. It is also possible to disperse bacteria slime and increase the efficiency of biocides

Concrete

Dispersants are used in the mixing of sand, stone, cement and water to diminish the use of water and still exhibit the same slump (flow) property. This makes the concrete stronger and more resistant to water penetration.

Detergents

Dispersing is the major goal in the use of detergent, which the liquid bath is water. Detergents also are used as emulsifier in some applications. Laundry detergents eliminate dirt and grime, which naturally disperse.

Automotive

Automotive engine oil contain both detergents and dispersants. Metallic-based detergents prevent the accumulation of varnish like deposits on the cylinder walls,they also neutralize acids. Dispersants maintain contaminants in suspension.

Dispersants are also added to gasoline to  prevent the buildup of sticky residues

Gypsum wallboard

A dispersant is added to the gypsum wallboard slurry to reduce the amount of water used. The lower water usage allows lower energy use to dry the wallboard.

Process industry

In the process industry, dispersing agents are added to process liquids to prevent unwanted deposit by keeping them finely dispersed.

Oil drilling

In oil drilling, dispersants aid in breaking up solid or liquid into fine particles or droplets into another water medium.

Factors that Determine the Quantity of Dispersant used are;

Type of oil in the spilled surface

Quantity of oil

Time the oil spill incident happened

Distance from the shore

Weather Condition

Marine environments and marine organism in the area of oil spill

Advantages of using Dispersant

  • They can be used in stronger current and in rough seas; it removes the water from the surface, and reduces contamination of water birds and marine animals.
  • It stops the carryover of oil by the wind to the shoreline and beaches.
  • It is one of the quickest methods in fighting oil spillage. It restricts the formation of an oil-water emulsion.
  • Dispersion does not produce wastes to be disposed.
  • When dispersed, the pollutant is no longer drifted by the wind, and then follows the stream; therefore, when carried out upwind sensitive areas, dispersion contributes to reduce the amount of pollutant which would drift towards these locations.
