Harpers delivers a tank cleaning methodology that’s tailormade to each vessel or tank - changing the industry standard as well as enhanced mechanical cleaning.

All sizes of tanks and storage vessels can be cleaned with our customised, and engineered approach. With our expert knowledge in confined space and non-entry cleaning, Harpers ensures your tanks are safely cleaned on time and on budget.

Harpers Energy’s proprietary tank cleaning process enables tank cleaning in a chemical closed loop environment. First, we custom engineer a solution that liquefies the sludge deposits in your tank that would normally be removed mechanically. Then we apply the selective chemical solution with a cutter stock and extract the content using engineered circulation process. Lastly, the tank is degassed chemically, resulting in a superior level of surface and air cleanliness. And it can all be done without the entry of people.

Benefits of non entry vessel cleaning:

Slashing Disposal Costs: With our chemical tank cleaning process, organic solids are dissolved inside the tank, letting you avoid expensive hazardous waste disposal expenses.
Shortened Cleaning Duration: Faster scheduling means less down time so that your plant can get back to operational capacity.
Recycle Hydrocarbon Product: Rather than creating waste for disposal, recycle it using our specialized solvent cutter. Take this opportunity to generate revenue rather than creating costs.
Environmental Performance: Our advanced chemical tank cleaning process also minimizes waste, leaving only insoluble, non-hazardous materials for disposal.
Safety Performance: Our chemical tank cleaning methodology reduces or eliminates the requirement of personnel to enter the tank; work is performed in a closed loop system.

All units are equipped with modern safety advancements – back up cameras and alarm as an extra precaution. These industry leading units have exceptional vacuum recovery which gives them the capability of loading all industry products. This is to provide you, the client, with the most advanced, safety designed equipment for any of your service work.

Harpers provides modern vacuum trucks which are suitable for your onsite, day-to-day operations such as fluid transfers, spill clean ups, rig work, septic services and all your vacuum needs.

Our vacuum units are a tri-axle truck with a fully integrated combined pump and tank unit that is specifically designed for the oil and gas industry. This truck provides the easiest solution for the removal of any liquid or liquid and particle mixture from tanks and other equipment. It has a compact design, which offers a small on-site footprint, and in addition to its many safety features, it is designed to be easy, safe, and efficient to operate.

Our diesel-powered vacuum trucks use liquid ring pumps to provide the vacuum which typically operate at speeds up to 700 rpm, providing approximately 8,000 cfm airflow at high vacuum levels. The tank on the truck can hold 15,000 litres of liquid at temperatures ranging from -29˚C to 93˚C. When using these pumps, flammable vapours may accumulate on top of the product separator. Vacuum pump vapours are controlled through safe vapour recovery and venting methods. The truck also has an integrated emergency shut off system to avoid “dieseling,” which occurs when flammable vapours enter the air intake of the diesel engine.

Our High airflow vacuum services have a multitude of applications from spill mitigation to hazardous and non hazardous waste disposal, to sewer maintenance and cleaning and interceptor pit cleaning.

Fouling components and rust gradually form during operational processes that will eventually require removal. Our high-pressure washing equipment is designed for various industrial applications that will leave equipment surfaces free of deposits and rust.

Our high-pressure pumps are rated for 15,000 psig with capabilities ranging up to 40,000 psig when used with engineered adapter settings. Each pump can be used interchangeably with adaptable parts such as dump guns and rotating nozzles to address all cleaning requirements.

New Generation Tube Lancing Equipment

While old generation tube lancing heavily relies on manual labor to clean tube one at a time, Harpers employs second-generation high-pressure lancing technology (XLTC) which provides a number of benefits:

Multi-Tube Cleaning Capabilities: to increase productivity and reduce duration;
Remote Controlled Technology: allowing for operators to clean the tubes from a location that is not in the line of fire for safer execution
Flex Tubing: which allows the lance to easily navigate complex tubes such as U-bends
Versatile Equipment Assembly: the TLX can be used in conjunction with pumps at different pressure settings and sizes to address varying tube diameters, configurations and deposit characteristics.
Spool and piping hydromilling
Heat exchanger tube lancing
Heat exchanger bundle blasting
Tray cleaning
Tank internal washing

Chemical cleaning is applicable to a wide range of applications from new construction to ongoing maintenance activities.

Post operations equipment may accumulate sludge or suffer significant corrosion during use which can result in fluid obstruction, affecting heat transfer ability, high concentrations of contaminants such as LELs (low explosive limits) or H2S and more. Harpers utilizes our low Pressure Chemical Cleaning Skids in numerous applications with a combination of our selective chemistries and engineered programs to meet all of your challenges.

Chemical cleaning methods:

Through our years of experience using a range of chemical providers, we have determined our chemicals to be the superior provider in the market. Our chemistries specialize in degassing and decontamination, which address LEL’s, H2S, pyrophoric scale, naturally occurring radioactive material (NORM), heavy hydrocarbons, grease, and odours.

For heavy industrial applications, such as oil sands, heavy oil processing, refining and petrochemical facilities, our chemical products and processes often replace more expensive mechanical methodologies for projects like vessel, tank, and heat exchanger cleaning. Applications may vary from large-scale plant maintenance work to very minor issues such as odour control.

Our customized approach and superior research and development:

Slashes operating, maintenance and environmental costs
Saves time and builds a more efficient facility
Delivers peace of mind on critical projects
Provides guaranteed support from dedicated and accountable experts

Types of Chemistries:

Aqua-milling, also known as water jetting, retro-jetting or hydro-jetting, is an efficient method of cleaning industrial piping through the implementation of high-pressure water nozzles and jets.

Newly installed process piping typically contains foreign debris. These residual deposits can compromise system reliability and lead to premature system degradation and failure during plant operation. In order to help preserve the long term integrity of these process piping systems, hydro-milling can be used to remove all undesirable foreign contaminants and particulate matter.

Aqua-milling has been proven as an effective means of removing both large and fine debris from piping surfaces, including post-construction debris, by-products that result during fabrication, and operation derived deposits, which are comprised of welding slag, mill-scale, loose rust, and mineral sediment.

Benefits of Aqua-milling:

Reduced commissioning (i.e., steam blows) durations on boiler feedwater and steam systems
High degree of cleanliness on non-critical and critical systems
Can be completed in a variety of conditions, including sub-zero climates
Removes both fine and large particles
Lower water requirements compared to conventional water flushes
Water recycling capability with minimal waste disposal requirements
Reduced costs associated with time and scheduling

Degassing and decontamination is a single step process designed for fast and efficient—and therefore economical—process plant cleaning.

Enhanced steaming technique in which chemicals are injected into the steam stream to clean large process vessels, reactors, exchangers, and interconnecting piping.
Used for post-operational cleaning to remove H2S (hydrogen sulphide), benzene, LELs, pyrophoric iron, mercaptans, and ammonia
Reduces the hazards of dangerous gaseous elements inside petro-chemical processing equipment.
Decontamination (solvent circulation) precedes degassing to minimise the source of contamination (e.g., sludge, heavy deposits, etc.).
Harpers’ chemicals are specifically designed to provide a safe environment for vessel maintenance and our process reduces both the amount of waste and human exposure to dangerous substances during cleaning and maintenance work.

Pigging is completed to maintain efficiency and provide actionable insight to avoid potential problems on existing pipelines. It is often applied to remove new construction debris and assist during hydrostatic testing by dewatering and drying the pipeline.

Upon completion of piping construction, the line is required to be tested beyond its required operational pressure. Testing can be completed pneumatically with air or nitrogen, or it can be completed with fluids such as water, glycol, or a water/methanol mixture.

We offer all forms of testing, with the experience to complete testing from design to infield completion. For every test conducted, we provide an engineered test procedure to be executed, as well as engineering support throughout.

Applications Within The Energy Industry:

Harpers have the specialist equipment and personnel to carry out the cleaning, decontamination and removal of both hazardous and non-hazardous contaminants in drains, sewers, interceptors and lagoons.

Our teams will carry out a site survey, risk assessment, produce a method statement and analyse the waste to be removed
High performance vehicles and accessories from our specialist fleet can work at depths of up to 60 metres, via openings of just 100 millimetres, toremove large volumes of liquid waste quickly and efficiently.
Our jetter recycling units can operate as an air mover or conventional vacuum unit together with the continuous recycling of water. This enables the unit to spend more time on the cleaning process before replenishing the jetting water.
If large volumes of waste are to be lifted from lagoons or interceptors, the waste can be processed on site using our mobile or static filter presses.
The modern day filter press removes the filtrate from the sludge and changes it into a dry filter cake. The filtrate can either be reused on site or disposed of to drain, cutting disposal costs and returning impressive savings.
Deterioration of drains and sewers can take place for many different reasons but by providing a CCTV survey, Harpers can quickly identify the reason for the problem and make recommendations on the best possible solution.

Harpers work with both hazardous and non-hazardous waste and bring best practice approaches to cleaning processes
We implement a robust methodology to waste reduction and presentation of waste streams for final disposal routing.
We are driven by the requirements of the waste hierarchy, the EA’s established expectations on how industry should approach waste generation and disposal
