The modular and standardized formulation of skid-mounted equipment as early as the 1960 s and 1970 s, a considerable number of countries abroad have begun to apply, especially in the United States, Britain, Japan and other countries, China started later, this technology has brought high economic and social effects to many engineering construction industries. They use a variety of skid-mounted equipment almost all use a full set of prefabricated modular complete sets of equipment.

Lever refers to a set of equipment fixed on a chassis made of angle steel or two-oxide steel, which can be moved and used in situ. It is a form of the overall combination of equipment frame and equipment, and is an integrated assembly of valves, pumps and other equipment. When connected to other equipment in the system, there is no need to assemble valves, instruments, etc. halfway. Only pipes need to be connected. Simple assembly, simple migration, production and assembly of skid-mounted equipment are all completed in the factory. The on-site assembly workload is small, and only the interface pipeline and external electrical connection are required. The skid-mounted equipment is tight and occupies a small area compared with the traditional assembly method.

1 "Modular, assembly skid, factory" advantage

1.1

3D modeling is simple and fast

In the process of project implementation, engineers carry out three-dimensional modeling of engineering equipment, process pipelines and steel structures, so that the visual formulation of equipment and operation, formulation, operation and operation personnel are clear at a glance.

1.2

Skid-mounted equipment graphic standardization

The use of skid-mounted formulation greatly shortens the formulation cycle of the device, improves the formulation quality of the device, effectively realizes the refinement and standardization of the formulation, and completes the formulation and optimization of many standard general drawings in the process of project formulation. These graphics can also be reused in other projects, which greatly reduces the development workload, greatly shortens the project engineering cycle, and can use skid modules multiple times and in large quantities.

1.3

Quantification of procurement, convenient operation and maintenance

After the equipment is assembled, it is beneficial to purchase a large number of materials and equipment. With the standardization of the formulation, project equipment, piping, instrumentation, electrical, equipment foundation, etc. can be finalized, and a large number of equipment and materials can be purchased, effectively saving costs and shortening the procurement cycle. Through modularization, the versatility and interchangeability of equipment and accessories are convenient for field operation and assembly. In the past, for fixed equipment assembled in the field, the supplier was usually not one, so the subsequent operation and maintenance costs and management were difficult. The problem of assembling equipment can be solved by the supplier in time, so as to improve the stability and reliability of the equipment operation and facilitate the maintenance of the equipment.

1.4 significant reduction in field operation time

The formulation of "standardization and modularization" realizes the standardization of the process flow. The process module realizes skid block and factory manufacturing. The equipment production and assembly are completed in the factory. The field assembly workload is small, and only the interface pipeline and external electrical connection are required. Functional components are integrated into the entire base to facilitate overall migration, which can solve some technical problems in the field to a certain extent.

1.5

Skid-mounted equipment to improve engineering quality

Standardized formulation avoids the probability of formulation errors and greatly reduces the rework of field operations. Standardized formulation of equipment, piping, instrumentation, electrical and other stereotypes, suppliers and operating units of the equipment requirements are very understanding, help to improve the quality of equipment processing and manufacturing and field operations of the assembly level. The factory prefabricated mature technology and advanced equipment make it easier to ensure the quality of the project. Standardized and modular formulation helps to improve the overall quality level of engineering construction.

1.6

Skid-mounted equipment to improve operation efficiency

Assembly formulation helps to improve the working environment and improve the efficiency of the operation. The "factory" formulation of process equipment reduces the limitations of bad weather on product quality and operation schedule, and greatly reduces the workload of field operations. Especially in the case of relatively poor natural conditions, can make full use of crowbar formulation. In the factory of production equipment, most of the equipment is assembled and debugged, which reduces the outdoor labor intensity of workers, helps to realize standardized operation management, and can greatly improve the operation efficiency.

2 Use of equipment applications

Skid-mounted equipment oily wastewater treatment device

At present, the research on oily wastewater treatment in oil fields at home and abroad is gradually developing from the research of process to the research direction of sewage treatment monomer equipment, the main goal is to improve the treatment efficiency and reduce the investment in oily wastewater treatment. The device adopts an assembly device, which is small in size, high in efficiency, small in assembly area, easy to assemble and use, and only about half of the fixed cost. It can not only save a lot of electricity, heat, water and other public works consumption, but also prevent crude oil external water pipelines from increasing. With the increase of water content and liquid volume, the direct economic benefits and potential benefits of skid-mounted equipment have obvious growth effects.
