After the earthquake of February 27, 2010, SVTI required a survey of the damage caused by the earthquake. PA Engineering developed the studies and basic engineering to address these improvements. Then it executed the detailed engineering for the new berthing site No. 4, which was planned to be built next to site No. 3, a development framed in the general repair project of the Port.

Along with the projection of the esplanade to a new site, the designs of the slabs, crane support beams, earthworks and pile specification were contemplated.

Subsequently, PA Engineering developed the basic engineering for the standardization of the terminal’s fire protection system, and the construction support engineering for the rehabilitation of sites No. 2 and No. 3, the esplanade and container yard, repair of the Water Pond and revision of the fire protection system.

Panels Arauco S.A. built a new Medium Density Particle Board (MDP) plant. The project included the installation of two lamination lines for the production of melamine boards and an impregnation line for the preparation of the melamine papers required for the panel lamination process.

The nominal production capacity is 300,000 m3 of finished panels per year, with densities ranging from 600 to 760 kg/m3. The production capacity of melamine-coated boards is 250,000 m3 per year, and the capacity of the impregnation line will be 36,000,000 m2 per year.

Environmental Impact Statement

The F4F Talca plant receives and processes organic waste like domestic waste, producing proteins and oils of high nutritional and functional value, as well as bioinput for its application in the agricultural industry, through the cultivation of black soldier fly (Hermetia illucens).

The Plant currently has an authorized organic waste treatment capacity of 250 t/month and a current production of 5 t/month of flour.

Thus, PA Engineering Environmental Management prepared and submitted for evaluation, through an Environmental Impact Statement, a project that seeks to increase the capacity of the Talca plant, both in the reception and processing of organic waste from approx. 28 t/day to 100 t/day and the flour production capacity up to 100 t/month. The favourable resolution of the project was obtained within 8 months by a unanimous vote of approval.

This growth will involve, among other aspects, increasing the frequency of receiving organic waste; expanding the types of organic waste received and treated; and to increase both the storage capacity and the installed electrical power of the facilities. In addition, it may receive liquid waste for the process of preparing the food of the larvae, from the food industry (beverages or residual yeasts from the alcoholic fermentation process, from the agribusiness and livestock industry (residues from vineyards, fruits and vegetables), for a volume of 6.5 m3/day.

PA Engineering intervened in the proposal through the development of the conceptual engineering, estimating the investment necessary to carry out the project. Subsequently, we presented the basic engineering, in which the required processes were defined, then developed the detailed engineering in all disciplines and the management of the procurement of the equipment abroad.

Along with this work, the PA Engineering Environmental Management, worked on the archaeological survey and the obtaining of related environmental permits. Then the Engineering Management developed the construction program and provided the ground engineering, which allowed the required adjustments to be made to the details of the construction.

Processing of the EIS and Balance of Plant (BOP) engineering for the methanol-to-gasoline conversion process.

With the aim of accelerating the committed decarbonization, HIF set out to develop the first demonstration plant to generate E-Methanol and E-Gasoline from carbon dioxide (CO2) from the air and hydrogen (H2) from water, including a wind turbine, an electrolyzer for hydrogen generation, CO2 capture, methanol synthesis, the Methanol-to-Gasoline (MtG) process and the entire balance of plant (BOP) in the Magallanes Region.  Chile.

HIF built the Haru Oni demonstration plant. This is one of the first projects of its kind in the world. The plant obtains green hydrogen from water based on an electrolyzer powered by wind energy; then, the hydrogen is combined with CO2 captured from the atmosphere and through a synthesis process methanol is produced. The methanol produced is treated and then transformed into E-Fuel (MtG process), including carbon-neutral gasoline and carbon-neutral liquefied gas. These E-Fuels cement the way for existing infrastructure to be carbon neutral, through the continuous reuse of CO2.

PA Engineering developed the BOP engineering of the MtG Plant, performing the basic and detailed engineering in mechanical, piping, structural, electrical and instrumental and control necessary to complete the MtG System, including the MtG unit building, the Tank Farm, the electrical power system, the interconnections with the methanol plant,  truck loading systems and facilities for other supplies from the MtG and Tank Farm areas.

Environmental Impact Statement, architecture, basic and details engineering in civil, electrical, instrumentation, mechanics and processes

The project consisted of the recovery of CO2 carbon dioxide from an outlet gas stream (Tail gas), rich in CO2, hydrogen H2 and methane CH4, which was generated at the CHT Hydrogen Plant of ENAP Bío Bío Refinery. This current was returned to the reforming furnaces of the plant to be used as fuel, where the CO2 contained was released into the environment because of combustion.

PA Engineering participated in developing the Environmental Impact Statement in 2005, when this project began with the signing of an agreement between INDURA and ENAP Refineries, with the aim of reducing CO2 emissions in said refinery and thus accessing the issuance of Carbon Credits, tradable in the market to companies that are obliged to emit fewer Greenhouse Gases.  generating both economic and environmental benefits. 

PA Engineering performed basic and detail engineering in different disciplnes in 2007. The project considered the installation of a CO2 recovery plant from the Tail gas stream, which was composed of the necessary equipment to efficiently extract CO2 from said stream, for subsequent purification and liquefaction, with an approximate production of 3,600 tons/month.

In turn, Indura managed to reduce the use of fossil fuel (natural gas and propane) previously used to produce the CO2 it produces.

This project became the first plant to capture and produce CO2, based on a methodology developed by both companies approved by the Executive Board of the United Nations Clean Development Mechanism (CDM).

The Luz del Norte project is a solar photovoltaic (PV) power in 478 hectares of land, diversifying Chile’s energy portfolio.

The 141 megawatt (MW) alternating current project is powered by more than 1.7 million First Solar advanced thin-film PV modules, which produce enough solar energy to power 174,000 homes and displace the equivalent of more than 185,000 metric tons of CO2 emissions per year.

Grouped into four subsectors or PVCS units, each of these four PVCS units was connected to the substation considered in the project through a 23 kV collector. This new substation collects the plant’s 162 MW and connects it to the nearest existing substation in the system.
